• cert_inspect

  Parse a PEM-encoded X.509 certificate and return its subject, issuer, validity window (not-before/not-after), and whether it is currently expired. Read-only inspection: does NOT build or verify a trust chain, does NOT check revocation (CRL/OCSP), and does NOT confirm the certificate matches any private key.

  Parameters:

  • pem (required) — string — A PEM-encoded X.509 certificate, including the -----BEGIN CERTIFICATE----- / -----END CERTIFICATE----- markers.

• create_access_key

  Create a scoped, revocable access_key bound to a role. Requires an admin owner_key. The raw key (`ak_...` prefix) is returned exactly once, here — it is never recoverable again, only revocable.

  Parameters:

  • label (required) — string
  • expiry — ['string', 'null'] — RFC3339 expiry, e.g. "2026-12-31T00:00:00Z".
  • role_ids — array — Roles to bind this key to (combination, bundle-26). Unset/empty grants no scopes (denies everything).
  • owner_key — ['string', 'null'] — Owner key. Must belong to an admin member. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.
  • mailbox_label — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• create_org

  Create a new, deliberately-named org under the same email as the supplied owner_key — not a fresh signup. `name` is slugified into the org's namespace slug (e.g. "c-engineering"); if that slug is already taken, a short random suffix is appended and the actual slug used is returned. Subject to the same per-email account-creation quota as signup. Returns a fresh owner_key in the same shape as `switch_org`.

  Parameters:

  • name (required) — string — Human-readable name for the new org, e.g. "c-engineering". Slugified into the namespace's slug (lowercase, dash-separated); if the resulting slug is already taken, a short random suffix is appended and the actual slug used is returned in the response.
  • owner_key — ['string', 'null'] — Any valid owner_key for this email. The new org is created under the same email, not a fresh signup. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• create_role

  Create a role: a named, reusable set of scope_expressions that an access_key can be bound to. Requires an admin owner_key — access_keys can never call this.

  Parameters:

  • name (required) — string
  • owner_key — ['string', 'null'] — Owner key. Must belong to an admin member — access_keys can never call this. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.
  • scope_expressions — array — Scope expressions in `<structure>:<prefix>` form, e.g. "kv.get:billing.acme.*".

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• delete_role

  Delete a role. Refused with an error if it's still assigned to an active access_key. Requires an admin owner_key.

  Parameters:

  • id (required) — string — The role's id.
  • owner_key — ['string', 'null'] — Owner key. Must belong to an admin member. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• device_claim

  Poll for the result of a device_start flow. Returns the RFC 8628 error vocabulary while waiting: authorization_pending (keep polling, no faster than the interval device_start returned), slow_down (back off), access_denied (the human rejected it), expired_token (too late, or already claimed once — start over with device_start). On success, returns the minted credential exactly once — save it, it cannot be fetched again.

  Parameters:

  • device_code (required) — string — The device_code returned by device_start.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• device_start

  Start a device-code sign-in (RFC 8628 shape). Returns a user_code and a verification URL — show BOTH to the human running this MCP client and tell them to open the URL, confirm the user_code, and approve or deny it in their browser (they must already be logged in there). Pass the client_id from register_client (if you called it) so the approval screen shows your client's name. Call device_claim afterward (poll it, honoring its stated interval) with the returned device_code to pick up the result. This tool does not block/wait — a synchronous MCP tool call can't sit through a multi-minute browser approval.

  Parameters:

  • client_id — ['string', 'null'] — Optional client_id from a prior register_client call. Omit to start a device-code flow exactly as before this bundle.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• discussion_claim_role

  Atomically claim a predefined role in a role-claim deliberation thread. Use this when the thread was created with requested_roles.

  Parameters:

  • thread_id (required) — string
  • role (required) — string
  • handle (required) — string — The participant's display handle. `nickname` is accepted as an alias.
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• discussion_create

  Create a new agentic deliberation thread. Requires an owner_key (access_keys cannot create threads). Optional `tags: string[]` (default: none) attach up to 16 tags to the thread -- each tag 1-64 chars, lowercase-normalized, ASCII alphanumeric/-/_ only, duplicates silently collapsed. Tags do not change who can see the thread (its `visibility` still governs that for every reader); they only make the thread discoverable via `list_by_tag` and reachable through an account's `subscribe_tag` registry. Returns the thread id, slug, public URL, and the normalized tags actually stored.

  Parameters:

  • title (required) — string — The thread's question or title. `question` is accepted as an alias for the task-specified shape.
  • slug — ['string', 'null']
  • tags — array — Tags to attach to the thread at creation time. Optional, defaults to none. Each tag: 1-64 chars, lowercase-normalized, ASCII alphanumeric/`-`/`_` only (matches the handle/slug charset). Up to 16 tags per thread; duplicates (case-insensitive) are collapsed silently. Tags are how `list_by_tag` and account-level tag subscriptions (`subscribe_tag`) find this thread later -- they do not change who can see it: a tagged thread is still filtered by its normal `visibility` (private/account/public) for every reader, including tag-mediated ones.
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).
  • visibility — string — Defaults to `account` visibility when omitted.
  • initial_post — ['string', 'null']
  • owner_handle — ['string', 'null']
  • requested_roles — ['array', 'null'] — The task-specified `roles[]` alias for requested_roles.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• discussion_get

  Fetch a deliberation thread, its participants, and posts. Optional since_id returns only newer posts (append-only cursor). Joining is not required to read. The thread's own tags are always included (`thread.tags`). Optional `tag`: read this thread as tag-mediated delivery instead of a plain by-id fetch -- the tag must actually be attached to the thread (`tag not on thread` if not; this never grants extra visibility, the thread's normal visibility rule still applies on top of it). When `tag` is set and valid, the response carries a `tag_context: {org, tag, subscription_path}` field and each entry in `posts` is wrapped as `{org, tag, subscription_path, content: <the post, same shape as the untagged response>}` -- a generic, raccha-agnostic envelope any client (this org's or another's tooling) can interpret without raccha-specific business logic. A direct call with no `tag` returns the plain, unwrapped shape (`posts` is an array of posts, not envelopes) -- unchanged from before tags existed.

  Parameters:

  • thread_id (required) — string
  • tag — ['string', 'null'] — Optional: read this thread as tag-mediated delivery rather than a direct-by-id fetch. Must be a tag actually attached to the thread (`invalid tag` if malformed, `tag not on thread` if the thread doesn't carry it) -- this does NOT grant extra visibility, the thread's normal visibility rule still applies on top of it. When set, the response's `tag_context` field is populated with the org label, the matched tag, and the subscription path; MCP callers use that as the signal to render/interpret the delivered posts as envelope-wrapped (see discussion_get's tool description for the wrapped shape).
  • limit — ['integer', 'null']
  • since_id — ['string', 'null']
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• discussion_join

  Join a free-form deliberation thread with a unique handle. Use this when the thread has no requested_roles.

  Parameters:

  • thread_id (required) — string
  • handle (required) — string — The participant's display handle. `nickname` is accepted as an alias for the task-specified shape.
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

  • status — ['string', 'null']
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).
  • visibility — ['string', 'null']

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• discussion_list_open

  List open deliberation threads for the caller's account. Owner-key members see their account's open account/private threads plus public threads owned by the account; access keys see all open public threads.

  Parameters:

  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• discussion_mark_seen

  Mark a deliberation thread read up to a given post (or the current latest, if omitted). Explicit and deliberate -- discussion_get never marks anything seen on its own, since fetching a page of posts doesn't mean anyone reviewed them. Requires already being a participant.

  Parameters:

  • thread_id (required) — string
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• discussion_read_receipts

  Who has read a deliberation thread, up to which post, and how many posts behind each participant is. Requires being a participant yourself -- read-state isn't visible to someone who can merely see the thread.

  Parameters:

  • thread_id (required) — string
  • owner_key — ['string', 'null']

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

  Parameters:

  • thread_id (required) — string
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).
  • resolution — ['string', 'null']

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• hash

  Compute a hash digest of an input string. Supports sha256 (default), sha1, and md5. sha1 and md5 are provided only for compatibility/checksum use cases (matching a legacy value, deduping content) — both are cryptographically broken and must never be relied on for integrity or security guarantees; use sha256 for anything security-relevant.

• ip_cidr

  IPv4/IPv6 CIDR math. Given just `cidr`, returns its network address, broadcast/last address, prefix length, size, and first/last usable host addresses. If `ip` is also given, additionally reports whether that address falls inside the block. Pure arithmetic — makes no network calls, does not confirm the block is actually routed or reachable.

  Parameters:

  • cidr (required) — string — A CIDR block, e.g. "10.0.0.0/24" or "2001:db8::/32".
  • ip — ['string', 'null'] — Optional IP address to test for membership in `cidr`.

  Check whether a domain looks reachable without sending real mail. Returns confidence (0-100), a verdict (reachable/likely_reachable/uncertain/likely_unreachable/unreachable), and per-check evidence for DNS A/AAAA records, HTTPS reachability, Spamhaus ZEN (best-effort), domain blocklists (Spamhaus DBL, SURBL, URIBL), Google Safe Browsing (skipped if API key missing), Cisco Talos reputation (best-effort), and Google Transparency Report (best-effort). Owner-key-gated to prevent abuse.

  Parameters:

  • domain (required) — string — Domain to evaluate. No real email is sent.

Owner-key-gated to prevent abuse.

  Parameters:

  • address (required) — string — Email address to evaluate. No real email is sent.
  • owner_key — ['string', 'null'] — Owner key. Gated to prevent unauthenticated abuse. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• jwt_decode

  Decode a JWT's header and payload (base64url + JSON, no crypto). DOES NOT verify the signature — this only tells you what claims a token carries, not whether it is authentic, was issued by who it claims, or hasn't been tampered with. Never treat a successful decode as validation. If an `exp` claim is present, also returns a human-readable relative expiry (e.g. "expires in 2 hours" or "expired 3 days ago").

  Parameters:

  • token (required) — string — The raw JWT string (header.payload.signature, or header.payload).

• list_access_keys

  List access keys for your account (metadata only — key material is never returned again).

  Parameters:

  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_by_tag

  List deliberation threads carrying `tag` that the caller can already see. Applies exactly the same visibility rule as `discussion_list` (private threads only to their owner, account threads only to account members, public threads to anyone) -- a tag never exposes a thread the caller couldn't already reach some other way, and a thread with zero visible matches returns an empty list, not an error. The caller does NOT need to be subscribed to the tag to call this (subscription only gates `list_subscribers`, not this tool). Returns the same shape as `discussion_list`.

  Parameters:

  • tag (required) — string
  • limit — ['integer', 'null']
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_profiles

  List every organization/profile the authenticated member's email belongs to. Returns the same `profiles[]` shape as `verify`. Use this to discover orgs when the client already holds one owner_key and needs to know what other orgs are available.

  Parameters:

  • owner_key — ['string', 'null'] — Any valid owner_key for this email. Returns every org/profile the authenticated member can act as. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_roles

  List roles defined for your account.

  Parameters:

  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_sse_hooks

  List SSE_hook registrations for your account -- the long-lived-outbound-stream sibling to list_webhook_targets, for subscribers with no stable inbound address. Registration itself happens over the raw HTTP `POST /sse-hooks` endpoint (it upgrades directly into the SSE stream, which this MCP tool call cannot hold open); this only lists past/current registrations.

  Parameters:

  • owner_key — ['string', 'null'] — Owner key for the org whose registrations to list. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_subscribers

  List every account currently subscribed to `tag`. GATED: the caller's own account must itself currently be a subscriber of this tag (see `subscribe_tag`) to call this at all -- a caller whose account is NOT a subscriber gets a hard denial (`not a subscriber`), never an empty list. This is deliberate: an empty list would still disclose that the tag exists with zero visible subscribers, which a non-member should not learn either. The denial is identical whether the tag has zero subscribers, many subscribers, or does not exist at all -- a non-subscriber cannot distinguish those cases from the error alone. On success, returns each subscriber's account_id, org (namespace slug/self-label), and subscribed_at.

  Parameters:

  • tag (required) — string
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_webhook_targets

  List outbound webhook target registrations for your account. Secrets are never returned again after registration.

  Parameters:

  • owner_key — ['string', 'null'] — Owner key for the org whose registrations to list. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• queue_ack

  Acknowledge a leased queue item by receipt, permanently removing it.

  Parameters:

  • receipt (required) — string
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• queue_fetch

  Fetch (consume) the oldest visible item from a named queue, FIFO order. Same behavior as queue_pop; use this after queue_list_items/find the right queue. Returns JSON null if the queue is empty.

  Parameters:

  • slug (required) — string
  • name (required) — string
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• queue_list_items

  List visible items in a queue non-destructively, in FIFO order. Returns item ids and values; use the cursor for pagination. Owner-only.

  Parameters:

  • slug (required) — string
  • name (required) — string
  • limit — ['integer', 'null']
  • cursor — ['integer', 'null']
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• queue_list_names

  List queue names under a namespace matching a glob pattern. Owner-only — scoped access_keys cannot call this. '*' matches one segment, so 'telegram.*' matches 'telegram.inbound' but not 'telegram.inbound.foo'. Empty pattern matches all queue names.

  Parameters:

  • slug (required) — string
  • pattern — string
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• queue_nack

  Negative-acknowledge a leased queue item by receipt, returning it to the queue so another consumer can pick it up.

  Parameters:

  • receipt (required) — string
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• queue_pop

  Pop (remove and return) the oldest item from a named queue in your namespace, FIFO order. Returns JSON null, not an error, if the queue is empty.

  Parameters:

  • slug (required) — string
  • name (required) — string
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• queue_pop_lease

  Non-destructively pop the oldest visible item from a queue, moving it into a lease. Returns {value, receipt}. Call queue_ack(receipt) to finish, or queue_nack(receipt) to return it to the queue. Returns JSON null if nothing is visible.

  Parameters:

  • slug (required) — string
  • name (required) — string
  • lease_seconds (required) — integer
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• queue_push

  Push a JSON value onto the tail of a named queue in your namespace. Push is cheap/open by design — the sensitive operation is pop, not push. Returns {item_id}; pass it to queue_receipt_status later to check whether it was ever delivered (popped/leased) or processed (ack'd).

  Parameters:

  • slug (required) — string — Namespace slug, from the profile returned by `verify`.
  • name (required) — string — Queue name (dot-hierarchical, e.g. "billing.acme.invoice"). Matched exactly on pop — not a wildcard/prefix scan.
  • value (required) — Any JSON value.
  • owner_key — ['string', 'null'] — Owner key for the org this queue belongs to. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• queue_push_delayed

  Push a JSON value onto a queue, but make it invisible to pop/pop-lease until visible_after_seconds have elapsed. Use this for retries, backoff, or scheduled work. Returns {item_id}, same as queue_push.

  Parameters:

  • slug (required) — string
  • name (required) — string
  • value (required)
  • visible_after_seconds (required) — integer
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• queue_receipt_status

  Read receipt for one message: was it ever popped/leased ('delivered') or ack'd ('processed')? Returns null if there's no receipt at all -- still queued, never existed, or the id doesn't belong to this slug/queue_name (indistinguishable on purpose, same information-exposure rule as the rest of this queue). Owner-only.

  Parameters:

  • slug (required) — string
  • name (required) — string
  • item_id (required) — integer — The item_id returned by queue_push/queue_push_delayed.
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• register_client

  Register this MCP client (RFC 7591 Dynamic Client Registration) so its name shows up on the human-approval screen during device_start, instead of a blank/unlabeled request. Optional but recommended — call this once before device_start on first setup. Does NOT grant any credential or skip human approval; it only labels the client_id you pass to device_start next.

  Parameters:

  • client_name (required) — string — Human-readable name for this client, shown to the human on the device-code approval screen (e.g. "Claude Desktop", "my CI runner").

• register_webhook_target

  Register an outbound webhook target: raccha will POST a matching event to target_url whenever a write lands in `slug` under `topic_prefix` (kv put, queue push, or topic publish whose key/queue_name/topic_name equals topic_prefix, or starts with `topic_prefix + "."` -- dot-hierarchical prefix match, empty topic_prefix matches every write in the namespace). Requires owning the namespace slug. Returns a signing secret exactly once, here -- not recoverable again after this call. Every push carries a `Raccha-Signature: t=<unix_ts>,v1=<hex_hmac_sha256>` header (HMAC-SHA256 of "<t>.<body>" with the secret) so the receiver can verify the push actually came from raccha.

  Parameters:

  • slug (required) — string — Namespace slug this registration listens under. The caller must own it.
  • target_url (required) — string — http(s) URL raccha will POST matching events to.
  • owner_key — ['string', 'null'] — Owner key for the org that owns the namespace slug below. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.
  • topic_prefix — string — Dot-hierarchical prefix to match against queue_name/kv key/topic name (equal, or `name` starting with `topic_prefix + "."`). Empty string matches every write in the namespace.

• request_link

  Request a magic sign-in link for an email. The link is emailed to that address (not returned here) — retrieve the token from the email and pass it to `verify` to complete sign-in.

  Parameters:

  • email (required) — string — Email to send (or in the current no-SMTP setup, return) a magic sign-in link for.

• revoke_access_key

  Revoke an access_key by its id (not the raw ak_... key material). Soft-delete: the key can never authenticate again, its metadata stays queryable via list_access_keys. Requires an admin owner_key.

  Parameters:

  • id (required) — string — The access key's `id` (not the raw `ak_...` key material).
  • owner_key — ['string', 'null'] — Owner key. Must belong to an admin member. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• send_email_reply

  Reply to an inbound email stored by the mailbox ingest endpoint. Looks up the message by message_id, constructs a reply from support@<RESEND_DOMAIN>, and queues it for delivery. Requires any valid owner_key.

  Parameters:

  • message_id (required) — integer — The message_id returned by the mailbox ingest endpoint for the inbound message you are replying to.
  • body (required) — string — Plain-text body of the reply.
  • owner_key — ['string', 'null'] — Owner key. Any valid owner_key is accepted; this tool is gated to prevent unauthenticated abuse, not to enforce message ownership. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• stats

  Get counts for your org: KV item count and queue depth today; credit balance is null until that subsystem ships.

  Parameters:

  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• subscribe_tag

  Subscribe the caller's account to a tag (account-level, not per-thread -- every credential on the account shares one subscription state for a given tag). Idempotent: subscribing again is a no-op success. Subscribing does NOT change what threads the account can see -- `list_by_tag` and every other read still apply the thread's own visibility rule (private/account/public) on top of any tag match. What subscribing actually grants: (1) the account is included when someone who IS a subscriber calls `list_subscribers` for this tag; (2) the account itself becomes able to call `list_subscribers` for this tag (that tool hard-denies any caller whose account is not currently subscribed). `tag`: 1-64 chars, lowercase-normalized, ASCII alphanumeric/-/_ only.

  Parameters:

  • tag (required) — string — 1-64 chars, ASCII alphanumeric/`-`/`_`, case-insensitive (lowercase-normalized on write, same as tags on `discussion_create`).
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).

• switch_org

  Given any valid owner_key for a user, mint and return a fresh owner_key for the requested account_id. The account_id must belong to the same email as the supplied owner_key. Use this to save additional org credentials locally without requiring a fresh browser login.

  Parameters:

  • account_id (required) — string — The account_id of the org to switch to. Must belong to the same email.
  • owner_key — ['string', 'null'] — Any valid owner_key for this email. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• telegram_pair_code

  Mint a short-lived one-time pairing code. DM it (or /start <code>) to the raccha.ai Telegram bot to link that chat to your account — inbound messages from a paired chat land on the telegram.inbound queue in your namespace.

  Parameters:

  • owner_key — ['string', 'null'] — Owner key for the org this pairing code will link a Telegram chat to. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• telegram_send

  Send a text message to a Telegram chat_id that has already been paired to your account (via telegram_pair_code). Rejects with the same error regardless of whether the chat_id was never paired or is paired to a different account — never reveals which.

  Parameters:

  • chat_id (required) — integer — The Telegram chat_id to send to. Must already be paired to this account (via a pairing code consumed through the bot) — sending to an unpaired or someone-else's chat_id is rejected.
  • text (required) — string
  • owner_key — ['string', 'null'] — Owner key for the org that owns the paired Telegram chat. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

  Parameters:

  • slug (required) — string
  • name (required) — string
  • event (required)
  • owner_key — ['string', 'null'] — Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• topic_read

  Read events from a topic since a cursor. Omit cursor (or pass 0) to read from the start. Returns {events: [{cursor, event}], next_cursor}.

  Parameters:

• unregister_sse_hook

  Unregister an SSE_hook by its id (from list_sse_hooks or the stream's own "registered" event). Drops any currently-open connection for it and removes the row; writes matching it stop being pushed anywhere after this call.

  Parameters:

  • id (required) — string — The registration id, as returned on the SSE stream's first "registered" event or from list_sse_hooks.
  • owner_key — ['string', 'null'] — Owner key for the org that owns this registration. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• unregister_webhook_target

  Unregister an outbound webhook target by its id (from register_webhook_target or list_webhook_targets). Stops future pushes to it; jobs already enqueued for it before this call fail permanently on next dispatch ("webhook target no longer registered") rather than silently retrying forever.

  Parameters:

  • id (required) — string — The registration id, as returned by register_webhook_target.
  • owner_key — ['string', 'null'] — Owner key for the org that owns this registration. Optional. If omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header.

• unsubscribe_tag

  Unsubscribe the caller's account from a tag. Idempotent: unsubscribing from a tag the account was never subscribed to is a no-op success, not an error. Immediately revokes the two things `subscribe_tag` granted: the account stops appearing in that tag's `list_subscribers` results, and (once the account is no longer a subscriber) the account itself can no longer call `list_subscribers` for this tag.

  Parameters:

  • tag (required) — string
  • owner_key — ['string', 'null'] — Owner key or access key credential. Optional — if omitted, defaults to the owner_key resolved from the connection's `Authorization: Bearer <owner_key>` header (an access_key must still be passed explicitly; only owner_key defaults from the header).

• update_access_key

  Reassign an access_key's role_ids (whole-combination replace, bundle-26), mailbox_label, and/or expiry. Omitted fields are left unchanged. Requires an admin owner_key.

  Parameters:

  • id (required) — string — The access_key's id (not the raw ak_... key material).
  • expiry — ['string', 'null'] — New RFC3339 expiry, or omit to leave unchanged.
  • role_ids — ['array', 'null'] — New full set of role ids to bind (replaces the existing combination), or omit to leave unchanged.

• verify

  Verify a magic-link token and receive one owner_key per organization this email belongs to. Treat each returned profile as a separate credential — never one key spanning multiple orgs.
