  List recent webhooks/requests captured for a tunnel. Returns id, method, path, status and bodies.

  Parameters:

  • subdomain (required) — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• get_request read-only

  Get the full request and response (headers + body) of one captured webhook by id.

  Parameters:

  • subdomain (required) — string
  • id (required) — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• replay_request destructive

  Replay a captured webhook to the user's localhost (the tunnel CLI must be running).

  Parameters:

  • subdomain (required) — string
  • id (required) — string

  Hints: read-only no · destructive yes · idempotent no · open-world yes

• send_test_webhook destructive

  Send a generated test webhook to the user's localhost (the tunnel CLI must be running). Provide a `provider` (stripe, github, shopify, clerk, slack, resend, paddle, polar, lemonsqueezy) and optional `event` for a realistic sample payload, or pass a custom JSON `body`. Pro plan required.

  Parameters:

  • subdomain (required) — string
  • provider (required) — string
  • body — string — Custom JSON body (overrides the template)
  • event — string

  Hints: read-only no · destructive yes · idempotent no · open-world yes

• set_long_requests

  Opt a tunnel into a 120-second ingress timeout instead of the 30-second default — for tool calls that legitimately run long, e.g. an MCP server exposed through the tunnel. Persists on the tunnel; pass enabled: false to revert to the 30-second default.

  Parameters:

  • subdomain (required) — string
  • enabled (required) — boolean

  Hints: read-only no · destructive no · idempotent yes · open-world no

• set_ws_passthrough

  Opt a tunnel into WebSocket passthrough, so an application-level WebSocket connection (e.g. a mobile/web app's own realtime feature) can be relayed to your localhost. Pro/Team plan required to enable; pass enabled: false to disable on any plan.

  Parameters:

  • subdomain (required) — string
  • enabled (required) — boolean

  Hints: read-only no · destructive no · idempotent yes · open-world no

• list_api_collections read-only

  List the workspace's API collections (saved endpoints with examples and environments). Start here to find a collection_id.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• get_api_collection read-only

  Get one collection's folders, endpoints (id, method, path, name, version, example count) and environments (with their variables).

  Parameters:

  • collection_id (required) — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• get_api_endpoint read-only

  Get one endpoint in full: description, parameters, headers, request body, saved response examples and its current `version`. Identify it by endpoint_id or by method + path.

  Parameters:

  • collection_id (required) — string — Id from list_api_collections.
  • path — string — Route path as written in the code, e.g. /v1/charges/:id or /v1/charges/{id}.
  • method — string — HTTP method of the route, e.g. POST. Use with path instead of endpoint_id.
  • endpoint_id — string — Id of the endpoint. Alternative to method + path.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• create_api_collection

  Create an empty API collection. Prefer import_api_spec when there is an OpenAPI file, and upsert_api_endpoint to fill it from the code.

  Parameters:

  • name (required) — string
  • description — string

  Hints: read-only no · destructive no · idempotent no · open-world no

• upsert_api_endpoint

  Document an endpoint: creates it, or updates the existing one for the same method + path. Use it whenever you add or change a route in the code, so the docs stay true. Only the fields you send change. `path` may use :id, {id} or {{id}} for variables. `folder` is created by name if missing. Send `version` (from get_api_endpoint) to avoid overwriting a teammate's edit; a stale version is rejected.

  Parameters:

  • collection_id (required) — string
  • method (required) — string
  • path (required) — string
  • body — Example request body (any JSON). null clears it.
  • kind — string — `event` for a webhook your app sends.
  • name — string — Short title, e.g. Create a charge. Defaults to METHOD /path.
  • folder — string — Folder name, e.g. Charges.
  • params — array — Documented fields.
  • headers — array
  • version — integer
  • description — string

  Hints: read-only no · destructive no · idempotent yes · open-world no

• add_api_example

  Save a response example on an endpoint (for instance the 402 your handler returns for a declined card). Replaces the example with the same name, so it is safe to repeat.

  Parameters:

  • collection_id (required) — string — Id from list_api_collections.
  • name (required) — string — e.g. Card declined.
  • status (required) — integer
  • body — Example response body (any JSON).
  • path — string — Route path as written in the code, e.g. /v1/charges/:id or /v1/charges/{id}.
  • method — string — HTTP method of the route, e.g. POST. Use with path instead of endpoint_id.
  • headers — array
  • endpoint_id — string — Id of the endpoint. Alternative to method + path.
  • status_text — string

  Hints: read-only no · destructive no · idempotent yes · open-world no

• delete_api_endpoint destructive

  Delete an endpoint and its examples. Use when the route no longer exists in the code. Cannot be undone.

  Parameters:

  • collection_id (required) — string — Id from list_api_collections.
  • path — string — Route path as written in the code, e.g. /v1/charges/:id or /v1/charges/{id}.
  • method — string — HTTP method of the route, e.g. POST. Use with path instead of endpoint_id.
  • endpoint_id — string — Id of the endpoint. Alternative to method + path.

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• import_api_spec

  Import an OpenAPI 3.x document (as JSON), a Postman v2.x collection (JSON) or a curl command into a new collection, or into `collection_id`. All or nothing, and plan limits are checked first. Credentials are never imported (they become variables). Convert YAML to JSON before sending.

  Parameters:

  • format (required) — string
  • content (required) — The document (object or JSON string), or the curl command.
  • name — string — Name for the new collection.
  • collection_id — string — Add to this collection instead of creating one.

  Hints: read-only no · destructive no · idempotent no · open-world no

• export_api_collection read-only

  Export a collection as an OpenAPI 3.1 or Postman 2.1 document. Handy to read the whole API at once.

  Parameters:

  • collection_id (required) — string
  • format — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• run_api_endpoint destructive

  Send an endpoint against an environment and return the real response (status, headers, body up to 20 KB). A `local` environment goes through the user's tunnel to their localhost (the CLI must be running); staging/prod are sent from Pipehero's cloud (Pro/Team) to public addresses only. Sending to a `prod` environment with a write method needs confirm_write_to_prod: true, which you should only pass after the user agrees. Use it to check that the code you wrote behaves as documented.

  Parameters:

  • collection_id (required) — string — Id from list_api_collections.
  • environment (required) — string — Environment name or id, e.g. local.
  • path — string — Route path as written in the code, e.g. /v1/charges/:id or /v1/charges/{id}.
  • method — string — HTTP method of the route, e.g. POST. Use with path instead of endpoint_id.
  • variables — object — Values for {{variables}} the environment doesn't define, e.g. {"id": "ch_123"}.
  • endpoint_id — string — Id of the endpoint. Alternative to method + path.
  • confirm_write_to_prod — boolean

  Hints: read-only no · destructive yes · idempotent no · open-world yes

• save_captured_request

  Document a real request captured by a tunnel (get its id from list_requests). If an endpoint already covers the route, the response is added to it as an example; otherwise an endpoint is created from the request. Credentials, cookies and signatures are replaced by {{variables}} and only JSON bodies are kept. A response already saved as an example is not duplicated. Use it to document webhooks and calls you have only seen in traffic.

  Parameters:

  • collection_id (required) — string
  • tunnel (required) — string — Subdomain of the tunnel that captured the request.
  • request_id (required) — string — Id of the captured request, from list_requests.
  • path — string
  • folder — string — Folder for a newly created endpoint, created by name if missing.
  • method — string — With path: the endpoint that should receive the example.
  • endpoint_id — string — Add the example to this endpoint instead of matching by route. Alternative to method + path.

  Hints: read-only no · destructive no · idempotent yes · open-world no

• list_api_monitors read-only

  See which endpoints of a collection are checked on a schedule (Pro/Team monitors) and how they are doing: state (healthy, failing, blip, paused, waiting), the last check with its status, latency and error, and since when it has been failing. Use it to find out what is broken in staging or production, then read the endpoint and its code. Read-only: people decide what to monitor.

  Parameters:

  • collection_id (required) — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• list_api_proposals read-only

  See what happened to the changes you proposed. Some workspaces review AI changes: your write tools then answer `pending_review` and change nothing until a teammate approves. This lists the latest proposals with their status (pending, approved, rejected with the reviewer's reason, or failed with why) so you can tell whether a change went through.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• check_api_drift read-only

  Compare a collection's docs with the real traffic a tunnel captured (Pro/Team). Returns routes nobody documented, status codes with no example, response or request fields missing from every example (or with another type), undocumented query parameters, and documented fields that never appear. Each finding includes `request_id` of the newest request that shows it: pass it to save_captured_request to add it to the docs, or fix the docs with upsert_api_endpoint and add_api_example. Use it to find out what drifted after a code change.

  Parameters:

  • collection_id (required) — string
  • tunnel (required) — string — Subdomain of the tunnel whose traffic to compare.
  • limit — integer — How many recent requests to compare (default 200, max 500).

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• get_api_share_link read-only

  Get the shareable link of an endpoint (a read-only page with its docs, examples and latest run, secrets hidden), who can open it and who was invited. Use it to put the link in a PR, an issue or a message. Each endpoint has one link that never changes; `shared: false` means it has none yet (see share_api_endpoint).

  Parameters:

  • collection_id (required) — string — Id from list_api_collections.
  • path — string — Route path as written in the code, e.g. /v1/charges/:id or /v1/charges/{id}.
  • method — string — HTTP method of the route, e.g. POST. Use with path instead of endpoint_id.
  • endpoint_id — string — Id of the endpoint. Alternative to method + path.

  Hints: read-only yes · destructive no · idempotent not declared · open-world no

• share_api_endpoint

  Create an endpoint's shareable link and return it. With no other arguments the link stays restricted: workspace members can open it (they sign in), which is enough for a PR or an internal message. Only when the user asks to share it outside the workspace: set `link_access` to `viewer` (anyone with the link can read) or `commenter` (Team plan; commenting asks for sign-in), or `invite` people by email (they get an email and sign in with that address). `restricted` turns the public link off; the URL stays the same. The page is read-only and always hides credentials and secrets.

  Parameters:

  • collection_id (required) — string — Id from list_api_collections.
  • path — string — Route path as written in the code, e.g. /v1/charges/:id or /v1/charges/{id}.
  • invite — array — People to invite by email (at most 10). Each gets an email.
  • method — string — HTTP method of the route, e.g. POST. Use with path instead of endpoint_id.
  • endpoint_id — string — Id of the endpoint. Alternative to method + path.
  • link_access — string — Who can open it with just the link. Omit to keep the current setting (restricted for a new share).

  Hints: read-only no · destructive no · idempotent yes · open-world yes

• share_api_collection

  Share a whole collection: every endpoint in it (including ones added later), with its examples and latest run, read-only and with secrets hidden. Environments are never shown and it can't be exported. Returns the collection's link, which never changes. With no other arguments it stays restricted to the workspace; set `link_access` or `invite` people only when the user asks to share it outside the team. get_api_collection returns the link as `share` once it exists.

  Parameters:

  • collection_id (required) — string
  • invite — array — People to invite by email (at most 10). Each gets an email.
  • link_access — string — Who can open it with just the link. Omit to keep the current setting (restricted for a new share).

  Hints: read-only no · destructive no · idempotent yes · open-world yes

• list_api_runs read-only

  Recent runs of an endpoint (newest first, default 5): who/what was sent and what came back. Use to see what happened the last time it was run.

  Parameters:

  • collection_id (required) — string — Id from list_api_collections.
  • path — string — Route path as written in the code, e.g. /v1/charges/:id or /v1/charges/{id}.
  • limit — integer — 1 to 20.
  • method — string — HTTP method of the route, e.g. POST. Use with path instead of endpoint_id.
  • endpoint_id — string — Id of the endpoint. Alternative to method + path.
