Measured tools (33)

• vc_web_search read-only

  Run a public web search and return titles, URLs, and snippets as JSON. Use when you need current public web results for a query. Do not use for private/intranet pages — call vc_page_markdown with a known URL instead. Sibling: vc_page_markdown (one URL), pay (generic slug caller). Auth: free-trial or prepaid X-Vibes-Key preferred; else USDC via x402 (~$0.02). Side effects: outbound HTTP to a search provider; no local writes. Returns JSON results, or a payment_required challenge if unpaid.

  Parameters:

  • query (required) — string — Search query string.
  • max_results — integer — Max results to return (typical 1–10).
  • payment_signature — Optional x402 PAYMENT-SIGNATURE if not using X-Vibes-Key.

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

• vc_page_markdown read-only

  Fetch a public webpage and return clean markdown plus extracted text. Use when you already have a URL and need readable page content for an LLM. Do not use for search discovery — call vc_web_search first. Not for authenticated or paywalled pages. Auth: free-trial or X-Vibes-Key preferred; else x402 (~$0.02). Side effects: outbound HTTP GET to the URL; no local writes. Returns JSON with markdown/text fields, or payment_required.

  Parameters:

  • url (required) — string — Public https URL to fetch and convert.
  • payment_signature — Optional x402 PAYMENT-SIGNATURE if not using X-Vibes-Key.

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

• vc_json_repair read-only

  Repair malformed JSON from LLM output and return valid parsed JSON. Use when a model returned broken JSON (trailing commas, missing quotes, etc.). Do not use for web fetching or search — use vc_web_search / vc_page_markdown. Auth: free-trial or X-Vibes-Key preferred; else x402 (~$0.02). Side effects: none local; compute-only remote call. Idempotent for the same text. Returns repaired JSON, or payment_required.

  Parameters:

  • text (required) — string — Malformed JSON or JSON-like text from an LLM.
  • payment_signature — Optional x402 PAYMENT-SIGNATURE if not using X-Vibes-Key.

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

• vc_agent_proof read-only

  Verify an agent's completion claim against real external world state. Runs independent read-back checks (HTTP status, page text, JSON fields) and returns a digest receipt with verified=true/false plus a confidence score, so a user does not have to trust the agent's self-reported summary. Use after an agent says it posted, deployed, paid, emailed or changed a record. ~$0.25/call.

  Parameters:

  • claim (required) — string — What the agent claims it did (its final report).
  • agent_id — Stable id for the agent being verified.
  • checks_json — string — JSON array of read-back checks, e.g. [{"name":"homepage live","url":"https://example.com/","expected_status":200,"contains":"Example"}]
  • payment_signature — Optional x402 PAYMENT-SIGNATURE if not using X-Vibes-Key.

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

• vc_lease_issue read-only

  Mint a durable single-use capability lease, or attenuate a parent lease. Use before an irreversible action you may need to retry: pass a stable use_nonce to vc_lease_consume so a retry after a timeout blocks instead of writing twice. Authority is conserved — a child's uses are reserved out of the parent, so a 1-use grant cannot father N free children. ~$0.05/call.

  Parameters:

  • holder (required) — string — Agent the authority belongs to. Use '*' for any holder.
  • action_scope (required) — string — Space-separated scope atoms the lease grants, e.g. 'read:repo write:issue'.
  • max_uses — integer — How many times this authority may be spent (1..10000).
  • ttl_seconds — integer — Seconds until expiry. Secondary check only: the ledger is the authority.
  • parent_lease_id — Attenuate from this parent: child scope must be a subset, and its uses are transferred out of the parent.
  • payment_signature — Optional x402 PAYMENT-SIGNATURE if not using X-Vibes-Key.

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

• vc_lease_consume read-only

  Spend exactly one use of a lease, atomically. Blocks replay, expiry, revocation and overuse. Returns decision allow/block with a named reason plus an Ed25519 decision receipt. If a previous attempt timed out, call this again with the SAME use_nonce: a replay returns reason=replay — do not retry the write, reconcile it. ~$0.02/call.

  Parameters:

  • use_nonce (required) — string — Stable id for this attempt (the replay key). Reuse the SAME nonce on retry.
  • action — What you are about to do, for the ledger trail.
  • agent_id — Caller identity; must match the lease holder unless it was issued to '*'.
  • lease_id — Lease to spend from.
  • lease_token — Signed lease token from vc_lease_issue (alternative to lease_id).
  • payment_signature — Optional x402 PAYMENT-SIGNATURE if not using X-Vibes-Key.

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

• vc_lease_revoke read-only

  Revoke a lease and (by default) its whole subtree so derived authority dies with its source. Use when an agent is misbehaving or a task is cancelled. ~$0.02/call.

  Parameters:

  • lease_id (required) — string — Lease to revoke.
  • reason — Why authority is being withdrawn (kept in the ledger).
  • cascade — boolean — Also revoke every descendant lease.
  • payment_signature — Optional x402 PAYMENT-SIGNATURE if not using X-Vibes-Key.

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

• vc_lease_status read-only

  Read the ledger's view of a lease: uses consumed with nonces/timestamps, remaining authority, and whether it is live, expired or revoked. ~$0.01/call.

  Parameters:

  • lease_id (required) — string — Lease to inspect.
  • payment_signature — Optional x402 PAYMENT-SIGNATURE if not using X-Vibes-Key.

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

• vc_agent_state_guard read-only

  Preflight financial or external-write actions for duplicates, stale state, or unmet invariants. Use before spending money or writing outside the agent sandbox. Do not use for generic search — use vc_web_search. Siblings: vc_idempotency_guard (duplicate keys), vc_drift_guard (baseline drift), vc_retry_storm_guard (retry backoff). Auth: X-Vibes-Key or x402 (~$0.02). Advisory only; no local writes. Returns GO/NO-GO style JSON with reasons, or payment_required.

  Parameters:

  • action (required) — string — Proposed action label (e.g. transfer, write_external, publish).

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

• vc_idempotency_guard read-only

  Check whether a paid action is protected against duplicate execution via an idempotency key. Use before retrying a payment or other side-effecting call. Do not use for content fetch — use vc_web_search / vc_page_markdown. Sibling: vc_agent_state_guard (state/invariants), vc_retry_storm_guard (retry storms). Auth: X-Vibes-Key or x402 (~$0.02). Advisory only; no local writes. Returns JSON assessing key presence/durability, or payment_required.

  Parameters:

  Search the Vibes-Coded marketplace for AI-agent tools and API outcomes. Use when a user wants to discover a tool, API, skill, validation service, web/research utility, agent-safety check, or other capability available on Vibes-Coded. Search by the user's actual task and return relevant listings. This tool only searches Vibes-Coded's bounded marketplace catalog. It does not execute a paid outcome, change user data, or search the general web. Prefer this before `pay` when the user has not already chosen a specific Vibes-Coded outcome.

  Parameters:

  • query (required) — string — What the user wants to accomplish, e.g. 'repair malformed JSON', 'verify an agent completed a deployment', or 'search the web'.
  • category — Optional marketplace category filter.

  • max_results — integer — Maximum matches to return, from 1 to 20.
  • max_price_usd — Optional maximum listed USD price per call.

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

• vc_marketplace_details read-only

  Get details for one Vibes-Coded marketplace resource. Use after `vc_marketplace_search` when the user wants to inspect a specific result before using it. Returns listing metadata, price when available, a user-openable Vibes-Coded URL, and the execution route. Read-only and does not execute or purchase the resource.

  Parameters:

  • slug (required) — string — Exact Vibes-Coded resource slug returned by vc_marketplace_search.

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

• vc_skill_scan_consensus read-only

  Reconcile conflicting agent-skill security scanner reports. Use after running two or more independent scanners. Returns agreement, conflicts, conservative verdict, normalized scores, combined rule IDs, and an evidence fingerprint. Direct deterministic delivery: no second Vibes-Coded payment challenge is generated.

  Parameters:

  • reports (required) — array — Two to ten reports: {scanner, verdict: allow|review|block, risk_score?, findings?}.

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

• vc_skill_risk_scan read-only

  Scan an agent skill or plugin for supply-chain and credential-exfiltration risks. Use before installing untrusted SKILL.md files, MCP plugins, npm packages, or setup scripts. Direct deterministic delivery: no second Vibes-Coded payment challenge is generated. Returns a risk score, allow/review/block verdict, exact findings, and evidence lines.

  Parameters:

  • content (required) — string — Complete SKILL.md, plugin manifest, installer, or source text to scan (max 200,000 characters).

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

• pay

  Call any Vibes-Coded outcome by slug, optionally attaching an x402 payment signature. Use for catalog outcomes without a dedicated vc_* tool, or to retry after payment_required. Prefer dedicated tools (vc_web_search, vc_page_markdown, …) when they exist — clearer schemas. Do not use instead of health(). Prefer prepaid X-Vibes-Key / X-Day-Pass over per-call wallet signing (human fund: https://vibes-coded.com/start). Args: slug: Outcome id, e.g. "web-search" or "agent-state-guard". payment_signature: Optional x402 PAYMENT-SIGNATURE header value. body: JSON object of endpoint fields (query, url, text, …). Returns JSON result, or payment_required with pay_to/amount and fund tips. Side effects: may settle USDC via x402 when paying; otherwise HTTP only.

  Parameters:

  • slug (required) — string — Outcome id, e.g. web-search or agent-state-guard.
  • body — JSON object of endpoint fields (query, url, text, …).
  • payment_signature — Optional x402 PAYMENT-SIGNATURE header value.

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

• health read-only

  Return MCP server liveness: version, origin, tool count, and catalog size. Use for hosted inspector probes (Glama / Smithery) or before diagnosing tool failures. Do not use for business outcomes — call vc_* tools or pay(slug=...) instead. No auth required. No side effects. Returns JSON {ok, service, version, origin, tools, catalog_resources}.
