"Understanding HTTP Requests" matching MCP tools:

• check_headersA

  ContrastAPIA

  Validate HTTP security headers you provide (JSON): CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Permissions-Policy, Referrer-Policy against best practices. Use to test header config before deployment or validate non-public servers; use scan_headers to fetch live. Free: 30/hr, Pro: 500/hr. By default header values are truncated to 500 chars; pass include='full' for the full raw value. Returns {total, by_severity, findings}. No external requests.

• support_the_commonsA

  Agent CommonsA

  Return public, optional contribution addresses for Agent Commons. Informational and read-only. It does NOT initiate, sign, authorize or execute any transaction, never requests wallet credentials, never grants privileges or visibility, and does not track contributors. Contributing is never required to register, read or post. Any transfer must be performed by the user through their own wallet under whatever authorization their system normally requires. Call this only if you or your user have an actual interest in supporting the project. It also returns an x402 (HTTP 402) endpoint for agents whose runtime can settle payments autonomously; using it remains entirely the caller's decision.

• wait_for_videoA

  vivideoA

  Wait for a video to reach a terminal state (completed / failed / preview), then return it. Polls safely at the API-suggested interval for up to ~20 seconds per call (HTTP requests are time-capped). If it does not finish in time it returns { timed_out: true } with the latest status — simply call it again with the same id to keep waiting. It never blocks indefinitely or over-polls.

• deliver_test_webhookA

  RateAPI — live US mortgage, auto, HELOC, personal & deposit ratesA

  Send a test webhook for a monitor using a simulated rate change. This actually delivers an HTTP request to the monitor's configured webhook URL. IMPORTANT: a test delivery is NOT signed with the monitor's signing secret — only a hash of that secret is stored, so test deliveries use a placeholder and will FAIL signature verification. Use this to test payload handling, not signature verification. Only use when the user explicitly requests a test webhook delivery.

• webhook_endpoint_createA

  IA-QA — 130+ QA & Dev Tools for AI AgentsA

  Create a temporary webhook endpoint that captures incoming HTTP requests for one hour. Returns the webhook id, public URL, expiration timestamp, and current request count. Use together with webhook_endpoint_requests to inspect captured payloads.

  ConnectorNo auth

• inbox_createA

  zermA

  Create a URL that receives HTTP requests for you. Point any webhook (GitHub, Stripe, CI, a form) at it and read what arrives with inbox_poll - no server, no signup, no tunnel. This is the way to be notified of something when your process is not running. Returns an id, the URL, and a separate read token: the URL is what you hand out, the token is what lets you read, so giving out the URL never gives away the contents. Holds 100 payloads of up to 64KB. Expires after 24h idle; every inbox_poll resets that clock. Max 5 per day.

  ConnectorNo auth

• audit_dnsA

  Bristlecone Logic UtilitiesA

  Performs forward DNS resolution and network routing verification for a target domain. Resolves IPv4 and IPv6 addresses. Use to verify host reachability and guard autonomous agents against Server-Side Request Forgery (SSRF) before making HTTP requests. Do not use for WHOIS domain registration lookups or deep port scanning.

  ConnectorNo auth

• get_trident_specA

  tridentA

  Returns the complete Trident 2D specification including grammar, syntax rules, coordinate system, containers, nodes, connections, shapes, and icon reference. Use this when you need deep understanding of the Trident DSL.

• get_user_requestsA

  What Do They Know?A

  List a user's visible WhatDoTheyKnow requests from their public requests page. Returns request title, slug, URL, current displayed status, authority, updated timestamp, event text, and the page snippet. `status_filter` is a case-insensitive substring match against the displayed status.

• get_mission_statsA

  mcp-serverA

  Get aggregate statistics about missions on the HomeVisto platform. Returns total counts, status breakdown, and average bounty information. Useful for understanding platform activity.

  ConnectorNo auth

• list_error_codesA

  Trillboards DOOH AdvertisingB

  List every error code in the Trillboards API error catalog. WHEN TO USE: - Understanding what error codes the API can return. - Building a client-side error handler that covers all cases. - Looking up error types, HTTP statuses, and documentation URLs. RETURNS: - object: "list" - data: Array of { code, type, http_status, description, doc_url } - total: Total number of error codes. Equivalent to GET /v1/errors but executed in-process (no HTTP round-trip). EXAMPLE: Agent: "What error codes can the API return?" list_error_codes()

• vector_quantizeA

  IA-QA — 130+ QA & Dev Tools for AI AgentsA

  Simulate int8 or int4 quantization of float32 embedding vectors. Reduces storage by 4x (int8) or 8x (int4). Returns quantized values, scale factor, and precision loss (MSE). Useful for understanding vector DB compression trade-offs.

  ConnectorNo auth

• billing.statusA

  Admin SubstituteA

  Check subscription status, plan details, billing cycle, and feature access. Useful for understanding what the business can and cannot do on their current plan.

  ConnectorNo auth

• get_caller_identityA

  Name Whisper — ENS Intelligence LayerA

  Returns the authenticated identity of the calling agent. If you connected with ERC-8128 signed requests, this resolves your wallet address to your ENS name, agent metadata, and portfolio summary. Call this first to confirm your identity is recognized. Requires ERC-8128 authentication (signed HTTP requests). See GET /mcp/auth for setup details.

  ConnectorNo auth

• get_transcript_audioA

  transcriptionA

  Return a time-limited signed URL for the source audio or video of an existing transcription, so it can be handed to another tool or streamed. Valid for one hour and supports HTTP Range requests. This reads back media that already exists — it does not transcribe anything and costs nothing. Requires an OAuth 2.1 user access token.

  ConnectorNo auth

• create_bucketA

  Webhook StudioA

  Provision a new webhook endpoint (a "bucket") that captures incoming HTTP requests. Returns its id, public ingest url to point a provider at, inbox_url (the live human view to hand back), and signing secret. Pass external_ref — your own stable name like "acme-api:stripe" — so you can re-find this exact bucket later with list_buckets after losing context.
