"Generating a module in an iOS Xcode project using MVP with Coordinator architecture" matching MCP connectors:
GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Contract-change authorization for AI agents: preflight a change to an API or MCP contract, get a signed decision, and verify the receipt offline. Only a granted change can proceed.
Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
A webhook inbox for agents: one call returns a live URL. Mock, verify, inspect and replay.
Behind Check and GAIP Watch, and Diagnose: A2A, MCP and OpenAPI checks with a dated change log.
Retrieve YouTube transcripts with timestamps, native captions and asynchronous generation when captions are unavailable. Requires a Capslane API key.
Free platform to test MCP clients without installing anything. Create mock tools with dynamic templates, configurable delays, conditions (if/then), and response sequences. Supports JSON-RPC 2.0 over Streamable HTTP. Built-in text_echo and json_echo tools. Rate-limited tiers: anonymous (5 calls/min, 1 mock tool), registered (10 calls/min, 4 mock tools), premium (60 calls/min, unlimited). Zero setup — no install, no registration required.

AI-Powered Java/Spring Boot code review API with Alipay AI Pay support.
API documentation drifts away from the running service, so consumers integrate against a contract nobody keeps. Routebase keeps API design, testing, mocking and documentation on one living source of truth, and this MCP server exposes that workspace to AI agents. Agents can design endpoints, write and run test suites, manage mock servers and publish documentation, always under the permissions of the connected Routebase account.
Turn any public webpage into JSON with AI, save it as a live JSON API, and call it from your agent.
Deterministic JSON checks with signed evidence and x402-paid execution
Discovery registry for AI agents: 660+ APIs, MCP servers and CLIs, each health-checked every 6 hours with real requests — full initialize + tools/list handshakes for MCP, real calls for APIs — plus response-schema validation that catches responses which parse fine but are missing a required field.
Point Gecko at an OpenAPI spec; get first-call-correct, auth-hidden agent tools.
Deploy production REST APIs from JSON schemas in seconds. Manage projects, schemas, and deployments.
Inspect external HTTPS 429/503 retries with server-recorded attempts, Retry-After and arrival times.
Sanctions API docs and request validation, with account-linked synthetic sandbox testing.
Free MCP, API auth, webhook and schema diagnostics with bounded checks and safe quote routing.
Guide developers from setup through a verified, policy-aware, audited Alter API call.
What is known to be broken in an MCP server or API operation, with the check that found it.
Any API, four tools: discover, call with routing and signed receipts, verify, dispute.
