GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
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.
Webhook, email, WebSocket and tunnel testing for AI agents: capture, wait, verify, replay.
Remote MCP that evaluates one public HTTPS URL for WebMCP readiness: intent, tools observed, what to add, what never to expose.
Agent Observatory: checks A2A, MCP and OpenAPI declarations and logs published changes.
A webhook inbox for agents: one call returns a live URL. Mock, verify, inspect and replay.
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.

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.
Independent health, price and history for x402/MPP endpoints. Metered over x402; free grade on web.
Detect breaking changes, generate changelogs, diff, and validate OpenAPI specs.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
Point Gecko at an OpenAPI spec; get first-call-correct, auth-hidden agent tools.
Any API, four tools: discover, call with routing and signed receipts, verify, dispute.
What is known to be broken in an MCP server or API operation, with the check that found it.
