GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Conformance checker for MCP servers. Free, no key, verdicts recomputable and re-measured daily.
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.
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.
Signed, offline-verifiable contract-change authorization. Only a granted change can proceed.
Point Gecko at an OpenAPI spec; get first-call-correct, auth-hidden agent tools.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
Test curl retries locally or inspect remote 429/503 Retry-After traces; optionally share findings.
Guide developers from setup through a verified, policy-aware, audited Alter API call.
Any API, four tools: discover, call with routing and signed receipts, verify, dispute.
