Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
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.
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.
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.
Signed, offline-verifiable contract-change authorization. Only a granted change can proceed.
Check x402 endpoints like a paying agent: diagnose, fix plans, pre-payment checks. Free quick check.
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.
What is known to be broken in an MCP server or API operation, with the check that found it.
Free agent tests (no account or payment); paid ping.
Point Claude Code, Qwen Code, Cursor, or any MCP client at https://docs.jmeter.ai/api/mcp and your agent answers JMeter questions grounded in this documentation, with a source link for every answer. Free, no API key, no signup.
Audits a sample of HTTP request URLs against explicit, documented cache-key standardization rules...
Ephemeral mailboxes and a mock OAuth IdP for testing email and auth flows — 39 API-driven tools covering mailboxes, mails, attachments, domains, teams, and mock identities.
