RoutebaseA

dev.routebase.mcp

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.

What is known to be broken in an MCP server or API operation, with the check that found it.

Webhook URLs for AI agents: receive, wait for, replay, sign and verify webhooks (Stripe, GitHub…).

Free agent-service discovery, OpenAPI document checks, and receipt verification. No API key needed.

Turn any task into the right API calls: discover, evaluate, and integrate public APIs.

Search the JoJ API marketplace, read endpoint docs, and call any API with one key via one gateway.
