Conformance checker for MCP servers. Free, no key, verdicts recomputable and re-measured daily.
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.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
Check whether an MCP server answers, what its tools claim, and whether that claim has changed.
