API Defects is a project that tracks and reports defects in the public description of machine‑callable operations such as OpenAPI documents and MCP servers. It maintains a directory of known issues, including stale host references, mismatched specifications, missing authentication details, and other inconsistencies that can affect API reliability and developer experience. The service provides JSON endpoints summarizing these defects and offers tools for developers to check and improve their API documentation.
