Mcp Observatory
A testing framework for MCP servers that is itself an MCP server. Scans your Claude config to discover all configured servers, checks their capabilities, invokes safe tools to verify they execute, and diffs schemas across runs to catch breaking changes. Records live sessions to cassettes for offline replay in CI, runs security analysis to flag shell injection risks and credential leakage, and generates health scores. Ships with a GitHub Action that comments regression reports on PRs. When you add it to Claude as an MCP server, your agent can autonomously test and monitor your other servers using nine tools including scan, check_server, and verify. Useful for regression testing during MCP server development or watching production deployments for schema drift.
