Openstatus MCP Health Checker

This tool goes beyond basic HTTP pings to provide a comprehensive protocol-level health check for MCP servers, simulating actual client interactions. Key features include: * **Full Handshake:** Executes the complete spec-defined initialize, ping, and tools/list sequence. * **Deep Visibility:** Allows inspection of exact JSON-RPC payloads and negotiated protocol versions. * **Smart Authentication:** Parses RFC 9728 headers on 401 errors to clearly identify token requirements. Unlike simple status checks, this platform performs a true protocol-level verification. It ensures that an MCP endpoint behaves precisely as an actual client expects upon connection. This involves speaking JSON-RPC, completing the full handshake, and confirming the server correctly exposes its promised tools. Users can paste their MCP server URL, add any necessary authorization headers, and run the check to assess server readiness. The system sends JSON-RPC `initialize`, `ping`, and `tools/list` calls in the exact order a client would. Each step can be inspected in detail, providing per-step latency, negotiated protocol version, server information, and session ID. This deep analysis helps identify issues such as server unreachability, incorrect content types, missing JSON-RPC methods, or unmet authentication demands. Ideal for developers and engineering teams managing Model Context Protocol servers, this tool ensures servers are configured correctly and ready to serve various clients. It's perfect for validating new deployments, troubleshooting connectivity issues, and ensuring seamless operation with clients.
