System Documentation

What problem does it solve?

Diagnose MCP servers failing to register tools or return errors by guiding through handshake validation, env-var injection, tool-schema inspection, and host-side debugging to localize the fault.

Core Features & Use Cases

  • Handshake validation and diagnostic steps for the MCP initialize flow.
  • Tools-list inspection and schema mismatch detection to identify registration issues.
  • Environment-variable propagation checks and host-side debugging to isolate failures across server, transport, and host routing.

Quick Start

Execute the diagnostic workflow against your MCP server to surface actionable clues and recommended fixes.
