Every scanned point with the score it earned and what moved between them.
First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
A minimal Model Context Protocol server for debugging MCP clients. It echoes back everything it receives — tool arguments, session IDs, metadata — so you can inspect exactly what your client is sending.
Uses Streamable HTTP transport (no stdio).
| Tool | Description |
|---|---|
debug_echo | Returns all passed arguments as JSON along with sessionId and _meta |
debug_inspect | Recursively prints the type and structure of any value |
debug_server_info | Returns Node.js version, platform, uptime, memory usage |

claude mcp add --transport http debug-mcp-server http://127.0.0.1:3000/mcpAll requests go to POST /mcp. The session lifecycle follows the MCP Streamable HTTP spec:
