kerlenton / mcpsnoop
Wireshark for MCP. A transparent proxy between your AI client and MCP server. Watch every call live in your terminal, fail CI on what it finds, export OpenTelemetry spans.
Why this job: name: mcp; says: mcp server; topics: model-context-protocol, mcp
What it does
The official MCP Inspector connects as its own client, so it never sees what *your* client (Cursor, Claude Code, Codex) actually sends your server. And anything that waits for a request to arrive can't show the call the model never made, or made with the wrong arguments. When a tool silently isn't called, capabilities don't line up, or a call just hangs, you're left digging through logs and guessing.
