# key-guard A local MCP server that keeps API keys off Claude's servers. ## Why This Exists When Claude reads a file containing an API key, the raw key content gets sent to Claude's servers. key-guard prevents this by acting as a local middleman — Claude calls a tool, the tool reads the key and makes the API call locally, and only the result is returned to Claude. — AI Agent Skill | Install, Stats & Docs | ClawHub Skills Lib
