Phantom Secrets MCP

Phantom Secrets is a local proxy and MCP server that prevents AI coding agents from leaking API keys by replacing real secrets with scoped phm_ placeholders. It allows agents to perform value-blind inventory, diagnostics, and governed requests through an authenticated local proxy, supporting tools like Claude Code, Cursor, Windsurf, and Codex.
