Why it matters
Geiger gives defenders visibility into the sprawling and often unmonitored attack surface of AI agents and MCP servers installed on a machine, helping detect unauthorized or risky AI extensions and configuration drift.
Geiger is a read-only command-line scanner that inventories AI agents, MCP servers, plugins, hooks, skills, and AI extensions across tools like Claude Code, Claude Desktop, Cursor, Windsurf, VS Code, Codex, Gemini, Aider, and browser profiles. It provides plain-language exposure labels, origin tracing, policy-wrapper recognition, and a diff mode for drift detection against a saved baseline.
