Geiger - See every AI agent on your machine and what it can touch

Show HN: Geiger – See every AI agent on your machine and what it can touch

Geiger is a read-only, zero-dependency command-line tool that inventories every AI agent, MCP server, plugin, and AI extension on your machine. It scans known config locations across major ecosystems like Claude Code, VS Code, Cursor, and browser extensions, then labels each finding with exposure levels such as EXECUTES or HOLDS-SECRETS, plus origin and evidence paths. Run it with a single `npx geiger-scan` command—no install, no account, no telemetry. It also supports HTML/JSON reports, strict mode for CI, and drift detection against baselines, making it ideal for developers, IT teams, and security-conscious users who want to know what's really running and what it can reach.
