Inside Geiger: The Zero-Dependency Scanner Auditing the AI Agent Ecosystem

Geiger, a zero-dependency, read-only scanner, has been released to audit the AI agent ecosystem by inventorying AI harnesses, exposed credentials, and filesystem capabilities without telemetry or runtime binary execution. The tool restores empirical visibility to an unmonitored attack surface as autonomous agents and Model Context Protocol servers proliferate across developer workstations.

As autonomous software agents and Model Context Protocol servers silently proliferate across developer workstations, tracking local permissions has become an urgent security imperative. Geiger delivers a zero-dependency, read-only scanner that inventories AI harnesses, exposed credentials, and filesystem capabilities without telemetry or runtime binary execution. By inspecting static configuration trees and parsing capability metadata, it restores empirical visibility to an unmonitored attack surface.
