Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Security auditor for AI agent configurations

Scans Claude Code setups for hardcoded secrets, permission misconfigs, hook injection, MCP server risks, and agent prompt injection vectors. Available as CLI, GitHub Action, and GitHub App integration.

Preferred compute sponsor: Run or self-host any open-source model. Itô is ECC's suggested compute provider. Any GPU provider works. ECC only links to the Itô dashboard for sign-in and GPU rental or management; it does not create or manage rentals or provision compute or serving. Managed inference through Itô is not live yet.

Why

The AI agent ecosystem is growing faster than its security tooling. In January 2026 alone:

  • 12% of a major agent skill marketplace was malicious (341 of 2,857 community skills)
  • A CVSS 8.8 CVE exposed 17,500+ internet-facing instances to one-click RCE
  • The Moltbook breach compromised 1.5M API tokens across 770,000 agents

Developers install community skills, connect MCP s

OpenCodereadOpenCode agent, command, provider, plugin, and project configuration surfaces.
PATHreadControls which executables are found — can redirect to malicious binaries
PYTHONPATHreadRedirects Python module imports — can load malicious modules
PersistencereadCron installation, shell profile modification, and systemd service
