Koskamo

agent-firewall-mcp

Provides deterministic detection of known attack patterns against AI agents, including package installation, untrusted text reading, link following, and money sending. It uses regex and structural tests against public lists like OSV and OFAC to generate reproducible verdicts without LLMs, running locally or via a free shared mirror.
