Koskamo

CallLint MCP

A static preflight safety gate for MCP servers that scans configurations before execution to determine blast radius. It provides deterministic, evidence-backed verdicts (SAFE, REVIEW, BLOCK, UNKNOWN) regarding tool authority, filesystem access, network egress, and prompt injection risks without executing the server.
