Feature & Specification Comparison

Specification	Calllint calllint Security	Depguard mopanc Security
Summary	Pre-flight security linter for MCP servers, agent tools, and skills. Scans a config before it runs — offline, deterministic, evidence-backed — and returns SAFE / REVIEW / BLOCK / UNKNOWN verdicts without executing the server it judges. CLI (npx calllint scan), MCP server (npx calllint-mcp), SARIF + CI gate. UNKNOWN is never SAFE.	Pre-install guardian for npm packages with static code analysis, supply-chain attack detection, vulnerability audit (npm + GitHub Advisory Database), AI hallucination guard, and CycloneDX 1.6 SBOM generation with VEX. 28 MCP tools. Zero runtime dependencies — the SBOM serializer is implemented natively against the public CycloneDX schema.
