Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Proof-of-behavior enforcement for AI agents. Define behavioral covenant rules (permit/forbid/require), enforce at runtime before execution, get SHA-256 hash-chained tamper-evident audit logs, and verify compliance independently. Cross-agent verification handshake — no proof, no transaction. MIT licensed, 4,244 tests.
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.
