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.
URL intelligence for AI agents. 13 tools for security signals and data quality: redirect behaviour, brand impersonation detection, domain age, SSL validation, parked detection, URL structural analysis, DNS enrichment.
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.
