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.
AI-agent admission-control MCP server: validates file edits against Ring 0 syntax + Ring 0.5 structural-cost regression + workspace boundary (path / glob / shell-redirect / symlink). Negative-space framing — emits BLOCK / WARN / PASS verdicts, never coaches the agent.
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.
