Trentina MCP Server

Trentina is a secure MCP gateway that inspects everything between your AI agents and the outside world - web content, MCP tool responses and tool definitions, Matrix messages, LLM completions, and monitoring alerts - through a three-layer defense pipeline at every ingress, with per-profile enforcement (flag or block) and a full audit trail. Content is never silently modified: what your agent reads is what actually…

People who work with Gemini and Trentina and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
