About This MCP Server
Defenter is a semantic policy broker for AI coding agents. It adds an intelligent security layer inside your IDE that:
Traditional security tools cannot see what an agent is about to share or execute. They look at apps and destinations, not at the intent and content of an agent’s actions.
Defenter bridges this gap by:
This repository contains the Defenter proxy and related components that secure MCP and coding agent traffic.
Defenter is built as a Python based proxy and local middleware that the IDE extension uses to enforce policy. At a high level:
Together, these pieces let you harness AI coding agents and MCP tools without compromising the security of your code, data, or workflows.
