MCP Security Proxy

Example Use Cases

• 1

  Securely mediate and validate MCP tool requests to prevent attacks.

• 2

  A transparent proxy compatible with any standard MCP server.

• 3

  An ensemble-based anomaly detection system with fail-safe blocking.

Description

This project implements a transparent security proxy for the Model Context Protocol (MCP) that validates all requests between language models and MCP tools using a binary classification system. It employs an ensemble of detectors including rule-based, statistical, semantic, and optional meta-learning models to robustly detect attacks such as injections and anomalies. The proxy ensures MCP protocol compliance while providing fail-safe, margin-based classification to minimize false negatives and enhance security.
