Overview

What is MCP Guardian?

MCP Guardian is a runtime security, cost governance, and health monitoring proxy for MCP infrastructure. It uses a three‑layer detection engine (regex → schema → LLM), a YAML policy engine with hot‑reload, and provides enterprise observability.

How to use MCP Guardian?

Deploy MCP Guardian as a proxy between MCP clients and servers. Define security and cost policies using YAML files that support hot‑reload. Monitor security events, token costs, and server health through the built‑in web dashboard and Prometheus metrics.
