Overview

About MCP Fuzz

mcp-fuzz is a stdlib-only Python robustness harness for AAIF that throws 17 malformed and adversarial JSON-RPC cases at an MCP server over stdio and grades it A to F on crash resistance, responsiveness, error correctness, and envelope hygiene, with a liveness probe after every case so any crash or hang is caught.

Tools

No tool list yet. Remote servers get one after the first health check.
