Quick Install

Copy the config for your editor. Some servers may need additional setup — check the README.

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "mcp-fuzz": {
      "command": "uvx",
      "args": [
        "mcp-fuzz"
      ]
    }
  }
}

Or install with pip: pip install mcp-fuzz

README Excerpt

Runtime behavioral testing for [MCP](https://modelcontextprotocol.io) servers. Static analysis can't see any of that. Only running the code can. ```bash pip install mcp-runtime-check ``` (The PyPI *distribution* name is `mcp-runtime-check` — `mcp-fuzz` and close variants were blocked by PyPI's anti-typosquat check as too similar to existing packages, same naming friction mcp-doctor hit. The installed CLI command is still `mcp-fuzz`, and the repo/import package are unchanged.)
