Mettle Mcp is a Model Context Protocol (MCP) server: Experimental machine-oriented challenges and signed results. Does not verify identity or substrate. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It runs locally: the Python package mettle-verifier (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.4.8, published under the Apache-2.0 license, with source at Creed-Space/METTLE on GitHub.
You'll find Mettle Mcp in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
