Sati Grumpy is a Model Context Protocol (MCP) server: MCP commerce surface for refurbished datacenter hardware, with x402 agent-payment discovery. In practice that means any MCP-compatible AI assistant can call Sati Grumpy's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://sati-grumpy.fly.dev/mcp and you're connected, with nothing to install locally. The current release is v1.0.0, published under the MIT license, with source at Fish-Tacos/sati-grumpy-demo on GitHub.
Sati Grumpy is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
