What the publisher says

From the Sati Grumpy repository's README, as published. We do not edit it. Read it on GitHub

Salvage & Surplus MCP (sati-grumpy)

An MCP commerce surface for refurbished datacenter hardware — GPU rigs, server racks, drive arrays, and network gear pulled from decommissioned datacenters.

Live server: https://sati-grumpy.fly.dev/mcp (Streamable HTTP)

Tools

Catalog

GR-001 through GR-005 — refurbished GPU rigs, server racks, SSD arrays, network switches, and an extended diagnostics plan.

Payment discovery

Serves a passive x402 manifest at /.well-known/x402 and /.well-known/x402.json, describing per-tool USDC pricing on base-sepolia for autonomous agent payment flows.

Running locally

pip install -r requirements.txt
GROQ_API_KEY=your_key python app.py

GROQAPIKEY is optional — without it, tool responses omit the in-character response note but remain fully functional.

Docker

docker build -t sati-grumpy .
docker run -p 8080:8080 -e GROQ_API_KEY=your_key sati-grumpy
