Overview

AI-generated overview

Remote MCP storefront for refurbished datacenter hardware: search a catalog, add items to a cart, and complete a purchase.

What you can do
  • Search the Salvage & Surplus catalog and filter by category (compute, servers, storage, networking, support)
  • Fetch full details for a single product by SKU
  • Add a product to a cart and receive a cart token
  • Start checkout with a cart token and billing email to get a payment token
  • Confirm payment with a payment token and credit card token to place the order
When to use it
Useful when an assistant needs to browse or buy refurbished GPU rigs, server racks, drive arrays or network gear from this specific storefront, including agent-driven purchasing flows.
Requirements
A remote Streamable HTTP endpoint; no package install or credentials are declared for connecting. Purchases need a billing email and a credit card token. Running it locally instead requires Python with requirements installed and an optional GROQ_API_KEY.
Before you install
The tools place real orders and take payment: checkout and confirm_payment complete a purchase using a credit card token, so spending can occur. The README also describes per-tool USDC pricing on base-sepolia for autonomous agent payments. Billing email and payment tokens are sent to the remote server.

Installation

In SourceWeft

  1. Open Sati Grumpy in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Fish-Tacos%2Fsati-grumpy/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
