peckish-mcp 🍜

Let Claude order your dinner. An MCP server that gives Claude Desktop or Claude Code real DoorDash ordering — it searches, compares actual fee-included totals, builds the cart, and hands the final "place this order?" decision back to you as a native approval dialog.

No API key needed: your Claude subscription powers the model.

      No mushrooms, and don't bleed me on fees.

Install

claude mcp add peckish -- npx -y peckish-mcp

Or in ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "peckish": {
      "command": "npx",
      "args": ["-y", "peckish-mcp"]
    }
  }
}

Claude Desktop users can also install the double-click .mcpb extension.

Requirements

• A Mac with Apple Silicon — Peckish is local-first; your machine is the backend, because DoorDash sign-in lives in your keychain.
• Node.js 20+
• DoorDash CLI access (currently waitlist-gated by DoorDash). Install dd-cli, verify the published SHA256, run bash install.sh, then dd-cli login.

Set DD_CLI_PATH if dd-cli isn't at ~/.local/bin/dd-cli — GUI apps don't inherit your shell PATH.

Safety model

Placing an order always requires an explicit approval rendered by your MCP client, not by the model:

• submit_order opens a client elicitation dialog you must approve. Clients that don't support elicitation cannot place orders at all (fail closed) — they can still browse, compare, and build carts.
• The model must show you the itemized quote, confirm the Dasher tip, and name the card being charged before it may even ask.
• Order submission never auto-retries (it isn't idempotent); success is reported only after order status confirms it.
• Merchant text is treated as data — widget and assistant-instruction fields are stripped so store content can't steer the model.
• Every tool call, argument set, and confirmation outcome is written to ~/.peckish/logs/*.jsonl.

What it can do

28 tools covering search → menus → carts → preview → confirm → submit, plus comparison shopping across up to 3 finalists with true totals, promo scanning, pickup-vs-delivery comparison, order history and honest spend breakdowns, reorders with silent-drop detection, saved dietary preferences, work benefits (company budgets, expense codes), scheduled delivery, and groceries/retail/pets/alcohol.

Other surfaces

peckish-mcp is one of three surfaces over the same tool layer. The peckish package adds a terminal chat REPL and a local web app (both use your own ANTHROPIC_API_KEY), and there's a double-clickable Mac app.
