Common questions

Is MCP Ucp safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: UCP_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (0.1.4) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@codespar/mcp-ucp

Deprecated: no live endpoint. Measured on 2026-09-27: commerce.googleapis.com answers every path with Google's generic Error 404 (Not Found) page, and sandbox.commerce.googleapis.com (used with UCP_SANDBOX=true) fails the TLS handshake, because the certificate served there covers *.googleapis.com and not the extra label. UCP is an open specification, not an API Google hosts. No tool in this server reaches a service. The package is deprecated on npm and stays in this repository for reference only. If you have a working endpoint, point the server at it with UCP_BASE_URL. To bring the package back, open an issue in mcp-dev-latam with the provider's documented base URL.

MCP server for Google UCP — Universal Commerce Protocol for agentic shopping, cart, checkout, orders, and delivery

What is UCP?

Universal Commerce Protocol (UCP) is Google's open standard for agentic commerce. It enables AI agents to autonomously discover products, build carts, checkout, manage orders, and track deliveries — without screen-scraping or bespoke merchant integrations.

UCP works alongside AP2 (payment processing) and A2A (agent-to-agent interoperability), with MCP as the transport layer.

Quick Start

Claude Desktop

"mcpServers": { "ucp": { "command": "npx", "args": ["-y", "@codespar/mcp-ucp"], "env": { "UCP_API_KEY": "your-key", "UCP_MERCHANT_ID": "your-merchant-id" } } } }

UCP + AP2 + A2A — The Full Stack

AI Agent

└── MCP (tool interface) └── UCP (commerce: discover → cart → checkout → order → delivery) ├── A2A (agent-to-agent discovery & communication) └── AP2 (payment: authorize → execute → settle)

Environment Variables

Variable	Required	Description
`UCP_API_KEY`	Yes	Sent as `Authorization: Bearer`
`UCP_MERCHANT_ID`	No	Sent as the `X-Merchant-Id` header
`UCP_SANDBOX`	No	`true` switches `BASE_URL` to `https://sandbox.commerce.googleapis.com/ucp/v1`, which fails TLS

Enterprise

Need governance, budget limits, and audit trails for agent payments? CodeSpar Enterprise adds policy engine, payment routing, and compliance templates on top of these MCP servers.

Authentication

The server sends UCP_API_KEY as an Authorization: Bearer header and UCP_MERCHANT_ID as an X-Merchant-Id header on every request (src/index.ts:78-83).

There is no portal issuing those credentials. The developer portal this README used to link, developers.google.com/agents/commerce, answers HTTP 404.
