Summary

This PR adds the Universal Commerce Protocol (UCP) MCP server to the community servers list.

What is UCP?

The Universal Commerce Protocol is an open standard for interoperability between commerce entities (merchants, payment handlers, platforms).

What does this MCP server do?

The UCP MCP server provides AI assistants with:

  • Schema access: List and retrieve all UCP JSON schemas (checkout, payment, fulfillment, etc.)
  • API specs: Get OpenAPI and OpenRPC specifications for UCP services
  • Validation: Validate JSON data against UCP schemas
  • Discovery: Query merchant /.well-known/ucp discovery profiles
  • Sample generation: Generate sample checkout requests for testing

Links

Testing

The server has been tested locally and all tools function correctly.

Hi @sakinaroufid! Thanks for this, but we're not accepting unsolicited PRs for new reference servers at this time. Reference servers are created by the maintainers for the purpose of demonstrating and testing MCP specification features. Ongoing maintenance of the reference servers is an burden that we have to consider. Keeping them up to date with the SDK they are implemented in, responding to security issues, etc.
