This is an open-source developer tool for building UCP integrations. View on GitHub →
ucp-go is a community Go SDK generated from the canonical UCP JSON Schemas. It targets UCP version 2026-04-08 and ships 145 generated model files across five packages, covering the protocol root, common types, shopping, shopping types, and transports.
The SDK includes generated validation methods, required-property presence tracking, unknown-key preservation for open objects, and differential conformance tests against a draft 2020-12 JSON Schema validator. Its consumer module has no runtime dependencies. The project is currently pre-release and does not guarantee API stability.
Why This Matters for UCP
ucp-go gives Go services schema-derived UCP models and validation without adding runtime dependencies.

The best developer tool in this category. TypeScript types are correct and complete. Error messages actually tell you what went wrong.

Solid tool. The test suite coverage is excellent. I found one edge case in the payment token validation that the maintainers fixed within 48 hours.

Integrated in an afternoon. The discovery endpoint just worked. The CLI flags are well-designed — composable, no magic defaults.

Good tool for UCP conformance testing. Runs fast and the output is easy to parse in CI. Would like a JSON output mode — currently only text.
