For programmatic access, the same data lives in:
data/listings.json— Every listing with full metadatadata/categories.json— Category definitionsdata/schema.json— JSON Schema for validating new entries
Found a UCP tool we're missing? Two ways to add it:
- Open a PR — Follow CONTRIBUTING.md, then add an entry to
data/listings.json - Submit through the site — ucplist.ai/submit
Every new factual listing requires a source, verification date, and evidence status. We review every submission personally. The deferred historical backfill is tracked in TODO.md.
UCP is an open protocol. Its ecosystem directory should be open too. We maintain this data so that:
- Developers can programmatically discover UCP-enabled services
- AI agents can query the registry to find merchants and tools
- The community can submit additions and corrections
- Other projects can build on this data (with attribution)
