UCP Profile Generator

Generate a public UCP discovery profile for a merchant.

Required Inputs

Merchant domain
Business/display name
Payment provider: stripe, shopify, or adyen
Transport: rest or mcp
Capabilities: comma-separated list from checkout,cart,catalog,fulfillment,discount,order

Run

python ${CLAUDE_SKILL_DIR}/scripts/generate_profile.py \
  --domain example.com \
  --name "Example Store" \
  --payment stripe \
  --transport rest \
  --caps checkout,cart,catalog,fulfillment,discount,order \
  --output store/clients/example/ucp-profile.json

Output Contract

The script writes ucp-profile.json with:

ucp.version
ucp.services
ucp.capabilities
ucp.payment_handlers

Some payment templates intentionally contain FILL_IN placeholders for public merchant identifiers or publishable keys. Replace those before deployment.

Deployment

Host the final JSON at:

https://{merchant_domain}/.well-known/ucp

Serve it as JSON and allow public reads. The profile is public discovery data.

Hard Rules

Never include secret API keys in the profile.
Do not infer capabilities that the merchant cannot actually serve.
If FILL_IN remains, report it clearly and do not call the profile final.

Downstream

ucp-checkout uses the profile to design service endpoints.
ucp-validate checks the deployed profile.
