Endpoints

MCP runs the program. Sales are still recorded through Stripe or the REST API at /api/track-sale.

Common questions

Is Merchant MCP the same as the sales API?

No. MCP runs the program for one signed-in team. Sales are still recorded through Stripe or the REST API, including /api/track-sale. Most setups use both: MCP to run the program, Stripe or REST to attribute sales.

Do I need an API key for MCP?

No. You connect with OAuth 2.1 and PKCE. After you sign in and click Allow, the client gets a Bearer token scoped to one team. MCP has no unauthenticated access and no anonymous API keys.

Can one connection manage multiple teams?

No. The consent screen picks one team and the token only works for that team. To switch, reconnect and choose a different team.

Where do agents find how to connect?

Start with /llms.txt and /.well-known/mcp.json on uppercut.co, or read the connect guide at /mcp.md. Interactive setup is at app.uppercut.co/agents/mcp.
