Connect an AI client

Point ChatGPT, Claude or Cursor at Paywalla

Your AI client can check that your organization is ready and create a published group checkout on your behalf — after you confirm. Copy the server URL below and follow the steps for your client.

MCP server URL
https://paywalla.co/api/mcp

This URL is live once Paywalla’s MCP server is published. Each AI client acts as you — it can only see and create checkouts for the organization you own.

Connect Claude

  1. 1Open the profile menu in the Claude desktop or web app.
  2. 2Go to Settings → Connectors.
  3. 3Click “Add custom connector”, name it (e.g. Paywalla), and paste the MCP server URL above.
  4. 4Click Add. Claude will open Paywalla’s consent page — sign in with your Paywalla account and approve.
You approve every connection

The first time a client connects, it opens Paywalla’s consent page. You sign in with your own Paywalla account and approve the tools it will use. The connection is scoped and revocable — your organization’s API key is never shared with the AI client.

Staying in control
  • Read the preview before you confirm. Creating a checkout emails the organizer and every participant immediately. Your confirmation is the only gate — check the organization, total, deadline and participant list carefully.
  • Watch for prompt injection. If you paste an email, invoice or web page and ask the assistant to build a checkout from it, verify the amount, organization and emails it parsed before confirming — hidden text can't move money, but it can fill the wrong fields.
  • A connection covers every organization you own. Unlike an API key (one per org), an MCP connection acts as your account. If you own several organizations the assistant asks you to choose for each checkout — and you can revoke the whole connection here anytime.

After Paywalla ships changes, refresh the connector in your AI client — assistants cache the tool list. Changing the exposed tools may require you to authorize the client again.
