A missing built-in integration never blocks you: Quaso can call any HTTP API or MCP server, public or internal.

## Register an MCP server

<Steps>
  <Step title="Add the server">
    Under **Settings → MCP servers**, paste the URL of a Streamable-HTTP MCP server (like Supabase).
  </Step>

  <Step title="Authenticate">
    Add a bearer token or header if it needs one. Tokens are encrypted at rest and never shown to the model.
  </Step>

  <Step title="Test connection">
    Hit **Test connection** to see the tools it exposes. From then on the agent can call them in chat.
  </Step>
</Steps>

## HTTP APIs and webhooks

Describe the API and hand Quaso the credentials; it calls the endpoints directly. Automations can also receive **incoming webhooks** at a URL Quaso gives you.

## Try it

Every card opens the Quaso composer with the prompt filled in.
