# Integrations overview

> Use the hosted connection widget or the authenticated MCP endpoint.

Polymorfa documents two customer integrations that are available
through the API itself.

<Columns cols={2}>
  <Card title="Connect widget" icon="window" href="/integrations/widget">
    Create a short-lived hosted flow that lets a customer connect a number
    without exposing your organization key.
  </Card>

  <Card title="MCP server" icon="robot" href="/integrations/mcp-server">
    Connect an MCP client to the authenticated Polymorfa tool surface.
  </Card>
</Columns>

## Choose an integration

| Goal                                                 | Integration                            |
| ---------------------------------------------------- | -------------------------------------- |
| Let customers connect a number from your application | [Connect widget](/integrations/widget) |
| Let an MCP client call supported Polymorfa tools     | [MCP server](/integrations/mcp-server) |

Both integrations use the same credential and authorization boundaries as
their underlying API operations. Keep organization and project credentials on
trusted servers, and use short-lived client tokens only for the browser or
mobile actions they explicitly allow.
