# ChatGPT

> Connect ChatGPT to the Poix MCP server

ChatGPT connects to remote MCP servers through **Developer mode → Connectors**, authorized over OAuth. There's no field to enter a static bearer token — sign-in happens in the browser.

<Steps>
  <Step title="Enable Developer mode">
    In ChatGPT, go to **Settings → Connectors → Advanced → Developer mode** and turn it on.
  </Step>

  <Step title="Add Poix as a connector">
    Under **Connectors**, add a custom connector with the URL `https://mcp.poix.io`.
  </Step>

  <Step title="Sign in and approve">
    ChatGPT opens `https://app.poix.io` in your browser. Sign in with Google or GitHub, then approve the consent screen. If you don't already have a Poix account, signing in creates one automatically, and ChatGPT receives its token without any further steps.

    <Warning>
      A new account starts with no balance, and Poix needs credits for the connection itself, not just for tool calls. Add credits at [app.poix.io/settings/billing](https://app.poix.io/settings/billing) right after signing in, before doing anything else here.
    </Warning>
  </Step>

  <Step title="Verify the connection">
    Back in ChatGPT, the Poix connector should show as connected with tools listed. If it won't connect or lists no tools, the most likely cause on a new account is missing credits, not a broken sign-in — check [app.poix.io/settings/billing](https://app.poix.io/settings/billing).
  </Step>
</Steps>

See [Authentication](/mcp/authentication) for how OAuth sign-in works and how to manage or revoke connected apps under **Connected apps**.
