# Add MCP

Connect Twinr's MCP server to Base44 so its AI can read your apps and Twinr's integration guides.

Connecting Twinr's MCP server lets Base44's AI see your real Twinr apps and read Twinr's integration guides, rather than guessing at how Twinr works.

{% hint style="info" %}
Custom MCP connections need a **Builder plan or higher** on Base44. Each account can connect up to 20 servers.
{% endhint %}

## Connect the server

1. Click your **workspace name** at the bottom left.
2. Click **Account preferences**.
3. Click **Builder**, then scroll to **MCP Connections**.
4. Click **Add custom MCP**.
5. Fill in the form:
   * **Name** — `Twinr`, so collaborators recognise it.
   * **URL** — the Twinr MCP server address:

```
https://mcp.twinr.dev/mcp
```

* **Authentication** — choose **OAuth**.
* **Custom headers** — leave empty. Twinr does not need any.

6. Click **Test** to confirm Base44 can reach the server.
7. Click **Test & add** to save it to your account.

Base44 then asks you to authorize the connection. Sign in to Twinr, choose which apps to share, and click **Allow**. See [Twinr MCP Server](/mcp/mcp.md) for what the approval screen shows.

## Check it worked

In the AI chat, ask:

> List my Twinr apps.

It should name your apps. If it reports no access, open **My Profile → AI connections** in Twinr and confirm the connection is listed with the apps you expected.

## Where the connection applies

MCP connections are configured per account, not per app, so Twinr is now available in the AI chat for every Base44 app your account can open. You can switch it off with its toggle without deleting the configuration.

{% hint style="info" %}
Ask for features by name — "add Twinr push notifications" — rather than naming a tool. The AI picks the right guide itself.
