# Connect Outbind over MCP

> Add Outbind's MCP server to Claude, ChatGPT, Claude Code, Cursor, VS Code or another app, sign in with OAuth and pick what it may do.

Outbind's MCP server is at:

```
https://app.outbind.ai/api/mcp
```

It uses Streamable HTTP and OAuth 2.1 sign-in. Apps register themselves, so leave any "OAuth Client ID" or "Client secret" fields empty. The person needs an Outbind account first: see [Create an account](https://outbind.ai/docs/sign-up).

When the person presses Connect, Outbind opens in the browser. They sign in, pick what the app may do and press **Allow**:

- **Read only**: read the brain, recall prospects, sort replies.
- **Can draft and edit**: everything above, plus every writing tool, prospect memory, lessons, documents and the email checker. **Pick this one** for the brain.

They can disconnect any app at any time in [Settings, MCP](https://app.outbind.ai/settings/mcp), which ends its access at once.

## Claude (web and desktop)

1. Open **Settings**, then **Connectors**, and press **Add custom connector**. On a Team or Enterprise plan, an owner adds it once under Organization settings, Connectors.
2. Name it `Outbind` and paste `https://app.outbind.ai/api/mcp`. Leave the advanced OAuth fields empty.
3. Press **Add**, then **Connect**. Sign in to Outbind, pick **Can draft and edit** and press **Allow**.
4. In a chat, turn Outbind on in the tools menu and ask, for example: "Write a first email to jane@acme.com."

## ChatGPT

1. Open **Settings**, then **Apps & Connectors**, then **Advanced settings**, and turn on **Developer mode**. On a Business or Enterprise plan, an admin may need to allow it first.
2. Back in Apps & Connectors, press **Create**. Name it `Outbind`, paste `https://app.outbind.ai/api/mcp` and pick **OAuth** for authentication.
3. Press **Create**, sign in to Outbind, pick **Can draft and edit** and press **Allow**.
4. In a chat, add Outbind from the **+** menu.

## Claude Code

```
claude mcp add --transport http outbind https://app.outbind.ai/api/mcp
```

Then start Claude Code, type `/mcp`, pick `outbind` and choose **Authenticate**. Sign in, pick **Can draft and edit** and press **Allow**.

## Cursor

Open **Cursor Settings**, then **Tools & MCP**, press **New MCP server** and add this to `mcp.json`:

```json
{
  "mcpServers": {
    "outbind": { "url": "https://app.outbind.ai/api/mcp" }
  }
}
```

Next to `outbind`, press **Connect** (it may say Needs login), then sign in and press **Allow**.

## VS Code

Add this to `.vscode/mcp.json` (or run **MCP: Add Server**, pick HTTP and paste the URL):

```json
{
  "servers": {
    "outbind": { "type": "http", "url": "https://app.outbind.ai/api/mcp" }
  }
}
```

Press **Start** above the `outbind` entry and allow the sign-in.

## Other apps

If the app can sign in to MCP servers with OAuth, give it the server URL; it finds Outbind's sign-in by itself (the server answers `401` with a `WWW-Authenticate` header pointing at its OAuth metadata).

If it only takes a key: in [Settings, MCP](https://app.outbind.ai/settings/mcp) open **Use a key instead**, make an **AI assistant, can draft and edit** key (it is shown once) and send it on every request:

```
Authorization: Bearer ob_your_key
```

Keys go in the header only, never in a URL. A key acts as the person who made it, with their current role, and stops working when it's revoked or they leave the workspace.
