# ChatGPT connector

> Connect Crustdata to ChatGPT as a custom MCP connector: 800M+ people profiles and 200M+ companies in chat, with a browser sign-in and no API key to paste.

ChatGPT reaches Crustdata through the same [MCP server](/for-agents/mcp) as every other client. Crustdata is not in the OpenAI directory yet, so you add it as a custom connector.

<Note>
  OpenAI has not reviewed the Crustdata server, so ChatGPT asks you to turn on **Developer mode** first. On a team plan, an admin may need to approve the connector. See [Approval on team plans](#approval-on-team-plans).
</Note>

The endpoint is the same everywhere:

<div style={{ marginLeft: '4px', marginRight: '4px' }}>
  ```
  https://install.crustdata.com/mcp
  ```
</div>

* **One URL to add.** No SDK, no local process, no config file.
* **Browser sign-in.** No API key to paste into a chat.
* **The same tools everywhere.** The data tools you already have in Claude, Cursor, and the CLI.

## Before you start

* A Crustdata account. [Sign in or create one](https://app.crustdata.com/auth/login).

## Turn on developer mode

<Steps>
  <Step title="Open your security settings">
    In ChatGPT, open **Settings**, then **Security and login**.
  </Step>

  <Step title="Turn on Developer mode">
    Scroll to **Developer mode** and turn it on.
  </Step>
</Steps>

## Add the connector

<Steps>
  <Step title="Open the plugin directory">
    Go to [chatgpt.com/plugins](https://chatgpt.com/plugins), or click **Plugins** in the ChatGPT sidebar. Some versions label this section **Connectors**.
  </Step>

  <Step title="Start a new connector">
    Click the **+** button next to the search box to open the **New Plugin** dialog.
  </Step>

  <Step title="Fill in the connection">
    * **Name:** Crustdata
    * **Connection:** Server URL
    * **Server URL:** `https://install.crustdata.com/mcp`
    * **Authentication:** OAuth
  </Step>

  <Step title="Confirm and create">
    Select **I understand and want to continue**, then click **Create**.
  </Step>

  <Step title="Connect">
    Open the connector, click **Connect** on the **Connection** row, then sign in.
  </Step>
</Steps>

The connector then shows a **Review status** of `development`, which is normal for one you added yourself.

## Approval on team plans

<Warning>
  Team plans only: ChatGPT Business, Enterprise, and Edu. Crustdata is not verified in the OpenAI directory, so a workspace admin may need to allow developer mode or approve the connector.

  If **Developer mode** is missing or the connector will not save, ask your admin to allow it, then add it again. Personal plans have no approval step.
</Warning>

## Check it worked

Ask ChatGPT:

> How many Crustdata credits should I have?

A number means you are connected.

The connector lists three tools, `execute`, `list_tools`, and `get_schema`, rather than one per data type. That is expected.

If you get no number:

* Check the **Connection** row. If it still reads **Connect**, the sign-in did not finish.
* Start a new chat. A connector added mid-conversation may not be picked up until you do.
* Confirm **Lockdown mode** is off.

## Try it

Ask for what you want in plain English:

* "Show me AI startups with 100-500 employees"
* "Who are the engineering leaders at Anthropic?"
* "What jobs does Stripe have open right now?"
* "Find the profile for `jane.doe@acme.com`"

A single request can chain steps: "Find AI startups hiring engineers, then get me the founders' emails."
