# ChatGPT

> Connect Nimt to ChatGPT on the web using your Nimt account.

Use Nimt inside a ChatGPT conversation to find projects and read their context.
You do not need Codex, a terminal, or an API key.

<Warning>
  Nimt MCP is in pre-release. Follow this guide only after Nimt has confirmed
  access for you. This guide uses a custom connection, not a public Nimt
  directory listing.
</Warning>

## Before you start

* Sign in to ChatGPT **on the web** and to the Nimt account you want to connect.
* OpenAI currently lists developer mode for Plus, Pro, Business, Enterprise,
  and Education accounts. Free accounts are not listed as eligible.
* For a managed workspace, your administrator may need to enable or publish
  custom connections. Ask them if the relevant controls are missing.

OpenAI changes labels and availability over time. The steps below use the
current **Plugins** and **Security and login** interface; some accounts may still
show **Apps** or **Connectors**. See
[OpenAI's developer mode guide](https://developers.openai.com/api/docs/guides/developer-mode)
for current requirements. ChatGPT's plan is separate from your Nimt account.

## Add Nimt

<Steps>
  <Step title="Enable custom connections">
    Open ChatGPT's **Settings → Security and login** and enable **Developer
    mode**. Read the warning: this permits unverified connections, so only add
    servers you trust. Do not disable other security controls to connect Nimt.

    </Frame>
  </Step>

  <Step title="Create the connection">
    Open [Plugins](https://chatgpt.com/plugins), choose the **+** action to
    create a developer-mode connection, and use these details:

    | Setting        | Value                     |
    | -------------- | ------------------------- |
    | Name           | `Nimt`                    |
    | MCP server URL | `https://api.nimt.ai/mcp` |
    | Authentication | OAuth                     |

    Let ChatGPT discover the OAuth configuration. Nimt supports client metadata
    documents and dynamic registration; you do not need to create or paste an
    OAuth client secret. Do not select **No authentication** for Nimt.
  </Step>

  <Step title="Sign in and choose a workspace">
    Follow the Nimt sign-in flow. Review the requesting application, choose the
    workspace you want ChatGPT to access, and read the requested permissions.
    Choose **Allow access** only if they match your intent, then return to ChatGPT.

    The approval stays tied to this workspace even if you switch workspaces in
    the Nimt app later.
  </Step>

  <Step title="Enable Nimt in a conversation">
    Open a new conversation. Use the **+** menu, choose **Developer mode**, and
    select **Nimt**. A saved connection may appear under **Drafts** until it is
    published within a managed workspace.
  </Step>
</Steps>

## Ask your first question

> Use Nimt to list the projects in my connected workspace.

Choose a returned project, then ask:

> Use Nimt to show this project's tracked models, active prompt count, and
> available data range.

Check ChatGPT's tool activity to confirm it used Nimt. The current actions are
**Workspace list projects** and **Project get metadata**. Both read data; neither
changes your project. See [example questions](/mcp/examples) for more ideas.

## Refresh or disconnect

Open Nimt in ChatGPT's installed plugin settings. Use **Refresh** if its tool
list is outdated, then start a new conversation and select Nimt again.

To revoke Nimt access, open [Connected apps](https://app.nimt.ai/connected-apps)
in Nimt and disconnect the ChatGPT approval for the relevant workspace. Removing
Nimt from a conversation does not revoke its credentials or delete data already
shared with ChatGPT. See [OAuth access](/mcp/authentication/oauth).

## If something goes wrong

* **No create or developer-mode option:** check your ChatGPT plan, account,
  workspace policy, and whether you are using the web interface.
* **Cannot fetch tools:** confirm the exact server URL and complete OAuth.
  Refresh the connection after signing in.
* **ChatGPT answers without Nimt:** select Nimt for the conversation and explicitly
  say “Use Nimt.” It cannot answer report or citation questions through tools
  that are not available yet.
* **Wrong projects:** the approval is bound to one workspace. Reauthorize for
  the intended workspace; changing the active workspace in Nimt is not enough.

For other errors, use [troubleshooting](/mcp/troubleshooting). Review
[authentication and access](/mcp/authentication/overview) before sharing workspace
data with an AI service.
