# Connecting

> Add the GC AI MCP server to ChatGPT, Claude, Cursor, or any MCP client, and sign in with your GC AI account.

<Note>
  The MCP server is in public beta. It is open to use and still being refined, so tools and behavior may change.
</Note>

The GC AI MCP server lives at one endpoint:

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

You do not need an API key. The server authenticates with your GC AI login through a standard OAuth flow: when you add it, your host opens a GC AI sign-in page, you approve access, and the host stores the connection. Every request then runs as you.

## Before you connect

Two things need to be true for the connection to work:

1. **You have a GC AI account.** The assistant acts as you, so you sign in with your own credentials.
2. **Your organization has the MCP server turned on.** It is off by default. An org admin turns it on under **Settings**, **API**.

If your organization has not turned MCP on yet, you can still add the server and sign in. The tools appear in your host, and calling any of them returns a message telling you to ask your admin. Once the admin turns it on, the same tools start working with no need to reconnect.

## Add the server to your host

The steps differ slightly by host, but the shape is the same everywhere: point the host at the endpoint above, then complete the GC AI sign-in when prompted.

<Tabs>
  <Tab title="ChatGPT">
    In a ChatGPT plan that supports connectors, add a new connector using the URL `https://app.gc.ai/api/mcp`. ChatGPT walks you through the GC AI sign-in, then lists the GC AI tools. Enable the ones you want the assistant to use.
  </Tab>

  <Tab title="Claude">
    In Claude, add GC AI from the connectors directory.

    <Steps>
      <Step title="Open Customize">
        In the Claude sidebar, click **Customize**.

      <Step title="Open Connectors">
        Under **Customize**, select **Connectors**.

        Click **Add**, then **Browse connectors**.

      <Step title="Add GC AI">
        Search for **GC AI** and add it.

      </Step>
    </Steps>

    Approve the GC AI sign-in when Claude opens it, and the tools become available in your conversations. To connect manually instead, add a custom connector pointing at `https://app.gc.ai/api/mcp`.
  </Tab>

  <Tab title="Cursor">
    Add the server to your MCP configuration with the same URL. Cursor opens the GC AI sign-in on first use, then the tools are available to the agent.

    ```json theme={null}
    {
      "mcpServers": {
        "gc-ai": {
          "url": "https://app.gc.ai/api/mcp"
        }
      }
    }
    ```
  </Tab>

  <Tab title="Other clients">
    Any MCP client that supports remote servers over HTTP with OAuth can connect. Use the endpoint `https://app.gc.ai/api/mcp`; the client discovers the sign-in flow automatically from the server's OAuth metadata.
  </Tab>
</Tabs>

<Note>
  The exact menu labels vary by host and change over time. If you do not see a place to add a remote MCP server or connector, check that your plan supports custom connectors.
</Note>

## Verify the connection

Once connected, ask the assistant to run a quick read, for example: "List my GC AI projects." That calls `get_projects` and confirms the tools are wired up and scoped to your account. From there the assistant can upload files, run playbooks, and ask questions grounded in your knowledge base.
