# Claude

> Connect Terrapin to Claude and Claude Code.

The Terrapin connector gives Claude read-only access to [Terrapin's data](https://docs.terrapinfinance.com/mcp/introduction.md#what-the-tools-cover). It can't change anything in your Terrapin account, and Terrapin receives the tool calls Claude makes, not your conversation.

## Before you start

You need a Terrapin account with [API access](https://docs.terrapinfinance.com/mcp/introduction.md#access-and-quotas).

On Claude Team and Enterprise, an Owner first adds the connector for the organization: in **Organization settings → Connectors**, click **Browse connectors**, select **Terrapin** and click **Add to your team**. Until then, a Team member sees **Request** on Terrapin, which asks the Owners to add it. Each member then connects with their own Terrapin account.

## Connect in Claude

**1. Find Terrapin in the directory**

In [claude.ai](https://claude.ai) or Claude Desktop, open **Customize → Connectors**, click the **+** next to **Connectors**, and search for **Terrapin**.

**2. Connect**

Click **Connect**. Claude opens Terrapin's sign-in page.

**3. Sign in to Terrapin**

Enter your email and the 6-digit PIN code we email you. If you're already signed in, Terrapin skips this step.

**4. Choose the organization and approve**

Pick the organization whose plan and quotas Claude should use, and click **Approve**. You're back in Claude, with Terrapin under your connectors.

**5. Use it in a chat**

Click the **+** in the lower left of the chat, hover over **Connectors** and check that **Terrapin** is on. Then ask a question, such as one of the [example prompts](https://docs.terrapinfinance.com/mcp/introduction.md#example-prompts).

## Connect in Claude Code

If you sign in to Claude Code with your Claude account, the connectors you connected in Claude are already there, Terrapin included. Otherwise, add the server:

```bash theme={"theme":{"light":"catppuccin-latte","dark":"github-dark-high-contrast"}}
claude mcp add --transport http terrapin https://terrapinfinance.com/mcp
```

Add `--scope user` to use it in every project, not only the current one. Then run `/mcp` in a Claude Code session, select **terrapin** and choose **Authenticate**. Terrapin opens in your browser: sign in, pick the organization and click **Approve**.

The approval page names claude.ai rather than Claude Code, and warns that it returns you to an app on your computer, which any app there could pose as. Approve only if you started the sign-in yourself.

## Troubleshooting

For errors that aren't specific to Claude, see [Troubleshooting](https://docs.terrapinfinance.com/mcp/introduction.md#troubleshooting) in MCP access.

### Claude can't read a document

To fetch the link `download_document` returns, Claude needs code execution, or in Claude Code a terminal, that's allowed to reach `terrapinfinance.com`, as [Network access](https://docs.terrapinfinance.com/mcp/network-access.md) describes.
