# Using Claude

# Using Claude with Marrow

Use Claude when you want to query your synced Marrow data from claude.ai, Claude Desktop, or Claude Code.

**Recommended for Claude (web / Desktop):** connect via OAuth from AI Platforms.\
**Claude Code:** use the MCP CLI steps below (listed separately on AI Platforms).

## Prerequisites

* At least one data source connected in [Integrations](../Marrow%20Basics/Features/Integrations.md) and syncing in [Data Explorer](../Marrow%20Basics/Features/Data%20Explorer.md)
* Access to Claude (claude.ai, Claude Desktop, or [Claude Code](https://claude.com/claude-code))
* Permission to add connectors in your Claude workspace (Team/Enterprise often require an Owner)
* For Claude Code MCP: an MCP key from [AI Platforms](../Marrow%20Basics/Features/AI%20Platforms.md)

## Claude (web / Desktop): OAuth (recommended)

1. In Marrow, open **AI Hub → AI Platforms**.
2. Under **Quick connection: OAuth**, select **Claude**.
3. Click **Connect** and complete the authorization steps in Claude.
4. Confirm a session appears under **OAuth sessions**.

If Claude is already connected via OAuth, you do **not** need to add Marrow again via MCP.

## Claude (web / Desktop): custom MCP connector

Use this path if you prefer adding Marrow as a remote MCP connector yourself.

### Step 1: Copy the Marrow MCP URL

From **AI Platforms**, copy:

`https://mcp.marrow.ai/mcp/v1`

### Step 2: Add Marrow as a custom connector

**Pro / Max (individual):**

1. Go to [claude.ai](https://claude.ai).
2. Open **Customize → Connectors** (or **Settings → Connectors**).
3. Select **+** → **Add custom connector**.
4. Set **Name** to `Marrow`.
5. Paste the MCP server URL.
6. Complete any sign-in / approval prompts, then select **Add**.

**Team / Enterprise:**

1. An Owner adds the connector in **Organization settings → Connectors** (Add → Custom → Web) with the same URL.
2. Members then open **Customize → Connectors**, find **Marrow**, and click **Connect**.

### Step 3: Test the connection

Start a new chat and enable the Marrow connector if needed, then ask:

```
Show me my Amazon Seller sales for the last 7 days.
```

## Claude Code: MCP

Claude Code is listed separately on the AI Platforms documentation grid. Use an MCP key for headless / CLI auth.

### Step 1: Get Marrow credentials

* URL: `https://mcp.marrow.ai/mcp/v1`
* Create an **MCP key** on AI Platforms (shown only once)

### Step 2: Add the server

From your project root:

```bash theme={null}
claude mcp add --transport http --scope project \
  --header "Authorization: Bearer YOUR_MCP_KEY" \
  marrow "https://mcp.marrow.ai/mcp/v1"
```

Replace `YOUR_MCP_KEY` with your key.

* `--scope project` writes `.mcp.json` in the project (good for a shared team setup)
* `--scope user` saves the server for your user across projects

### Step 3: Reload and test

In an existing session, run `/mcp` to refresh. Then try:

```
Show me my Amazon Seller sales for the last 7 days.
```

## Troubleshooting

### I don't see Connectors or Add custom connector

* Your Claude plan or workspace permissions may restrict custom connectors.
* On Team/Enterprise, ask an Owner to add Marrow first.

### Sign-in or approval keeps looping

* Allow pop-ups for `claude.ai` and Marrow.
* Retry in a private window to rule out extension issues.

### Auth errors after connecting

* Re-add the connector or reconnect OAuth from AI Platforms.
* For Claude Code, confirm the MCP key is active and not revoked.

## Security

* Marrow is **read-only** and never posts on your behalf.
* Access follows the Marrow user who approved the connection.
* Revoke OAuth sessions or rotate MCP keys from AI Platforms anytime.
