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 and syncing in Data Explorer
  • Access to Claude (claude.ai, Claude Desktop, or 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

​
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.
  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:

​
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:
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:

​
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.
