Claude Desktop Integration

Connect Rembrandt to Claude Desktop using the Model Context Protocol (MCP) to access your market intelligence data directly within Claude conversations.

What Is MCP?

MCP (Model Context Protocol) allows Claude Desktop to connect to external services like Rembrandt, giving you access to your market intelligence data directly in your conversations with Claude.

Prerequisites

  • A Rembrandt account with completed onboarding

  • Claude Desktop installed on your computer

  • An active organization in your Rembrandt account

Step-by-Step Setup

Step 1: Start the authorization flow

  1. Open Claude Desktop

  2. Go to Settings > Developer

  3. Add a new MCP server with the Rembrandt server URL: https://api.rembrandtagents.com/mcp

  4. Claude Desktop will redirect you to Rembrandt to authorize the connection

Step 2: Authorize the connection

  1. You'll be redirected to the Rembrandt authorization page

  2. Sign in to your Rembrandt account if prompted

  3. Review the permissions being requested

  4. Click Authorize to approve the connection

If this is your first time using Rembrandt, you may need to complete your account setup first (email verification, profile, and organization selection).

Step 3: Configure Claude Desktop

After authorization, you'll receive an authorization code. Add it to your Claude Desktop configuration:

JSON
{
  "mcpServers": {
    "rembrandt": {
      "url": "https://api.rembrandtagents.com/mcp",
      "authorization": "Bearer YOUR_AUTHORIZATION_CODE"
    }
  }
}

Restart Claude Desktop after saving the configuration.

Step 4: Verify the connection

  1. Start a new conversation in Claude Desktop

  2. Ask Claude: "What buying signals do I have?"

  3. If connected correctly, Claude will access your Rembrandt data and respond with results

Using Rembrandt in Claude

Once connected, you can ask Claude questions like:

  • "Show me prospects with recent activity"

  • "Find companies in the Netherlands with job posting signals"

  • "What open opportunities do we have?"

  • "Get buying signals for Acme Corporation"

  • "Which prospects are in the Supply Chain domain?"

  • "Generate an outreach email based on the signals for Acme"

Claude will use the Rembrandt MCP tools to query your data and answer directly. See the MCP Integration Guide for the full list of available tools and example prompts.

Troubleshooting

Authorization failed

  • Make sure you're logged into your Rembrandt account

  • Verify that your account setup is complete (email verified, organization selected, profile completed)

  • Try the authorization flow again

Claude can't access Rembrandt data

  • Verify the MCP server URL is correct: https://api.rembrandtagents.com/mcp

  • Check that your authorization code is valid (they expire — re-authorize if needed)

  • Restart Claude Desktop after any configuration changes

  • Try removing and re-adding the MCP server

Connection was working but stopped

  • Authorization codes can expire. Re-authorize by going through the setup flow again.

  • Check that your Rembrandt account and organization are still active

Disconnecting

To disconnect the MCP integration:

  1. Remove the Rembrandt MCP server from Claude Desktop settings

  2. Restart Claude Desktop
