Windsor MCP

How to Install and Use Windsor MCP

Windsor MCP is a tool that lets your large language model (LLM) access your full business data without needing SQL or coding. Here’s an easy guide to installing and using Windsor MCP with simple steps and examples.

Option 1: Using Windsor MCP with Claude Desktop (Recommended)

If you use Claude Desktop with a Pro or higher plan, this is the easiest way to get started.

First, make sure you have a Claude Pro plan and your Windsor API key ready. Then, follow these steps:

1. Open Claude Desktop and go to Settings → Connectors → Add custom connector.
2. Enter one of these URLs for Windsor MCP:

   https://mcp.windsor.ai
   

   or

   https://mcp.windsor.ai/sse
   

3. Start a new chat in Claude, and type:

   My Windsor.ai API key is {your-key}. {Your question here}
   

   Replace {your-key} with your actual API key and ask your business questions.
4. Accept any connector permissions that appear, and then start querying your integrated data.

Option 2: Setup with Developer Proxy for Advanced Users

For those needing more control or on lower Claude plans, this option uses a developer proxy.

You’ll first install the MCP proxy tool using:

uv tool install mcp-proxy

Then, get the full path of the installed proxy by running:

which mcp-proxy

Next, open Claude Desktop Settings, go to Developer → Edit Config, and add this JSON snippet:

{
  "mcpServers": {
    "windsor": {
      "command": "/Users/{your-username}/.local/bin/mcp-proxy",
      "args": ["https://mcp.windsor.ai/sse"]
    }
  }
}

Make sure to replace "/Users/{your-username}/.local/bin/mcp-proxy" with the path you copied and use your system username. After saving, fully quit and reopen Claude. You will see “windsor” available in your MCP options.

Option 3: Using Windsor MCP with Cursor Desktop

If you have Cursor Desktop, here’s how you can add Windsor MCP:

First, install the MCP proxy just like in option 2:

uv tool install mcp-proxy

Find the full path:

which mcp-proxy

Open Cursor Desktop, go to Tool & Integrations → New MCP Server. A file named mcp.json will open. Paste this configuration there:

{
  "mcpServers": {
    "windsor": {
      "command": "/Users/{your-username}/.local/bin/mcp-proxy",
      "args": ["https://mcp.windsor.ai/sse"]
    }
  }
}

Save the file after replacing the path. When you use Windsor MCP in Cursor, it will ask for your API key. Just paste it and start asking your data questions.
