🌟 Features

Natural language access to business data

Windsor MCP is a natural language interface that connects your integrated Windsor.ai datasets with the LLM platform, enabling you to better understand your data by asking questions like:

• “What campaigns had the best ROAS last month?”
• “Give me a breakdown of spend by channel over the past 90 days.”
• “What campaigns are wasting our advertising budget?”

All in real-time, directly inside your LLM chat interface.

Out-of-the-box integration with 325+ sources

Sync data from Facebook Ads, GA4, HubSpot, Salesforce, Shopify, TikTok Ads, and more via native Windsor.ai connectors.

Zero-code setup

Windsor MCP works via the Claude Desktop or with a lightweight dev proxy. No custom integrations required.

Open standard compatibility

Built on Anthropic’s open MCP spec, it’s compatible with Claude, Perplexity, Cursor, and more.

Real-time Analytics without SQL

Get instant breakdowns, summaries, and performance insights from your integrated data.

🎯 How It Works

You connect Windsor MCP to your preferred LLM as an external connector using the MCP protocol. The LLM can then issue real-time data queries and receive structured results, all within the chat interface.

Example prompts:

• What was total ad spend by channel last month?
• Break down ROAS for Meta vs Google Ads for Q2
• Are there any campaigns overspending vs target ROAS?
