Windsor MCP — Connect Claude, ChatGPT and Cursor to 325+ marketing data sources

Windsor MCP (Model Context Protocol) is a hosted MCP server that lets your AI assistant query, explore and analyze live business data from 325+ sources — Meta Ads, Google Ads, TikTok Ads, GA4, HubSpot, Salesforce, Shopify, Stripe, BigQuery, Snowflake and many more — with no SQL, no API keys, and no custom integrations. On connectors that support it, agents can also execute write actions — for example pausing or enabling ad campaigns and adjusting budgets on Meta Ads, Google Ads and TikTok Ads.

It works with Claude, ChatGPT, Microsoft Copilot, Perplexity, Cursor, Windsurf, Cline, GitHub Copilot, Gemini, Manus, and any MCP-compatible client.

TL;DR

• Native connector in Claude (in the Claude directory) and ChatGPT (as a ChatGPT app).
• Read and write: query data from 325+ sources, and execute write actions (e.g. pause/enable ad campaigns) on connectors that expose them.
• OAuth 2.0 — sign in once at Windsor.ai, no API keys to manage.
• Free forever plan available at Windsor.ai; some LLM providers (e.g. Claude) require a paid plan to use connectors.
• Live, machine-readable docs for AI agents at /llms.txt, /llms-full.txt, and /datasources.

🌟 Features

Natural-language access to business data

Ask questions like:

• "What campaigns had the best ROAS last month?"
• "Give me a breakdown of spend by channel over the past 90 days."
• "Which campaigns are wasting our advertising budget?"
• "How many HubSpot deals closed this month, and which ad spend drove them?"
• "Pull our Shopify orders and Stripe payments for this quarter."
• "Combine GA4 sessions with Google Ads spend into a weekly report."

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

Write actions, not just reads

Ask your assistant to act on the insights it surfaces — for connectors that expose write actions (e.g. Meta Ads, Google Ads, TikTok Ads):

• "Pause my underperforming Meta Ads campaigns from last week."
• "Re-enable the Google Ads campaign 'Summer Sale 2026'."
• "Cut the daily budget on this TikTok Ads campaign by 20%."

Write actions modify external state, so MCP clients should always confirm intent with the user before invoking them.

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

Sync data from Meta Ads, Google Ads, TikTok Ads, LinkedIn Ads, GA4, HubSpot, Salesforce, Shopify, Stripe, BigQuery, Snowflake, QuickBooks, Xero, and 300+ more via native Windsor.ai connectors. Full live list at mcp.windsor.ai/datasources.
