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.
