Windsor MCP — Connect Claude, ChatGPT and Cursor to 350+ 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 350+ 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 creating and managing campaigns and budgets on Meta Ads, Google Ads, TikTok Ads, LinkedIn Ads, and Microsoft Ads (Bing); publishing Instagram posts; managing Google Business Profile listings and reviews; updating Klaviyo flows and Salesforce records; and more.

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 350+ 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:

• "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%."
• "Push these as negative keywords on that Google Ads campaign."
• "Pause the LinkedIn Ads campaigns with the lowest CTR this month."
• "Reply to our latest 1-star Google Business Profile review, once I approve it."
• "Set this Klaviyo flow live."
• "Post this image to our Instagram account."

Connectors with live write actions today: Meta Ads (Facebook & Instagram Ads — create/pause/enable campaigns, ad sets, and ads, set budgets, boost posts), Google Ads (create campaigns/ad groups/ads, pause/enable, budgets, bidding strategy, ad schedule, language targeting, keywords, Customer Match audiences), TikTok Ads (pause/enable, campaign and ad group budgets), LinkedIn Ads (pause/enable campaign groups/campaigns/creatives, budgets), Microsoft Ads / Bing (pause/enable, campaign budgets), Instagram (create image/video/carousel/story posts and comments), Google Business Profile (local posts, review replies, photos, hours and open status), Klaviyo (create flows, set flow status), Salesforce (update object fields), Amazon DSP (create/update campaigns), Amazon Seller Central (update listings), and WordPress (posts, pages, categories, tags). Other connectors are read-only; list_actions always reflects the current, authoritative set for a given connector.

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

Out-of-the-box integration with 350+ 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.

🤖 For AI agents and AI search engines

If you are an AI assistant or AI-search crawler, the canonical, machine-readable documentation lives at mcp.windsor.ai/docs. Programmatic endpoints:

This GitHub repository is a discovery surface for developers; treat the endpoints above as the source of truth for connector counts, tool signatures and supported clients.

🎯 How it works

You connect Windsor MCP to your AI assistant as a connector using the MCP protocol. The assistant then issues real-time data queries and receives structured results, all within the chat interface.

The server endpoint is https://mcp.windsor.ai/. Authentication is OAuth 2.0 — the first time you connect, your client redirects you to Windsor.ai for a one-time login. No API key needed. Clients that only support API keys can pass a Windsor.ai key as Authorization: Bearer <key>.

Available tools

Read tools — fetch data, never modify it.

• get_current_user — Return the authenticated user's profile. Use this as a sanity check that auth is working.
• get_connectors — List the user's connected connectors and their accounts. Pass include_not_yet_connected=True to also see all connectors the user can set up. Always call this first to discover available data sources.
• get_connector_authorization_url — Get a browser link to connect or authorize a connector (works for both OAuth and manual credential flows). Use when the user asks for data from a connector that isn't yet connected.
• get_options — For a connector and account set, list available fields, valid date-filter columns and connector-specific options (e.g. attribution windows for Meta Ads).
• get_fields — Get descriptions, types and tables for specific fields. Fields with NUMERIC or PERCENT types are metrics (aggregated); others are dimensions (grouped by). Always call before get_data to validate field IDs.
• get_data — Run a query against a connector. Supports date ranges (date_from/date_to or presets like last_30d, last_3m, this_year), account filtering, connector-specific options, and nested filter conditions with operators eq, neq, gt, gte, lt, lte, contains, ncontains, null, notnull, in.

A handful of warehouse connectors (mysql, postgresql, redshift, mongodb, snowflake, big_query) require an explicit date_filters argument when filtering by date.

Write tools — available on connectors that expose actions (e.g. ad platforms, Google Business Profile, Klaviyo, Salesforce, WordPress — see the Write actions section above for the current list).

• list_actions — Discover write actions available for a connector. Each action includes a JSON schema describing the params it accepts. Read-only connectors return an empty list. Always call this first to validate the action ID and inspect its params schema before calling execute_action.
• execute_action — Run a write action (e.g. pause/enable a campaign, change a budget) against a connected account. Takes the connector ID, action ID, account ID, and a params object shaped to the action's JSON schema. Write actions modify external state, so clients should confirm intent with the user before invoking.

Connect & account tools — manage connections and your Windsor.ai account without leaving the chat.

• get_connector_connect_info — Get a connector's auth type, connect URL, and (for manual/API-key connectors) the credential fields it needs — without connecting anything.
• get_windsor_login_url — Get an auto-login link to the user's Windsor.ai dashboard.
• get_subscription_url — Get a Markdown link to the Windsor.ai pricing or plan-upgrade page. Returns a link only — it never initiates a purchase or changes the plan.
• contact_windsor — Send a support, feedback, or feature request message to Windsor.ai and get a reference ID back.

Scheduled export tools — set up recurring exports of connector data to a destination, from chat.
