What Windsor.ai is
Windsor.ai is a marketing data-integration platform with 350+ sources and destinations including Looker Studio, Sheets, Power BI, BigQuery and Snowflake. Windsor MCP is included on every plan: free for one source, Basic $23/month ($19 yearly) for three sources, Standard $118/month ($99 yearly) for seven, with higher tiers above. Windsor says its MCP fetches live from each platform's API and can make confirmed changes on platforms such as Google Ads and Meta Ads.
Why people look for Windsor.ai alternatives
Price model. Windsor prices by number of data sources. Three is cheap; seven jumps to $118/month billed monthly. If you want GA4, Google Ads, Microsoft Advertising, Search Console, Bing, Tag Manager and YouTube all in Claude, a flat price can work out lower.
You only want the AI part. Windsor is a full data pipeline. If you never open Looker Studio and only ask questions in Claude or ChatGPT, a connector built just for that may be simpler.
Task-shaped tools. Windsor exposes fields from each source. Some marketers want tools shaped around questions - wasted search terms, impression share lost to budget, pages not indexed - so answers need less prompting.

The 7 alternatives
1. Caybl.ai
Caybl.ai is a hosted MCP connector and built-in AI assistant for Google Analytics 4, Google Ads, Microsoft Advertising, Search Console, Bing Webmaster Tools, Tag Manager, YouTube and PageSpeed - queried live, nothing stored. Google Analytics is free with unlimited questions in your own AI; Pro is a flat $29/month for every other source, so adding a fourth or sixth source costs nothing. Google Ads tools are shaped around marketing tasks, with a per-account write switch and dry runs. It has no BI or warehouse destinations and covers eight sources, not hundreds - no Meta yet (coming soon), TikTok or Shopify.
Best for: Marketers who only need answers in Claude or ChatGPT about Google data plus Bing.
2. Supermetrics
Supermetrics is a marketing data platform, and Supermetrics MCP gives Claude, ChatGPT, Copilot, n8n and other MCP clients access to its sources - Google Ads, Meta, LinkedIn, TikTok, Microsoft Ads, GA4, HubSpot, Salesforce, Shopify and more - through one connection. Supermetrics says MCP access comes with its subscriptions (its FAQ ties it to plans that include Data API access) and offers a 14-day free trial without a card. It doesn't publish one simple MCP price: plans depend on which sources you need.
Best for: Larger marketing teams and agencies that already use Supermetrics for reporting.
3. Porter Metrics
Porter Metrics is known for its Looker Studio connectors and has an MCP connector for Claude, ChatGPT and Gemini, included on every plan. Reporting is priced per connected data source account - $15/month for one, $39.99 for three, falling per account with volume - across 30+ sources including Meta, Google Ads, GA4, Search Console, TikTok and Shopify. A separate Automation product lets the AI act in ad platforms for credits, with campaigns created paused. Its free-forever plan limits history to 30 days.
Best for: Teams already on Looker Studio, or anyone connecting just one to three accounts.
4. Markifact
Markifact is a marketing AI platform built around its MCP connector, listed in Claude's directory, with about 45 integrations including 14 ad platforms, GA4, Search Console, Bing Webmaster Tools, SEMrush and Ahrefs, plus workflow templates and bulk uploaders. Writes are approval-gated. It's priced per seat with credits rather than per source: Pro $79/month (one seat, 2,500 or 5,000 credits), Team $249/month. There are no BI destinations; it's AI-first.
Best for: Performance marketers running several ad platforms who want templates and bulk actions in AI.
5. Coupler.io
Coupler.io is a data-integration tool that builds data flows from 400+ sources into spreadsheets, BI tools and AI tools, with Claude, ChatGPT and a custom MCP among its AI destinations. The AI works from the data sets in flows you've pointed at it, which refresh on a schedule or on demand - a different model from querying each platform live. It has a free plan for one source, and paid plans from $32/month ($24/month billed yearly). Check which plans include the AI destinations before committing.
Best for: People who already move data with Coupler.io and want the same data sets in an AI chat.
6. Composio
Composio is a developer platform with 1,500+ toolkits behind one MCP endpoint and an SDK, including Google Analytics, Google Ads and Search Console. Its Google Ads toolkit is broad (36 tools, mostly general Ads API mutate wrappers plus GAQL search), so the AI does more of the work of knowing which call to make. The free Hobby tier includes 100,000 tool calls a month; Pro is $29/month with $29 of usage included. It isn't marketing-specific, which is the point if you also want Gmail, Slack or a CRM in the same agent.
Best for: Developers building agents across many apps, or anyone wanting one connector for everything.
7. Google's own GA4 and Google Ads MCP servers
Google publishes open-source MCP servers for Google Analytics and Google Ads on GitHub. They're free and come from Google's own GitHub organisations, but you run them yourself: Python with pipx, a Google Cloud project with the right APIs enabled, and your own credentials (plus Google Ads API access for production Ads accounts). The GA4 server is read-only unless you start it with a write flag; the Ads server's listed tools retrieve data. There's no hosted version, so each teammate sets it up on their own machine or you deploy and secure it yourself.
Best for: Engineers who want free, self-hosted, Google-only access and don't need changes or a shared setup.
How to choose
- If you need dashboards or a warehouse as well as AI, the closest like-for-like alternatives are Supermetrics, Porter Metrics and Coupler.io - or stay with Windsor.
- If you only ask questions in Claude or ChatGPT and your stack is Google plus Bing, Caybl.ai is simpler and flat-priced.
- If you want many ad platforms and workflow templates in AI, look at Markifact.
- If you're building your own agent, Composio; if you want free and self-hosted, Google's own servers.
