Its documentation lists, in beta, a tool that creates or updates ad campaigns. V-Kit vs Supermetrics MCP

Windsor.ai

Windsor.ai runs a hosted MCP server at https://mcp.windsor.ai/ for Claude, ChatGPT, Copilot and other MCP clients; you sign in with a Windsor.ai account and connect data sources in Windsor.ai first. Its connectors page lists 350+ sources, including AppsFlyer, Adjust, Branch and Apple Search Ads; RevenueCat, App Store Connect and Google Play Console are not in it. Its documentation describes write-back actions on select platforms such as Meta Ads, Google Ads, TikTok Ads, LinkedIn Ads, Microsoft/Bing Ads and Amazon Seller Central. V-Kit vs Windsor.ai

When V-Kit fits

When your questions are about a mobile app: installs from AppsFlyer, subscriptions from RevenueCat, sales, analytics and reviews from App Store Connect, next to spend from Meta, Google Ads and TikTok — see V-Kit for mobile app marketing. V-Kit reads ad platforms and changes no campaigns. Both services above list platforms that V-Kit does not connect, such as LinkedIn Ads.
