QuerySail: Google Analytics

QuerySail: Google Analytics MCP server

QuerySail is a hosted MCP server for Google Analytics 4. Connect it to ChatGPT, Claude, Codex, Cursor or VS Code, sign in, connect your Google account once, and ask about your traffic, engagement and conversions in plain language. There is nothing to install, no Google Cloud project and no API key to paste.

• Endpoint: https://mcp.querysail.com/ga4/mcp (Streamable HTTP, OAuth 2.1 with dynamic client registration)
• Website: https://querysail.com/google-analytics
• Pricing: included in the same plan as QuerySail for Google Search Console. 7-day free trial, no card required, then $8/month. See https://querysail.com/pricing.

This repository holds the public listing files (MCP Registry server.json, a Claude Code plugin, client configs). The service itself is hosted at querysail.com; its source is not published here.

Tools

All tools are read-only. QuerySail cannot create or edit properties, data streams, key events, audiences or any other Google Analytics setting.

Example prompts

• How many users and sessions did my site have in the last 28 days?
• Which channels brought the most sessions last month, and how did that change from the month before?
• What are my top landing pages by key events?
• How many people are on the site right now, and from which countries?
• Compare organic search sessions with the same weeks last year.

Setup

You need a QuerySail account with Google Analytics connected: sign up at https://querysail.com and choose Connect Google Analytics under Account → Connections. Each client below opens a browser window to sign in the first time.

Claude Code

claude mcp add --transport http --scope user querysail-ga4 https://mcp.querysail.com/ga4/mcp

Then run /mcp, choose querysail-ga4 and sign in. Or install it as a plugin, which also adds a Google Analytics analysis skill:

/plugin marketplace add querysail/querysail-ga4/plugin install querysail-ga4@querysail-ga4

Claude Desktop and claude.ai

Open Customize → Connectors, select + Add → Add custom connector, name it QuerySail GA4 and paste https://mcp.querysail.com/ga4/mcp as the server URL.

ChatGPT

Turn on Developer mode under Settings → Security and login, go to chatgpt.com/plugins, select the plus button and paste the endpoint as the connection URL.

Clients that only run local commands

Use the mcp-remote bridge (needs Node.js):

{  "mcpServers": {    "querysail-ga4": { "command": "npx", "args": ["mcp-remote", "https://mcp.querysail.com/ga4/mcp"] }  }}

Agent skill

The querysail-google-analytics skill tells coding agents such as Claude Code, Codex, Cursor and OpenCode which QuerySail tool to call for each question and how to report the numbers. Install it with the skills CLI (needs Node.js):

npx skills add https://querysail.com --skill querysail-google-analytics

• Reports are fetched from Google when asked and cached for at most 15 minutes; realtime reports are not cached. Universal Analytics properties are not supported.
