seo-stack-mcp
The complete open-source SEO data stack for AI agents. Google Search Console, Google Analytics 4, Bing Webmaster Tools, Microsoft Clarity, Google AdSense, Google Keyword Planner and Open PageRank in a single MCP server — with built-in analyst tools (cannibalization check, low-hanging fruit, content gap, weekly report), not just raw API wrappers.
Self-hosted, free, MIT. Works with Claude Desktop, Claude Code, Cursor, and any MCP client.
Why this instead of N separate servers?
- One install, one config — instead of wiring up 7 different MCP servers with 7 auth setups.
- Analyst tools included — ask "which queries are declining this month?" or "find my low-hanging-fruit keywords" and get an answer computed server-side, not a raw data dump your agent has to crunch.
- Sources are optional — configure only what you use; tools appear only for configured sources.
- Self-hosted — your tokens stay on your machine. No third-party hosted gateway reading your Search Console.
Quickstart (60 seconds)
Add to your MCP client config (Claude Desktop claude_desktop_config.json, Cursor mcp.json, or claude mcp add):
{
"mcpServers": {
"seo-stack": {
"command": "uvx",
"args": ["seo-stack-mcp"],
"env": {
"GOOGLE_APPLICATION_CREDENTIALS": "/path/to/service-account.json",
"GA4_PROPERTY_ID": "123456789",
"BING_WEBMASTER_API_KEY": "your-key",
"CLARITY_API_TOKEN": "your-token"
}
}
}
}
Every env var is optional — set only the sources you want. That's it: restart your client and ask "what are my top queries this week?".
To run the latest development version straight from GitHub, use "args": ["--from", "git+https://github.com/Raffaele86/seo-stack-mcp", "seo-stack-mcp"] instead.

Why not the official GA4 server or mcp-gsc?
Both are good and this project doesn't pretend otherwise. Google's official analytics-mcp covers GA4 only; mcp-gsc covers GSC only. If you live in one data source, use them. This project is for people who work across the whole free SEO stack and want the cross-source workflow (GSC + GA4 + Bing + Clarity) plus opinionated analysis tools in one place.
