SEO MCP Server

SEO MCP Server is a Model Context Protocol (MCP)–based SEO analysis server that enables AI assistants and LLMs to perform real-time SEO validation, audits, and analysis via a standardized protocol.

Key Features

MCP Protocol: Standards-compliant MCP server for seamless integration with AI assistants.
Real-Time SEO Analysis: Run live SEO audits, validation, and analysis from any MCP-compatible client.
Comprehensive Validation: Inspect meta tags, headings, structured data, performance, accessibility, and more.
Cloudflare Workers: Deployed on Cloudflare’s edge network for low-latency, global access.
Landing Page: Modern React + Vite + Tailwind CSS landing page with responsive design.

How It Works

The server exposes SEO analysis tools through the MCP protocol so assistants like Claude, GPT, and others can:

Programmatically audit websites
Check SEO compliance
Generate actionable recommendations

All of this is driven through natural language interactions with the assistant, which calls the MCP tools behind the scenes.
