Best MCP Server for On-Page SEO (2026)

Why Use an MCP Server for On-Page SEO?

On-Page SEO traditionally requires switching between browser-based tools, spreadsheets, and your development environment. An MCP server eliminates that context switching by bringing on-page seo data directly into your AI assistant.

Instead of copying data from Ahrefs into a chat window, you ask Claude or Cursor to run the analysis. The MCP server fetches live data, and the AI interprets it in context. This is faster and produces better results because the AI sees the full picture.

Top MCP Options for On-Page SEO

1. Delulu9 – Best for Keyword-Driven On-Page SEO

Delulu9 is the most complete MCP server for on-page seo when keywords are involved. It provides:

• Google, Bing, and Reddit keyword data in a single query
• CSP classification built into every result
• H1 Tag scoring for realistic opportunity assessment
• $12/mo flat rate with 1,000 requests/hour

For on-page seo specifically, Delulu9 excels because it combines data sources that other tools keep separate. You get a unified view of keyword opportunities across search engines and Reddit discussions.

2. Community Wrappers for Dedicated Tools

If you need on-page seo capabilities beyond keyword research (like International SEO), community-built MCP wrappers for tools like Ahrefs and HubSpot can help. These wrap existing APIs but require separate subscriptions and more setup effort.

3. Custom MCP Servers

For advanced on-page seo workflows, you can build a custom MCP server using the MCP SDK. This makes sense if you have proprietary data sources or need to combine multiple APIs into a single interface.

How to Set Up On-Page SEO with MCP

Claude Code Setup

{
  "mcpServers": {
    "delulu9": {
      "command": "npx",
      "args": ["-y", "@delulu9/seo-mcp-server@latest"],
      "env": {
        "DELULU9_API_KEY": "your-api-key"
      }
    }
  }
}

Once connected, you can ask Claude:

• “Find keyword opportunities for on-page seo”
• “Analyze on-page seo data for my site”
• “Compare on-page seo metrics across competitors”

Cursor Setup

Add the same configuration to Cursor’s MCP settings. The protocol is identical, so any MCP server that works in Claude Code also works in Cursor.

On-Page SEO MCP Workflow Examples

Quick On-Page SEO Check

Ask your AI assistant: “Run a quick on-page seo check for [your domain/keyword]. Summarize the top findings.”

The MCP server fetches the data, and the AI presents actionable insights without you leaving your editor.

Deep On-Page SEO Analysis

For thorough on-page seo, chain multiple MCP queries:

1. Pull seed keywords for your niche
2. Analyze search intent distribution
3. Identify keyword gaps vs competitors
4. Generate a prioritized action list

This entire workflow happens in a single AI conversation.
