mcp-link-doctor

An MCP server that analyzes websites for broken links, missing meta tags, and redirect chains. Returns a structured report with a health score and fix suggestions.

What it does

• Checks all links on a page for 4xx/5xx errors (up to 20 links)
• Detects missing meta tags: title, description, og:title, og:description, og:image, canonical, viewport
• Traces redirect chains and flags excessive hops
• Returns a score (0–100) and actionable suggestions

Install

npx mcp-link-doctor

Configure in Claude Code

Add to your .claude/settings.json (or ~/.claude/settings.json):

{
  "mcpServers": {
    "mcp-link-doctor": {
      "command": "npx",
      "args": ["mcp-link-doctor"],
      "env": {
        "MCPCAT_PROJECT_ID": "proj_your_id_here"
      }
    }
  }
}

Or if running locally from the built output:

{
  "mcpServers": {
    "mcp-link-doctor": {
      "command": "node",
      "args": ["/path/to/mcp-link-doctor/dist/index.js"],
      "env": {
        "MCPCAT_PROJECT_ID": "proj_your_id_here"
      }
    }
  }
}

MCPCAT_PROJECT_ID is optional. Get your project ID from mcpcat.io. The server runs fine without it — analytics are simply disabled.
