LinkMeta MCP Server

MCP server for LinkMeta — extract rich metadata (Open Graph, Twitter Cards, favicon, JSON-LD, body text, redirect chains) from any URL, directly from AI assistants like Claude, Cursor, and VS Code.

No API key required. Free forever.

Quick Start

Add to your claude_desktop_config.json:

    "linkmeta": {
      "command": "npx",
      "args": ["-y", "linkmeta-mcp"]
    }
  }
}

Then ask Claude:

"Extract the metadata from https://github.com and show me the Open Graph tags"

"Validate the SEO metadata for my website at https://example.com"

"Get the title and description from these 5 URLs and compare them"

"Check the redirect chain for https://bit.ly/some-link"

"Extract the clean body text from this article for summarization"

Architecture

Claude / Cursor / VS Code
        |
        | stdio (MCP protocol)
        v
  linkmeta-mcp
        |
        | HTTPS (REST API)
        v
  linkmeta.dev

This is a thin stdio MCP client that translates tool calls into REST API requests against the LinkMeta API at https://linkmeta.dev. No data is stored locally — all operations are stateless pass-throughs.
