How to: Cursor Web Validator by DigestSEO validate_html

client:Cursor transport:streamable-http tool:validate_html

Add Web Validator by DigestSEO to Cursor

  1. 01

    Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "mcp-web-validator": {
      "url": "https://web-validator-mcp.digestseo.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

    Ask for something validate_html does. Cursor lists the server's tools on connect and calls validate_html itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Web Validator by DigestSEO's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
