marlo-mcp

An MCP server that lets Claude, Cursor and other AI assistants audit a web page for SEO and technical issues with Marlo, the open-source AI CMO.

Ask your assistant things like:

• "Audit https://mysite.com and tell me what to fix first."

• "Check this page before I ship it."

It has one tool, audit_site. It is read-only: it fetches the page and changes nothing. It checks one page, and returns the top findings, each with evidence, why it matters and a concrete fix.

Install

Add it to your MCP client. For Claude Desktop, Cursor, Windsurf and similar clients:

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

For Claude Code: claude mcp add marlo -- npx -y marlo-mcp

Requires Node.js 20 or newer.

Use your own Marlo server

By default the tool calls the hosted Marlo at https://app.marlo.mlforge.in, which rate limits public audits. To use your own self-hosted Marlo instead:

{
  "mcpServers": {
    "marlo": {
      "command": "npx",
      "args": ["-y", "marlo-mcp"],
      "env": { "MARLO_BASE_URL": "http://localhost:3000" }
    }
  }
}

What it sends

Only the page address you ask about, to Marlo's public audit endpoint. No API keys, files or conversation text leave your machine. Private and local addresses are refused by the server.

Limits

• One page per call, and the top three findings. The full product tracks findings over time, checks AI readiness (GEO), reads Search Console and opens draft fix PRs on GitHub.

• The hosted endpoint is rate limited. If you hit the limit, the tool says so and when to retry.
