Screaming Frog Server

MCP server that exposes Screaming Frog SEO Spider crawl data as tool calls for any MCP-compatible AI assistant.

Built on top of the screamingfrog Python library.

Requirements

• Python 3.10+
• Java runtime (for .dbseospider files with Derby backend)
• Screaming Frog SEO Spider installed (optional, for .seospider conversion)

Installation

git clone https://github.com/acamolese/screaming-frog-mcp.git
cd screaming-frog-mcp
pipx install -e .

Or with pip in a virtual environment:

pip install -e .

After installation, find the full path to the command:

which screaming-frog-mcp

You will need this path for the configuration below (typically ~/.local/bin/screaming-frog-mcp when installed via pipx).

Configuration

The MCP server needs to be registered in the config file of your MCP client. The file location and format vary depending on the client you use.

Claude Code (CLI)

Add to ~/.claude/.mcp.json:

{
  "mcpServers": {
    "screaming-frog-seo": {
      "type": "stdio",
      "command": "/full/path/to/screaming-frog-mcp"
    }
  }
}

Claude Desktop (macOS app)

Add to ~/Library/Application Support/Claude/claude_desktop_config.json, inside the existing mcpServers object:

{
  "mcpServers": {
    "screaming-frog-seo": {
      "command": "/full/path/to/screaming-frog-mcp"
    }
  }
}

Note: Claude Desktop does not use the "type": "stdio" field. If the file already contains other MCP servers, just add the "screaming-frog-seo" entry alongside them.

Other MCP clients

Refer to your client's documentation. The server uses stdio transport and the command is the path to screaming-frog-mcp.

Important: Always use the absolute path to the command (from which screaming-frog-mcp) rather than just the name, to avoid PATH resolution issues.

After editing the config, restart the application or session for changes to take effect.

Slash command for automated analysis

mkdir -p ~/.claude/commands
curl -o ~/.claude/commands/analyze-crawl.md \
  https://raw.githubusercontent.com/acamolese/screaming-frog-mcp/main/commands/analyze-crawl.md

Then type /analyze-crawl in a new session. The command will ask for your crawl file and automatically run all audits, presenting a structured report.
