What It Does
GEO Analyzer examines content for the signals AI systems use when selecting sources to cite:
- Claim Density - Extractable facts per 100 words
- Information Density - Word count vs predicted AI coverage
- Answer Frontloading - How quickly key information appears
- Semantic Triples - Structured (subject, predicate, object) relationships
- Entity Recognition - Named entities AI can reference
- Sentence Structure - Optimal length for AI parsing
The analysis runs locally using Claude Sonnet 4.5 for semantic extraction. No external services, no data leaving your machine.
Installation
Claude Desktop
Add to your claude_desktop_config.json:
{
"mcpServers": {
"geo-analyzer": {
"command": "npx",
"args": ["-y", "@houtini/geo-analyzer@latest"],
"env": {
"ANTHROPIC_API_KEY": "sk-ant-..."
}
}
}
}
Config locations:
- Windows:
%APPDATA%\Claude\claude_desktop_config.json - macOS:
~/Library/Application Support/Claude/claude_desktop_config.json - Linux:
~/.config/Claude/claude_desktop_config.json
Restart Claude Desktop after saving.
Claude Code (CLI)
Claude Code uses a different registration mechanism -- it doesn't read claude_desktop_config.json. Use claude mcp add instead:
claude mcp add -e ANTHROPIC_API_KEY=sk-ant-... -s user geo-analyzer -- npx -y @houtini/geo-analyzer@latest
Verify with:
claude mcp get geo-analyzer
You should see Status: Connected.
Requirements
- Node.js 20+
- Anthropic API key (console.anthropic.com)
