TrueSource GEO MCP Server

AI-Readiness auditing as an MCP tool surface — for Claude Desktop, Cursor, VS Code Copilot, and 70+ other MCP clients.

What is this?

This is a Model Context Protocol (MCP) server that exposes TrueSource's GEO-Audit methodology as standardized tools. Any MCP-compatible AI assistant can:

• Audit websites for AI-readiness (robots.txt, llms.txt, schema markup, E-E-A-T signals)
• Generate GEO files (AI-optimized robots.txt, llms.txt)
• Create VibeTags for emotional AI brand resonance
• Check robots.txt for AI bot allow/block status

Quick Start

Option A: npx (Recommended)

⚠️ The -y flag is critical — without it, npx silently waits for install confirmation in the background and the server freezes.

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "truesource": {
      "command": "npx",
      "args": ["-y", "truesource-geo-mcp"],
      "env": {
        "TRUESOURCE_API_KEY": "your-api-key-here"
      }
    }
  }
}

Cursor / VS Code

Add to .cursor/mcp.json or VS Code MCP settings:

{
  "mcpServers": {
    "truesource": {
      "command": "npx",
      "args": ["-y", "truesource-geo-mcp"],
      "env": {
        "TRUESOURCE_API_KEY": "your-api-key-here"
      }
    }
  }
}

Option B: Local Build

cd packages/geo-mcp
npm install
npm run build

{
  "mcpServers": {
    "truesource-geo": {
      "command": "node",
      "args": ["/absolute/path/to/packages/geo-mcp/build/index.js"],
      "env": {
        "TRUESOURCE_API_KEY": "your-api-key-here"
      }
    }
  }
}

3. Restart Your MCP Host & Use

Ask your AI assistant:

• "What's the AI-readiness score for my-website.com?"
• "Generate a robots.txt for https://example.com"
• "Check which AI bots are blocked on competitor.com"
• "Create VibeTags for our brand at my-website.com"

Available Tools

Tool	Trigger	Description
geo_score	"audit", "score", "check AI readiness"	Full AI-readiness audit → 0-100 score, grade, checks, recommendations
geo_inject	"generate robots.txt", "create llms.txt"	Generate AI-optimized robots.txt + llms.txt (ready to deploy)
vibetags_generate	"brand perception", "VibeTags", "how AI sees"	Emotional AI brand resonance analysis (4-layer VibeGap Bridge)
geo_check_robots	"robots.txt", "which bots blocked"	Quick robots.txt AI bot status check (9 bots)

Environment Variables

Variable	Required	Default	Description
TRUESOURCE_API_KEY	Yes	—	API key for Railway backend authentication
TRUESOURCE_API_URL	No	Railway production URL	GEO-Inject API base URL
TRUESOURCE_TIMEOUT	No	30000	Request timeout in ms (MCP hosts timeout at ~60s)

Testing with MCP Inspector

npm run inspect

This opens the interactive MCP Inspector at http://localhost:6274, where you can:

• See all registered tools and their schemas
• Invoke tools with test data
• Inspect JSON-RPC request/response pairs
