@gener8v/mcp-geographic-data

MCP server for the loc8n Geographic Data API. Exposes U.S. demographics, housing, mortgage, migration, employment, and geographic data as tools for any MCP-compatible client (Claude Desktop, Claude Code, Cursor, etc.).

Quick Start

npm install -g @gener8v/mcp-geographic-data

Set your API key:

export LOC8N_API_KEY="your-api-key"

Get a key at loc8n.com.

Usage

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "geographic-data": {
      "command": "mcp-geographic-data",
      "env": {
        "LOC8N_API_KEY": "your-api-key"
      }
    }
  }
}
Claude Code

Add to your project's .mcp.json:

{
  "mcpServers": {
    "geographic-data": {
      "command": "mcp-geographic-data",
      "env": {
        "LOC8N_API_KEY": "your-api-key"
      }
    }
  }
}
Hosted SSE (no install required)

Connect any MCP-compatible client directly to the hosted server at mcp.loc8n.com. Pass your API key as a query parameter or Authorization header:

SSE endpoint: https://mcp.loc8n.com/sse?apiKey=YOUR_API_KEY

Or with a Bearer token:

GET https://mcp.loc8n.com/sse
Authorization: Bearer YOUR_API_KEY

Each connection gets an isolated session — your API key is used for all requests and usage is tracked against your account.

Cursor

Add to your Cursor MCP settings:

{
  "mcpServers": {
    "geographic-data": {
      "url": "https://mcp.loc8n.com/sse?apiKey=YOUR_API_KEY"
    }
  }
}
Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "geographic-data": {
      "serverUrl": "https://mcp.loc8n.com/sse?apiKey=YOUR_API_KEY"
    }
  }
}
Self-Hosted SSE

Run the server locally for development or custom deployments:

mcp-geographic-data --transport sse --port 3100

Endpoints:

  • SSE: http://localhost:3100/sse
  • Messages: http://localhost:3100/messages
  • Health: http://localhost:3100/health
