Description from the maker (original English)
U.S. demographics, housing, mortgage, migration, and employment data via loc8n API
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

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.).
npm install -g @gener8v/mcp-geographic-data
Set your API key:
export LOC8N_API_KEY="your-api-key"
Get a key at loc8n.com.
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": { "geographic-data": { "command": "mcp-geographic-data", "env": { "LOC8N_API_KEY": "your-api-key" } } } }
Add to your project's .mcp.json:
{
"mcpServers": { "geographic-data": { "command": "mcp-geographic-data", "env": { "LOC8N_API_KEY": "your-api-key" } } } }
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.
Add to your Cursor MCP settings:
{
"mcpServers": { "geographic-data": { "url": "https://mcp.loc8n.com/sse?apiKey=YOUR_API_KEY" } } }
Add to ~/.codeium/windsurf/mcp_config.json:
{
"mcpServers": { "geographic-data": { "serverUrl": "https://mcp.loc8n.com/sse?apiKey=YOUR_API_KEY" } } }
Run the server locally for development or custom deployments:
