Connects Claude to the QuantaRoute Geocoding API with a focus on Indian addresses and DigiPin codes. You get geocoding and reverse geocoding, coordinate to DigiPin conversion, address autocomplete, and batch operations for up to 100 addresses at once. The location lookup tools pull administrative boundaries, pincodes, states, and locality data from a dataset of 36,000+ postal boundaries across India. Includes validation for DigiPin format, API usage stats, and health checks. Requires a QuantaRoute API key. The package also ships with a REST wrapper deployed at mcp-gc.quantaroute.com if you need HTTP endpoints instead of MCP tools.
A Model Context Protocol (MCP) server that provides AI assistants (Claude Desktop, Cursor, and more) with powerful geocoding, location lookup, and DigiPin processing capabilities using the QuantaRoute Geocoding API.
Package: @quantaroute/mcp-server (MCP Server for AI Agents)
SDK: quantaroute-geocoding (Node.js/TypeScript SDK)
✅ Fully compatible with Claude Desktop and Cursor
This MCP server is compatible with Claude Desktop and Cursor. Follow the instructions below for your platform.
Locate the Claude Desktop configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json~/.config/Claude/claude_desktop_config.jsonEdit the configuration file and add:
{
"mcpServers": {
"quantaroute": {
"command": "npx",
"args": [
"-y",
"@quantaroute/mcp-server"
],
"env": {
"QUANTAROUTE_API_KEY": "your-api-key-here"
}
}
}
}
Add to your MCP configuration file (~/.cursor/mcp.json):
{
"mcpServers": {
"quantaroute": {
"command": "npx",
"args": [
"-y",
"@quantaroute/mcp-server"
],
"env": {
"QUANTAROUTE_API_KEY": "your-api-key-here"
}
}
}
}
Restart Cursor after making changes.

This project includes a REST API wrapper that makes all MCP tools accessible via HTTP endpoints for mobile and web applications.
The REST API is already deployed and ready to use at:
Base URL: https://mcp-gc.quantaroute.com/api
Note: mcp-gc stands for MCP Geocoding. This follows the naming convention:
mcp-gc.quantaroute.com - Geocoding MCP Server (this project)1. Get API Information:
curl https://mcp-gc.quantaroute.com/api
2. Geocode an Address:
curl -X POST https://mcp-gc.quantaroute.com/api/geocode \
-H "Content-Type: application/json" \
-H "x-api-key: your-api-key-here" \
-d '{
"address": "Rohra Address, New Town",
"city": "New Town",
"state": "West Bengal",
"pincode": "700163"
}'
3. Health Check:
curl -X GET https://mcp-gc.quantaroute.com/api/health \
-H "x-api-key: your-api-key-here"
4. Find Nearby Boundaries:[NOT RELEASED, COMING SOON...]
curl -X POST https://mcp-gc.quantaroute.com/api/find-nearby-boundaries \
-H "Content-Type: application/json" \
-H "x-api-key: your-api-key-here" \
-d '{
"latitude": 28.6139,
"longitude": 77.2090,
"radius_km": 5.0,
"limit": 10
}'
This endpoint finds nearby postal boundaries within a specified radius. Useful for:
// Geocode an address
const response = await fetch('https://mcp-gc.quantaroute.com/api/geocode', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'x-api-key': 'your-api-key-here'
},
body: JSON.stringify({
address: 'Rohra Address, Action Area I',
city: 'New Town',
state: 'West Bengal'
})
});
const data = await response.json();
console.log(data);
import requests
# Geocode an address
response = requests.post(
'https://mcp-gc.quantaroute.com/api/geocode',
headers={
'Content-Type': 'application/json',
'x-api-key': 'your-api-key-here'
},
json={
'address': 'Rohra Address, Action Area I, Ghuni',
'city': 'New Town',
'state': 'West Bengal'
}
)
data = response.json()
print(data)
If you want to deploy your own instance:
Deploy to Vercel:

vercel env add QUANTAROUTE_API_KEY
Configure Custom Domain (optional):
For complete REST API documentation, see API.md.
Available Endpoints:

Request Header (Recommended for production):
x-api-key: your-api-key-here
x-api-key header with each requestEnvironment Variable (Optional fallback for testing):
QUANTAROUTE_API_KEY=your-api-key-here
x-api-key header is providedPriority: The request header takes precedence over the environment variable.
Getting an API Key:
x-api-key header for all API requests# Install dependencies
npm install
# Build the project
