REST API Wrapper

This project includes a REST API wrapper that makes all MCP tools accessible via HTTP endpoints for mobile and web applications.

Features

• ✅ RESTful API: All MCP tools exposed as HTTP endpoints
• ✅ Authentication: API key via header or environment variable
• ✅ CORS Support: Ready for web and mobile apps
• ✅ Vercel Ready: Optimized for serverless deployment
• ✅ Error Handling: Comprehensive error handling and validation

Quick Start

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)

Using the REST API

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:

• Finding all pincodes within X km of a location
• Discovering nearby administrative boundaries
• Location-based search and discovery

JavaScript/TypeScript Example

// 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);

Python Example

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)

Deploying Your Own Instance

If you want to deploy your own instance:

1. Deploy to Vercel:

   vercel
   

2. Set Environment Variable (optional, for testing):

   vercel env add QUANTAROUTE_API_KEY
   

3. Configure Custom Domain (optional):

   • Add your custom domain in Vercel
   • Configure DNS CNAME record pointing to Vercel
   • Wait for DNS propagation and SSL certificate

API Documentation

For complete REST API documentation, see API.md.

Available Endpoints:

• GET /api - API information
• GET /api/health - Health check
• GET /api/usage - Usage statistics
• GET /api/location-statistics - Location service statistics
• GET /api/autocomplete?q=query - Address autocomplete
• GET /api/validate-digipin?digipin=XXX-XXX-XXXX - Validate DigiPin
• POST /api/geocode - Geocode an address
• POST /api/reverse-geocode - Reverse geocode DigiPin
• POST /api/coordinates-to-digipin - Convert coordinates to DigiPin
• POST /api/batch-geocode - Batch geocode addresses
• POST /api/lookup-location-from-coordinates - Lookup from coordinates
• POST /api/lookup-location-from-digipin - Lookup from DigiPin
• POST /api/batch-location-lookup - Batch location lookup
• POST /api/find-nearby-boundaries - Find nearby boundaries [COMING SOON...]

Authentication

The API supports authentication in two ways:

1. Request Header (Recommended for production):

   x-api-key: your-api-key-here
   

   • Users should get their own API key from developers.quantaroute.com
   • Send the API key in the x-api-key header with each request
   • Each user's API key is validated by the backend API and usage is tracked separately

2. Environment Variable (Optional fallback for testing):

   QUANTAROUTE_API_KEY=your-api-key-here
   

   • Only used if no x-api-key header is provided
   • Useful for testing and development
   • Not recommended for production use

Priority: The request header takes precedence over the environment variable.

Getting an API Key:

• Visit developers.quantaroute.com
• Sign up and get your API key
• Use it in the x-api-key header for all API requests

Example Usage in AI Assistants

Once configured, AI assistants (Claude, Cursor AI, etc.) can use tools like:

Example 1: Geocoding

User: "What's the DigiPin for Biswa Bangla Gate, New Town?"

Assistant: [Uses geocode tool]
The DigiPin code for that address is 2TF-39M-JT5F, located at coordinates 22.5788545, 88.4716628.
Full Address: Biswa Bangla Gate, New Town, Biswa Bangla Sarani, Action Area I, New Town, Bidhannagar, North 24 Parganas, West Bengal, 700156, India

Example 2: Location Lookup

User: "What administrative boundaries are at coordinates 28.6139, 77.2090?"

Assistant: [Uses lookup_location_from_coordinates tool]
That location is in:
- Pincode: 110001
- State: Delhi
- Division: New Delhi Central
- Locality: Connaught Place
- District: New Delhi

Example 3: Reverse Geocoding

User: "What's the address for DigiPin 2TF-3FT-J825?"

Assistant: [Uses reverse_geocode tool]
The DigiPin 2TF-3FT-J825 corresponds to:
- Address: FE Block, Sector III, Bidhannagar, North 24 Parganas, West Bengal, 700106, India
- Coordinates: 22.580587°N, 88.419001°E

Troubleshooting

Claude Desktop Issues

1. Server not appearing in Claude Desktop:

   • Verify the config file path is correct for your OS
   • Check that the JSON syntax is valid
   • Restart Claude Desktop completely

2. "Command not found" errors:

   • Ensure Node.js 18+ is installed: node --version
   • Verify npx is available: which npx

3. API authentication errors:

   • Check that QUANTAROUTE_API_KEY is set correctly in the config
   • Verify the API key is valid at https://api.quantaroute.com

Cursor Issues

1. MCP server not loading:

   • Check ~/.cursor/mcp.json exists and has valid JSON
   • Restart Cursor completely
   • Check Cursor's MCP logs for errors

2. Tools not available:

   • Verify the server is running (check Cursor's MCP status)
   • Ensure API key is configured correctly
