MCP Server IPInfo

This is a version of the MCP Server for IPInfo that implements the complete IPInfo OpenAPI specification with strongly-typed models and comprehensive tool coverage.

Features

• Full OpenAPI Spec Implementation: Complete implementation of IPInfo's OpenAPI specification
• Strongly Typed: All API responses use Pydantic models for type safety
• HTTP Transport: Supports streamable-http transport with health endpoint
• Comprehensive Tools: 25+ MCP tools covering all IPInfo API endpoints
• Built-in Skill Resource: Serves a skill://ipinfo/usage resource that teaches LLMs optimal tool selection and context reuse patterns

Installation

# Using uv (recommended)
uv pip install -e .

# Or with pip
pip install -e .

Configuration

Set your IPInfo API token as an environment variable:

export IPINFO_API_TOKEN=your_token_here

Running the Server

As a standalone MCP server

# Using uv
uv run mcp-ipinfo

# Or with Python
python -m mcp_ipinfo.server

In Claude Code

Add this configuration to your Claude Code settings:

{
  "mcpServers": {
    "ipinfo": {
      "command": "/path/to/.local/bin/uv",
      "args": [
        "--directory",
        "/path/to/mcp-server-ipinfo",
        "run",
        "mcp-ipinfo"
      ],
      "env": {
        "IPINFO_API_TOKEN": "your_ipinfo_api_token_here"
      }
    }
  }
}

Skill Resource

The server includes a built-in skill at skill://ipinfo/usage that guides LLMs on:

• Tool selection: Which tool to use for each intent (general lookup vs. VPN detection vs. WHOIS)
• Context reuse: Carrying IP addresses across follow-up questions
• VPN detection: Using the Plus API (get_plus_ip_info) instead of the Core API for privacy flags

The server's instructions field tells compatible MCP clients to read this resource before using tools. This is also published as a standalone skill at mpak.dev/skills/@nimblebraininc/ipinfo.

Available MCP Tools

Core IP Information

• get_ip_info(ip?) - Get comprehensive IP information
• get_plus_ip_info(ip) - Get full IP intelligence via Plus API (includes privacy detection)
• get_account_info() - Get API account limits and features
• batch_lookup(ips[]) - Batch lookup multiple IPs
• summarize_ips(ips[]) - Get summary statistics for IP list
• map_ips(ips[]) - Create visual map of IP locations

Company & Carrier

• get_company_info(ip) - Get company details for an IP
• get_carrier_info(ip) - Get mobile carrier information

Privacy & Security

• get_plus_ip_info(ip) - Detect VPN, proxy, Tor, relay (via Plus API)
• get_residential_proxy_info(ip) - Detect residential proxy services
• get_abuse_contact(ip) - Get abuse contact information

Network Information

• get_hosted_domains(ip, page?, limit?) - Get domains on an IP
• get_ip_ranges(domain) - Get IP ranges for a domain

WHOIS Lookups

• whois_lookup_by_ip(ip, page?, source?) - WHOIS by IP
• whois_lookup_by_domain(domain, page?, source?) - WHOIS by domain
• whois_lookup_by_asn(asn, page?, source?) - WHOIS by ASN

Single Field Tools

• get_ip_city(ip?) - Get just the city
• get_ip_country(ip?) - Get just the country code
• get_ip_region(ip?) - Get just the region/state
• get_ip_location(ip?) - Get just the coordinates
• get_ip_postal(ip?) - Get just the postal code
• get_ip_timezone(ip?) - Get just the timezone
• get_ip_hostname(ip?) - Get just the hostname
• get_ip_org(ip?) - Get just the organization/ASN

Testing

Run the test client to verify the implementation:

python test_client.py

API Client Usage

You can also use the API client directly in your Python code:

import asyncio
from mcp_ipinfo.api_client import IPInfoClient

async def main():
    async with IPInfoClient() as client:
        # Get current IP info
        info = await client.get_current_info()
        print(f"Current IP: {info.ip}")
        print(f"Location: {info.city}, {info.country}")

        # Get specific IP info
        google = await client.get_info_by_ip("8.8.8.8")
        print(f"Google DNS: {google.org}")

        # Privacy detection via Plus API
        plus_info = await client.get_plus_info("1.1.1.1")
        print(f"VPN detected: {plus_info.anonymous.is_vpn}")
        print(f"ASN: {plus_info.as_info.asn}")

asyncio.run(main())

Type Safety

All models are strongly typed using Pydantic:

from mcp_ipinfo.api_models import (
    FullResponse,      # Basic IP information
    PlusResponse,      # Comprehensive IP intelligence (geo, ASN, privacy)
    CompanyResponse,   # Company information
    RangesResponse,    # IP ranges for a domain
    # ... and many more
)

Requirements

• Python 3.13+
• aiohttp
• fastmcp
• pydantic
• mcp
