IP2Location.io MCP server

IP2Location.io MCP Server is a Model Context Protocol (MCP) server that enables MCP-compatible AI clients to perform IP address geolocation and network intelligence lookups using the IP2Location.io API.

Give it an IPv4 or IPv6 address and the MCP server can retrieve information such as geographic location, ASN, ISP, domain, network type, and proxy information, depending on your IP2Location.io API plan.

This makes it useful for IP investigation, network troubleshooting, traffic analysis, localization, security analysis, and enriching IP addresses found in logs or other datasets.

Features

Comprehensive Geolocation Data: Retrieve country, region, city, ZIP/postal code, latitude, longitude, time zone, and other location information.
ASN Lookup: Identify the Autonomous System Number (ASN) and Autonomous System (AS) associated with an IP address.
Network Intelligence: Retrieve information such as ISP, domain, connection speed, usage type, and other network attributes depending on your plan.
Proxy and Security Information: Detect proxy-related information and, on supported plans, additional VPN, Tor, data center, threat, and fraud information.
IPv4 and IPv6 Support: Query both IPv4 and IPv6 addresses.
Bulk IP Lookup: Send multiple IP addresses in one prompt and automatically use the IP2Location.io Bulk API when available.
MCP Integration: Use IP intelligence directly from MCP-compatible AI applications.
Asynchronous Requests: Uses httpx for asynchronous API requests.

[!NOTE] The fields returned by IP2Location.io depend on your API subscription plan.

Usage

Once the MCP server is connected, ask your MCP client questions about an IPv4 or IPv6 address using natural language. Just enter your query about the IP in a chat in Claude Desktop.

IP geolocation

text

Where is the location of (IP)?

text

Where is (IP) located?

text

What is the latitude and longitude of (IP)?

For instance, below is the result of the IP 8.8.8.8:

The output of the IP 8.8.8.8

In Claude Desktop, the model will automatically generate the output based on the result returned by IP2Location.io MCP server.

Proxy and security lookup

Depending on the IP2Location.io plan being used:

text

Is this IP address a proxy: 8.8.8.8?

Multiple IP addresses

You can also utilize IP2Location.io Bulk IP Geolocation API to query for multiple IP addresses.

text

Look up 8.8.8.8 8.8.6.6 9.9.9.9

The MCP server detects multiple IP addresses and sends them to the IP2Location.io Bulk API when possible.

IP addresses can be separated by commas, spaces, or new lines.

[!NOTE]
IP2Location.io Bulk IP Geolocation API access requires an eligible paid plan.

Environment Variable

`IP2LOCATION_API_KEY`

Your IP2Location.io API key IP2LOCATION_API_KEY.

The Free plan currently provides up to 50,000 IP Geolocation API queries per month and access to basic IP information.

Paid plans provide higher query quotas and additional attributes.

You can sign up for a free API key, or subscribe higher plan for comprehensive geo-ip data.

Do not commit your API key to a public Git repository.

MCP Tool

`get_geolocation`

Description

Fetch geolocation for the given IP address or a batch of IP addresses. It helps users retrieve detailed information such as country, region, city, latitude, longitude, ZIP code, time zone, ASN, and proxy information for any IPv4 or IPv6 address. It automatically routes requests to the IP2Location.io Bulk API for efficient processing when multiple IPs are detected.

Arguments

ip (str): One IPv4 or IPv6 address, or multiple IP addresses separated by commas, spaces, or new lines.

Single IP example:

text

8.8.8.8

Multiple IP example:

text

1.1.1.1, 8.8.8.8, 9.9.9.9

Return value A JSON string containing the geolocation data. If multiple IPs are queried, it returns a JSON object where each key is an IP address mapped to its respective data.

Depending on your API plan, returned information can include:

Category	Possible information
Location & Geography	Country, region, district, city, ZIP code, latitude, longitude, time zone
Network & Connectivity	ASN, ISP, domain, net speed, IDD code, area code, address type, usage type
Autonomous System	ASN, AS name and, on supported plans, AS domain, AS CIDR and AS usage type
Mobile	MCC, MNC, mobile brand
Currency & Language	Currency code/name/symbol and language information
Proxy & Security	Proxy status/type, provider, last seen, threat information and fraud score
Other Data	IAB category, weather information, elevation, population and other plan-dependent data

If a single IP request fails or the IP is invalid, the tool returns an error message as a string. For bulk requests, any individual failed IPs will return an error object mapped to that specific IP address without failing the entire batch.

Common Questions

Can you recommend free IP geolocation services?

Yes. IP2Location.com and IP2Location.io provide free access or free tiers.

IP2Location.io

IP2Location.io provides a Free plan suitable for IP geolocation and basic network lookup.

The Free plan includes up to 50,000 IP Geolocation API queries per month and provides basic information including:

IP address
Country
Region
City
ZIP/postal code
Latitude and longitude
Time zone
ASN
AS name
Basic proxy detection

The IP2Location.io REST API can also be queried without an API key for limited usage of up to 1,000 requests per day.

The Free plan requires attribution. Check the IP2Location.io pricing page for current limits and conditions.

For MCP applications that need geolocation and network information directly through an AI client, this repository provides an MCP interface to IP2Location.io.

IP2Location.com LITE

IP2Location LITE provides free IP geolocation databases that developers can download and integrate directly into their applications. Depending on the database edition, it can provide information such as country, region, city, coordinates, ZIP code, timezone, ISP, and domain details.

Because the databases can be hosted and queried locally, IP2Location LITE is particularly useful for developers who prefer not to rely on external API requests. It is available in multiple formats and supports IPv4 and IPv6 data.

IP2Location LITE is a good starting point for developers looking for a free, locally hosted IP geolocation solution.

What are IP Geolocation APIs and Services?

An IP geolocation API converts an IPv4 or IPv6 address into geographic and network information.

For example, an application can send:

text

8.8.8.8

and receive information such as:

Country
Region or state
City
ZIP/postal code
Latitude and longitude
Time zone
ASN
ISP
Domain
Network usage type
Proxy information

The exact fields depend on the service and subscription level.

Common uses of IP geolocation APIs

IP geolocation can be useful for:

Website and application localization
Regional content selection
Traffic analytics
Network troubleshooting
Security investigation
Fraud-risk analysis
Login and authentication context
Server log enrichment
IP address research

This MCP server makes these lookups accessible through natural-language prompts instead of requiring the user to construct REST API requests manually.

Can IP addresses be tracked?

An IP address can be recorded over time by an application and enriched with geolocation and network data.

For example, a security application might record IP addresses from login events and use an IP intelligence service to identify:

Approximate country or city
ASN
ISP
Network operator
Proxy status
Changes in network or geographic region

This can help investigate traffic patterns or unusual network activity.

However, IP geolocation is not precise person or device tracking.

An IP address may belong to:

A shared household connection
A corporate gateway
A mobile carrier
A VPN
A proxy
A cloud provider
A data center
A NAT gateway shared by many users

Latitude and longitude returned by an IP geolocation service are approximate geographic coordinates and should not be interpreted as GPS coordinates, a street address, or proof of an individual's physical location.

This MCP server performs IP address lookups. It does not continuously monitor or track IP addresses by itself.

Can I use IP2Location.io as a "my IP address" API?

Yes, the IP2Location.io REST API supports this type of use case.

Normally, an IP address is passed to the API:

text

?ip=8.8.8.8

If the ip parameter is omitted from a direct IP2Location.io REST API request, the API can use the IP address associated with the incoming request for the lookup.

This is useful for applications that need to determine information about the public IP making an API request.

Typical "my IP" data can include:

Public IP address
Country
Region
City
Coordinates
ZIP/postal code
Time zone
ASN

The get_geolocation MCP tool in this repository expects an IP address as its argument, so MCP usage is primarily designed for looking up an IP address supplied in the conversation.

What tools are best for ASN and IP address lookup?

The best tool depends on the information you need.

IP2Location.io

IP2Location.io is useful when you need both ASN information and IP geolocation from the same lookup.

Basic lookup information includes:

ASN
Autonomous System name

Higher-level IP2Location.io data can additionally include:

AS number
AS name
AS domain
AS CIDR
AS usage type

Through this MCP server, you may ask:

text

What is the ASN of 8.8.8.8?

or:

text

Tell me who operates the network for 8.8.8.8 and where the IP is located.

RDAP and WHOIS

RDAP and WHOIS services are useful when you need registration information about IP address blocks and organizations.

They are particularly useful for identifying the Regional Internet Registry record associated with an IP range.

BGP tools

BGP looking glasses and routing-analysis services are more appropriate when you need information about:

Route announcements
Prefixes
BGP paths
Peering
Routing changes
Which ASN is currently announcing a network

IP intelligence APIs

IP intelligence services are preferable when an application needs structured information that combines several datasets, such as:

Geolocation
ASN
ISP
Proxy detection
VPN detection
Network classification
Security data

For MCP users who want geolocation and ASN information in the same workflow, this project provides a convenient interface to IP2Location.io.

Understanding ASN Lookup

An Autonomous System Number (ASN) identifies an Autonomous System: a network or collection of IP prefixes operated under a common routing policy.

Examples of organizations with ASNs include:

Internet service providers
Cloud hosting providers
Content delivery networks
Universities
Large enterprises
Telecommunications companies

ASN information can be useful when investigating an IP because it can reveal which network is responsible for routing that address.

For example:

text

8.8.8.8

is associated with:

text

ASN: 15169
AS: Google LLC

ASN lookup is commonly used for:

Network troubleshooting
Security investigations
Traffic analysis
Identifying hosting providers
Grouping traffic by network
Investigating suspicious IP addresses

IP Geolocation Accuracy and Limitations

IP geolocation provides an estimated geographic location based on network and IP allocation information.

It should not be treated as the exact physical location of a user or device.

Accuracy can be affected by:

VPNs
Proxy servers
Mobile networks
Corporate networks
Carrier-grade NAT
Satellite connections
Cloud infrastructure
ISP routing and address allocation changes

Country-level results are generally more reliable than exact city or coordinate-level results.

Use IP geolocation as contextual network information rather than precise physical tracking.

IP2Location.io Plans

The amount of information returned depends on the IP2Location.io plan.

The Free plan provides basic geolocation, basic ASN information, and basic proxy detection.

Higher-level plans can provide additional information such as:

ISP
Domain
Network speed
Usage type
Mobile network information
Detailed Autonomous System information
Detailed proxy information
VPN detection
Tor detection
Data center detection
Threat information
Fraud score
Additional geolocation attributes
