Overview

AI-generated overview

Remote MCP server that geolocates IP addresses, returning country, city, ISP, ASN and VPN/proxy/Tor flags, paid per call via x402.

What you can do
Look up a single IP address and get country, region, city, coordinates, timezone, ISP, ASN and VPN/proxy/Tor flags as JSON. Look up up to 20 IP addresses in one batch call and get an array of results. Supports both IPv4 and IPv6 addresses.
When to use it
Useful for fraud screening, bot detection, region-based access control, content localization, or enriching logs and analytics with location and network data for IP addresses. The batch tool suits bulk log analysis and multi-address screening. It does not cover domain or DNS data.
Requirements
Remote SSE endpoint; no API key or signup. A client that can handle x402 payment challenges is needed, with a funded wallet holding USDC on Base L2 (eip155:8453). Network access to the endpoint.
Before you install
Each call costs money: $0.008 per single lookup and $0.02 per batch of up to 20, paid in USDC on Base L2 through x402, so an x402-capable wallet or client is needed and spending happens without a signup step. Looked-up IP addresses are sent to a third-party service.

Installation

In SourceWeft

  1. Open IP Geolocation API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fip-geolocation/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

IP Geolocation API

[MCP Server] [x402] [License: MIT]

Geolocate any IP address -- country, city, ISP, ASN, VPN/proxy/Tor detection. IPv4 and IPv6 support. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "ip-geolocation": {      "url": "https://ip-geolocation.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl "https://ip-geolocation.api.klymax402.com/api/lookup?ip=..."# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

ip_lookup_geolocation

Use this when you need to geolocate an IP address. Returns full location and network data in JSON.

Parameters

NameTypeRequiredDescription
ipstringyesIP address to lookup (e.g. 8.8.8.8)

Example response:

json
{"ip":"8.8.8.8","country":"United States","countryCode":"US","region":"California","city":"Mountain View","latitude":37.386,"longitude":-122.084,"timezone":"America/Los_Angeles","isp":"Google LLC","asn":"AS15169","isVPN":false,"isProxy":false,"isTor":false}

When to use: fraud detection, content localization, access control by region, analytics enrichment, and bot detection.

Not for: domain data (use domain_lookup_intelligence), DNS records (use network_lookup_dns).

ip_lookup_geolocation_batch

Use this when you need to geolocate multiple IP addresses at once (up to 20). Returns an array of geolocation results in JSON.

Parameters

NameTypeRequiredDescription
ipsarrayyesArray of IP addresses to lookup (max 20)

Example response:

json
{"results":[{"ip":"8.8.8.8","country":"United States","city":"Mountain View","isp":"Google LLC","isVPN":false},{"ip":"1.1.1.1","country":"Australia","city":"Sydney","isp":"Cloudflare","isVPN":false}],"total":2}

When to use: bulk log analysis, batch fraud screening, and enriching analytics data with location info. More cost-effective than single lookups.

Not for: single IPs (use ip_lookup_geolocation), domain data (use domain_lookup_intelligence).

Example agent prompts

  • "Geolocate an IP address"
  • "Geolocate multiple IP addresses at once (up to 20)"

Payment

  • Protocol: x402 -- HTTP-native pay-per-call, no signup, no API key

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
