IP Judge — Claude Code MCP server: IP checks and setup
Check the IP and network exit seen by an MCP client, look up regional support for AI services, or inspect official service status. Useful when terminal and browser traffic may take different routes.
claude mcp add --transport http ipjudge https://ipjudge.org/mcpWhat IP Judge does
IP Judge connects over Streamable HTTP. Its my_exit tool checks the exit of the machine sending the MCP request; check_ip evaluates an IPv4 or IPv6 address, while ai_availability compares a region with the official support lists for ChatGPT, Claude, Gemini and Muse. service_status retrieves official status for services including Claude, OpenAI, Cursor, GitHub and Cloudflare.
The server is free and needs no key for basic use. Without a key, each visitor can make up to 40 new queries per 10 minutes. Add it to Claude Code with claude mcp add --transport http ipjudge https://ipjudge.org/mcp. A web connector sends requests from the platform’s servers, so my_exit reports their network exit rather than your computer’s.
