Use it in Claude (MCP)

A hosted Model Context Protocol server exposes a transliterate_name tool, so Claude and other agents can convert names natively — no wrapper needed.

# Claude Code
claude mcp add --transport http my-hangul-name https://www.myhangulname.com/api/mcp

Or add https://www.myhangulname.com/api/mcp as a custom connector in Claude Desktop / claude.ai. Prefer plain HTTP? The GET endpoint above works from any client or shell script too.

Notes

• Results are cached, so repeat lookups are instant.
• Transliteration has no single right answer; the first option is the most recommended.
• Already-Hangul input is returned unchanged.
• Free for personal and commercial use. Built by Wehome.
