Use it from Claude (MCP / CLI)

The endpoint is a plain HTTP GET, so you can call it directly from Claude Code, a shell script, or any HTTP client. A minimal one-liner you can drop into a script or an MCP tool:

# shell
name="Caroline"
curl -s "https://myhangulname.com/api/v1/transliterate?name=$name" | jq -r '.variants[0].options[0]'
# → 캐롤라인

To expose it as a native Claude tool, wrap this call in a small MCP server (transliterate_name(name, lang)) that fetches the URL above and returns the JSON — then register it with claude mcp add.

• Results are cached, so repeat lookups are instant.
• Transliteration has no single right answer; the first option is the most recommended.
