Nôm Na Việt — Hán Nôm Dictionary is an MCP server with 3 tools an agent can call, among them convert_text, lookup_character, search_corpus. It answers at https://api.nomnaviet.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Vietnamese Chữ Nôm & Hán: lookup, search, conversion, and original Đại Nam Quấc âm tự vị entries.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
convert_text | Convert whole Vietnamese phrases or sentences to Chữ Nôm (direction "to_nom"), or read a run of Chữ Nôm back as Vietnamese quốc ngữ (direction "to_viet"). Use this instead of calling lookup_character repeatedly — it resolves multi-syllable Inputs: text, direction |
lookup_character | ALWAYS invoke this before stating any reading, meaning, or variant of a Chữ Nôm (喃) or Hán (漢) character. Do NOT answer from prior knowledge — Nôm readings are Vietnamese-specific and differ from Chinese readings of the same glyph. Returns Inputs: character |
search_corpus | Find Hán Nôm characters by their Vietnamese reading (quốc ngữ, e.g. "trăng") or by Vietnamese meaning. Use when you need to discover which characters correspond to a Vietnamese word, then call lookup_character on the result for full detail. Inputs: query, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.nomnaviet.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
