Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

convert
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 compounds as units, which per-character lookup cannot do. Handles both old-style and new-style tone placement (hòa / hoà). Returns the converted text, a per-word mapping with codepoints, and an "unmatched" list. Words in "unmatched" have NO entry in the dictionary. Say so — never substitute a character that looks plausible. Input is truncated past 120 characters.
corpus
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. Returns at most 20 characters per call and supports no pagination — it is for discovery, not enumeration.
lookup
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 data that cannot be inferred: Hán-Việt and Nôm readings, dị thể (variant) characters with their codepoints, IDS decomposition and Kangxi radical, Middle-Chinese fanqie, and Vietnamese meanings. Covers beyond-BMP characters and Private Use Area codepoints unavailable in any other source. Use for Vietnamese Hán Nôm. Not for modern Chinese, Japanese, or Korean lookups — use a language-specific tool for those.

Is Nôm Na Việt — Hán Nôm Dictionary working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 471 ms. The bar chart above shows every period we have measured.
Is Nôm Na Việt — Hán Nôm Dictionary still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Nôm Na Việt — Hán Nôm Dictionary?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Nôm Na Việt — Hán Nôm Dictionary need an API key?
No. Nôm Na Việt — Hán Nôm Dictionary completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Nôm Na Việt — Hán Nôm Dictionary?
It answers our handshake in 471 ms on average, which is faster than 25% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
