## MCP tools (2)

### `search_words` (~165 tokens)

Search the Jisho.org Japanese<->English dictionary. The keyword can be English (translate to Japanese), Japanese kanji/kana, or romaji. Returns up to `limit` matching dictionary entries, each with the headword (slug), whether it is a common word, JLPT level, all readings/spellings, and English meanings grouped into senses with parts of speech. Use this to translate, look up a kanji/kana word, or find Japanese words for an English concept.

Input parameters:

- `keyword` (string, required): Search term: English word/phrase, Japanese kanji or kana, or romaji (e.g. "house", "家", "いえ", "ie").
- `limit` (number): Maximum number of entries to return (default 10).

### `lookup` (~136 tokens)

Look up a single Japanese or English word in the Jisho.org dictionary and return only the single best/first matching entry in a compact form: headword (slug), common-ness, JLPT level, all readings, a flat list of English meanings, and the unique parts of speech. Best for quick "what does this word mean / how is it read" questions. Accepts kanji, kana, romaji, or English.

Input parameters:

- `word` (string, required): The word to look up: Japanese kanji/kana, romaji, or English (e.g. "食べる", "taberu", "to eat").
