Datamuse MCP
Wraps the Datamuse API into ten MCP tools for finding synonyms, antonyms, rhymes, similar-sounding words, and lexical details like definitions, part of speech, syllables, and pronunciation. You can also autocomplete word prefixes, search by spelling patterns with wildcards, or query phonetic similarity. Runs locally over stdio with a five-minute in-memory cache to reduce repeat calls. Useful when you need precise word relationships or linguistic metadata without leaving your assistant workflow, especially for writing, editing, or anything that benefits from real-time vocabulary lookup.
