Decodes internet slang, brainrot vocabulary, and niche subculture terms. 100% offline, the lexicon ships with the server. Includes the classic brainrot (skibidi, sigma, rizz, fanum tax, ohio, mogging...) plus the underground rap scene (Nettspend, Xavier Wulf era, Osamason, KanKan, LazerDim700, plugg, rage...) and the TikTok era.

search_terms, fuzzy search by term, meaning, or vibe
decode_text, scan a caption/tweet and decode every known term in it

Limits and privacy

This project is intentionally narrow. It should be treated as a practical helper, not a complete certification or security audit. Check the implementation and the returned data before using it with sensitive material. No credentials are required unless the project explicitly says otherwise.

Try it

After building, connect the server through your MCP client. The repository root also contains smoke-test.mjs for projects covered by the shared harness. A typical tool call starts with decode_term.
