Overview

AI-generated overview

Offline MCP server that decodes internet slang, brainrot vocabulary and niche subculture terms for an AI assistant.

What you can do
  • Look up a single term with its meaning, origin, example and vibe
  • Fuzzy-search the lexicon by term, meaning or vibe
  • Scan a caption or tweet and decode every known term in it
  • Pull a random term and show lexicon size with a vibe breakdown
When to use it
Useful when an assistant has to interpret or explain current internet slang, TikTok-era phrasing or underground rap scene vocabulary in messages, captions and posts, and you want that to work without network access.
Requirements
Runs as a local process over stdio, installed from the npm package and started with Node.js after a build step. No accounts, API keys or environment variables are declared, and the lexicon ships with the server so no network access is needed.
Before you install
The lexicon is a fixed, hand-maintained list, so newer slang may be missing until terms are added to the source file and the server is rebuilt. No credentials, writes or third-party data transfer are described.

Installation

In SourceWeft

  1. Open Brainrot Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
