Writing Style Checker MCP Server

A prose linter and AI-slop detector. WSC finds AI tells - words, phrases, and sentence structures overrepresented in AI-generated text, each flag backed by a published corpus study. It also catches classic writing issues: weasel words, passive voice, duplicate words, long sentences, nominalizations, hedging, and filler adverbs. Available as a web editor, HTTP API, MCP server, CLI, and GitHub Action. Its 4 documented tools cluster into check, fix, read & search.

People who work with cloudflare, sveltekit and ai detection and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
