Zero Slop — Claude Code MCP server: what it does, how to install
Rates drafts on a 0 to 100 scale and strips robotic buzzwords while keeping numbers, quotes, and facts intact.
claude mcp add --transport http zero-slop https://mcp.zero-slop.ai/mcpWhat Zero Slop does
Zero Slop detects formulaic AI text patterns using 294 weighted rules alongside a 96-entry lexicon. It catches canned corporate openers, inflated claims of significance, and binary contrasts without altering the core point.
The editorial cycle follows eight distinct stages. The engine evaluates pacing, rewrites repetitive stock phrasing, and passes the output through a dedicated verification step. Links, numbers, code blocks, and names stay protected against hallucinated edits.
Connecting through the remote MCP setup routes your calls to https://mcp.zero-slop.ai/mcp. To prevent automatic update checks against the public GitHub Releases API, set the environment flag ZS_NO_UPDATE_CHECK=1.
What it helps with
- remove formulaic AI buzzwords from product announcements
- score writing quality and repetition on a 0 to 100 scale
- protect numbers, citations, and URLs during automated rewrites
- flag hollow openers and unearned declarations of importance
