Zero Slop MCP server

Zero Slop is a free, open-source helper that finds the telltale wording that makes writing sound machine-made, then guides your AI through a careful edit. It is handy for anyone who drafts with an AI and wants the result to sound like a person wrote it. It also checks that your important details survive the rewrite.

What this MCP server does

You paste a draft into your chat and ask your AI to run it through Zero Slop. Your AI sends the text to the Zero Slop service, which scores it from 0 to 100, where a higher number means more slop patterns. Zero Slop then guides your AI to rewrite the flagged parts without inventing new facts. Before you get the result, it checks that names, numbers, quotations, links and code are still intact. You end up with a shorter, clearer version and a note about what changed.

What you can do with it

• Score a draft and see how sloppy it reads
• Rewrite a paragraph to remove canned openers and hype words
• Check that names, numbers and links survived the edit
• Inspect which phrases were flagged without changing the text
• Compare the edited version against your original
• Teach it a preference by showing an edit you made and why

Try asking your AI

• “Score this launch email and tell me what sounds like AI wrote it”
• “Rewrite this paragraph so it sounds like a person, and keep my numbers the same”
• “Inspect this draft and list the flagged phrases without editing it”
• “Clean up this LinkedIn post and check that my links still work”

What it gives back to you

You get a writing score out of 100, a list of the flagged phrases, and a rewritten version of your text. It also tells you whether the source details like names, numbers and links passed the check. Everything shows up right in the chat, so you can copy the clean version or ask for another pass.
