Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

execFileSync(ffmpeg, ['-hide_banner', '-loglevel', 'error', '-y', '-i', resolve(input),
Touches key and credential files integrations/github-action/review.mjs:13
    npm_config_userconfig: join(directory, "user.npmrc"),

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

deslop
deslop
Rewrite a pasted draft with one bounded AI editorial response plus local scoring and source checks. Returns the safest source-preserving edit and exact before and after writing scores. If a writing target is missed, the edit still comes back with a clear review warning. Use it to improve writing quality, never to hide authorship or evade a disclosure requirement. Try and MCP use our hosted Zero Slop agent harness; results and speed may differ across Codex, Claude Code, Cowork, ChatGPT Work, and other hosts or skills.

Zero Slop — questions

Answers built from our own checks of this server.

What can Zero Slop do?
It exposes 1 tools, read directly from the server on our last check. Among them: deslop. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Zero Slop working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 84 of 91 checks got a reply (92.3%), average response time 296 ms. The bar chart above shows every period we have measured.
How do I connect Zero Slop?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Zero Slop need an API key?
No. Zero Slop completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Zero Slop?
It answers our handshake in 296 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Zero Slop open source?
Yes — it is published under the MIT licence, written in Python and 122 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
