Audit a YouTube script from inside your assistant

In ChatGPT: install the plugin

Prepublish is a listed ChatGPT plugin, so there is nothing to configure. Open Plugins in the ChatGPT sidebar, search for Prepublish, and select Install plugin. No sign-in is asked for. It works on the web, desktop and mobile apps, on every ChatGPT plan that can install plugins.

Once installed, ask for an audit in plain words or mention @Prepublish. The full audit renders inline as a report card: scores, the relative attention-risk map, the flagged passages and the first rewrite. Install from the directory rather than asking the chat to find the plugin: in-conversation plugin search is unreliable for recently listed plugins. Step by step: Prepublish in ChatGPT.

Everywhere else: connect the endpoint

One URL, Streamable HTTP, stateless. Paste it wherever your client asks for a remote MCP server.https://prepublish.ai/mcp is the same server and keeps working, so anything already configured stays connected.

https://mcp.prepublish.ai

{
  "mcpServers": {
    "prepublish": {
      "command": "npx",
      "args": ["-y", "prepublish-mcp"]
    }
  }
}

Step by step per client: Claude Desktop, ChatGPT, Cursor, and Cline. The Claude Code hub covers the shared reference: every client, the six tools and the limits.

Connect with an API key

Optional. Anonymous calls work, but they carry no account, so they share the endpoint’s daily allowance with every other anonymous caller. Create a key at prepublish.ai/dashboard and send it as a bearer token on every call. The key is shown once, when it is created, and can be revoked from the same page afterwards.

{
  "mcpServers": {
    "prepublish": {
      "type": "http",
      "url": "https://mcp.prepublish.ai",
      "headers": { "Authorization": "Bearer pp_live_REPLACE_WITH_YOUR_KEY" }
    }
  }
}

• Anonymous. Counted against the shared daily cap on AI-backed calls, and against a per-connection allowance of 6 calls per 10 minutes.
• With a key. Attributed to your account, not charged against the shared daily cap, and allowed 30 calls per 10 minutes on that connection. Your account’s own plan quota is the limit that applies.

Those are the defaults and they are published live in the server card. Muse (muse.ai/platform) stores the key in its Secure Credentials Store and sends it on every call, so nothing has to be pasted into a prompt.

The six tools

Try it without a client

The endpoint answers plain JSON-RPC over POST, and a bare GET returns a machine-readable server card.

curl -s https://mcp.prepublish.ai \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
       "params":{"name":"script_runtime","arguments":{"target_minutes":10}}}'

What it will not do

• It does not predict published retention. Every check reads text only. It maps relative attention risk inside an unrecorded draft; it cannot account for delivery, editing, thumbnail, topic or distribution, and no result is a forecast of what viewers will do.
• It does not decide monetisation. The policy pre-flight reads your script against YouTube’s published guidelines and links the official page for each category. Only YouTube decides, and it decides on the finished video.
• It does not write your script. These tools audit a draft you already wrote. If you want one generated, use a writing tool and bring the draft back here.
• It does not invent an email address. An address is optional on a free full audit: give one and the result link is emailed to you as well, leave it out and the audit still runs. On a connection authenticated with an API key your account address is used.
