01What it is and who is there
OpenAI's developer documentation describes publishing plugins to the "ChatGPT Directory," with a public review for remote MCP servers and optional UI. A listed plugin lets ChatGPT users use your product inside their conversations. The directory is young, the rules are still evolving, and you need to build a plugin before you can list.
02Cost and what you actually pay for
No listing fee was found in the documentation checked. Your cost is building the plugin or MCP server, passing review and keeping it working. Check current terms.
03Is it right for you?
It fits products with an API that answers questions or takes actions people would ask an assistant for, such as search, booking, data lookup or content creation. It fits poorly for products with no API. If your API is unstable, wait.
04Before you start
- Read the Apps SDK documentation, the plugin guidelines and the review requirements on developers.openai.com.
- A remote MCP server or plugin, with authentication that protects users' data.
- A privacy policy and support contact.
05Step-by-step: how to distribute here
- Build the plugin using the Apps SDK or an MCP server, following the docs.
- Test it with real prompts users would type.
- Prepare the server for public review, as the documentation describes.
- Submit it to the directory and fix any review findings.
- Tell your users how to find and enable it.
- Keep it updated as the platform changes.
06What to post or submit
Plugin description:
[Product] in ChatGPT: ask it to [action], e.g. "[example prompt]". Requires a [product] account: [yes/no].07Common mistakes and do-nots
- Do not request access to data you do not need.
- Do not let actions run without user confirmation where the guidelines require it.
- Do not assume the rules are stable; recheck before each update.
08How to measure it
- Track plugin usage and sign-ups from ChatGPT.
- Track support questions about the plugin.
- A realistic test: two to three months after listing.
09Time budget
- Before: 20 to 60 hours.
- Ongoing: 2 to 4 hours a month.
10Pair it with
- MCP and AI assistant directories — other MCP listings.
- AI-assistant visibility — be recommended in answers.
- Documentation, guides and tutorials — clear docs for setup.
- Build in public on X — share demos.
