ChatGPT
- On a computer, open chatgpt.com/plugins.
- Select +, then Add custom MCP server.
- Name it Nipto, add a short description, and under Connection enter
https://nipto.app/mcp. - Keep the sign-in with OAuth, confirm the warning with I understand and want to continue, then select Create as a plugin.
- Install the plugin, sign in to Nipto and select Allow (see Signing in).
- In a new conversation, type @ and pick Nipto.
Adding your own server is a newer, web-only ChatGPT feature and depends on your plan. In a work or school account, an admin may have to allow it. If you do not see Add custom MCP server, your account does not offer it yet.
