Add the server

  1. Open Plugins

    Go to chatgpt.com/plugins, select the plus button and choose Add custom MCP server.

  2. Enter the server

    Enter a name and a description. Under Connection, enter the URL as a public endpoint:

    https://mcp.ultimo-bots.com/mcp

  3. Set the sign-in

    Set the authentication to OAuth, review the warning, select I understand and want to continue and then Create as a plugin.

  4. Approve on the consent page

    A browser tab opens in the Ultimo Bots portal. Sign in, and the page Connect an AI assistant opens. Choose the Workspace. Every permission the client asks for starts ticked, so untick what you do not want to give, or use Clear all and tick only what you need. Agent access starts on All agents in this workspace, including future agents; switch to Only selected agents if you prefer. Then click Allow connection.

  5. Try it

    In a chat, ask: “List my Ultimo Bots agents.” When the tool list looks out of date, Refresh on the plugin updates it.

Which plans may add custom MCP servers is set by OpenAI, and account and workspace policies apply. Steps from OpenAI's guide (read November 8, 2026). Codex has its own setup.

What ChatGPT can do

ChatGPT gets the tools for your daily work: agents and their business context, knowledge, conversations, leads, insights and the Success Score, widget, channels, live chat settings, reports and notifications.

Plans, invoices and credit purchases, your account and team, bulk exports, messages to individual visitors and stored API credentials stay in the Ultimo Bots portal when you use ChatGPT. What ChatGPT receives is listed in the privacy policy.

What to ask ChatGPT

  • “Summarize this week's conversations and group the questions by topic.”
  • “Which new leads came in since Monday?”
  • “Add this page to my agent's knowledge and tell me when it is ready.”

To give your agent new abilities, such as booking or checking live stock in your own system, describe the job to Mo in the AI Studio. A worked example is in the post ChatGPT MCP for your AI agent, both ways.

Change or remove the connection

In the Ultimo Bots portal, open MCP connections in the sidebar next to Agents and Workspaces. Revoke access ends a connection at once.
