How to connect Leni to ChatGPT

Connect Leni to ChatGPT through Model Context Protocol, or MCP, to use your authorized Leni context and tools in a conversation. You need a Leni account and permission to add a custom MCP server in your ChatGPT workspace.

Add the Leni server

1. In ChatGPT on the web, open Plugins. Select the plus button, then Add custom MCP server.
2. Name it Leni and enter https://mcp.leni.co/mcp as the server URL.
3. Select OAuth authentication. Use the server's supported discovery and client-registration flow, then sign in with the Leni account connected to your organization.
4. Review the permissions and risk notice, create the plugin and install it.

Use Leni in a conversation

Start a chat, type @ and select Leni. Try: "Use Leni to summarize the context I can access for my current property analysis, and identify the sources."

Your Leni account and approved permissions determine the data and actions available. Review an action before approving it.

If you cannot add or connect it

Ask your workspace administrator about custom MCP permissions. If authorization expires or your access changes, reconnect with the correct Leni account. For setup help, contact info@leni.co.
