To connect Ploti to ChatGPT, turn on developer mode, add Ploti as a custom plugin in ChatGPT Plugins, and sign in with your Ploti account. ChatGPT can then look up properties and answer zoning and ordinance questions from the official records Ploti holds for your counties, with the source attached. It can also show maps and tables in the conversation. The connection uses MCP, the standard ChatGPT supports for outside tools.
Follow these steps on chatgpt.com in a web browser. The ChatGPT Mac app has different menus and settings.
Before you start: Your ChatGPT account and workspace must allow developer mode. If the setting is unavailable, check with your workspace administrator. See OpenAI’s connection and testing guide for current requirements.
1

Open ChatGPT in a browser

Visit chatgpt.com and sign in to the account and workspace where you want to connect Ploti. Do the setup and the first test in this browser.
2

Turn on developer mode

On the ChatGPT website, open Settings, select Security and login, and turn on Developer mode. Confirm if ChatGPT asks. If the setting is missing, check that you are on the website and that your workspace allows it.
3

Add the Ploti MCP connection

Open ChatGPT Plugins, select Add, then Create custom MCP server. The New Plugin form asks for a name, description, and Connection details.Name it Ploti, add a description such as U.S. parcel, zoning, and ordinance data, select Server URL under Connection, and enter this public HTTPS endpoint:
MCP server URL
Set Authentication to OAuth. Review the custom MCP server notice, select I understand and want to continue if you agree, then select Create.
If Create plugin opens a conversation with Plugin Creator, return to Plugins. That workflow builds a plugin; this guide connects Ploti’s existing MCP server. Confirm developer mode is enabled before looking for the MCP connection option.
4

Approve the connection

Complete Ploti’s OAuth sign-in in your browser, choose the workspace you want to use, and approve the connection. Leave optional client ID and client secret fields empty.
5

Verify the connection

Return to the Ploti connection in Plugins and check that it lists Ploti’s tools. Fix any connection or sign-in error before starting a chat.
6

Try it in a chat

Start a new chat on the website and add the Ploti MCP connection from the tools menu. Try: Use Ploti to compare parcels between 5 and 20 acres in Winter Garden, Florida, and return a map and table.
