ChatGPT

Add Dubsado as a custom connector in ChatGPT, then enable it in a chat.

Server URL

https://mcp.dubsado.dev/mcp

Before you start

Adding your own MCP server requires a paid ChatGPT plan, and on some plans it sits behind developer mode. On Business, Enterprise and Edu workspaces an admin may need to allow custom connectors first. OpenAI moves these settings around between releases, so treat the menu names below as a guide and check OpenAI's connector help article if your version looks different.

Steps

Open Settings and find the section for connectors, apps or MCP servers. If there is no option to add your own, look for developer mode in that section's advanced settings and turn it on.
Choose the option to add a custom connector / MCP server.
Name it Dubsado, paste the server URL above, choose the remote or Streamable HTTP transport if you are asked, and leave authentication set to OAuth.
Save, then connect. Sign in to Dubsado in the window that opens, review the consent screen, and choose Approve.
In a chat, open the + / tools menu and turn on the Dubsado connector before asking your question.

ChatGPT shows you each tool call and asks before running it. Every Dubsado tool is read-only, so approving one can only ever read data back into the conversation.

If something goes wrong

The browser window never opens: check that the URL you pasted ends in /mcp and starts with https://.
Approval succeeds but no tools appear: disconnect and reconnect the connector. Tool definitions are fetched fresh on each connection.
"Unauthorized" after it worked before: access was revoked or expired; reconnect from your AI app's connector settings.
An assistant reports partial results: it hit the 120 calls-per-minute limit. Ask again in a minute, or narrow the question.
