Connect ChatGPT to DropHaul
Add DropHaul as a custom MCP connection in ChatGPT developer mode.
Add DropHaul as a custom MCP connection in ChatGPT developer mode. The connection uses client-managed OAuth, so do not create or paste a personal access token.
Create the app
-
Open Settings → Security and login and turn on Developer mode. Availability can depend on account and workspace policy.
-
Go to Settings → Connectors and select the plus button.
-
Enter a user-facing name and description.
-
Under Connection, enter the exact MCP endpoint, including the
/mcppath:https://majestic-emu-550.convex.site/mcp -
Create the connection. ChatGPT follows the server's OAuth discovery; do not paste a bearer value or client secret into the connection.
-
Complete DropHaul sign-in, choose the company, and review the scopes.
-
Review the tools and metadata discovered from the server.
DropHaul's OAuth metadata advertises refresh support, and a refresh remains bound to the same client, company, user, resource, and narrowed scopes. If ChatGPT cached older discovery metadata, open the connection under Settings → Connectors and select Refresh.
Test the app
- Start a new chat and add the DropHaul connection from the tools menu.
- Run
whoami, then a boundedsearchquery. - Pass one returned result ID to
fetch; do not invent the ID or URL. - Run one role-visible read tool.
- Request a write, inspect ChatGPT's approval prompt and DropHaul's preview, then either reject it or approve that exact operation.
- Disconnect and reconnect; confirm the company and scopes have not widened.
- Revoke consent and verify both the access and refresh paths fail.
Company knowledge can use read-only tools from the server. Eligibility as a
company knowledge source requires the standard search and fetch tool
input schemas plus readOnlyHint: true on the other read-only tools;
DropHaul publishes both. Full operational tools require the developer-mode
connection.
See Security and Troubleshooting. OpenAI's current developer-connection workflow is documented in Connect and test your plugin. Scan Tools is a separate step in the public plugin submission portal, not part of this developer connection.
