    ThirdMade agent catalog is surfaced wherever your client lets you attach context. It is context to attach, not an action to run.

    If it does not appear, check that ThirdMade Shelf is connected and that you are looking at its resources rather than its tools.

Custom connectors are a paid-plan feature and take a remote URL only. ChatGPT cannot run a packaged server locally. ChatGPT docs

Same resource, other clients

Read from the server itself, by connecting to it and calling resources/list on 24 September 2026. A listing does not declare its resources, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each resource's type and contents.
