What is supported out of the box
Each Settings page is backed by its shipped catalog — a YAML file in the TrueForge server (linked above) that lists the presets the UI can offer. Catalogs are discovery lists only. Choosing a preset in the UI asks you for credentials (API key, OAuth, and so on); TrueForge stores the configured resource in its database and then they are used in the agent configuration.If you remove an entry from the catalog after configuring it in the UI, it will still be available for selection in the agent configuration.
Changing what the UI offers
If you self-host TrueForge and want a different preset list (add internal MCP servers, trim unused models, ship company skills), point the server at your own YAML files:
When unset, TrueForge uses the catalogs shipped with the server.
