There are some major benefits for converting read-only tool calls into resources:

• Better performance as there are less tools in the context
• Better UX as users can select resources relevant to the context
• LLMs can discover resources on their own w/o having to make a tool call, so potentially faster
• Good MCP hosts cache the resources, so it's faster
• Actually follows the protocol

This seems like the ideal way to encode data for models. Here are some things we should add:

• Scene hierarchy, we should make a compact representation of the game objects in a scene for the models
• Serialized game objects. Right now we do searching and the like, but we should get a game object with instance ID or path as a resource
• Logs, instead of a tool call it could be a resource as well
• Packages
• Menu items (I recently made this a tool call, it should be a resource)
• Tests
• Editor state (read only items in manage_editor)
• Tags
• Layers

What else could be added?
