Add, remove and link components

[Doidel]

My ClaudeCode tells me that it can't link components with each other in the scene hierarchy. Is that true?

This is a Unity MCP limitation - it can see the properties but can't set component references. This is a known
issue with serialized Unity Object references.

Also, I run into several issues when the MCP should add or remove components, be it from GameObjects in the scene, from prefabs, or in other scenarios. It just compiles a list for me what I have to do manually. Am I doing something wrong or is this a known limitation, as Claude Code tells me?

Still, I'm already getting a lot of value from this MCP, so thanks!

Same I’m encountering an issue where the tool can’t add scripts to my objects.
It returns the following error:
"success": false,
"code": "Target GameObject ('-5968') not found using method 'default'.",
"error": "Target GameObject ('-5968') not found using method 'default'."
-5968 is instance id of the object it tries to add component
It seems the system is unable to attach the script to the Player object automatically due to Unity API limitations in this environment.
I’m using Unity 6.2 & i test it with Vscode Copilot
Also, when I asked it to run an editor tool that the AI wrote, it kept executing it multiple times instead of recognizing that it had already been run.

Thanks @Doidel @Altaiar, that's true. I think we have manage_gameobject tool, which does a little bit too much 😅. It can probably be separated to great effect
