SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Setting up Unity editor automation requires choosing between competing MCP adapters, verifying versions, and avoiding risky unreviewed installs. This Skill inspects your Unity project and proposes exactly one compatible, pinned MCP adapter with full transparency before anything changes. ## Core Features & Use Cases - Project Inspection: Confirms ProjectSettings/ProjectVersion.txt, Unity/Hub availability, OS/architecture, Python or Node requirements, existing MCP servers, and uncommitted files. - Adapter Selection: Defaults to CoplayDev/unity-mcp at an immutable commit, switching to IvanMurzak/Unity-MCP only with documented evidence it meets a requirement the default cannot. - Gated Installation: Generates a plan via pack plan unity, requires the user to repeat a displayed digest verbatim, then applies with pack apply and verifies with pack doctor plus a read-only health check. - Use Case: A developer wants AI-driven Unity editor automation but needs licenses, permissions, backups, and rollback steps reviewed before any server is installed or replaced. ## Quick Start Use the setup-unity skill to inspect this Unity project and propose one compatible pinned MCP adapter with rollback steps, waiting for my confirmation before installing anything.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up a Unity MCP server for editor automation?

Run the doctor inspection first to confirm your Unity version, OS, and existing servers, then generate a plan with `pack plan unity`. Review the downloads, licenses, and rollback steps, repeat the displayed digest to confirm, and apply with `pack apply`.

CoplayDev/unity-mcp vs IvanMurzak/Unity-MCP, which should I use?

CoplayDev/unity-mcp is the default at an immutable commit under the MIT license. Choose IvanMurzak/Unity-MCP only when descriptor or doctor evidence shows it satisfies a stated project requirement the default cannot, and present that evidence.

Can I use an existing local Unity MCP server executable?

Yes, pass `--server-executable` with an absolute path and `--server-sha256` with its hash. Relative paths or hash-mismatched executables are rejected to prevent unverified binaries from being installed.

Does the Unity setup install anything without my confirmation?

No. The skill only proposes a plan and waits for you to repeat the displayed digest verbatim before applying changes. Rollback is always a separately confirmed transaction, and nothing is installed or activated beforehand.

When should I not use the Unity MCP setup skill?

Do not invoke it for version-only or metadata-only questions about a Unity project. In those cases it reads only the requested project metadata and does not create an adapter plan.
