What it does

Scene Open is an agent skill from IvanMurzak/Unity-MCP. Open a Unity scene asset in Single or Additive mode. Returns the post-open list of all opened scenes. Use 'assets-find' to locate the scene asset first.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Game Development, covering Game development. It works with Model Context Protocol. The repository describes itself as: AI Skills, MCP Tools, and CLI for Unity Engine. Full AI develop and test loop. Use cli for quick setup. Efficient token usage, advanced tools. Any C method may be turned into a… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Game development

Example prompts

  • “assets-find”
  • “/scene-open”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 4c8056f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Scene Open loads about 1.2k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 189 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name
scene-open
description
Open a Unity scene asset in Single or Additive mode. Returns the post-open list of all opened scenes. Use 'assets-find' to locate the scene asset first.

Scene / Open

Open scene from the project asset file. Use 'assets-find' tool to find the scene asset first.

Inputs

  • sceneRef — AssetObjectRef pointing at a SceneAsset. Throws if the asset cannot be resolved or is not a SceneAsset.
  • loadSceneMode (default Single):
    • Single — closes the currently opened scenes and opens this one.
    • Additive — keeps the currently opened scenes and opens this one alongside them.

How to Call

bash
unity-mcp-cli run-tool scene-open --input '{
  "sceneRef": "string_value",
  "loadSceneMode": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

bash
unity-mcp-cli run-tool scene-open --input-file args.json

Or pipe via stdin (recommended):

bash
unity-mcp-cli run-tool scene-open --input-file - <<'EOF'
{"param": "value"}
EOF
Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input
