About the project

Unity-MCP connects AI coding agents to the Unity game engine through MCP, letting them work with the Unity Editor and running games. It is used by game developers to generate code, automate development and testing, debug projects, and add AI-driven behavior to games. The catalogue entries provide skills, instructions, an MCP integration, and settings for operating this workflow.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

unity-skill-generate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Skill (Tool) / Generate All

Generate all skills from the existed Tools in the Unity Project.

Inputs

  • path (optional) — project-relative skills folder (e.g. .claude/skills). Absolute paths and .. traversal segments are rejected. When null/empty, the editor's configured SkillsRootFolderAbsolutePath is used.

Behavior

Creates the destination folder if missing, then invokes McpPluginInstance.GenerateSkillFiles(...) to emit a SKILL.md per registered MCP tool. The plugin's SkillsPath is temporarily swapped to the target folder and restored in finally so the on-disk configuration is unchanged after the call returns.

How to Call

unity-mcp-cli run-system-tool unity-skill-generate --input '{
  "path": "string_value"
}'

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

unity-mcp-cli run-system-tool unity-skill-generate --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-system-tool unity-skill-generate --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

Name Type Required Description
path string No Path to the skills folder. If null or empty, the default path will be used.

Input JSON Schema

{
  "type": "object",
  "properties": {
    "path": {
      "type": "string"
    }
  }
}

Output

This tool does not return structured output.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
