What it does

Unity Tool List is an agent skill from IvanMurzak/Unity-MCP. List all Unity-MCP tools registered in the connected Unity Editor instance. Optional regex filter matches against tool name, description, and argument names/descriptions. Use the includeDescription / includeInputs toggles to control the response size.

Its SKILL.md is about 1.1k 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 and MCP servers. It works with Unity and 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
  • Tasks that involve MCP servers

Example prompts

  • “/unity-tool-list”

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

Unity Tool List loads about 1.1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 201 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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
unity-tool-list
description
List all Unity-MCP tools registered in the connected Unity Editor instance. Optional regex filter matches against tool name, description, and argument names/descriptions. Use the `includeDescription` / `includeInputs` toggles to control the response size.

Tool / List

List all Unity-MCP tools registered in the connected Unity Editor instance. Optionally filter by regex across tool names, descriptions, and arguments.

Inputs

  • regexSearch (optional) — case-insensitive regex with a 200ms execution-timeout guard. Invalid regex throws an ArgumentException. Matches name → description → input names → input descriptions.
  • includeDescription (default false) — populate each tool's Description field.
  • includeInputs (default None) — one of None, Inputs (names only), InputsWithDescription (names + descriptions).

Behavior

Iterates UnityMcpPluginEditor.Instance.Tools.GetAllTools(), evaluates the filter (if any), and projects each surviving tool into a ToolInfoData honoring the verbosity toggles.

How to Call

bash
unity-mcp-cli run-tool unity-tool-list --input '{
  "regexSearch": "string_value",
  "includeDescription": "string_value",
  "includeInputs": "string_value"
}'

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

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

Or pipe via stdin (recommended):

bash
unity-mcp-cli run-tool unity-tool-list --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.
