unity-tool-list

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

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.
