| 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
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:
unity-mcp-cli run-tool unity-tool-list --input-file args.json
Or pipe via stdin (recommended):
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.
