For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool package-list --input-file args.json
Or pipe via stdin (recommended):
unity-mcp-cli run-tool package-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.

Input

Name	Type	Required	Description
`sourceFilter`	`string`	No	Filter packages by source.
`nameFilter`	`string`	No	Filter packages by name, display name, or description (case-insensitive). Results are prioritized: exact name match, exact display name match, name substring, display name substring, description substring.
`directDependenciesOnly`	`boolean`	No	Include only direct dependencies (packages in manifest.json). If false, includes all resolved packages. Default: false
