Install a package from the Unity Package Manager registry, Git URL, or local path. This operation modifies the project's manifest.json and triggers package resolution. Note: Package installation may trigger a domain reload. The result will be sent after the reload completes. Use 'package-search' tool to search for packages and 'package-list' to list installed packages.
unity-mcp-cli run-tool package-add --input '{
"packageId": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool package-add --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool package-add --input-file - <<'EOF' {"param": "value"} EOF
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.
