For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool package-search --input-file args.json
Or pipe via stdin (recommended):
unity-mcp-cli run-tool package-search --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
`query`	`string`	Yes	The package id, name, or description. Can be: Full package id 'com.unity.textmeshpro', Full package name 'TextMesh Pro', Partial name 'TextMesh' (will search in Unity registry and installed packages), Description keyword 'rendering' (searches in package descriptions).
`maxResults`	`integer`	No	Maximum number of results to return. Default: 10
`offlineMode`	`boolean`	No	Whether to perform the search in offline mode (uses cached registry data only). Default: true. Set to false to fetch latest exact matches from Unity registry.
