unity-package

name	unity-package
description	Use when installing, removing, inspecting, or refreshing Unity packages.

Package Management

Do not use Unity_RunCommand for package operations. Unity's MCP server exposes first-class package tools that cover every operation in this domain directly.

Routing

Operation	Tool	Typical payload
List installed packages	Unity_PackageManager_GetData	{ "installedOnly": true } (no packageID)
Check a specific package	Unity_PackageManager_GetData	{ "packageID": "com.unity.cinemachine", "installedOnly": true }
List a package's versions	Unity_PackageManager_GetData	{ "packageID": "com.unity.cinemachine", "installedOnly": false }
List a package's dependencies	Unity_PackageManager_GetData	{ "packageID": "com.unity.timeline", "installedOnly": false }
Install a package	Unity_PackageManager_ExecuteAction	{ "action": "Add", "packageID": "com.unity.cinemachine" } (optional version)
Remove a package	Unity_PackageManager_ExecuteAction	{ "action": "Remove", "packageID": "com.unity.splines" }
Refresh / resolve	Unity_PackageManager_ExecuteAction	{ "action": "Resolve" }
Embed a local copy	Unity_PackageManager_ExecuteAction	{ "action": "Embed", "packageID": "com.unity.cinemachine" }
Import a package sample	Unity_PackageManager_ExecuteAction	{ "action": "Sample", "packageID": "...", "sampleName": "..." }

Notes

• Install / remove operations are asynchronous on Unity's side. If the tool returns a "pending" status, poll Unity_PackageManager_GetData with installedOnly: true a few seconds later to observe the final state.
• Package operations can trigger a Domain Reload. Expect transient server unavailability afterward; retry once.
