Registry Browser MCP

MCP (Model Context Protocol) integration for Registry Browser. Exposes Registry Browser operations — embed, de-embed, publish, and create packages — as MCP tools, enabling AI agents and IDE integrations to manage Unity packages programmatically.

Installation

Via Git URL

Open Window → Package Manager, click +, and choose Add package from git URL.

To install the latest version:

https://github.com/Warlander/registry-browser-mcp.git

Related MCP server: Unity MCP Server

Via Scoped Registry

Add the Warlogic registry to your Packages/manifest.json:

{
  "scopedRegistries": [
    {
      "name": "Warlogic",
      "url": "https://upm.maciejcyranowicz.com",
      "scopes": ["com.warlogic"]
    }
  ],
  "dependencies": {
    "com.warlogic.registrybrowser.mcp": "2.0.0"
  }
}

Then open Window > Package Manager and look for com.warlogic.registrybrowser.mcp.

Prerequisites

• com.unity.ai.assistant — the official Unity AI Assistant package, which provides the Unity MCP framework this package integrates with.

• com.warlogic.registrybrowser — the Registry Browser tool whose operations are exposed via MCP.

Setup

1. Ensure com.unity.ai.assistant and com.warlogic.registrybrowser are installed in your project.

2. Install this package. The manage_registry_browser MCP tool is automatically discovered and registered by Unity's MCP tool registry.

Usage

Once installed, the following MCP tool becomes available to any connected MCP client (e.g., AI assistants, IDE integrations):

• manage_registry_browser — performs Registry Browser operations programmatically.

  • status — list configured registries and installed packages with their versions and embed status.

  • embed — clone a package repository into Packages/Embeds/ at a specific commit.

  • de_embed — remove a local embed and restore the registry-hosted version.

  • publish — publish an embedded or local package to a configured UPM registry.

  • create_package — scaffold a new local UPM package with optional Git initialization.
