Install GenMedia MCP Servers (Pre-compiled Binaries)

This skill provides direct, clone-free instructions to download, install, and register the Google GenMedia Model Context Protocol (MCP) servers using official release binaries.

When to Invoke this Skill

• Required media synthesis tools (lyria_generate_music, nanobanana_image_generation, or ffmpeg_*) are not present in your active tool list.
• You want a fast, pre-compiled setup without installing the Go runtime or cloning the source repository.

Installation Procedure

1. Run the Online Installer

This command fetches the official install script, which automatically detects your OS and architecture, downloads the latest pre-compiled binaries from the GitHub Releases page, and extracts them into your ~/.local/bin/ folder.

curl -sL https://raw.githubusercontent.com/GoogleCloudPlatform/genmedia-creative-studio/main/experiments/mcp-genmedia/mcp-genmedia-go/install-online.sh | bash

Note: Ensure that ~/.local/bin is in your system's executable search PATH.

Configuration & Registration

1. Update your MCP Configuration

Add the installed binaries to your platform's global MCP configuration file (typically ~/.gemini/antigravity-cli/mcp_config.json or your IDE's settings).

Configure the environment to include your Google Cloud Project ID and Region:

{
  "mcpServers": {
    "lyria": {
      "command": "/Users/YOUR_USER/.local/bin/mcp-lyria-go",
      "env": {
        "PROJECT_ID": "YOUR_GCP_PROJECT",
        "LOCATION": "us-central1"
      }
    },
    "nanobanana": {
      "command": "/Users/YOUR_USER/.local/bin/mcp-nanobanana-go",
      "env": {
        "PROJECT_ID": "YOUR_GCP_PROJECT",
        "LOCATION": "us-central1"
      }
    },
    "avtool": {
      "command": "/Users/YOUR_USER/.local/bin/mcp-avtool-go"
    }
  }
}

2. Antigravity CLI (agy) Plugin Sync

If you are running the Antigravity CLI (agy) client and want to sync all the expert skills (such as genmedia-producer, genmedia-audio-engineer, etc.) and their integrated MCP servers that are configured under your main Gemini config, you must import the plugins into Antigravity:

antigravity plugin import gemini

This will automatically scan, register, and stage all your active Gemini plugins and MCP servers under your Antigravity configuration folder (~/.gemini/config/).

3. Reload and Verify the Session

To register and activate the new tool definitions in your active agent's context, you must reload your active session:

• In Gemini CLI, run: /skills reload
• In Antigravity (agy), exit your current chat session and restart the client (e.g., using antigravity --continue or starting a new turn) so the tool schemas are re-negotiated and locked.
