GenMedia MCP Servers for Antigravity

This directory contains the configuration files and agent skills necessary to use the Google GenMedia MCP Servers directly within Antigravity.

1. Configure MCP Servers

Antigravity manages custom MCP servers via a raw mcp_config.json file.

1. Open Antigravity.
2. Open the MCP Store panel via the ”…” dropdown at the top of the editor’s side panel.
3. Click on Manage MCP Servers.
4. Click on View raw config.
5. Copy the contents of the mcp_config.json file in this directory and paste it into the editor.
6. Replace YOUR_GOOGLE_CLOUD_PROJECT_ID and YOUR_GOOGLE_CLOUD_STORAGE_BUCKET with your actual GCP Project ID and GenMedia GCS bucket URI (e.g., gs://my-cool-bucket).

2. Install expert Agent Skills

Antigravity features a powerful Agent Skills engine. We have uplifted our expert media workflows into a central skills/ directory at the project root.

To install these skills for your Antigravity workspace, copy the desired skills into your .agents/skills/ directory:

Workspace Installation

This makes the skills available only within the current project.

mkdir -p .agents/skills
cp -r ../../skills/* .agents/skills/

Global Installation

This makes the skills available across all your Antigravity workspaces.

mkdir -p ~/.gemini/antigravity/skills
cp -r ../../skills/* ~/.gemini/antigravity/skills/

Available Skills

Once installed, the Antigravity agent will automatically discover the skills based on your request:

• genmedia-producer: The orchestrator for complex multi-step media workflows. Use when you want to “create a podcast” or “generate a storyboard”.
• genmedia-video-editor: Expert in FFmpeg composition, overlays, and GIF generation.
• genmedia-audio-engineer: Specialist in TTS synthesis, music generation, and mixing.
• genmedia-image-artist: Expert in high-fidelity visual generation and prompt optimization.

The agent will seamlessly read the instructions and orchestrate the GenMedia tools like a pro!
