Gemini AI (Optional)	Direct requests with .gemini or MCP-enhanced requests with .gemini-mcp

Usage

Connecting MCP Servers

Via GUI:

1. Open Meteor GUI (Right Shift) and navigate to the MCP tab

3. Enter server name and command (e.g., node /path/to/spotify-mcp-server/dist/index.js)

4. Enable "Auto Connect" (optional)

5. Save and Connect

Example Server: Spotify MCP

For a practical example, see Spotify MCP Server (requires local setup).

Server	Command	Use Case

StarScript Examples

After connecting servers, tools become available in any StarScript context:

{spotify.spotify_get_track_name()}

{spotify.spotify_get_track_progress_formatted()}

Use these expressions in:

- HUD text elements

- Chat macros

- Anywhere Starscript placeholders are used

Chat Command Examples

# Control playback

.spotify:spotify_next

.spotify:spotify_set_volume volume_percent=50

Gemini AI Integration (Optional)

Setup

1. Navigate to MCP tab and click "Configure Gemini API"

2. Enter API key from ai.google.dev

3. Select model (Gemini 2.5 Pro, Flash, or Flash Lite)

4. Test connection and save

Usage

Simple prompts:

.gemini "Explain what StarScript is"

{gemini("What is the current Minecraft version?")}

MCP-enhanced prompts:

.gemini-mcp "Play some jazz music"

{gemini_mcp("What song is currently playing?")}

The .gemini-mcp command allows Gemini to automatically discover and call any connected MCP tool. Tool usage is reported in the response.
