Imagen MCP Server

# Imagen MCP Server (VS Code Extension) Manage and configure the Imagen MCP server from VS Code: - Securely store your Google AI API key (Secret Storage) - Pick the image model (default `gemini-3-pro-image-preview`) - Auto-generate `.vscode/mcp.json` so MCP works out of the box - Use MCP image tools including generation, editing, and generation with up to 3 reference images (references can be used as actual visual inputs per prompt) - **Standalone installation** — no additional files required in your workspace ## Requirements - **Python 3** must be installed on your system - The extension automatically creates a virtual environment and installs dependencies ## Commands (Command Palette) - **Imagen MCP: Set API Key** — stores key in Secret Storage - **Imagen MCP: Select Model** — sets `imagenMcp.modelId` - **Imagen MCP: Generate MCP Config** — writes `.vscode/mcp.json` with command/args/env - **Imagen MCP: Reinstall Python Environment** — recreates the virtual environment (useful for troubleshooting) ## Settings - `imagenMcp.apiKey` (string) — optionally set your Google AI key in settings; it syncs to secret storage and `.vscode/mcp.json`. Stored in settings as plain text. You'll get a warning toast with a shortcut to set it when missing. - `imagenMcp.modelId` (default `gemini-3-pro-image-preview`) ## Installation - Marketplace: search **Imagen MCP Server** (auto-updates) - VSIX: run `npm run package` then "Install from VSIX…" ## Behavior - On activation, the extension automatically: 1. Sets up a Python virtual environment (stored in VS Code's global storage) 2. Installs required dependencies (fastmcp, Pillow, pillow-heif) 3. Creates `.vscode/mcp.json` using the bundled server and your stored API key The virtual environment is shared across all workspaces, so setup only happens once. ## License MIT
