Install via .mcpb (Claude Desktop), plugin zip (Claude Desktop or Claude Code), or manual configuration. Set at least one API key (OPENAI_API_KEY or GEMINI_API_KEY) as an environment variable. Invoke the generate_image tool with a prompt and optional parameters, or use check_image_job to poll an in-progress job.

Image Gen

Open-source Claude plugin + stdio MCP server for generating and editing images via OpenAI gpt-image-2 and Google Gemini (gemini-3.1-flash-image-preview / gemini-3-pro-image-preview, aka Nano Banana / Pro). Bring your own OpenAI and/or Gemini API key.

Tools

- generate_image — Generate or edit an image via OpenAI gpt-image-2 or Google Gemini. Accepts a prompt plus optional reference images, model selection, size, and quality settings. - check_image_job — Poll a previously-started image generation job. PNGs land in ~/Pictures/image-gen/; the tool returns an inline JPEG thumbnail so the client can render the result immediately.

Install

Three install surfaces, depending on the client: | Artifact | Surface | What it gives you | |---|---|---| | image-gen-<os>-<arch>.mcpb | Claude Desktop (Install Extension) | MCP tools (generate_image, check_image_job) | | image-gen-plugin.zip | Claude Desktop or Claude Code | image-gen skill + /image-gpt + /image-gemini slash commands | | mcp/dist/index.js | Manual claude mcp add / claude_desktop_config.json | Same MCP, full manual control | Published .mcpb builds: darwin-arm64, darwin-x64, win32-x64. Linux users build from source via the Claude Code install guide.
