openrouter-imgen-mcp

Give your AI assistant the ability to generate and edit images. One install, multiple models, no vendor lock-in.

| Before | After | |--------|-------| | | |

Works with Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, and any MCP client.

• One API key, every image model. Gemini, GPT-5, and more through OpenRouter. Switch models with a word, not a code change.
• Generate, edit, and batch. Text-to-image, image editing with references, and batch operations (up to 20 parallel tasks).
• Style presets. Say "in watercolor style" or "as pixel art" and get consistent results. 8 built-in styles.
• Variations. Generate up to 4 takes from one prompt. Pick the best one.
• Smart file output. Save to a path or a directory. Files get descriptive names automatically.
• Pay for what you use. OpenRouter's per-token and per-image pricing means no subscriptions.

Get an OpenRouter API key, then add the server to your client.
