Stability AI MCP Server is an MCP (Model Context Protocol) server that integrates MCP clients like Claude Desktop with Stability AI's Stable Diffusion image manipulation APIs. It allows users to generate, edit, upscale, and manipulate images using tools powered by Stability AI's hosted REST API. Users need a Stability AI API key (free tier available) to get started.
How to use Stability AI MCP Server?
Install the server via npm or configure it in your MCP client (e.g., Claude Desktop) by setting the STABILITY_AI_API_KEY environment variable and optionally IMAGE_STORAGE_DIRECTORY.

All generated images are saved automatically to the configured local directory.
