What is Grok2 Image MCP Server?

An MCP (Model Context Protocol) server for generating and editing images using the Grok image model from xAI. It serves developers integrating image capabilities into AI workflows via MCP-compatible clients.

How to use Grok2 Image MCP Server?

Install via npx in your MCP client configuration, setting the required environment variable XAIAPI_KEY. The server exposes two tools: generate_image and edit_image, invoked by the client with parameters such as prompt, image URLs, aspect ratio, resolution, and batch count.

Key features of Grok2 Image MCP Server

  • Image generation from text prompts with configurable aspect ratio and resolution
  • Image editing using natural language instructions with 1–3 source images
  • Local file path support for editing; server auto-reads and encodes them
  • Optional image proxy domain to replace imgen.x.ai in returned URLs
  • Optional HTTP/HTTPS network proxy for API requests

Use cases of Grok2 Image MCP Server

  • Generate images from descriptive prompts with custom dimensions and batch count
  • Edit existing images by providing URLs, base64 data, or local file paths
  • Overcome network restrictions on imgen.x.ai using an image proxy domain
