Описание
MCP server for generating and editing images using xAI's Grok image model, supporting text prompts, batch generation, local files, and optional proxy configurations.
README
An MCP (Model Context Protocol) server for image generation and editing using the Grok image model from xAI.
Note: This package was previously published as grok2-image-mcp-server. That package is now deprecated — please use
grok-image-mcpinstead.
Features
- Image Generation — Generate images from text prompts with configurable aspect ratio, resolution, and batch count
- Image Editing — Edit existing images with natural language instructions, supporting 1–3 source images
- Local File Support — Provide local image paths for editing; the server reads and encodes them automatically
- Image Proxy — Optional proxy domain for
imgen.x.aito handle network restrictions - HTTP Proxy — Optional network proxy for API requests
Installation
Using npx (recommended)
{
"mcpServers": {
"grok_image": {
"command": "npx",
"args": ["grok-image-mcp"],
"env": {
"XAIAPI_KEY": "your-xai-api-key"
}
}
}
}

| Parameter | Type | Required | Description |
|---|---|---|---|
prompt |
string | ✅ | Text description of the image to generate |
n |
number | Number of images (1–10, default 1) | |
aspect_ratio |
string | Aspect ratio (1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 2:1, 1:2, auto, etc.) |
|
resolution |
string | Resolution (1k or 2k, default 1k) |
edit_image
Edit existing images using a text prompt.
| Parameter | Type | Required | Description |
|---|---|---|---|
prompt |
string | ✅ | Text description of the desired edits |
image_urls |
string[] | ✅ | 1–3 source images: URLs, base64 data URIs, or local file paths |
n |
number | Number of output images (1–10, default 1) | |
aspect_ratio |
string | Override output aspect ratio (default: follows first input image) | |
resolution |
string | Resolution (1k or 2k, default 1k) |
Environment Variables
| Variable | Required | Description |
|---|---|---|
XAIAPI_KEY |
✅ | xAI API key |
XAIAPI_BASE_URL |
API base URL (default: https://api.x.ai/v1). Use a proxy if the API is inaccessible |
|
IMAGE_PROXY_DOMAIN |
Proxy domain to replace imgen.x.ai in returned image URLs |
|
HTTP_PROXY |
HTTP/HTTPS proxy for API requests (e.g. http://127.0.0.1:7890) |
Proxy Examples
API proxy:
XAIAPI_BASE_URL=https://api-proxy.me/xai/v1
Image proxy:
IMAGE_PROXY_DOMAIN=https://image.proxy.workers.dev
Network proxy:
HTTP_PROXY=http://127.0.0.1:7890
Using Cloudflare Workers to Proxy Image URLs
If image URLs from imgen.x.ai are inaccessible, deploy a Cloudflare Worker as a reverse proxy and set IMAGE_PROXY_DOMAIN to your custom domain:
addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request))
})
const TARGET_DOMAIN = 'imgen.x.ai'
async function handleRequest(request) {
const url = new URL(request.url)
const targetUrl = `https://${TARGET_DOMAIN}${url.pathname}${url.search}`
const init = {
method: request.method,
headers: request.headers,
body: request.method === 'GET' || request.method === 'HEAD' ? undefined : request.body,
redirect: 'follow'
}
const response = await fetch(targetUrl, init)
const newHeaders = new Headers(response.headers)
newHeaders.set('Access-Control-Allow-Origin', '*')
return new Response(response.body, {
status: response.status,
statusText: response.statusText,
headers: newHeaders
})
}

addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request))
})
const TARGET_DOMAIN = 'imgen.x.ai'
async function handleRequest(request) {
const url = new URL(request.url)
const targetUrl = `https://${TARGET_DOMAIN}${url.pathname}${url.search}`
const init = {
method: request.method,
headers: request.headers,
body: request.method === 'GET' || request.method === 'HEAD' ? undefined : request.body,
redirect: 'follow'
}
const response = await fetch(targetUrl, init)
const newHeaders = new Headers(response.headers)
newHeaders.set('Access-Control-Allow-Origin', '*')
return new Response(response.body, {
status: response.status,
statusText: response.statusText,
headers: newHeaders
