AuraImage MCP Server
Enables AI agents to audit images for LCP savings, migrate assets to AuraImage CDN, generate alt text, create responsive tags, and preview smart crops directly from the editor.
README
@auraimage/mcp-server
Model Context Protocol server that gives any MCP-compatible AI agent (Claude Code, Cursor, Cline, Continue, etc.) direct access to the AuraImage toolkit — auditing, migrating, and generating responsive image markup without leaving the editor.
Tools exposed
| Tool | Description |
|---|---|
audit_lcp |
Scans a project directory for unoptimized images and estimates LCP savings. |
migrate_assets |
Uploads local images to AuraImage and returns the new CDN URLs. Supports dryRun: true. |
generate_alt |
Generates accessible alt text for an image URL using vision AI. |
generate_responsive_tag |
Returns a <picture> element with AVIF + WebP srcsets for the given image. |
smart_crop_preview |
Returns crop variant URLs for an image at the requested width/height. |
Configuration
Add the server to your project's .mcp.json:
{
"mcpServers": {
"auraimage": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@auraimage/mcp-server@latest"],
"env": {
"AURA_SECRET_KEY": "${AURA_SECRET_KEY}"
}
}
}
}
Environment variables
| Variable | Needed by | Notes |
|---|---|---|
AURA_SECRET_KEY |
migrate_assets |
Your project's Secret Key — signs upload tokens. Keep it server-side. |
audit_lcp, generate_alt, generate_responsive_tag, and smart_crop_preview need no credentials. generate_alt is generated server-side by the AuraImage API (GPT-5.6 Luna) for images already on the AuraImage CDN, rate-limited per IP. The server always starts without any environment variables; a tool that is missing its key returns a clear error when called.
Run standalone
npx @auraimage/mcp-server@latest
The server speaks stdio and is compatible with every MCP-aware client.
