Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "spronta": {
      "command": "npx",
      "args": [
        "-y",
        "@spronta/mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add spronta -- npx -y @spronta/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "spronta": {
      "command": "npx",
      "args": [
        "-y",
        "@spronta/mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "spronta": {

Common questions

Is Spronta MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@spronta/mcp

MCP server for uploading, transforming, and serving images on a global CDN — directly from AI assistants.

Connect Claude, GPT, Cursor, Windsurf, or any MCP-compatible client to the Spronta Image CDN. Upload images from URLs or base64, apply real-time transforms (resize, crop, format conversion, smart crop, blurhash), create reusable presets, generate signed URLs, and monitor usage — all through natural language.

Why use this?

Upload images from AI — give your LLM an image URL and it uploads, optimizes, and returns a CDN link
Real-time transforms — resize, crop, convert to WebP/AVIF/JXL, smart crop with face detection
Global CDN delivery — images served from edge locations worldwide
Blurhash generation — automatic blur placeholders computed on upload
Signed URLs — HMAC-SHA256 signed URLs with expiration for private images
Named presets — create reusable transform configurations (e.g. thumbnail, hero, og-image)
No vendor lock-in — MIT licensed, open source

Quick start

Install

npm install -g @spronta/mcp

or use directly

npx @spronta/mcp

Claude Code

claude mcp add spronta \

-e SPRONTA_API_KEY=spronta_img_... \ -e SPRONTA_PROJECT_ID=your-project-id \ -- npx @spronta/mcp

How upload works

The upload_image tool handles the full upload pipeline in a single call:

You provide an image URL (or base64 data) and a filename
The server fetches the image
Requests a presigned upload URL from Spronta
Uploads the file directly to storage
Confirms the upload — Spronta computes the blurhash and detects dimensions
Returns the confirmed image with CDN URL, blurhash, and metadata
