How to generate spritesheets in Cursor
Connect AutoSprite to Cursor with a simple MCP setup. Add one configuration block and start creating game sprites directly from Cursor.
02
Add AutoSprite to Cursor
Paste the JSON below into .cursor/mcp.json for one project or ~/.cursor/mcp.json for all projects.
03
Check the connection
Reload Cursor, go to Settings → MCP, and confirm AutoSprite shows a green status.
.cursor/mcp.json (in your project) or ~/.cursor/mcp.json (global)
{
"mcpServers": {
"autosprite": {
"url": "https://www.autosprite.io/api/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_KEY"
}
}
}
}Replace YOUR_API_KEY with a key from the API Keys page. Keys start with vspk_.
New to MCP? It lets the Cursor Agent use AutoSprite directly. Once connected, the Cursor Agent automatically chooses from 30 tools to create and animate your game assets. Learn how AutoSprite MCP works.

Pro tip
Make it a Cursor rule
A rule file in .cursor/rules/ is loaded into every Agent session in the project. Add a short art-pipeline rule and the Agent reaches for AutoSprite instead of dropping in another placeholder.
- Ships with the repo, so every teammate's Agent behaves the same way.
- Keeps exports in a consistent folder with consistent frame sizes.
- Stops the Agent from generating coloured rectangles or inline SVGs.

When this game needs 2D character sprites or
animations, use the AutoSprite MCP tools
(create_character, generate_spritesheet) instead
of placeholder graphics. Save exports to
public/assets/ and read the JSON atlas before
writing any preload or animation code.FAQ
Cursor sprite generation questions
What is MCP, and what does AutoSprite add to Cursor?
MCP (Model Context Protocol) is an open standard that lets a coding agent call external tools. AutoSprite runs as a hosted MCP server over HTTP, so once it is connected the Cursor Agent can create a character, animate it, and export a transparent PNG spritesheet plus a JSON atlas — then write the code that loads them into Unity, Godot, Phaser, or another engine.
Why doesn't Cursor show the AutoSprite tools?
MCP tools only run in Agent mode — plain chat and inline Cmd-K edits will not call them. Also check Settings → MCP to confirm the server shows a green status; a red status usually means the Authorization header still says YOUR_API_KEY. Reload the window after editing mcp.json so Cursor re-reads it.
Should the config go in the project or in ~/.cursor?
Both work. Use .cursor/mcp.json inside the repo when the whole team should get the server with the project (put the key in an env reference, not in git). Use ~/.cursor/mcp.json when it is your personal setup across every project.
What data leaves my machine?
Only what the Agent puts in a tool call — your prompt, and any image you explicitly ask it to upload. AutoSprite is a hosted HTTP MCP server: it does not read, index, or receive your codebase, and it has no access to your filesystem. Cursor writes the returned files into your project itself.
