FAQ from Game dev. Spritesheet Forge

What input formats and file sizes are supported?

PNG, GIF, and WebP are accepted. The maximum file size is 20 MB per file.

How can I handle files larger than about 185 KB?

For files ≥ ~185 KB, use the upload endpoint (POST to https://mcp.clawstudiouo.com/upload) and pass the returned URL to the tool. Base64 encoding large files creates JSON‑RPC payloads that most MCP clients reject.

How does authentication work?

Spritesheet Forge uses GitHub OAuth 2.1 with PKCE. No API keys needed—MCP clients like Claude Desktop and Claude Code run the OAuth flow automatically. Session tokens are valid for 30 days.

Is there a free tier? What are the limits?

Yes, the free tier allows 100 operations per GitHub account per month. Output files expire 1 hour after creation, so do not reuse output URLs across sessions.

Can I run my own instance?

The README includes a self-hosting section (not fully shown), so self-hosting is possible. For the hosted version, the server endpoint is https://mcp.clawstudiouo.com/mcp.
