The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

How do I install the Spritesheet Forge MCP server?
Spritesheet Forge is a hosted endpoint at https://mcp.clawstudiouo.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Spritesheet Forge MCP server?
Spritesheet Forge is an MCP server listed in the public MCP registry as io.github.LAXY9887/spritesheet-forge. Game-dev sprite tools: PNG/GIF to spritesheet, split, trim, animate. OAuth-authenticated MCP server. This page covers its hosted endpoint (https://mcp.clawstudiouo.com/mcp).
Is the Spritesheet Forge MCP server safe to use?
Spritesheet Forge scores 67 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Spritesheet Forge MCP server expose?
Spritesheet Forge exposes 8 tools: server_info, png_to_spritesheet, split_spritesheet, trim_png, gif_to_spritesheet, and 3 more. Their descriptions and schemas cost roughly 2,565 tokens of context every time the server is loaded.
Does the Spritesheet Forge MCP server require authentication?
Its publisher declares no required credentials for Spritesheet Forge. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the Spritesheet Forge MCP server still maintained?
Spritesheet Forge is still listed in the MCP registry, but we have not been able to reach this channel for several days and its score is decaying. We last reached this channel on 2 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
