SpriteForge Editor does not always answer
Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

open
open_editor
Opens pixel art in SpriteForge's compact pixel editor - pencil, eraser, fill, colour picker, palette, undo and animation frames - as an interactive card where the app shows them, and returns an edit link (the same editor in a browser) and a session_id. No account needed. One source at most: png_base64 (an existing PNG), art (palette + index grid), or neither for a blank width x height canvas. Max 128x128 pixels and 256 colours. The user's edits save to the edit session automatically.
open_full_editor
Opens a sprite in SpriteForge's full pixel editor - layers, selection and move, line/rectangle/ellipse, mirror painting, brush sizes, animation frames with onion skin and playback, palette tools - as an interactive card where the app shows them, and returns an edit link that opens the same editor in a browser. One source at most: session_id (an edit session that's already open, or an edit link), png_base64 (an existing PNG), art (palette + index grid), or none for a blank width x height canvas. Max 128x128 pixels and 256 colours. The user's edits save to the edit session.
open_tileset_editor
Opens a tileset in SpriteForge's tileset editor as an interactive card where the app shows them, and returns an edit link that opens the same editor in a browser. For a Wang autotile set (16 tiles; tile i is drawn where the map cells at its corners are painted, NW=1 NE=2 SW=4 SE=8, so tile 15 is the solid base) the user paints a small map to see the tiles chain, draws on the map or on single tiles, and edits the base texture, which re-derives the edge tiles (tiles drawn by hand stay); a platformer set (49 tiles) is edited tile by tile. With session_id it opens a tileset that's already in an edit session, and kind (wang = flat floor terrain, wall, iso) switches that Wang set's preview, keeping its tiles and the user's edits. Otherwise it makes a new set from kind (wang, wall, iso or platformer; default wang) plus palette + tiles (16 or 49 grids in mask order), palette + base (a seamless square texture; the 16 Wang tiles are derived from it as SpriteForge does), png_base64 (a tileset sheet or a texture), or size alone for a blank set. With png_base64 and no layout, a 16x1 image is a strip, and a square one is a 4x4 sheet when its tiles look like a Wang set in mask order (tile 0 empty, or nearly every tile's corners matching tile 15 where its mask has that corner and tile 0 where it doesn't), else a texture. The result says which view it opened and how it read the PNG. The user's edits save to the edit session.
load
load_art
Loads an edit session's sprite into the SpriteForge editor card. Only the card calls it.
save
save_art
Saves the user's edits from the SpriteForge editor card to its edit session. Only the card calls it.
sprite
get_sprite
Returns the current state of a SpriteForge edit session: a preview image, its size and palette, how many edits were saved, and a PNG URL with the exact pixels at 1x (add &frame=N for another frame). With include_pixels it also returns the palette-index grid. Read-only.

SpriteForge Editor — questions
Answers built from our own checks of this server.
What can SpriteForge Editor do?
It exposes 6 tools, read directly from the server on our last check. Among them: get_sprite, load_art, open_editor, open_full_editor, open_tileset_editor, save_art. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is SpriteForge Editor working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 53 ms. The bar chart above shows every period we have measured.
The registry lists SpriteForge Editor as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect SpriteForge Editor?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does SpriteForge Editor need an API key?
No. SpriteForge Editor completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
