api record

SpriteForge Editor opens pixel art in a free, no-account browser pixel editor. Use open_editor when the user wants to edit or touch up a sprite by hand, or open_full_editor straight away (same sources) when they want the full editor - layers, selection, shapes, frames with onion skin. Where the app shows interactive cards, the editor appears inline under the call and its Done button sends you a message with the session_id; otherwise give the user the edit link it returns. After they're done, call get_sprite to see the result and get the PNG (in a shell, download png_url with curl). Edit links…

_ is it live, free and safe measured by this hub
Is spriteforge-editor live?
Yes — it answered the hub's last check (checked 43m ago). It answered 100% of checks over the last 30 days.
Is spriteforge-editor free to use?
Not measured yet.
What tools does spriteforge-editor have?
6 tools: load_art, open_editor, get_sprite, open_full_editor, open_tileset_editor, save_art.
Is spriteforge-editor safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • load_art unknown never probed

    Loads an edit session's sprite into the SpriteForge editor card. Only the card calls it.

  • open_editor unknown never probed

    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.

    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 unknown never probed

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id ec5cd59694580d83.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/ec5cd59694580d83/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
