## Quality 85/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 4 of 6 tools declare all four hints; missing: get_sprite (destructiveHint, idempotentHint); load_art (destructiveHint, idempotentHint)
- pass `tools.token_cost`: about 2,373 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 1 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 2,373 tokens to load them all

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-29 `open_tileset_editor` changed (description, inputSchema)
  - before: 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.
  - after: 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; sets SpriteForge derives add 4 variants of tile 15 as tiles 16-19, mixed into painted floors) 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 20 grids for Wang, 49 for platformer, in mask order), palette + base (a seamless square texture; the 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 or 20x1 image is a strip, a 4x5 one a sheet, 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.

## Tools (6)

- `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.
- `load_art`: Loads an edit session's sprite into the SpriteForge editor card. Only the card calls it.
- `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; sets SpriteForge derives add 4 variants of tile 15 as tiles 16-19, mixed into painted floors) 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.

The result says which view it opened and how it read the PNG. The user's edits save to the edit session.
- `save_art`: Saves the user's edits from the SpriteForge editor card to its edit session. Only the card calls it.
