Before you install Aseprite AI Artist
AgenticMart scanned Aseprite AI Artist on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.
What it can access
- An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.
Before you install
- Pin the version you reviewed instead of always installing the latest release.
- Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
- Maintained by with-pebbly on GitHub, 538 stars and 31 forks. Popularity is not proof of safety.
- Last code change: Oct 22, 2026.
- Open-source license: MIT.
Tools Aseprite AI Artist exposes (18)
Listed by the server itself during our scan of commit a32a2a5.
preflightCheck that Aseprite is connected and report what this session can do. Call this FIRST in any pixel-art task and stop if `ready` is false — every editing tool writes into the user's open Aseprite window ('live') or into a batch Aseprite this server owns ('headless'), and there is no useful fallback w
sprite_infoFull structured state of a sprite: dimensions, colour mode, palette, every layer (with opacity, blend mode, visibility, group nesting), every frame with its duration, animation tags, slices and the current selection. Read this before editing — guessing at layer names or frame counts is the most comm
sprite_manageOpen, create, focus, resize, save and close sprites in the running Aseprite session. Ops: 'list' (open documents), 'new', 'open', 'activate', 'save', 'save_as', 'close', 'resize_canvas', 'set_properties', 'slice_create', 'slice_update', 'slice_delete'. Canvas resize keeps existing pixels — pass an a
lookSee what is actually on the canvas. Ops: • 'preview' — a nearest-neighbour upscaled PNG of the active frame (~1024px long edge). Use for overall read: silhouette, colour, whether it looks like the thing. • 'ascii' — an exact text grid, one glyph per pixel with a colour legend and coordinate rulers.
read_pixelsRead a rectangular region as structured data: a list of distinct colours plus a row-major index grid. Use this when you need to compute over pixels (sample a palette from art, find a silhouette edge, copy a region) rather than just look at them. For eyeballing, 'look' is cheaper.
drawApply a batch of drawing operations to one cel, as a single undoable action. Ops: pixels, line, polyline, rect, ellipse, fill, replace, dither, gradient, clear, blit, text, grid. Batch aggressively — a whole sprite in one call is normal and correct, and it means the user can undo your work with one
selectRead or change the active selection. Ops: 'get', 'none', 'all', 'rect', 'ellipse', 'color' (select every pixel matching a colour), 'invert', 'grow', 'shrink'. A selection scopes draw, transform and recolor, which is usually cheaper and safer than masking by hand.
transformMove, flip, rotate or scale pixels on ONE cel — the target layer's image on the target frame. Ops: 'translate', 'flip', 'rotate', 'scale', 'outline', 'crop_to_content'. To transform part of a cel, crop the region out with `draw` op 'blit' first; there is no selection-scoped transform. Rotation is on
layerManage layers. Ops: 'list', 'create', 'rename', 'delete', 'reorder', 'set' (visibility/opacity/blend/lock), 'group', 'ungroup', 'merge', 'duplicate', 'activate'. Pass `batch` to run several in one undoable action — building a rig in one call is the normal use. 'duplicate' takes an optional `toSprite
frameManage animation frames. Ops: 'list', 'add', 'duplicate', 'delete', 'set_duration', 'activate', 'reorder'. Durations are milliseconds per frame and carry most of the life in a cycle — hold a contact pose longer than a pass pose. Use `count` to add several at once and `durations` to set a whole cycle
tagManage animation tags — the named frame ranges a game engine imports as 'idle', 'walk', 'attack'. Ops: 'list', 'create', 'update', 'delete'. Tag every cycle before export; an untagged spritesheet is a pile of frames the engine cannot address.
celManage cels — one layer's image on one frame. Ops: 'list', 'create', 'clear', 'delete', 'move', 'copy', 'link', 'unlink', 'set' (position/opacity), 'tween', 'oscillate'. 'move' is how you shift a whole limb between frames without redrawing it; 'link' shares one image across frames so a static part o
paletteRead and shape the sprite's palette. Ops: • 'get' — current palette with per-colour usage counts. • 'set' — write specific indices, or replace the palette wholesale. • 'preset' — load a bundled palette by key: ~2000 of them, the classics (pico8, gameboy, cga, nes…) and the most-downloaded on Lospec
recolorChange colours in a region by intent, staying palette-legal. Ops: • 'shade' — darken or lighten with proper hue shifting (shadows cool, highlights warm). Use this instead of picking a darker hex by hand. • 'snap' — pull off-palette pixels onto the nearest palette colour by perceptual (CIELAB) distan
validateLint a sprite against pixel-art rules and report concrete, located problems. Checks: off-palette colours, orphan/stray pixels, broken or doubled outlines, banding, semi-transparent (soft or resized) pixels, empty layers, untagged frames and uniform frame timing; `expect` adds per-layer frame ranges
referenceBring an external image into the sprite as a reference layer, so you can trace proportions or sample colours from it. Ops: 'import' (place an image on a locked, semi-transparent layer above the art), 'sample_palette' (read its dominant colours without importing), 'list', 'remove'. A concept sheet or
exportWrite game-ready files. Ops: 'png' (single frame), 'gif' (animation), 'spritesheet' (packed sheet plus a JSON atlas with per-frame and per-tag data), 'frames' (numbered PNGs), 'aseprite' (save a copy of the source). Spritesheet is what an engine actually consumes: pass `sheetType` and `byTag` to con
tilesetWork with Aseprite tilemap layers. Ops: • 'list' — tilesets in the sprite. • 'create_layer' — a new empty tilemap layer on a given grid. • 'get' — tile count and, with a path, the tiles as one packed PNG. • 'stamp' — place tiles by grid coordinate. x/y are grid cells, not pixels. • 'pack' — turn a h
