artscii

LLMs can't draw. This MCP can.

ASCII art, kaomoji, animations, diagrams, charts, image conversion & procedural characters — 11 focused tools for AI agents.

81 curated arts × 12 motions = 972 terminal animations. 153,600 unique procedural characters from a single seed. Plus 100 kaomoji, 11 diagram types, FIGlet banners, and image-to-ASCII with braille mode.

MCP Tools

Box Frames

Draw borders around any text with 5 styles:

┌───────┐   ╔═══════╗   ╭───────╮   ┏━━━━━━━┓   +-------+
│ hello │   ║ hello ║   │ hello │   ┃ hello ┃   | hello |
└───────┘   ╚═══════╝   ╰───────╯   ┗━━━━━━━┛   +-------+
 single      double      rounded       bold        ascii

Options: padding, align (left/center/right), title in top border.

Charts

Unified chart tool with 3 types: progress, sparkline, heatmap.

Progress:   ███████████████░░░░░ 75%
Sparkline:  ▁▂▃▄▅▆▇█▇▅▃▁
Heatmap:     A B C
           X ░▒█
           Y ▓░▒

Animations

Compose any art (noun) with a motion (verb) to create terminal animations. 81 arts × 12 motions = 972 combinations. Custom text works too.

animate("apple", "bounce")     → bouncing apple
animate("trophy", "progress")  → trophy rides a progress bar 0→100%
animate("lock", "reveal")      → line-by-line reveal
animate("GAME OVER", "blink")  → blinking custom text

Motions: bounce, shake, blink, slide, reveal, fade, pulse, rain, progress, wave, jump, talk

Output: script (bash for terminal playback) or frames (raw data)

Character

Procedural ASCII character generator. One seed → one unique character. 153,600 standard combinations (16 species × 10 eyes × 8 mouths × 10 hats × 12 accessories).

character("alice")                   character("bob", mood: "happy")

   ____                                  /\_/\
  ]==== )                                ( ^ ^ )
  _____                                  ( u )
 / * * \                                  \_^_/
|   u   |
 \_____/
  |||||
   ~~o=o~~

Species: blob, cat, bear, robot, bird, bunny, ghost, alien, fox, frog, penguin, octopus, dragon, mushroom, cactus, skull

Mood presets: happy, sad, angry, surprised, sleepy, cool, love, silly — sets eyes+mouth in one param. Explicit eyes/mouth still override.

Mini mode: 2-line inline characters for chat and status lines.

mini blob: (^ ^)    mini cat: /^ ^\    mini robot: [^ ^]
            (u)                >u<                  [u]

Same seed always produces the same character. Output works directly with the animate tool — try wave, jump, or talk motions.

Compose

Combine multiple text blocks horizontally (side-by-side) or vertically (stacked):

┌───┐ ┌───┐         ┌───┐
│ A │ │ B │         │ A │
└───┘ └───┘         └───┘
 horizontal          ---
                    ┌───┐
                    │ B │
                    └───┘
                    vertical

Options: gap, align (top/middle/bottom), separator (vertical mode).

Image Conversion

Convert images (URL or base64) to ASCII art. Two render modes:

• ascii — character ramp (.:-=+*#%@), classic look
• braille — Unicode braille dots (⠿), 8x resolution per character

Options: size (16/32/64), invert, contrast, gamma, threshold (braille).

Diagrams

11 diagram types with unicode, rounded, and ascii border styles.
