DiceBear Avatars

Generate deterministic, unique avatars from any seed string. Same seed always produces the same avatar. Choose from 30+ art styles including pixel art, bottts (robots), initials, adventurer, and more. Returns SVG URLs you can embed directly.

Tools

• generate_avatar — Generate an avatar URL for a given style and seed. The seed can be a username, email, or any string.
• list_styles — Returns all available avatar styles with descriptions.

When to use

• Default profile pictures for new users (deterministic = no database storage needed)
• Generating unique icons for items, categories, or projects
• Placeholder images during design prototyping
• Chat applications that need distinct avatars per participant

Example

Generate a robot-style avatar for the seed "alice":

curl -s -X POST https://gateway.pipeworx.io/dicebear/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"generate_avatar","arguments":{"style":"bottts","seed":"alice"}}}'

{
  "url": "https://api.dicebear.com/7.x/bottts/svg?seed=alice",
  "style": "bottts",
  "seed": "alice"
}
