MCP Server
Generate Figviz diagrams from Claude Desktop, Cursor, and other AI assistants via the Model Context Protocol
The Figviz MCP server lets any Model Context Protocol
client — Claude Desktop, Cursor, Cline, Windsurf, and more — generate labeled science
and math diagrams through the Figviz API. Published on npm as
@figviz/figviz-mcp.
What it exposes
A single tool, generate_diagram: describe a diagram in plain text and get back
a hosted image URL. Options are quality (1k / 2k / 4k) and aspectRatio
(e.g. 16:9, 1:1).
Example prompts to try from your assistant:
- "labeled plant cell cross-section for 8th grade"
- "convex lens ray diagram, object between F and 2F"
- "acid–base titration setup for high school chemistry"
- "KWL chart graphic organizer, blank"
