pensketch

Overview

pensketch is an MCP server that lets you check, render and rasterise hand-sketched diagrams. Any MCP-compatible AI assistant can call pensketch's tools directly, deciding when to use them as part of a conversation or agent workflow.

It runs locally on your machine via the npm package @pensketch/mcp, speaking MCP over stdio. No authentication or credentials are needed — install with npx -y @pensketch/mcp and it works immediately. The latest release is v0.13.0.

pensketch is a Design tool on mcp.site and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and others across the ecosystem. If you maintain pensketch, claim this listing to verify ownership and keep information up to date.
