Figma vs Kernelcad
A side-by-side look at the Figma and Kernelcad MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Figma for architecture & design work as a local process; choose Kernelcad for architecture & design as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Figma when
- You need dedicated capabilities in the Architecture & Design domain.
- You prefer a local stdio subprocess transport.
- You want tools like
list_file_variables, get_published_variables, modify_variables.
Choose Kernelcad when

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Figma has no declared pricing — check the project's own site. Kernelcad has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add figma-2 and kernelcad as separate keys in the same mcpServers object, and your assistant will call tools from either one.
