Rftools

Overview

Rftools is a Model Context Protocol server that brings 241 RF and electronics calculators plus 13 simulation tools to AI agents. It exposes these capabilities as tools that Claude, Cursor, VS Code, and other AI assistants can invoke directly during conversations, making complex RF and electronics calculations accessible to your workflow.

The server runs locally on your machine via the npm package rftools-mcp, which communicates over stdio with no authentication required. Installation is simple: npx -y rftools-mcp. The current release is v1.7.3, published under the MIT license with full source code available at antonpogrebenko-public/rftools-mcp on GitHub.

Rftools is listed in the AI & Agents category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this project, claim your listing to verify ownership and keep the information up to date.
