Frugal

Overview

Frugal is an open routing layer for AI tools that intelligently directs tool calls based on policies and evaluates every result. As a Model Context Protocol server, it lets AI assistants like Claude and Cursor use Frugal's routing capabilities as callable tools, eliminating manual copying between applications.

Frugal runs locally on your machine through the npm package frugal-mcp, which communicates over stdio. No authentication is required—it works immediately after installation. The latest release is v0.1.1, with full source code available at brainsparker/frugal on GitHub.

Frugal appears in the AI & Agents category on mcp.site and works with any MCP client, including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you're the maintainer, you're invited to claim this listing to verify ownership and keep information up to date.
