Bundlebox MCP Server

The zero-token software factory for AI coding agents. Scan, pack, route and run work across Claude Code, Codex, Gemini CLI, Cursor, Copilot, OpenCode, Aider and any custom agent, and measure every token a session used and was spared. It runs locally over stdio via the published package.

People who work with codex, context engineering and developer tools and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
