$_mcbox

What is mcbox?

mcbox is a pluggable MCP (Model Context Protocol) server written in Bash and jq, fully tested using Bats, shellcheck and shfmt.

It aims to be lightweight, portable, and just good enough for AI agents that use local tool execution through stdio transport.

The project has a few non-goals:

• No concurrency/parallel processing
• No support for high throughput
• No streaming responses
• No MCP transports other than stdio

Aside from that, it’s a great way to provide your own tools for local AI agents, and write those tools in any programming language you like.
