## 🎯 Why?

MCP is becoming the default way for agents to call tools, but most useful internal tools are still plain CLIs. Building a full MCP server for each command requires SDK boilerplate, packaging, and maintenance. cli2mcp fills this gap with a zero-dependency adapter that turns a command template into a callable MCP tool instantly.

**Target audience:** Agent developers, platform engineers, and AI tinkerers who want to expose CLI utilities, scripts, and internal tools to Claude, Cursor, or custom MCP clients without writing server code.

## ✨ Features

- ✨ **Wrap any command with {placeholders} as an MCP tool**
- ✨ **Auto-generate JSON Schema from placeholders**
- ✨ **Works over stdio with initialize, tools/list, and tools/call**
- ✨ **Timeouts, stderr capture, and non-zero exit reporting**
