# Nushell

> Use this tool when you need to leverage a modern shell with structured data capabilities for efficient coding and data processing. It solves problems such as running shell commands, managing processes, and querying web content, providing inputs like commands and queries, and outputs like processed data and command results. Ideal for use cases requiring direct access to a powerful shell, robust data processing, and seamless integration with AI coding agents.

## Description

A lightweight MCP server that provides AI coding agents with direct access to Nushell, a modern shell with structured data capabilities. Built in Rust, it offers six core tools: nu.exec for running Nushell commands (blocking or background), nu.output for reading background process output, nu.kill for terminating processes, nu.apply for fast code edits via local LLM endpoints, nu.search for web and package queries via SearXNG, and nu.fetch for downloading web content with HTML-to-Markdown conversion. The implementation emphasizes Nushell's native data processing pipelines, includes robust timeout handling and output buffering for long-running processes, and supports stateful working directory tracking across command executions.
