## Description

MCP Server Developer Tool provides a set of utilities for AI assistants to interact with the local file system and execute shell commands. Built by Daniel, it implements four core tools: executing shell commands with timeout control, displaying file contents with line range options, searching files using regular expressions, and writing content to files with append or overwrite modes. The server uses Go's reflection capabilities to dynamically handle tool execution and communicates via stdio transport, making it suitable for integration with any MCP-compatible client. This implementation is particularly valuable for development workflows requiring file manipulation, code inspection, and command execution without leaving the conversation interface.
