• Write any text file: Overwrite or create new text files with UTF-8 encoding.
• Edit text in-place: Perform search-and-replace operations on any readable file.
• Simple API: Exposes tools via MCP for easy automation and integration.
• FastMCP-based: Built on top of the FastMCP server for high performance.
