Crucially, the actual C# source code for the MCP server was not provided, making a comprehensive security audit impossible. The analysis is based solely on the README's description of features. The server's extensive file system and data manipulation capabilities (e.g., creating, copying, deleting files, writing to arbitrary cells, reading any data) present significant security risks if not implemented with robust input validation, path sanitization, and access control. Without code, there is no way to verify protection against path traversal, arbitrary code execution, or ReDoS attacks with `SearchWithRegex`. Running this server grants an AI agent powerful capabilities over local files, which inherently requires high trust and careful implementation.
