mcp-filesystem-server

The server implements robust path validation including absolute path resolution, explicit allowed directories, and comprehensive symlink resolution with security checks to prevent directory traversal attacks. All file operations leverage this validation. The 'modify_file' tool uses regex, which could theoretically be vulnerable to ReDoS if patterns are untrusted, but this is mitigated by the overall path restrictions. No hardcoded secrets or arbitrary code execution mechanisms ('eval') were found. The server operates with the privileges of its running user, which is standard for local tools.
