extract_archive · Tafa MCP Server MCP: Risk & Policy

WHAT IT DOES

What extract_archive does on Tafa MCP Server

AI agents invoke extract_archive to trigger actions in Tafa MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why extract_archive needs a policy

Extracting an archive writes files to the filesystem (potentially overwriting existing files), which could be destructive if files are overwritten without warning. However, without a description, the exact behavior is unknown. Based on the name alone, it primarily executes an extraction operation that creates/writes files.

From the tool's definition Tool name 'extract_archive' with empty description; sibling tools include 'compress_files', 'delete_file', 'delete_directory' suggesting file system manipulation capabilities
