Get metadata information of a local ZIP file
AI agents call getZipInfo to retrieve information from ZIP MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries metadata about ZIP archives (such as file listings, compression info, sizes) without creating, modifying, or deleting any data. It has no side effects and poses minimal security risk if misused by an AI agent, as it only exposes information that already exists in the archive.
From the tool's definition Tool name 'getZipInfo' combined with description 'Get metadata information of a local ZIP file' indicates retrieval of information without modification. The verb 'get' and context of 'metadata information' confirm read-only semantics.
