search_items
AI agents call search_items to retrieve information from Wayback Machine MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool searches archive.org items, which is a read-only operation that queries existing historical data without creating, modifying, deleting, or executing operations. The empty description and contextual sibling tools (get_archived_page, get_snapshots) support classification as a retrieval mechanism.
From the tool's definition Tool name 'search_items' on Wayback Machine MCP server alongside 'get_archived_page' and 'get_snapshots' indicates data retrieval.
