AI agents call search_gallica to retrieve information from Gallica without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches a digital library (Gallica) and retrieves text or metadata. It queries and returns data without side effects, fitting the Read category. The lack of tool description is offset by strong contextual evidence from the server description and sibling tool names, all pointing to informational retrieval from a public archive.
From the tool's definition Tool name 'search_gallica' and sibling tools 'advanced_search_gallica', 'get_snippets', and 'download_text' all indicate retrieval operations.
