swisscovery_search
AI agents call swisscovery_search to retrieve information from Pypi:swiss Academic Libraries without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches bibliographic records in the swisscovery academic library system. Search operations are inherently read-only with no side effects—they query and return data without modifying, deleting, or executing external actions. The blast radius of misuse is minimal: an agent could retrieve unwanted library records or waste resources, but cannot modify data, execute code, or cause financial harm.
From the tool's definition Tool name 'swisscovery_search' indicates a search operation. The server description emphasizes 'search and retrieve bibliographic and digitized records' as core functionality.
