get_literature_service_metadata
AI agents call get_literature_service_metadata to retrieve information from Literature MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries metadata about the literature service itself, a read-only operation. It has no side effects, does not execute code, modify data, delete anything, or commit financial obligations. Metadata retrieval is a basic informational lookup typical of service introspection APIs, carrying minimal risk.
