Get PubMed citations and scientific literature references
AI agents call get_literature_references to retrieve information from PubChem MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves publicly available scientific literature metadata from PubMed/PubChem. It has no side effects, does not execute code or commands, does not modify or delete data, and does not involve financial transactions. The blast radius of misuse is minimal—an agent could only retrieve citations that are already public. This is a straightforward Read operation.
From the tool's definition Tool name 'get_literature_references' and description 'Get PubMed citations and scientific literature references' indicate data retrieval only. No modification, deletion, execution, or financial operations are performed.
