Get all names and synonyms for a compound
AI agents call get_compound_synonyms 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.

It performs a straightforward read operation with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—an agent could retrieve synonym data for any compound, but this poses no security, safety, or operational risk.
From the tool's definition Tool name 'get_compound_synonyms' and description 'Get all names and synonyms for a compound' indicate data retrieval with no modification or execution.
