Get one publication by PubMed id.
AI agents call mgnify_get_publication to retrieve information from MGnify MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It performs no data modification, does not execute code or external operations, and has no destructive or financial implications. The operation is a simple, safe data retrieval with minimal blast radius if misused by an AI agent.
