session_warmup · Linkedin Company Admin MCP: Risk & Policy

WHAT IT DOES

What session_warmup does on Linkedin Company Admin

AI agents invoke session_warmup to trigger actions in Linkedin Company Admin. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

It triggers external operations with side effects beyond simple data retrieval, fitting the Execute category. Misuse could expose session state or authentication tokens, warranting medium severity.
