Mark a conversation as read/seen.
AI agents use mark_conversation_as_seen to create or update resources in LinkedIn Intelligence MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LinkedIn Intelligence MCP Server environment.
This tool creates or modifies data reversibly—it changes the read/seen flag on a conversation, which is a non-destructive state change that can be undone (marked as unseen again). It does not retrieve data (Read), execute arbitrary code (Execute), permanently delete data (Destructive), or move money (Financial).
