Get total subscriber count for a publication
AI agents call get-subscriber-count to retrieve information from Paragraph MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The operation is non-destructive and poses minimal security risk even if misused by an AI agent, as it only exposes an existing metric. Classification as Read is appropriate.
