bulk_create_contacts · SparrowDesk MCP: Risk & Policy

WHAT IT DOES

What bulk_create_contacts does on SparrowDesk

AI agents use bulk_create_contacts to create or update resources in SparrowDesk — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SparrowDesk environment.

WHY IT NEEDS A POLICY

Why bulk_create_contacts needs a policy

This tool creates new contacts (reversible data modification) in bulk. While the action is repeatable and can be undone (unlike destructive operations), creating many contacts simultaneously poses a moderate risk if an AI agent misuses it—potential for spam, duplicate contact generation, or resource exhaustion. The polling mechanism (get_bulk_job_status) is asynchronous but does not change the Write classification.

From the tool's definition Tool name 'bulk_create_contacts' and description 'Create multiple contacts in one request' explicitly indicates creation of multiple data records.

bulk_create_contacts Rate-limited
