vapi_create_squad · Mcp Vapi MCP: Risk & Policy

WHAT IT DOES

What vapi_create_squad does on Mcp Vapi

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

WHY IT NEEDS A POLICY

Why vapi_create_squad needs a policy

This tool creates a new squad resource (a collection of voice assistants configured for handoff workflows), which is a Write operation that adds data to the system reversibly. While squad creation could enable complex call flows, the tool itself only creates/configures the squad structure; it does not execute calls, delete data, or move money.

From the tool's definition Tool description states 'Create a squad of assistants' — explicitly a creation operation that modifies data by adding a new squad resource to the Vapi.ai system.
