WHAT IT DOES

What register_my_agent does on Thenvoi MCP Server

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

WHY IT NEEDS A POLICY

Why register_my_agent needs a policy

The tool creates a new agent identity by registering it in the system. This is a Write operation (create) that modifies platform state by adding a new agent. Severity is high because an agent registration could establish a new identity that subsequent tool calls (like creating chat rooms, sending messages, posting events) would operate under.

From the tool's definition Tool name is 'register_my_agent' and description states 'Register a new remote agent.' This creates a new agent identity/entity in the Thenvoi platform.
