ttya_approve · Networkselfmd MCP: Risk & Policy

WHAT IT DOES

What ttya_approve does on Networkselfmd

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

WHY IT NEEDS A POLICY

Why ttya_approve needs a policy

This tool creates or modifies data (visitor approval status) in a reversible manner, fitting the Write category. It affects peer trust and access control in a P2P network context. Severity is medium because misuse could grant inappropriate network access, but the impact is scoped to individual visitor approvals rather than system-wide destruction.

From the tool's definition Tool name 'ttya_approve' combined with description 'Approve a pending visitor' indicates a state-changing operation that modifies the status of a visitor entity from pending to approved.
