ttya_reject · Networkselfmd MCP: Risk & Policy

WHAT IT DOES

What ttya_reject does on Networkselfmd

AI agents use ttya_reject 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_reject needs a policy

The tool rejects (declines) a pending visitor connection, which is a reversible modification to network state—the visitor could re-request access. This is a Write operation rather than Destructive since rejection is not permanent data deletion and can be undone by accepting a new request.

From the tool's definition Tool name 'ttya_reject' and description 'Reject a pending visitor (not yet implemented)' indicate a state-change operation that modifies visitor/connection status in the P2P network.

Verdict

ttya_reject Rate-limited

ttya_reject stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
