WHAT IT DOES

What close_tab does on Iconnect

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

RISK

Why close_tab is rated Medium

An AI agent can call close_tab faster than any human can review: one bad instruction and it creates or modifies resources in Iconnect by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs close_tab safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Iconnect, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For close_tab, this is the rule to start with:

close_tab Rate-limited

close_tab 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.

What risk level is close_tab? +

How do I block close_tab completely? +
