WHAT IT DOES

What network_export_har does on Jshookmcp

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

RISK

Why network_export_har is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs network_export_har safely

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

network_export_har Rate-limited

network_export_har 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.
