WHAT IT DOES

What http2_probe does on Jshookmcp

AI agents invoke http2_probe to trigger actions in Jshookmcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why http2_probe is rated High

Sends network requests to external endpoints, triggering external operations with potential side effects.

RECOMMENDED RULE

The rule that runs http2_probe 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 http2_probe, this is the rule to start with:

http2_probe Rate-limited

http2_probe stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every http2_probe call is checked against it from then on.
