WHAT IT DOES

What hippo_run_task does on Verimem

AI agents invoke hippo_run_task to trigger actions in Verimem. 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 hippo_run_task is rated High

This tool triggers external agent operations whose effects depend on the task argument passed to it. It executes code/logic within an agent context, making side effects unpredictable and dependent on what task is submitted. While not destructive by default, the execution of arbitrary tasks through an agent loop poses significant risk if an AI agent misuses it to perform unintended operations.

From the tool's definition Tool name 'hippo_run_task' combined with description 'Run a task through the HippoAgent wake loop' indicates execution of arbitrary tasks via an agent loop.

RECOMMENDED RULE

The rule that runs hippo_run_task safely

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

hippo_run_task Rate-limited

hippo_run_task 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.
