WHAT IT DOES

What renef_memory_patch does on Renef

AI agents invoke renef_memory_patch to trigger actions in Renef. 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 renef_memory_patch is rated High

Memory patching directly modifies live process memory at arbitrary addresses, bypassing normal write protections. This is an Execute/Write hybrid but the act of patching memory in a running process is an active execution-level operation with irreversible effects on the running process state.

RECOMMENDED RULE

The rule that runs renef_memory_patch safely

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

renef_memory_patch Rate-limited

renef_memory_patch 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.
