memory_process_control
Suspend or resume a target process for consistent memory snapshots. Suspend freezes all threads (NtSuspendProcess on Win32, SIGSTOP on Linux, task_suspend on macOS) so memory reads/scans see a consistent state. Resume thaws all threads. Useful before memory_dump or memory_first_scan for processes...

What memory_process_control does on Jshookmcp
AI agents invoke memory_process_control 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.
Why memory_process_control is rated High
Suspending or resuming a process affects its execution state with broad system impact.
From the tool's definition Suspend freezes all threads... Resume thaws all threads
Attacks that exploit this kind of access
The rule that runs memory_process_control 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 memory_process_control, this is the rule to start with:
memory_process_control 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 memory_process_control call is checked against it from then on.
Questions about memory_process_control
Suspend or resume a target process for consistent memory snapshots. Suspend freezes all threads (NtSuspendProcess on Win32, SIGSTOP on Linux, task_suspend on macOS) so memory reads/scans see a consistent state. Resume thaws all threads. Useful before memory_dump or memory_first_scan for processes with actively-changing memory. Cross-platform. It is categorised as a Execute tool in the Jshookmcp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Jshook MCP server in PolicyLayer and add a rule for memory_process_control: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Jshookmcp. Nothing to install.
memory_process_control is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the memory_process_control rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for memory_process_control. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
memory_process_control is provided by the Jshook MCP server (@jshookmcp/jshook). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
