WHAT IT DOES

What memory_list_regions does on Jshookmcp

AI agents call memory_list_regions to retrieve information from Jshookmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why memory_list_regions is rated Low

Queries process memory layout without modifying or executing code, but exposes sensitive memory architecture information.

RECOMMENDED RULE

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

memory_list_regions Allowed

memory_list_regions is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "memory_list_regions": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about memory_list_regions

What does the memory_list_regions tool do? +

List all memory regions in a process with protection flags. If pid is omitted, the active browser renderer PID is auto-discovered from the current browser session. It is categorised as a Read tool in the Jshookmcp MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on memory_list_regions? +

Register the Jshook MCP server in PolicyLayer and add a rule for memory_list_regions: 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.

What risk level is memory_list_regions? +

memory_list_regions is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit memory_list_regions? +

Yes. Add a rate_limit block to the memory_list_regions 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.

How do I block memory_list_regions completely? +

Set action: deny in the PolicyLayer policy for memory_list_regions. 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.

What MCP server provides memory_list_regions? +

memory_list_regions 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.
