What memory_structure_compare does on Jshookmcp
AI agents call memory_structure_compare 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.
Why memory_structure_compare is rated Low
Tool analyzes memory structures for differences without modifying or executing code, purely comparative analysis.
From the tool's definition compare struct instances, identify differing vs constant fields, returns confidence scores

The rule that runs memory_structure_compare 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_structure_compare, this is the rule to start with:
memory_structure_compare is read-only, so it stays allowed. 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_structure_compare call is checked against it from then on.
Questions about memory_structure_compare
Compare struct instances to identify differing vs constant fields. Two modes: (1) Pairwise—compare address1 vs address2. (2) Group comparison (CE dissect data parity)—pass arrays of addresses in group1Addresses and group2Addresses. Group mode computes per-offset statistics and classifies fields as: between_groups (differs across groups—likely gameplay state), within_group (varies within groups—dynamic), constant_all (same everywhere—likely vtable, type flags). Returns confidence scores. It is categorised as a Read tool in the Jshookmcp MCP Server, which means it retrieves data without modifying state.
Register the Jshook MCP server in PolicyLayer and add a rule for memory_structure_compare: 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_structure_compare is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the memory_structure_compare 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_structure_compare. 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_structure_compare 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.
