What memory_find_accesses does on Jshookmcp
AI agents invoke memory_find_accesses 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_find_accesses is rated High
Attaches hardware breakpoints to memory addresses, executing intrusive debugging operations on live processes.
From the tool's definition Sets a hardware breakpoint, auto-rearms after each hit, captures faulting instruction

The rule that runs memory_find_accesses 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_find_accesses, this is the rule to start with:
memory_find_accesses 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_find_accesses call is checked against it from then on.
Questions about memory_find_accesses
Find what writes to or accesses a memory address (Cheat Engine MWT workflow). Sets a hardware breakpoint on the target address, auto-rearms after each hit, captures the faulting instruction address + context + timestamp, and optionally disassembles the instruction. Returns aggregated hits with per-hit instruction details. 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_find_accesses: 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_find_accesses 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_find_accesses 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_find_accesses. 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_find_accesses 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.
