nemu_vm_state_load
Load VM state into guest memory. Takes ctx values and table values as hex strings and writes them at the specified base addresses. Use to bridge Python LiteVM state into native VM: run Python vm.run(), dump ctx/table as hex, then load into nemu guest memory before calling bb2i34u32clsb.

What nemu_vm_state_load does on Jshookmcp
AI agents invoke nemu_vm_state_load 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 nemu_vm_state_load is rated High
Writes execution state into VM guest memory, enabling arbitrary native code execution.
From the tool's definition Load VM state into guest memory, writes at specified base addresses
Attacks that exploit this kind of access
The rule that runs nemu_vm_state_load 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 nemu_vm_state_load, this is the rule to start with:
nemu_vm_state_load 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 nemu_vm_state_load call is checked against it from then on.
Questions about nemu_vm_state_load
Load VM state into guest memory. Takes ctx values and table values as hex strings and writes them at the specified base addresses. Use to bridge Python LiteVM state into native VM: run Python vm.run(), dump ctx/table as hex, then load into nemu guest memory before calling bb2i34u32clsb. 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 nemu_vm_state_load: 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.
nemu_vm_state_load 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 nemu_vm_state_load 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 nemu_vm_state_load. 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.
nemu_vm_state_load 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.
