What memory_freeze_export does on Jshookmcp
AI agents use memory_freeze_export to create or update resources in Jshookmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Jshookmcp environment.
Why memory_freeze_export is rated Medium
An AI agent can call memory_freeze_export faster than any human can review: one bad instruction and it creates or modifies resources in Jshookmcp by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs memory_freeze_export 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_freeze_export, this is the rule to start with:
memory_freeze_export stays usable, but capped: an agent stuck in a loop can't make hundreds of changes 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_freeze_export call is checked against it from then on.
Questions about memory_freeze_export
Export all active freeze entries as structured JSON. Returns an array of freeze entries with freezeId, pid, address, value, valueType, intervalMs, and active flag. Optional pid filter to scope the export to a single process. Pure data export — no workflow, no replay. It is categorised as a Write tool in the Jshookmcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Jshook MCP server in PolicyLayer and add a rule for memory_freeze_export: 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_freeze_export is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the memory_freeze_export 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_freeze_export. 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_freeze_export 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.
