WHAT IT DOES

What memory_first_scan does on Jshookmcp

AI agents invoke memory_first_scan 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.

RISK

Why memory_first_scan is rated High

Initiates a memory scan process, triggering external operation with system-level access.

RECOMMENDED RULE

The rule that runs memory_first_scan 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_first_scan, this is the rule to start with:

memory_first_scan Rate-limited

memory_first_scan 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_first_scan call is checked against it from then on.

FAQ

Questions about memory_first_scan

What does the memory_first_scan tool do? +

How do I enforce a policy on memory_first_scan? +

Register the Jshook MCP server in PolicyLayer and add a rule for memory_first_scan: 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_first_scan? +

memory_first_scan is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit memory_first_scan? +

Yes. Add a rate_limit block to the memory_first_scan 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_first_scan completely? +

Set action: deny in the PolicyLayer policy for memory_first_scan. 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_first_scan? +

memory_first_scan 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.
