WHAT IT DOES

What generate_hooks does on Jshookmcp

AI agents invoke generate_hooks 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 generate_hooks is rated High

Frida interceptor scripts execute dynamic instrumentation code, hooking into running processes.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

generate_hooks Rate-limited

generate_hooks 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.

          "max": 10,

        }
      ]
    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every generate_hooks call is checked against it from then on.

FAQ

Questions about generate_hooks

What does the generate_hooks tool do? +

How do I enforce a policy on generate_hooks? +

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

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

Can I rate-limit generate_hooks? +

Yes. Add a rate_limit block to the generate_hooks 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 generate_hooks completely? +

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

generate_hooks 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.
