WHAT IT DOES

What proto_auto_detect does on Jshookmcp

AI agents call proto_auto_detect to retrieve information from Jshookmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why proto_auto_detect is rated Low

Analyzes hex data to identify protocols; no data modification, execution, or side effects.

From the tool's definition Auto-detect protocol pattern from hex payload samples.

RECOMMENDED RULE

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

proto_auto_detect Allowed

proto_auto_detect is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "proto_auto_detect": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about proto_auto_detect

What does the proto_auto_detect tool do? +

Auto-detect a protocol pattern from one or more hex payload samples. It is categorised as a Read tool in the Jshookmcp MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on proto_auto_detect? +

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

proto_auto_detect is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit proto_auto_detect? +

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

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

proto_auto_detect 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.
