WHAT IT DOES

What sip018_hash does on Aibtc

AI agents call sip018_hash to retrieve information from Aibtc without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why sip018_hash is rated Low

This tool only computes a hash value locally without any side effects, signing, network calls, or data modification. It is a pure computation/read operation.

RECOMMENDED RULE

The rule that runs sip018_hash safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Aibtc, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sip018_hash, this is the rule to start with:

sip018_hash Allowed

sip018_hash is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sip018_hash": {}
  }

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

The button opens the PolicyLayer dashboard: create your workspace, connect Aibtc, apply this rule, and every sip018_hash call is checked against it from then on.
