WHAT IT DOES

What list-networks does on Hats Protocol MCP Server

AI agents call list-networks to retrieve information from Hats Protocol MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list-networks is rated Low

This tool retrieves and displays supported blockchain networks and their configurations. It has no side effects, does not execute code or transactions, and does not modify any data. It is purely informational, making it a Read category tool with low severity since the blast radius of misuse is minimal—an AI agent cannot cause harm by listing network information.

From the tool's definition Tool name 'list-networks' and description 'List all supported blockchain networks with their configurations' indicate a read-only retrieval operation that queries configuration data without modifying state or executing transactions.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list-networks safely

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

list-networks Allowed

list-networks 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": {
    "list-networks": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Hats Protocol MCP Server, apply this rule, and every list-networks call is checked against it from then on.
