WHAT IT DOES

What top_coins does on Cryptosense

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

RISK

Why top_coins is rated Low

This tool retrieves cryptocurrency market data (top coins by market capitalization) without modifying state or executing code. It is a standard read operation returning market intelligence. The empty description reduces confidence slightly, but server context and tool naming strongly indicate a simple query/lookup function. Severity is low because misuse would only return incorrect market data without side effects.

From the tool's definition Tool name 'top_coins' indicates a data retrieval operation. Server description explicitly mentions 'Get prices, trending coins, market overview, top coins by market cap' as core functionality.

RECOMMENDED RULE

The rule that runs top_coins safely

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

top_coins Allowed

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

policy.json

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

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

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