THE RISK

Low Risk

Why list_crypto_currencies needs a policy

This tool retrieves and queries data about supported cryptocurrencies, network details, and restrictions. It has no side effects, does not create, modify, delete, or move funds. The 'Public endpoint' designation confirms it is informational only. Despite the financial domain context (crypto assets, payment protocol), the tool itself performs only data retrieval with no financial transactions or obligations incurred.

From the tool's definition Tool name is 'list_crypto_currencies' and description states it 'List all crypto assets' and is a 'Public endpoint' with no write, deletion, or financial operation capabilities.

POLICY

How to control list_crypto_currencies

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for list_crypto_currencies:

policy.json

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

list_crypto_currencies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
