Why fetch_deposit_address needs a policy

This tool retrieves cryptocurrency deposit address information from an exchange, which is a read-only query operation. It does not create, modify, delete, execute code, or initiate financial transactions. The worst-case misuse scenario would be exposing a user's deposit address to unauthorized parties, but the address itself is typically non-sensitive and intended for receiving deposits.

From the tool's definition Tool name contains 'fetch' and description states it 'Fetches the deposit address' — a pure retrieval operation with no side effects or modifications.

POLICY

How to control fetch_deposit_address

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

policy.json

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

fetch_deposit_address 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 CCXT MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
