THE RISK

Why delete_blacklist needs a policy

The name strongly suggests deletion of blacklist entries in a cryptocurrency trading bot context. Removing items from a trading blacklist could allow the bot to trade previously banned assets, potentially leading to significant financial or operational harm. Deletion operations are typically irreversible, placing this in the Destructive category. Confidence is reduced due to the empty description.

From the tool's definition Tool name 'delete_blacklist' implies irreversible removal of entries from the trading blacklist; description is empty and uninformative.

POLICY

How to control delete_blacklist

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_blacklist"
  ]
}

delete_blacklist disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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