Why burn_erc20_tokens needs a policy

Burning tokens is irreversible — tokens sent to the zero address or destroyed via a burn function cannot be recovered. This permanently removes assets from circulation, qualifying as Destructive. The blast radius is critical because an AI agent misusing this tool could permanently destroy a user's crypto holdings with no possibility of recovery.

From the tool's definition Burn ERC20 tokens (send to zero address or call burn function if available)

POLICY

How to control burn_erc20_tokens

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for burn_erc20_tokens:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "burn_erc20_tokens"
  ]
}

burn_erc20_tokens disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
