Why remove_fee_liquidity needs a policy

Burning LP tokens permanently removes liquidity and destroys the tokens themselves—this is an irreversible operation that cannot be undone. While it could be classified as Financial (it affects monetary assets), the destructive nature of token burning (permanent destruction rather than transfer) makes Destructive the more precise category.

From the tool's definition Tool description explicitly states 'Remove liquidity from a Fee AMM pool by burning LP tokens.' The action of burning LP tokens is irreversible and destroys financial assets.

POLICY

How to control remove_fee_liquidity

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

policy.json

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

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