THE RISK

Why create-token needs a policy

Creating a token on Pump.fun is a financial operation: it deploys a new tradeable asset on the Solana blockchain, typically requiring SOL payment for fees and liquidity. This commits real financial resources and creates a live financial instrument that can be traded.

From the tool's definition "Create a new Pump.fun token" on a platform for creating, buying, and selling tokens on Solana — token creation involves deploying a smart contract and committing SOL/financial resources on-chain.

Documented attack patterns abuse exactly the kind of access create-token gives an agent:

POLICY

How to control create-token

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create-token": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to create-token is blocked until a human approves it. The rest of the server keeps working.
