Why mint_test_erc20_tokens needs a policy

The tool name explicitly references minting ERC20 tokens, which is a financial operation involving token creation. While 'test' in the name suggests it may operate on a test network (lowering real-world financial risk), the server description mentions minting tokens as a core operation. The description is empty, reducing confidence.

From the tool's definition Tool name 'mint_test_erc20_tokens' combined with server context involving minting tokens, financial operations, and ERC20 tokens

POLICY

How to control mint_test_erc20_tokens

PolicyLayer is an MCP gateway — it sits between your AI agents and Story SDK MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for mint_test_erc20_tokens:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mint_test_erc20_tokens": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to mint_test_erc20_tokens is blocked until a human approves it. The rest of the server keeps working.
