create_erc20_token

THE RISK

High Risk

Deploying a new ERC20 token involves executing a smart contract deployment transaction on-chain. While not destructive, it is an Execute-category action with high severity because it triggers an external blockchain operation that creates a permanent on-chain artifact, consumes gas, and could be misused to deploy malicious or fraudulent tokens at scale.

From the tool's definition Create a new ERC20 token — deploys a new smart contract on the BNB Chain blockchain, which is an irreversible on-chain execution action

HOW TO CONTROL CREATE_ERC20_TOKEN

PolicyLayer is an MCP gateway — it sits between your AI agents and BNB Chain MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_erc20_token:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_erc20_token": {
      "limits": [
        {
          "counter": "create_erc20_token_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

create_erc20_token stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

What does the create_erc20_token tool do? +

Create a new ERC20 token. It is categorised as a Execute tool in the BNB Chain MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_erc20_token? +

Register the BNB Chain MCP server in PolicyLayer and add a rule for create_erc20_token: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches BNB Chain MCP. Nothing to install.

What risk level is create_erc20_token? +

create_erc20_token is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit create_erc20_token? +

Yes. Add a rate_limit block to the create_erc20_token rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_erc20_token completely? +

Set action: deny in the PolicyLayer policy for create_erc20_token. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_erc20_token? +

create_erc20_token is provided by the BNB Chain MCP server (nirholas/bnbchain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
