WHAT IT DOES

What deployToken does on Token Minter

AI agents use deployToken to commit financial operations through Token Minter — usually the final step of a payment, billing, or trading workflow. A call moves real money.

THE RISK

Critical Risk

Why deployToken needs a policy

Deploying an ERC-20 token is a financial operation that commits on-chain resources (gas fees), creates a new financial instrument with an initial supply, and has irreversible blockchain consequences. Misuse by an AI agent could result in unauthorized token creation, financial losses from gas expenditure, and the introduction of fraudulent or unintended financial instruments across multiple blockchains.

POLICY

How to control deployToken

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

policy.json

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

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

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

What risk level is deployToken? +

deployToken is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit deployToken? +

Yes. Add a rate_limit block to the deployToken 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 deployToken completely? +

Set action: deny in the PolicyLayer policy for deployToken. 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 deployToken? +

deployToken is provided by the Token Minter MCP server (kukapay/token-minter-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
