Mint new tokens of a previously deployed custom coin using the token factory. Only the coin deployer can mint new tokens. This increases the total supply of the coin and sends the minted tokens to a specified recipient.

AI agents call mint_coin to retrieve information from Aptos Blockchain Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though mint_coin only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access mint_coin gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Mint new tokens of a previously deployed custom coin using the token factory. Only the coin deployer can mint new tokens. This increases the total supply of the coin and sends the minted tokens to a specified recipient.. It is categorised as a Read tool in the Aptos Blockchain Server MCP Server, which means it retrieves data without modifying state.
Register the Aptos Blockchain Server MCP server in PolicyLayer and add a rule for mint_coin: 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 Aptos Blockchain Server. Nothing to install.
mint_coin is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mint_coin 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.
Set action: deny in the PolicyLayer policy for mint_coin. 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.
mint_coin is provided by the Aptos Blockchain Server MCP server (cuongpo/aptos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
