AI agents use create_managed_coin to create or modify resources in Aptos Blockchain Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call create_managed_coin repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Aptos Blockchain Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access create_managed_coin gives an agent. Each links to the full case and the policy that stops it:

Initialize a managed coin using existing Aptos framework. This works with pre-deployed managed coin modules and doesn't require Move compilation. Suitable for testing and development.. It is categorised as a Write tool in the Aptos Blockchain Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Aptos Blockchain Server MCP server in PolicyLayer and add a rule for create_managed_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.
create_managed_coin is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_managed_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 create_managed_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.
create_managed_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.
