Create a new Aptos account with a random private key. This generates a new account that can be used for transactions on the Aptos blockchain. Returns the account address, private key, and public key.
Part of the Aptos Blockchain Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use create_account 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_account repeatedly, creating or modifying resources faster than any human could review. Intercept'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.

Create a new Aptos account with a random private key. This generates a new account that can be used for transactions on the Aptos blockchain. Returns the account address, private key, and public key.. 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.
Add a rule in your Intercept YAML policy under the tools section for create_account. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Aptos Blockchain Server MCP server.
create_account 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_account rule in your Intercept 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 Intercept policy for create_account. 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_account is provided by the Aptos Blockchain Server MCP server (cuongpo/aptos-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
