Query comprehensive account data from Hedera Mirror Node REST API. RETURNS: Balance, EVM address, creation time, keys, memo, transactions (optional) FREE: No transaction fees (REST API query) USE FOR: Account inspection, transaction history, state verification.
AI agents call mirror_query_account to retrieve information from HashPilot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval operation against a blockchain Mirror Node REST API. It queries and inspects account information without creating, modifying, deleting, or executing any state-changing operations. Even though it accesses sensitive data (keys, transaction history), the tool itself performs no destructive, financial, or write operations.
From the tool's definition Tool description states 'Query comprehensive account data' and 'Account inspection, transaction history, state verification' — all read-only operations.

It is categorised as a Read tool in the HashPilot MCP Server, which means it retrieves data without modifying state.
Register the HashPilot MCP server in PolicyLayer and add a rule for mirror_query_account: 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 HashPilot. Nothing to install.
mirror_query_account 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 mirror_query_account 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 mirror_query_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.
mirror_query_account is provided by the HashPilot MCP server (justmert/hashpilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
