AI agents call mirror_get_contract_state 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 tool retrieves contract storage information from the Hedera blockchain without creating, modifying, or deleting data. It is a pure read operation that queries existing state. The blast radius is minimal—an AI agent querying contract storage cannot cause financial loss, execute code, or modify blockchain state. The risk is informational only.
From the tool's definition Tool name 'mirror_get_contract_state' and description 'Get contract storage state' indicate a query/retrieval operation. The verb 'Get' and phrase 'Query specific storage slots' confirm read-only access to blockchain state data without modification.
Attacks that exploit this kind of access
Get contract storage state (key-value pairs). Query specific storage slots or get all state. 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_get_contract_state: 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_get_contract_state 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_get_contract_state 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_get_contract_state. 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_get_contract_state 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.
