AI agents call mirror_list_contracts 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 and displays publicly available blockchain data about deployed contracts. It performs a read-only query operation with no side effects, no code execution, and no data modification. The returned information (contract IDs, bytecode, creation metadata) is already public on the blockchain. Confidence is high because the verb 'list' and description clearly indicate a query operation.
From the tool's definition Tool name 'mirror_list_contracts' contains 'list' which queries data. Description states 'List all smart contracts deployed on Hedera.
Attacks that exploit this kind of access
List all smart contracts deployed on Hedera. Returns contract IDs, bytecode, and creation info. 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_list_contracts: 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_list_contracts 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_list_contracts 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_list_contracts. 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_list_contracts 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.
