List supported Hyperlane chains and their canonical domain ids.
AI agents call hyperlane_list_chains to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries static or semi-static configuration data about supported blockchain chains in the Hyperlane interoperability protocol. It performs no writes, deletions, code execution, or financial operations. The blast radius of misuse is minimal—an AI could only gain information about available chains, which does not compromise security or cause harm.
From the tool's definition Tool name contains 'list' and description states it 'List[s] supported Hyperlane chains and their canonical domain ids' — a pure information retrieval operation with no side effects.
Attacks that exploit this kind of access
List supported Hyperlane chains and their canonical domain ids. It is categorised as a Read tool in the Tenzro Ledger MCP MCP Server, which means it retrieves data without modifying state.
Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for hyperlane_list_chains: 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 Tenzro Ledger MCP. Nothing to install.
hyperlane_list_chains 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 hyperlane_list_chains 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 hyperlane_list_chains. 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.
hyperlane_list_chains is provided by the Tenzro Ledger MCP server (https://canton-mcp.tenzro.network/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
