Fetch top 100 token corridors by number of transactions from Wormholescan API.
AI agents call get_top100_corridors to retrieve information from Wormhole Metrics without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves blockchain analytics data (transaction counts across token corridors) from an external API. It performs no mutations, executions, destructive actions, or financial transactions. The blast radius of misuse is minimal—an attacker could request this data repeatedly but could not compromise systems, delete data, or cause financial harm. This is a straightforward Read operation.
From the tool's definition Tool name 'get_top100_corridors' and description 'Fetch top 100 token corridors by number of transactions' indicate a read-only query operation that retrieves and analyzes data from the Wormholescan API without modifying, executing code, deleting data, or…
Attacks that exploit this kind of access
Fetch top 100 token corridors by number of transactions from Wormholescan API. It is categorised as a Read tool in the Wormhole Metrics MCP Server, which means it retrieves data without modifying state.
Register the Wormhole Metrics MCP server in PolicyLayer and add a rule for get_top100_corridors: 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 Wormhole Metrics. Nothing to install.
get_top100_corridors 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 get_top100_corridors 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 get_top100_corridors. 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.
get_top100_corridors is provided by the Wormhole Metrics MCP server (kukapay/wormhole-metrics-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
