AI agents call get_x402_service to retrieve information from X402hub without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and returns information (details, price, network, description, and code) about a service. It does not execute the code, make payments, or modify any data — it only fetches and displays read-only metadata about an x402 service.
From the tool's definition Full details for one x402 service by its endpoint URL or name: price, network, description, and ready-to-run code to call and pay it.
Attacks that exploit this kind of access
Full details for one x402 service by its endpoint URL or name: price, network, description, and ready-to-run code to call and pay it. It is categorised as a Read tool in the X402hub MCP Server, which means it retrieves data without modifying state.
Register the X402hub MCP server in PolicyLayer and add a rule for get_x402_service: 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 X402hub. Nothing to install.
get_x402_service 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_x402_service 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_x402_service. 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_x402_service is provided by the X402hub MCP server (zacharytroberts03-ctrl/x402hub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
