List the top open-source AI agents in the Beacon registry, ranked by reputation
AI agents call top_agents to retrieve information from X402 Agents without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple read-only query of the Beacon registry to retrieve and display a ranked list of agents. It has no capability to modify, delete, or execute operations. The blast radius of misuse is minimal—an agent could only retrieve public information about open-source projects. No authentication, financial, or destructive operations are possible.
From the tool's definition Tool description states 'List the top open-source AI agents' which is a retrieval operation that queries the Beacon registry and returns ranked results without modification or side effects.
Attacks that exploit this kind of access
List the top open-source AI agents in the Beacon registry, ranked by reputation. It is categorised as a Read tool in the X402 Agents MCP Server, which means it retrieves data without modifying state.
Register the X402 Agents MCP server in PolicyLayer and add a rule for top_agents: 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 X402 Agents. Nothing to install.
top_agents 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 top_agents 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 top_agents. 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.
top_agents is provided by the X402 Agents MCP server (enrichgateagent-png/x402-agents). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
top_agents is one line of X402 Agents's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
