AI agents call agent_details 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 queries and returns information about a single agent record. It retrieves data without creating, modifying, deleting, executing code, or triggering external actions. The operation is non-destructive and read-only, making it a low-severity information retrieval function typical of API lookups in registries or databases.

Get full details for one agent in the Beacon registry by its agent_id (e.g. 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 agent_details: 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.
agent_details 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 agent_details 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 agent_details. 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.
agent_details 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.
agent_details 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.
