Performs third-party enrichment lookup for the provided URL.
AI agents call lookup-url to retrieve information from Enrichment MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves threat intelligence data about a URL from external services. It has no side effects—it only reads and returns information. The operation is non-destructive, non-financial, and does not execute code or commands. Even if an AI agent misuses it by looking up arbitrary URLs, the blast radius is limited to information disclosure about those URLs, with no capability to modify systems or data.
From the tool's definition Tool description states it 'Performs third-party enrichment lookup' which is a query/retrieval operation against threat intelligence services (VirusTotal, Shodan, AbuseIPDB). No modification, execution, deletion, or financial operations occur.
Attacks that exploit this kind of access
Performs third-party enrichment lookup for the provided URL. It is categorised as a Read tool in the Enrichment MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enrichment MCP Server MCP server in PolicyLayer and add a rule for lookup-url: 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 Enrichment MCP Server. Nothing to install.
lookup-url 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 lookup-url 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 lookup-url. 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.
lookup-url is provided by the Enrichment MCP Server MCP server (synackpwn/enrichment-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
