Performs third-party enrichment lookup for the provided domain.
AI agents call lookup-domain 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 and queries threat intelligence data from third-party services (VirusTotal, Shodan, AbuseIPDB) for informational purposes. It has no side effects, does not modify data, execute code, delete anything, or move money. It is a classic Read operation: passive data retrieval with no blast radius beyond information disclosure, which is the intended use case.
From the tool's definition Tool 'lookup-domain' 'Performs third-party enrichment lookup for the provided domain' — a query-only operation that retrieves threat intelligence data from external services without modifying or executing anything.
Attacks that exploit this kind of access
Performs third-party enrichment lookup for the provided domain. 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-domain: 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-domain 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-domain 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-domain. 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-domain 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.
