actor_lookup
AI agents call actor_lookup to retrieve information from Oracle-42 DarkIntel MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve threat actor information from a threat intelligence database without modifying, deleting, or executing external operations. The 'lookup' pattern typically indicates a read operation. Lower confidence due to empty description; if 'actor' refers to executable actions rather than threat actors, category could shift to Execute.
From the tool's definition Tool name 'actor_lookup' and server context (threat intelligence) suggest querying or retrieving data about threat actors from a darknet intelligence database. No description provided to confirm side effects.
Attacks that exploit this kind of access
actor_lookup. It is categorised as a Read tool in the Oracle-42 DarkIntel MCP MCP Server, which means it retrieves data without modifying state.
Register the Oracle-42 DarkIntel MCP server in PolicyLayer and add a rule for actor_lookup: 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 Oracle-42 DarkIntel MCP. Nothing to install.
actor_lookup 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 actor_lookup 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 actor_lookup. 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.
actor_lookup is provided by the Oracle-42 DarkIntel MCP server (mintmas/oracle42-darkintel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
