List ALL threat actors the workspace is currently tracking in OPTIX.
AI agents call actor.list to retrieve information from OPTIX: Operational Platform for Threat Intelligence Exploration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves a list of threat actors from the OPTIX platform. It performs no creation, modification, deletion, code execution, or financial operations. The 'list' operation is a standard read-only query that returns existing data. While the data returned may be sensitive (threat actor information), the tool itself is non-destructive and has no side effects beyond information disclosure.
From the tool's definition Tool name 'actor.list' and description 'List ALL threat actors the workspace is currently tracking in OPTIX' indicate a retrieval operation with no modifications or side effects.

List ALL threat actors the workspace is currently tracking in OPTIX. It is categorised as a Read tool in the OPTIX: Operational Platform for Threat Intelligence Exploration MCP Server, which means it retrieves data without modifying state.
Register the OPTIX: Operational Platform for Threat Intelligence Exploration MCP server in PolicyLayer and add a rule for actor.list: 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 OPTIX: Operational Platform for Threat Intelligence Exploration. Nothing to install.
actor.list 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.list 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.list. 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.list is provided by the OPTIX: Operational Platform for Threat Intelligence Exploration MCP server (AdamWaldie/OPTIX-MCP). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
