Search OPTIX for a specific indicator of compromise (IOC) by its raw value.
AI agents call search.indicator 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 performs a read-only search operation against threat intelligence data. It retrieves or queries indicators of compromise without creating, modifying, deleting, or executing any operations. The search capability is a fundamental read operation with minimal blast radius if misused by an AI agent—it simply returns threat intelligence information the agent is already authorized to access.
From the tool's definition Tool name 'search.indicator' and description 'Search OPTIX for a specific indicator of compromise (IOC) by its raw value' clearly indicates a query/search operation with no modification of data.

Register the OPTIX: Operational Platform for Threat Intelligence Exploration MCP server in PolicyLayer and add a rule for search.indicator: 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.
search.indicator 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 search.indicator 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 search.indicator. 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.
