Search MISP events by tag, type, value, category, or date range.
AI agents call misp_search_events to retrieve information from UltraProbe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from a MISP (Malware Information Sharing Platform) instance without modifying, deleting, or executing any operations. It performs read-only searches across events using filters, consistent with the Read category for search and query operations.
From the tool's definition Tool name 'misp_search_events' and description 'Search MISP events by tag, type, value, category, or date range' indicate a query/search operation with no side effects.

Register the UltraProbe MCP server in PolicyLayer and add a rule for misp_search_events: 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 UltraProbe. Nothing to install.
misp_search_events 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 misp_search_events 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 misp_search_events. 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.
misp_search_events is provided by the UltraProbe MCP server (ppcvote/misp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
