AI agents call get_campaigns_by_alias to retrieve information from MITRE ATT&CK 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 campaign information from the MITRE ATT&CK knowledge base using an alias parameter. It performs a read-only lookup operation with no side effects—it does not create, modify, delete, execute code, or affect external systems. The action is purely informational retrieval, consistent with other Read category tools like 'get_all_campaigns' on the same server.
From the tool's definition Tool name 'get_campaigns_by_alias' and description 'Get campaigns by their alias' indicate a query/retrieval operation with no modification capability.

{
"version": "1",
"default": "deny",
"tools": {
"get_campaigns_by_alias": {}
