Get all threat actor groups in the MITRE ATT&CK framework
AI agents call get_all_groups 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 is a straightforward query/retrieval operation that accesses publicly available threat intelligence documentation. There are no destructive, financial, or code-execution implications. Even if misused by an AI agent, the worst outcome is information gathering about known threat actors, which is already public knowledge and causes no harm to systems or data.
From the tool's definition Tool name and description indicate it 'Get all threat actor groups' from a knowledge base with 'no side effects' — purely retrieves data from the MITRE ATT&CK framework without creating, modifying, deleting, executing, or moving resources.
Documented attack patterns abuse exactly the kind of access get_all_groups gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MITRE ATT&CK MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_all_groups:
{
"version": "1",
"default": "deny",
"tools": {
"get_all_groups": {}
}
}get_all_groups is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all threat actor groups in the MITRE ATT&CK framework. It is categorised as a Read tool in the MITRE ATT&CK MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MITRE ATT&CK MCP Server MCP server in PolicyLayer and add a rule for get_all_groups: 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 MITRE ATT&CK MCP Server. Nothing to install.
get_all_groups 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 get_all_groups 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 get_all_groups. 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.
get_all_groups is provided by the MITRE ATT&CK MCP Server MCP server (stoyky/mitre-attack-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
