Get all subtechniques in the MITRE ATT&CK framework
AI agents call get_all_subtechniques 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 information from the MITRE ATT&CK knowledge base without creating, modifying, or deleting any data. It simply queries and returns a list of subtechniques—a standard read operation with no side effects. The blast radius is minimal as it only exposes publicly available threat intelligence information.
From the tool's definition Tool name: 'get_all_subtechniques'. Description: 'Get all subtechniques in the MITRE ATT&CK framework'. The verb 'Get' and the read-only nature of retrieving framework data without modification.
Documented attack patterns abuse exactly the kind of access get_all_subtechniques 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_subtechniques:
{
"version": "1",
"default": "deny",
"tools": {
"get_all_subtechniques": {}
}
}get_all_subtechniques is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all subtechniques 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_subtechniques: 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_subtechniques 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_subtechniques 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_subtechniques. 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_subtechniques 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.
