Get all assets in the MITRE ATT&CK framework (ICS domain only)
AI agents call get_all_assets 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 and queries data from the MITRE ATT&CK knowledge base without modifying, executing operations on, or deleting any data. The 'get_all_' prefix pattern across sibling tools confirms this is a read-only operation. The blast radius of misuse is minimal—an agent would only obtain publicly available threat intelligence information about Industrial Control System (ICS) assets documented in the framework.
From the tool's definition Tool name 'get_all_assets' and description 'Get all assets in the MITRE ATT&CK framework (ICS domain only)' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_all_assets 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_assets:
{
"version": "1",
"default": "deny",
"tools": {
"get_all_assets": {}
}
}get_all_assets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all assets in the MITRE ATT&CK framework (ICS domain only). 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_assets: 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_assets 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_assets 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_assets. 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_assets 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.
