AI agents call get_stix_type 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 a knowledge base without modifying, deleting, or executing any operations. It is a simple lookup function that returns object type information based on a STIX identifier. There are no side effects, no code execution, no destructive operations, and no financial implications.
From the tool's definition Tool name 'get_stix_type' and description 'Get object type by stix ID' indicate a retrieval operation that queries the MITRE ATT&CK knowledge base to retrieve metadata about a STIX object.
Documented attack patterns abuse exactly the kind of access get_stix_type 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_stix_type:
{
"version": "1",
"default": "deny",
"tools": {
"get_stix_type": {}
}
}get_stix_type is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get object type by stix ID. 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_stix_type: 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_stix_type 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_stix_type 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_stix_type. 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_stix_type 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.
