AI agents call get_objects_by_content 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 appears to retrieve/query objects from the MITRE ATT&CK database based on content matching, consistent with other 'get_*' tools on the server. No side effects, modifications, deletions, code execution, or financial impact indicated. The empty description reduces confidence slightly, but the naming pattern and server context strongly suggest this is a read-only query tool.
From the tool's definition Tool name 'get_objects_by_content' suggests content-based querying/retrieval. Server context provides 'comprehensive access to the MITRE ATT&CK knowledge base' with sibling tools like 'get_all_assets', 'get_all_campaigns', 'get_all_groups' which are all…
Documented attack patterns abuse exactly the kind of access get_objects_by_content 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_objects_by_content:
{
"version": "1",
"default": "deny",
"tools": {
"get_objects_by_content": {}
}
}get_objects_by_content is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_objects_by_content. 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_objects_by_content: 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_objects_by_content 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_objects_by_content 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_objects_by_content. 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_objects_by_content 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.
