AI agents call get_report_by_id to retrieve information from OpenCTI 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 threat intelligence report data by ID, which is a read-only query operation with no side effects. It fits the 'Read' category (retrieves data; no side effects). Severity is low because unauthorized access to threat intelligence reports, while sensitive, does not enable direct harm compared to write, execute, or destructive operations.
From the tool's definition Tool name 'get_report_by_id' and description indicating retrieval ('獲取' means 'get/retrieve') of OpenCTI reports by identifier. No modification, deletion, or execution capability indicated.
Documented attack patterns abuse exactly the kind of access get_report_by_id gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenCTI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_report_by_id:
{
"version": "1",
"default": "deny",
"tools": {
"get_report_by_id": {}
}
}get_report_by_id is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

根據ID獲取OpenCTI報告. It is categorised as a Read tool in the OpenCTI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenCTI MCP Server MCP server in PolicyLayer and add a rule for get_report_by_id: 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 OpenCTI MCP Server. Nothing to install.
get_report_by_id 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_report_by_id 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_report_by_id. 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_report_by_id is provided by the OpenCTI MCP Server MCP server (zxzinn/opencti-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
