Look up Windows API definition (signature, params, DLL, category)
AI agents call api_lookup to retrieve information from Windows Forensics MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward reference lookup tool that retrieves static API definition information. It has no side effects, does not execute code, and does not access system state beyond reading a reference database. The blast radius of misuse is minimal—an AI agent retrieving incorrect or misleading API signatures could at most cause confusion in forensic analysis, not system compromise or data loss.
From the tool's definition Tool name 'api_lookup' and description 'Look up Windows API definition (signature, params, DLL, category)' indicate a query/retrieval operation that returns metadata about Windows APIs. No data is created, modified, deleted, or executed.
Documented attack patterns abuse exactly the kind of access api_lookup gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Windows Forensics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for api_lookup:
{
"version": "1",
"default": "deny",
"tools": {
"api_lookup": {}
}
}api_lookup is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Look up Windows API definition (signature, params, DLL, category). It is categorised as a Read tool in the Windows Forensics MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Windows Forensics MCP Server MCP server in PolicyLayer and add a rule for api_lookup: 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 Windows Forensics MCP Server. Nothing to install.
api_lookup 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 api_lookup 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 api_lookup. 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.
api_lookup is provided by the Windows Forensics MCP Server MCP server (x746b/winforensics-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Windows Forensics MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
