WHAT IT DOES

What certificates_list does on Mcp Windows

AI agents call certificates_list to retrieve information from Mcp Windows without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why certificates_list is rated Low

This tool only retrieves certificate information from the Windows certificate store with no side effects, deletion, or execution capabilities. Listing certificates is a passive information retrieval operation. Severity is low because certificate enumeration poses minimal risk unless certificates themselves contain highly sensitive cryptographic material, but the act of listing is non-destructive and read-only.

From the tool's definition Tool name is 'certificates_list' and description states 'List certificates in Windows certificate store' — a read-only query operation that retrieves and displays existing certificate data without modification or execution.

RECOMMENDED RULE

The rule that runs certificates_list safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Windows, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For certificates_list, this is the rule to start with:

certificates_list Allowed

certificates_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Windows, apply this rule, and every certificates_list call is checked against it from then on.
