What list_system_certificates does on Fortimanager
AI agents call list_system_certificates to retrieve information from Fortimanager without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_system_certificates is rated Low
This tool retrieves system certificates from FortiManager without modifying them. Certificates are sensitive data (can reveal infrastructure, trust chains, and security posture), warranting medium severity even as a Read operation. Confidence is moderate (0.75) due to empty description; it could theoretically involve more complex certificate operations, but the name strongly indicates a list/query function.
From the tool's definition Tool name 'list_system_certificates' indicates retrieval of certificate data. Description is empty, but the naming pattern (list_*) is consistent with Read operations on this server alongside other query-style tools like 'add_*' and 'abort_*'.
Attacks that exploit this kind of access
The rule that runs list_system_certificates safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Fortimanager, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_system_certificates, this is the rule to start with:
list_system_certificates is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Fortimanager, apply this rule, and every list_system_certificates call is checked against it from then on.
Questions about list_system_certificates
list_system_certificates is a read tool on the Fortimanager MCP server. It is categorised as a Read tool in the Fortimanager MCP Server, which means it retrieves data without modifying state.
Register the Fortimanager MCP server in PolicyLayer and add a rule for list_system_certificates: 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 Fortimanager. Nothing to install.
list_system_certificates 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 list_system_certificates 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 list_system_certificates. 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.
list_system_certificates is provided by the Fortimanager MCP server (jmpijll/fortimanager-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
