What get_cluster_members does on Fortimanager
AI agents call get_cluster_members 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 get_cluster_members is rated Low
This tool performs a read-only query to retrieve information about HA (High Availability) cluster members. There are no side effects, no code execution, no data modification, and no irreversible actions. The blast radius of misuse is minimal—an attacker could only gain visibility into cluster topology information, which may inform further attacks but does not directly compromise systems.
From the tool's definition Tool name 'get_cluster_members' and description 'Get HA cluster member information' indicate a query operation that retrieves data about cluster members without modifying, deleting, or executing operations.
Attacks that exploit this kind of access
The rule that runs get_cluster_members 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 get_cluster_members, this is the rule to start with:
get_cluster_members 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 get_cluster_members call is checked against it from then on.
Questions about get_cluster_members
Get HA cluster member information. 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 get_cluster_members: 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.
get_cluster_members 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_cluster_members 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_cluster_members. 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_cluster_members 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.
