Run 'show firewall policy' on the Fortigate and return firewall policy configuration.
AI agents call fortigate_get_firewall_policies to retrieve information from Fortigate MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves firewall policy data from the Fortigate device through a read-only command. It has no side effects, cannot modify configurations, and only inspects existing state. This is a straightforward Read operation with low severity because misuse would only expose configuration information that an administrator should understand before granting access, and viewing policies does not cause operational harm.
From the tool's definition Tool description states 'show firewall policy' which is a read-only query command. The server description emphasizes 'read-only querying and diagnostics' with 'configuration inspection'.
Attacks that exploit this kind of access
Run 'show firewall policy' on the Fortigate and return firewall policy configuration. It is categorised as a Read tool in the Fortigate MCP MCP Server, which means it retrieves data without modifying state.
Register the Fortigate MCP server in PolicyLayer and add a rule for fortigate_get_firewall_policies: 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 Fortigate MCP. Nothing to install.
fortigate_get_firewall_policies 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 fortigate_get_firewall_policies 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 fortigate_get_firewall_policies. 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.
fortigate_get_firewall_policies is provided by the Fortigate MCP server (picaresco/mcp-fortigate). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
