Find firewall policies that reference address objects containing an IPv4 address.
AI agents call fortigate_find_policy_by_ip 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 performs a search/query operation across firewall policy configurations to locate policies associated with a given IP address. It is read-only data retrieval with no side effects, state changes, or code execution. The blast radius of misuse is minimal — an attacker could only learn which policies reference certain IPs, which is informational only and does not alter the firewall state or security posture.
From the tool's definition Tool name includes 'find' and description states it 'Find[s] firewall policies that reference address objects' — a query operation. Server description emphasizes 'read-only querying and diagnostics' and 'configuration inspection'.
Attacks that exploit this kind of access
Find firewall policies that reference address objects containing an IPv4 address. 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_find_policy_by_ip: 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_find_policy_by_ip 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_find_policy_by_ip 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_find_policy_by_ip. 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_find_policy_by_ip 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.
