## Why vpn_ipsec_phase1_update is rated Medium

IPsec Phase 1 controls VPN tunnel establishment, encryption algorithms, authentication methods, and key exchange parameters. An update tool can modify critical security configurations like encryption standards, peer authentication, or DPD settings. This is Write rather than Execute because it modifies stored configuration data reversibly through the API, not arbitrary code execution.

From the tool's own definition: "Tool name 'vpn_ipsec_phase1_update' indicates modification of IPsec Phase 1 VPN configuration parameters. The '_update' suffix confirms data modification rather than retrieval."

## Use case

AI agents use vpn_ipsec_phase1_update to create or update resources in FortiOS 7 6 X MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FortiOS 7 6 X MCP Server environment.
