| VERIFY_SSL | No | Set false to disable certificate checking entirely — prefer PFSENSE_CA_FILE | true |
| API_TIMEOUT | No | Request timeout in seconds | 30 |
| AUTH_METHOD | No | Authentication method: api_key, basic, or jwt | api_key |
| MCP_API_KEY | No | Bearer token for HTTP transport (required for HTTP mode). The server refuses to start with an empty, placeholder or short token | |
| PFSENSE_URL | Yes | pfSense URL (e.g., https://192.168.1.1) | |
| MCP_AUDIT_LOG | No | Path to audit log file (JSON lines) | |
| MCP_BIND_ADDR | No | Docker Compose only: host address the published port binds to | 127.0.0.1 |

| MCP_TRANSPORT | No | Transport mode: stdio or streamable-http | stdio |
| ENABLE_HATEOAS | No | Enable HATEOAS links in API responses | false |
| PFSENSE_API_KEY | No | REST API key (System > REST API > Keys), used when AUTH_METHOD=api_key | |

| PFSENSE_PASSWORD | No | pfSense password (for basic/jwt auth) | |
| PFSENSE_USERNAME | No | pfSense username (for basic/jwt auth) | |

| MCP_ROLLBACK_BUFFER | No | Rollback entries kept in memory | 50 |
