# mail_config Get the current mail/SMTP configuration for system email alerts and notifications. Agent View of the PolicyLayer registry record for `mail_config`. HTML page: https://policylayer.com/tools/spranab-truenas-mcp/mail-config ## Facts - Tool: `mail_config` - Server: Truenas (`spranab/truenas-mcp`) — https://policylayer.com/tools/spranab-truenas-mcp.md - Homepage: https://github.com/spranab/truenas-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "mail_config", "arguments": {} } } ``` ## Why mail_config is rated Low This tool retrieves the existing mail/SMTP configuration settings for system notifications. It performs a query operation with no side effects—it does not create, modify, delete, execute commands, or commit financial transactions. The read-only nature and low sensitivity of SMTP configuration data (containing endpoints and settings but not necessarily credentials) places this in the Read category with low severity. From the tool's own definition: "Tool name 'mail_config' combined with description 'Get the current mail/SMTP configuration' indicates a retrieval operation with the verb 'Get' explicitly stating data retrieval with no modification capability." ## Use case AI agents call mail_config to retrieve information from Truenas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Truenas: ```json { "version": "1", "default": "deny", "tools": { "mail_config": {} } } ``` ## Other tools on Truenas (278) - `acme_dns_authenticator_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/acme-dns-authenticator-delete.md - `alertservice_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/alertservice-delete.md - `api_key_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/api-key-delete.md - `app_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/app-delete.md - `app_rollback` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/app-rollback.md - `boot_attach_disk` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/boot-attach-disk.md - `boot_detach_disk` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/boot-detach-disk.md - `bootenv_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/bootenv-delete.md - `certificate_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/certificate-delete.md - `cloud_backup_abort` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/cloud-backup-abort.md - `cloud_backup_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/cloud-backup-delete.md - `cloudsync_credentials_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/cloudsync-credentials-delete.md - `cloudsync_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/cloudsync-delete.md - `cronjob_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/cronjob-delete.md - `dataset_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/dataset-delete.md - `directory_services_leave` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/directory-services-leave.md - `disk_wipe` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/disk-wipe.md - `group_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/group-delete.md - `initshutdown_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/initshutdown-delete.md - `iscsi_extent_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/iscsi-extent-delete.md - `iscsi_initiator_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/iscsi-initiator-delete.md - `iscsi_portal_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/iscsi-portal-delete.md - `iscsi_target_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/iscsi-target-delete.md - `iscsi_targetextent_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/iscsi-targetextent-delete.md - `keychaincredential_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/keychaincredential-delete.md - `network_interface_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/network-interface-delete.md - `network_rollback_changes` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/network-rollback-changes.md - `network_static_route_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/network-static-route-delete.md - `nfs_share_delete` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/nfs-share-delete.md - `pool_export` — Destructive — https://policylayer.com/tools/spranab-truenas-mcp/pool-export.md - …and 248 more: https://policylayer.com/tools/spranab-truenas-mcp.md ## For agents This record is a snapshot.
