# list_domains List domains on the TrekMail account. Supports filtering by status and searching by name. Returns paginated results. Agent View of the PolicyLayer registry record for `list_domains`. HTML page: https://policylayer.com/tools/trekmail-mcp-server/list-domains ## Facts - Tool: `list_domains` - Server: TrekMail MCP Server (`trekmail/mcp-server`) — https://policylayer.com/tools/trekmail-mcp-server.md - Homepage: https://github.com/trekmail/mcp-server - 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": "list_domains", "arguments": {} } } ``` ## Why list_domains is rated Low This tool retrieves and queries domain information from the TrekMail account without performing any side effects, modifications, or state changes. It is a straightforward read operation that falls squarely into the Read category with low severity, as unauthorized access to domain listings poses minimal risk compared to write, execute, or destructive operations. From the tool's own definition: "Tool description explicitly states 'List domains' and 'Returns paginated results', indicating a data retrieval operation with filtering and search capabilities but no modification or execution of actions." ## Use case AI agents call list_domains to retrieve information from TrekMail MCP Server 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 TrekMail MCP Server: ```json { "version": "1", "default": "deny", "tools": { "list_domains": {} } } ``` ## Other tools on TrekMail MCP Server (247) - `bulk_action` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/bulk-action.md - `cancel_bulk_migration` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/cancel-bulk-migration.md - `cancel_migration` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/cancel-migration.md - `cancel_scheduled` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/cancel-scheduled.md - `change_mailbox_password` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/change-mailbox-password.md - `confirm_delete_intent` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/confirm-delete-intent.md - `create_delete_intent` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/create-delete-intent.md - `delete_alias` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-alias.md - `delete_bulk_migration` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-bulk-migration.md - `delete_calendar_event` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-calendar-event.md - `delete_cloudflare_token` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-cloudflare-token.md - `delete_contact` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-contact.md - `delete_contact_group` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-contact-group.md - `delete_domain` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-domain.md - `delete_domain_smtp_profile` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-domain-smtp-profile.md - `delete_external_account` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-external-account.md - `delete_folder` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-folder.md - `delete_forwarding_address` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-forwarding-address.md - `delete_identity` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-identity.md - `delete_mail_rule` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-mail-rule.md - `delete_message` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-message.md - `delete_migration` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-migration.md - `delete_smtp_connection` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-smtp-connection.md - `delete_template` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/delete-template.md - `drive_bulk_purge` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/drive-bulk-purge.md - `drive_bulk_trash` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/drive-bulk-trash.md - `drive_device_revoke` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/drive-device-revoke.md - `drive_file_purge` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/drive-file-purge.md - `drive_file_trash` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/drive-file-trash.md - `drive_folder_purge` — Destructive — https://policylayer.com/tools/trekmail-mcp-server/drive-folder-purge.md - …and 217 more: https://policylayer.com/tools/trekmail-mcp-server.md ## For agents This record is a snapshot.
