MCP

DaMail has a built-in MCP server (Streamable HTTP) at https://your-domain/mcp. Agents authenticate with an API key or OAuth.

Create an API key

Section titled “Create an API key”

Create a key under Settings → API keys and choose its permissions and mailboxes. The key starts with dm_ and is shown only once.

Add it to your client

Section titled “Add it to your client”

Claude Code:

终端窗口
claude mcp add --transport http damail https://mail.example.com/mcp \
  --header "Authorization: Bearer dm_xxx"

Claude Desktop, Cursor and others use JSON:

{
  "mcpServers": {
    "damail": {
      "type": "http",
      "url": "https://mail.example.com/mcp",
      "headers": { "Authorization": "Bearer dm_xxx" }
    }
  }
}

Clients that cannot take an API key, such as ChatGPT, sign in with OAuth — see ChatGPT and OAuth.

Permissions

Section titled “Permissions”
Permission Allows Tools
read (always included) Read mail, threads, attachments, drafts, stats, reports and contacts list_accounts list_folders search_emails semantic_search get_email get_thread get_attachment get_stats list_waiting list_subscriptions list_contacts translate_email get_report list_reports list_drafts get_draft
organize Mark read / starred, archive, trash, move, follow-up reminders mark_emails move_emails set_follow_up clear_follow_up
draft Write drafts, reply, forward, submit for approval, cancel create_draft update_draft delete_draft request_send cancel_send
send Send without approval (still with an undo window), unsubscribe send_draft unsubscribe
automation View, dry-run, create, update and delete inbox rules; manage the ignore list; list notification channels (without secrets) list_rules test_rule create_rule update_rule delete_rule list_channels list_ignored_senders ignore_sender unignore_sender
  • Tools a key is not allowed to use are not registered at all, and every call is checked again on the server
  • A key limited to some mailboxes only sees their mail, and can only manage rules that apply to those mailboxes
  • Keys can only change drafts they created; approving or rejecting happens in the web app only
  • Model and notification channel settings contain secrets and can only be managed in the web app

Safety

Section titled “Safety”
  • Approval before sending: mail written by an agent goes to “Pending approval” for you to edit, approve or reject. Only keys with send can send directly, and there is still a SEND_DELAY_SEC undo window
  • Mail is untrusted: the MCP instructions tell agents to treat message bodies as data and never follow instructions inside them
  • Audit log: every API and MCP call is recorded under Audit, filterable by key

With AI analysis enabled, results from get_email, get_thread and search_emails include insight (category, priority, summary and extracted details).
