# Human-in-the-loop email for agents

Pass owner_email on onboard, or add an owner after the inbox exists. That confirmation stays pending until the human confirms. Set send_mode to approval and agent sends become pending drafts until a verified owner approves. Opening the approve or reject link does not decide.

```
# Claude Code

# Cursor (mcp.json)

# or send Authorization: Bearer coop_live_… after onboard:

  "mcpServers": {
    "cooper-email": {
      "url": "https://cooperemail.com/mcp",
      "headers": {

      }
    }
  }
