ClawAIMail - Email for AI Agents

Give your AI agent its own email address. Create inboxes, send and receive real emails, search messages, and manage threads — all through a simple API.

What it does

• Create Inboxes: Instantly create email addresses like [email protected]
• Send Emails: Send real emails from your agent's address
• Receive Emails: Get notified when emails arrive via webhook or WebSocket
• Read & Search: Read messages, search by keyword, track threads
• Manage: Labels, custom domains, and more

Setup

1. Get your API key at https://clawaimail.com (free tier: 3 inboxes, 3K emails/month)
2. Set your environment variable:

CLAWAIMAIL_API_KEY=pb_your_api_key

OpenClaw Configuration

⚠️ Important: Do NOT add mcpServers to openclaw.json — that field is not supported and will crash the Gateway.

Use mcporter (OpenClaw's MCP management tool) to configure:

# Add ClawAIMail as an MCP server
mcporter config add clawaimail "npx -y clawaimail-mcp" --env CLAWAIMAIL_API_KEY="pb_your_api_key"

# Test it works
mcporter call clawaimail.list_inboxes

# Check status
mcporter status

mcporter manages its own config at ~/.openclaw/config/mcporter.json, separate from the OpenClaw Gateway config.

Troubleshooting

MCP Server Configuration (Claude Desktop / Cursor)

For non-OpenClaw MCP clients:

{
  "mcpServers": {
    "clawaimail": {
      "command": "npx",
      "args": ["-y", "clawaimail-mcp"],
      "env": {
        "CLAWAIMAIL_API_KEY": "pb_your_api_key"
      }
    }
  }
}
