Triggers on check email, send email, search inbox, compose message, list aliases, create landing page, check leads, forward email, manage domain.

Manage your PO6 email aliases, mailbox, and landing pages through natural language.

PO6 gives you short, memorable email addresses like [e-mail] or email on your own domain. This skill connects to the PO6 MCP server so you can manage everything conversationally.

Setup

1. Get a PO6 account and API key

1. Sign up at po6.com
2. Go to Dashboard > Mailbox > API Keys
3. Create a new API key with the scopes you need
4. Copy the key (starts with mcp_po6_)

2. Set your API key

export PO6_API_KEY="mcp_po6_your_key_here"

Or add it to your shell profile (~/.zshrc, ~/.bashrc) for persistence.

3. Add the MCP server

Add to ~/.openclaw/openclaw.json under mcpServers:

{
  "mcpServers": {
    "po6-mailbox": {
      "type": "streamable-http",
      "url": "https://mcp.po6.com",
      "headers": {
        "Authorization": "Bearer ${PO6_API_KEY}"
      }
    }
  }
}

Or run the included setup script:

./scripts/setup.sh

4. Restart OpenClaw

Restart to pick up the new MCP server.

External Endpoints

This skill communicates only with:

• https://mcp.po6.com — PO6 MCP server (all tool calls)

No other external endpoints are contacted.

Security & Privacy

• Secrets handling: Your API key is stored locally in your environment and never logged or sent to third parties. The key is transmitted only in the Authorization header over TLS to mcp.po6.com.
• Server-side hashing: API keys are SHA-256 hashed on the server. PO6 cannot see your key after creation.
• IP allowlists: Optionally restrict key usage to specific IP addresses (CIDR notation supported).
• Key expiration: Keys can be set to auto-expire on a date you choose.
• Confirmation for destructive actions: delete_email, publish_landing_page, unpublish_landing_page, archive_landing_page, and assign_landing_page_domain all require two-step confirmation before execution.
• Audit trail: All API calls are logged and visible in your PO6 dashboard.
• Scope isolation: Keys can be restricted to specific mailboxes and specific scopes, following the principle of least privilege.
• No external storage: No data is stored outside your PO6 account.

Troubleshooting

Error	Fix
PO6_API_KEY not set	Export the variable in the shell that runs OpenClaw. Run echo $PO6_API_KEY to verify.
Authentication failed	Check that your key starts with mcp_po6_ and hasn't expired. Generate a new key from your dashboard if needed.
Rate limited (-32002)	Wait a minute and retry. If you need higher limits, upgrade your plan or contact support.
Insufficient scopes	Your API key lacks permission for that action. Create a new key with the required scopes from your dashboard.
IP not allowed	Your key has an IP allowlist and your current IP is not on it. Update the allowlist in your dashboard.
