Add this block to any MCP client that supports remote HTTP servers: Use https://mailbox.bot/api/mcp as the server URL and pass your API key in the Authorization header. If your client expects a local command instead of a remote URL, use the command bridge preset.
{ "mcpServers": { "mailbox-bot": { "url": "https://mailbox.bot/api/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } }

Troubleshooting
Client cannot reach the remote server
Switch to the Bridge preset. It runs mcp-remote locally and connects to the same hosted endpoint.
npx or Node is missing
Install Node.js LTS, restart the client, then refresh MCP servers. Command-bridge presets require npx.
Tools do not appear after saving
Restart the client or use its MCP server refresh action. Some clients only load MCP servers at startup.
3. Reload your MCP client
Restart or reload your client so it discovers the mailbox.bot tools. Ask your agent to list packages, request a scan, send facility messages, or create outbound mail.
