Cline
In the Cline panel open MCP Servers > Configure > Remote Servers, then add:
- Server Name:
mailzzy - Server URL:
https://api.mailzzy.com/crm/mcp/ - Transport Type: Streamable HTTP
Or edit cline_mcp_settings.json directly (Configure > Configure MCP Servers):
{
"mcpServers": {
"mailzzy": {
"type": "streamableHttp",
"url": "https://api.mailzzy.com/crm/mcp/",
"disabled": false,
"autoApprove": []
}
}
}
Sign in with your Mailzzy account when Cline opens the browser. If the server shows an authentication error, remove it and add it again to restart the sign-in. Setup notes written for Cline itself are in llms-install.md.
Any other MCP client
Use the URL with Streamable HTTP transport. The server answers unauthenticated requests with
401 and a WWW-Authenticate header pointing at its
protected resource metadata,
so any client that follows the MCP authorization spec can discover the authorization server and
register itself.
Authentication and permissions
- You sign in on Mailzzy's own login page. Your password is never shared with the AI client.
- The client receives a short-lived access token scoped to your account. Every tool call acts as you and can only see your own account's data.
- Scopes advertised:
mcp:read,mcp:write,mcp:send. - Every tool carries MCP annotations. Read tools are marked read-only. Sending a campaign or transactional email, deleting a contact, and cancelling a campaign are marked destructive, so well-behaved clients ask you to confirm before running them.
- To disconnect, remove the connector in your client.
