Cue email signature
Cue, the personal agent app from Manus, gives each agent its own email address. Signatoro gives that agent a signature with its name, its role and who it works for.
Cue and its agents
Manus launched Cue with Manus 2.0 on September 28, 2026. Each Cue agent has its own email address, phone number, wallet and computer, sends messages for you and pays within a budget you set. Cue runs on the web, desktop and mobile, in early access with an invite code.
Manus, the general agent, sends from your own Gmail or Outlook. Its page is Manus email signature.
A signature for an agent with its own address
Email from a Cue agent comes from the agent's own address, so it carries an AI assistant signature: the agent's name, its role and the person it works for.
Each AI assistant or agent gets its own key or MCP connection and signs as the person it works for or as itself, by default with a line saying it is an AI and whom it acts for. Free includes 1 AI assistant; each person on a Company plan gets 3 AI assistants, and the company gets 3, 10 or 25 agents by size, on top of the people the plan covers.
- On Signatoro, build your own signature, free.
- Add an AI assistant with your Cue agent's name, and choose "Signs as the agent".
Connect Signatoro to your Cue agent
Cue agents use connectors, custom MCP servers among them. Signatoro tested its MCP server with Manus on October 11, 2026: Manus signed in to Signatoro and fetched the saved signature.
- Add a custom MCP connector with https://signatoro.com/mcp as the server URL.
- Sign in to Signatoro when the agent asks. Then, on your signature page under "Connected assistants", set the connection's "Signs as" to your AI assistant.
- Tell the agent: "Before you send any email, call get_signature and end the email with what it returns."
- Ask the agent to send one email to you, and check that it ends with the signature, once.
Or give the agent an API key
A Cue agent works on its own computer, as a Grok Bot does, and a Grok Bot fetches the signature from the Signatoro API before each email, tested by Signatoro on October 8, 2026.
- On your signature page, generate a key for your AI assistant. That key always returns the assistant's signature.
- Give the agent the key and tell it: "Before you send any email, fetch my signature from https://signatoro.com/api/v1/signature and end the email with it."
- Send one email to yourself and check the bottom.
