Companies try more than one AI agent, or switch which one sends their mail. Because the signature stays in Signatoro rather than inside any one agent, a new Squad, Viktor, Dots, or mailbox does not mean building the signature again - the new agent fetches the same company signature at send time.
An agent fetches one company signature at send time, via https://signatoro.com/mcp or the REST API.
Not a native integration. Not built in, not a marketplace listing, not a company-wide key.
Each agent is its own Signatoro person, with a signature of its own to fetch.
Running more than one AI agent, or more than one mailbox, does not mean a separate signature for each.
