Signatoro is the agentic email signature platform: save your signature once, and your people and every AI agent you connect use the same one. Connect the Signatoro MCP server and your agent can add your real email signature to the emails it sends, instead of writing its own sign-off or guessing your phone number and title. get_signature returns your saved signature as HTML and text, plus your sender details as structured fields. AI assistants and company agents can have signatures of their own, with an AI disclosure line. Company owners can manage the team's signatures from the agent: list, add and remove members, update a field, resend an invite. Without an account, the agent can make a free signature from a name and details, list the layouts, and give install steps for Gmail, Outlook and other mail apps.

Domain knowledge for Signatoro — workflow patterns, data models, and gotchas for your AI agent.
Signatoro holds the email signature the signed-in person saved. get_signature returns it as html and text, with their sender details as fields, for appending after the body of an email they want signed, in place of a sign-off of your own. When the person's own instructions ask for their signature on every email, or to be asked about it, follow them. For the sender's own details in that email, use only the values in get_signature's sender; if one is missing, leave it out and say so - never guess. If the person has AI assistants or company AI agents with their own signatures, list_signatures lists them; when it is unclear which signature an email should carry, ask before sending. Signed in: update_my_signature changes the signature; company owners can list_members, add_member, update_member_field, remove_member and resend_invite. Without signing in: create_signature makes a free signature from a name and details (give the person its claimUrl: "Open this link to save and edit it in Signatoro."), list_templates lists the layouts, get_install_steps gives the steps for a mail app. Parts a company controls (companyControlled in the result) are changed by its owner on signatoro.com: tell the person which parts and who changes them. remove_member cannot be undone: its first call only proposes the removal; call it again with the confirmation only after the person says yes.

Signatoro is a remote MCP server. The live tool list is supplied by the server when your MCP client connects, so the count is not fixed on this public page. After you connect in MCPBundles Studio or your client, you will see the tools your session can call. A SKILL.md is still included to guide your agent on capabilities and workflows.
