Capabilities

Tools 11

add_member

Invite a person to the company by email, with their name, title and phone for their signature. They get an email with the invitation and their signature. Counts toward the company plan's people limit. Company owners only. For someone already in the company, use update_member_field; to send an invitation again, use resend_invite.

Discovered
create_signature

Make a free email signature from a name and optional title, company, phone, email, website, LinkedIn, layout and accent color. Returns the signature as HTML (for the HTML part of an email or a signature box that takes HTML) and as plain text, plus claimUrl, a link that opens it in Signatoro with these details and layout to save and edit. Nothing is saved and no account is needed; always give the person claimUrl with: "Open this link to save and edit it in Signatoro." To save a signature to the signed-in person's Signatoro account ("create my signature", "save it"), use update_my_signature instead; for the signature they already saved, use get_signature.

Discovered
get_install_steps

Get the steps to add an email signature in a mail app or tool, from Signatoro's install guides, with the link to the full guide. Pass the app as client, e.g. "gmail", "outlook-new", "outlook-classic", "apple-mail", "ios-mail", "zoho-mail", "thunderbird". An unknown client answers with the list of guides there are.

Discovered
get_signature

Returns the signed-in person's saved email signature as html and text, with their sender details as fields in sender, for appending to an email they want signed. Append it after the body, in place of a sign-off of your own. For the sender's own details anywhere in the email (name, title, phone, email, links), use only the values in sender; if one is missing, leave it out and say so - never guess. mode "short": name, role line and one link. signature: "me" (default), or an AI assistant or company AI agent from list_signatures; if it is unclear which this email needs, ask before sending. To change the signature, use update_my_signature. Parts the company controls are listed in companyControlled, with who changes them in howToChange; tell the person.

Discovered
list_members

List the people in the signed-in owner's company: joined members and pending invitations, with name, title, phone, status (joined, invited, expired) and whether their signature is installed. Company owners only. Omit company to list every company you own.

Discovered
list_signatures

Lists the signatures the signed-in person can send email with: their own ("me", the default), their AI assistants', and company AI agents' (agents of a company they own or that acts for them) - each with id, name, how it signs (as the person or as the agent), its AI disclosure preset and a one-line preview. Pass a choice as signature to get_signature. If it is unclear which one the person wants for an email, ask them before sending. A connection bound to one agent lists only that agent.

Discovered
list_templates

List the signature layouts Signatoro offers, each with a short description of what it shows and when it fits best. Pass a layout id to create_signature.

Discovered
remove_member

DESTRUCTIVE and cannot be undone: removes a person from the company. A joined member loses access to the company and its signature; a pending invitation is withdrawn with the details entered for it. Two steps: called without confirmation it removes nothing and returns who would be removed and a confirmation. Show that to the person, and only after they say yes call again with the confirmation; it expires in 10 minutes. Company owners only. Nobody can remove themselves or the primary owner.

Discovered
resend_invite

Send the invitation email again to a person invited to the company who has not joined yet, renewing it for 7 days if it expired. Company owners only.

Discovered
update_member_field

Change one field (name, title or phone) of a person's signature in the company. A joined member gets an email with their updated signature; for someone still invited, the invitation is sent again with the new details. Company owners only.

Discovered
update_my_signature

Save or change the signed-in person's own signature on Signatoro: name, title, phone, address, email, website, LinkedIn, extra link, photo, review badge, booking button, layout, color and font. With nothing saved yet, this creates the signature. Give only the fields to change; the rest keep their saved values, and "" clears a field. Company brand items (logo, company colors, the company review badge or booking button) are set by the company owner on signatoro.com: fields the company controls are left unchanged and listed in ignored, with who changes them; tell the person. A connected mailbox (Zoho Mail) gets the new signature. Returns the updated signature as HTML and text with sender, the details as fields, and counts as one signature request like get_signature; with the month used up, the change is saved and the signature held back. When nothing changed, nothing is written or counted.
