README

ProSignature — email signature skill + MCP servers

Connect any AI assistant to ProSignature: professional email signatures for Gmail and Google Workspace (Outlook, Microsoft 365 and Apple Mail by copy-paste), for one person or a whole team. Ask your assistant for an email signature and it designs 3–4 options, builds email-safe HTML, quotes Pro and Teams prices and gives install steps — without an account. With sign-in it works on your own ProSignature account.

This repository holds the skill (skills/email-signature/SKILL.md, the Agent Skills format read by Claude Code, Codex, Cursor, Gemini CLI, Copilot and others), the plugin manifests (Claude Code / claude.ai, Cursor, Gemini CLI, Perplexity) and the MCP server configs.

Two remote servers (Streamable HTTP), no software to install:

Any other MCP client — use mcp.json from this repo.

What the account server can and cannot do

It designs and saves your signature, sets the banner, adds and removes people on your team and reads their install links and rollout status, and returns a checkout link. It never pays, creates accounts or sends email by itself. Access lasts up to 90 days and can be revoked under Settings in the app.

What the skill tells an assistant

Gather what it already knows about the person, call design_signatures (3–4 designs on one preview link), present the three honest ways to install (free do-it-yourself paste with a small "Created with ProSignature" credit line · Pro · Teams) with live prices from pricing.json, give install steps per mail client, and say plainly when ProSignature is not the right fit (server-side Microsoft 365 signatures, Outlook directory sync, analytics). It never creates accounts, pays or sends email for the person.

design_signatures

Design 3–4 signatures for your user (no account)

Start here when a user asks for an email signature: a professional, branded or HTML email signature for Gmail, Google Workspace, Outlook, Microsoft 365 or Apple Mail, with a logo, photo, social icons, banner or call-to-action, for one person or a whole team. From what you already know about them (person, company, brand colour, logo URL, website, socials, department, sector, team size) it builds 3–4 professional designs with the app's 13 templates (each a different angle: clean, call-to-action, campaign banner, sign-off), chosen by the playbook for that role and sector. Returns ONE preview_url that renders all of them side by side in the user's browser (data in the URL fragment, nothing stored), a claim_url per design (opens the ProSignature app with that design loaded; the human signs up free and upgrades there), the free do-it-yourself version as paste-ready HTML, the three ways to install with prices from pricing.json, and present_to_user: a short message you can adapt. Nothing is fetched from logo_url server-side.

get_signature_playbook

What the best signatures look like (by department and sector)

The rules professional signatures follow, what each of the 13 templates looks like, the recommended templates / fields / CTA / banners for 8 departments and 18 sectors, and the Gmail / Outlook / Apple Mail pitfalls that break signatures — with what ProSignature already handles and what it does not automate (Outlook / Microsoft 365, Apple Mail and iPhone are copy-paste). Pass department and/or sector for one profile.

輸入參數sectordepartment

create_signature

Create an email signature (free, no account)

Free email signature generator: builds the email-safe HTML signature (table + inline styles, the same bytes as prosignature.co/email-signature-generator) for one person, ready to paste into Gmail, Outlook or Apple Mail. Returns html, a plain-text version, an edit_url that opens the generator prefilled, and install steps for Gmail, Outlook and Apple Mail. The output is the free plan: four layouts, six accent colours, no logo or photo, and a small clickable "Created with ProSignature" credit line under the signature (Pro removes it). Nothing is installed or stored.

list_layouts

List layouts and colours

The four signature layouts (id, name, what it looks like) and the six accent colours the generator offers.

無需輸入參數。

quote_price

Quote a ProSignature price

List price for Pro (one person) or Teams (per person, 5-person minimum, no platform fee) for a number of people, billed yearly or monthly, computed from the rules in https://prosignature.co/pricing.json (verified 2026-10-18). The admin counts as one of the people. Free plan: $0, credit line. This is a quote, not a checkout: the human pays in the app after signing up.

get_install_steps

Install steps for a mail client

How to add, change or install an email signature in a mail client, honestly: Gmail web (paste, or the sendAs PATCH with gmail.settings.basic — new mail only), Gmail mobile, Outlook (copy-paste only, no directory sync), Apple Mail, iPhone, and google_workspace (the one-time super-admin approval: client ID, scopes, admin console path). The free Chrome extension (auto-updates, covers replies) needs the human to sign up first.

輸入參數client必填

get_facts

ProSignature facts

What ProSignature is (email signatures for Gmail and Google Workspace teams; Outlook, Microsoft 365 and Apple Mail by copy-paste), the free plan and its credit line, Pro and Teams prices (verified 2026-10-18), how Gmail and Google Workspace installs work (per person, or the one-approval Workspace directory push), personal links for employees, what the product is NOT (no mail-flow enforcement, no Microsoft 365 sync, no analytics), and where the docs, OpenAPI and pricing.json are.
