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:

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.
