Email Signature Gen for AI assistants

Create, roll out and update HTML email signatures for your whole team from your AI assistant.

Email Signature Gen builds on-brand HTML email signatures and hosts them, so one change updates everyone. From your AI tool it can read your brand from your website, make a signature for each person, send no-login install links, and schedule banners. $1 per person a month; custom domains and banners are add-ons.

This package holds:

  • The skill: skills/email-signature-gen/SKILL.md. It gives your assistant the steps and rules for rolling out signatures.
  • The MCP server address: mcp.json and .mcp.json. They point at https://emailsignaturegen.com/api/mcp/core.
  • Plugin manifests: for Agent Plugins, Cursor and Claude Code.

There is nothing to run. The package is Markdown and JSON.

What it does

The core address has 26 tools for rolling out a team's signatures:

  • Find your organization and plan.
  • Read your brand from your website, then save it once you confirm.
  • Add people one at a time or from a spreadsheet.
  • Make a signature for each person in one of ten layouts, or in a layout your assistant designs and saves for your organization.
  • Send each person a link that installs their signature in Gmail, Outlook or Apple Mail, with no login.
  • Update details or the layout later, and see who still needs to reinstall.

Your assistant asks before anything that sends email, changes many signatures at once, or deletes something.

For banners, teammates and web addresses, use the full address, https://emailsignaturegen.com/api/mcp, and tick those permissions when you connect.

Install

Each app signs you in through your browser on the first call. You approve what it can do on an Email Signature Gen page. You never paste a password, token or API key into the app.

skills.sh (Claude Code, Codex, Cursor and other agents)

npx skills add teton-web/email-signature-gen

This adds the skill. Your app also needs the MCP server, so add it with the steps for your app below. More: emailsignaturegen.com/mcp

Claude Code

Add this repository as a plugin marketplace and install the plugin. The plugin brings both the skill and the server.

claude plugin marketplace add teton-web/email-signature-gen
claude plugin install email-signature-gen@email-signature-gen

Then type /mcp in Claude Code, pick email-signature-gen, and choose Authenticate. More: emailsignaturegen.com/mcp

Cursor

Once the plugin is listed on cursor.directory, install it there. Or add the server yourself in ~/.cursor/mcp.json:

{ "mcpServers": { "email-signature-gen": { "url": "https://emailsignaturegen.com/api/mcp/core" } } }

Then sign in from the server's entry in Cursor's MCP settings. The core address keeps you well under Cursor's tool limit. More: emailsignaturegen.com/mcp

Codex

codex mcp add email-signature-gen --url https://emailsignaturegen.com/api/mcp/core

Codex opens your browser to sign in. If it doesn't, run codex mcp login email-signature-gen. Add the skill with skills.sh. More: emailsignaturegen.com/mcp

Hermes

hermes mcp add email-signature-gen --url https://emailsignaturegen.com/api/mcp/core --auth oauth

Sign in when your browser opens, then choose which tools to turn on. More: emailsignaturegen.com/mcp

Claude and ChatGPT connectors

Add a custom connector with the address https://emailsignaturegen.com/api/mcp, then connect and sign in. The steps for each app are at emailsignaturegen.com/mcp.

What you allow

On a first connection the app can:

  • See the people in your organizations who have email signatures
  • Add, edit, delete, and import those people
  • See email signatures, layouts, the brand kit, and install status
  • Create, edit, and delete email signatures, layouts, install links, and the brand kit
  • See banner images and campaigns

These stay off unless you tick them on the sign-in page:

  • Add banner images and schedule, publish, or pause campaigns
  • Invite teammates, change their roles, and remove them
  • Create and rename organizations and set up their web address

The app never gets more than your role in each organization allows. It can't change billing or the plan, delete or hand off an organization, or set anyone's password.

Disconnect

In the Email Signature Gen dashboard, open Connected apps and click Revoke next to the app. It stops working at once.

Pricing
