Lumail Agent Skills and Plugins

Install Lumail's agent skills or connect Lumail to Claude Code and Codex. The repository includes reusable marketing and copywriting skills alongside the Lumail CLI and OAuth MCP plugin skills.

Agent plugins authenticate with browser OAuth. Those sessions have no API token to create, paste, or store. The WordPress plugin in wordpress/ is the exception: it uses a lum_ organization token on the server.

Install

The fastest path is to let your agent do it. Paste this into Claude Code:

Read lumail.io/claude-code and install the Lumail plugin for me.

or into Codex:

Read lumail.io/codex and set up the Lumail connection for me.

or, for the terminal workflow (full API, including sending), into any agent:

Read lumail.io/cli and set up the Lumail CLI for me.

Prefer to run it yourself:

claude plugin marketplace add https://github.com/Melvynx/lumail-skills.git
claude plugin install lumail@lumail
claude mcp login plugin:lumail:lumail

claude/skills and codex/skills are real copies of skills/ (symlinks break on Windows checkouts), so both hosts ship the same skills. Edit the top-level skills/ first, then sync the copies.

How the connection works

The plugin points both hosts at https://lumail.io/mcp, an OAuth 2.1 protected resource. The host registers itself through dynamic client registration, runs PKCE, and stores the access token itself. During the browser flow you sign in, pick which organization the agent may reach, and approve the scopes. Only owners and admins of an organization can authorize it.

Access tokens carry the organization as a claim, so a session can never reach another organization in your account. Revoke from the connected-apps list in Lumail settings and access stops on the next request, with no local config to clean up.

What agents can do

Read — subscribers, tags, campaigns, campaign analytics and progress, workflows and workflow groups, org stats, subscriber growth, senders, custom fields, snippets, writing style.

Write — add subscribers, create and apply tags, create and edit campaign drafts, duplicate campaigns, create and configure workflow drafts.

Not available over OAuth — sending, scheduling, publishing or activating a workflow, unsubscribing, and every delete. Those tools are not registered on this endpoint, so an agent cannot reach them even with your approval. Do that work in the Lumail app, or with npx lumail if you want it in a terminal.

The CLI

npx lumail reaches the full API, including sending. It authenticates with the same browser flow:

npx lumail auth login

The lumail skill in this repository teaches agents the whole CLI.

WordPress plugin

wordpress/ is a PHP plugin: settings page for a lum_ token, shortcode [lumail_form], server-side POST /api/v2/subscribers. Copy the folder to wp-content/plugins/lumail. Details: wordpress/README.md and wordpress/BUILD.md.

Example prompts

  • How did last week's newsletter perform compared to the one before?
  • Draft a launch campaign with three subject line options.
  • Add user@example.com to my newsletter and tag them vip.
  • Build a three-email welcome sequence over a week and leave it as a draft.
  • Show me subscriber growth over the last 30 days.
