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

What is in here
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.
