What is the MailerPress Pro MCP server?
The MailerPress Pro MCP server from AcrossAI lets Claude, ChatGPT, Cursor and any other MCP client manage segments, custom fields, webhooks, embed keys and WordPress and WooCommerce email templates on your WordPress site. It runs inside WordPress through AcrossAI Pro, on top of the free Abilities Manager and MCP Manager plugins, and works through MailerPress Pro itself — with no third-party relay in between.

What your AI can do with MailerPress Pro
MailerPress Pro adds segments, contact custom fields, webhooks, embed keys and branded WordPress and WooCommerce emails. These abilities let an AI assistant build segments, wire up webhooks and manage those email templates — through MailerPress Pro itself.
Segments
Create and update segments, see their conditions and list the contacts in each.
Contact custom fields
Create, update and remove the custom fields stored on contacts.
Webhooks and embed keys
Manage outgoing webhooks, see the events they can send, and manage embed keys.
WordPress and WooCommerce emails
Save branded templates for WordPress and WooCommerce emails and send tests.
Troubleshooting
Segment or email not behaving? Three things AI can check.
Each of these fails quietly — nothing errors, the wrong people just get the wrong email.
A segment returns no one
Contacts In A Segment shows who matches, and the condition metadata shows what the rules can filter on.
A webhook never fires
Outgoing Webhook Settings and the event catalogue show what is switched on and which events exist.
A store email looks wrong
Send Test WooCommerce Email shows the template exactly as customers will see it.
Try asking
Paste one into Claude, ChatGPT or Cursor once your site is connected.
“Create a segment of contacts who bought in the last 30 days.”
“How many contacts are in the ‘Inactive’ segment?”
“Add a ‘Company size’ custom field to contacts.”
“Send new subscribers to our CRM webhook.”
“Send me a test of the WooCommerce order-completed email.”
“List every embed key and where it’s used.”

MailerPress Pro + AI questions
Is there an MCP server for MailerPress Pro?
Yes. AcrossAI turns your WordPress site into an MCP server with 28 dedicated MailerPress Pro abilities, so Claude, ChatGPT, Cursor or a local model can work with MailerPress Pro directly. The MailerPress Pro abilities ship in AcrossAI Pro.
Can ChatGPT or Claude manage MailerPress Pro?
Yes, once your site is connected over MCP. Ask in plain English and your AI calls the MailerPress Pro abilities on this page, with risky changes gated behind an explicit confirm.
Is the MailerPress Pro integration free?
No. The MailerPress Pro abilities ship in AcrossAI Pro, from $99 a year for one site, and every plan starts with a 30-day free trial. Abilities Manager and MCP Manager, which it runs on, stay free on WordPress.org.
Do I also need the MailerPress integration?
They work together: the MailerPress integration covers campaigns, contacts, lists and workflows, and this one adds MailerPress Pro’s own features. Both ship in AcrossAI Pro.
Can the AI delete segments or webhooks by accident?
Deleting segments, custom fields, webhooks, embed keys and email templates are clearly labelled destructive abilities, and the riskiest ask for explicit confirmation.
Which AI assistants work with it?
Any MCP client: Claude, ChatGPT, Gemini, Grok, Cursor, Claude Code, and local runtimes such as Ollama, LM Studio and Open WebUI.
Does my site data pass through AcrossAI’s servers?
No. Your WordPress site runs the MCP server and your AI client connects to it directly. There is no hosted gateway in the middle.
Is AcrossAI affiliated with MailerPress Pro?
No. AcrossAI built and maintains this integration independently, using MailerPress Pro’s public APIs.
