EM+xby Cubed Studios
MCP connector

The whole document team, inside Claude, ChatGPT, and your agent tools

EM+X is a remote MCP (Model Context Protocol) server. Connect it once and the AI chat you already work in can brief, generate, refine, preview, and download finished, on-brand presentations and documents — without you switching surfaces. Every generation runs the same deterministic quality gates and partner review as the web app, and the result is the same native .pptx or .docx built on your template's own masters.

Connector URL

https://emplusx.com/api/mcp

ChatGPT is the one exception — it connects through its own dedicated URL:

https://mcp.emplusx.com/api/mcp

Authorization uses your EM+X sign-in over OAuth 2.1 — no API keys. The free tier works over MCP, so you can try the whole loop without a card.

What your agent can do

Connect from Claude

  1. Open the EM+X listing in the Claude connectors directory (button below) — or find EM+X in claude.ai under Settings → Connectors.
  2. Click Connect and sign in to EM+X when the authorization screen appears (create a free account if you don't have one).
  3. That one connect covers claude.ai, Claude Desktop, and mobile — same account everywhere.
  4. Ask Claude for a document. The brief assembles itself from your conversation; you confirm it instead of retyping it.

Using the desktop app? Open the listing in Claude Desktop.

Connect from ChatGPT

  1. In ChatGPT, open Settings → Plugins and enable Developer mode if prompted (on some plans it lives under Settings → Security and login).
  2. Back in Plugins, choose MCP → Add → Add MCP Server and paste the ChatGPT connector URL below (ChatGPT has its own URL, different from the standard one).
  3. Authorize with your EM+X sign-in, then ask for a deck or document in the conversation.

Connect from Cursor or another MCP client

Point any MCP-over-HTTP client at the connector URL. For clients configured by file:

{
  "mcpServers": {
    "emplusx": { "url": "https://emplusx.com/api/mcp" }
  }

How do I add EM+X to Claude?

EM+X is a listed connector in the Claude directory: open https://claude.ai/directory/em-x and click Connect - no URL to paste. One connect covers claude.ai, Claude Desktop, and mobile; in the desktop app, claude://claude.ai/directory/em-x opens the listing directly. Authorization runs through your EM+X sign-in (OAuth 2.1).

What is the EM+X MCP connector URL?

The EM+X connector URL is https://emplusx.com/api/mcp for Claude, Cursor, Codex, and other MCP-capable clients. ChatGPT uses its own dedicated URL: https://mcp.emplusx.com/api/mcp. Authorization runs through your EM+X sign-in (OAuth 2.1), with no API keys to manage.

Is the MCP connector free to use?

Yes. The connector works on every plan, including the free tier (one generation plus five revisions per month). Your plan's allowance is shared across the web app and MCP - it is the same account and the same team.

Which AI tools can connect to EM+X?

Any MCP-capable client: Claude (web and desktop), ChatGPT where connectors are supported on your plan, Cursor, and other agent tools that speak the Model Context Protocol over HTTP.

What can an agent actually do over MCP?

Everything the web app can: assemble a brief from the conversation, propose a storyline for approval, generate the document through the full quality-gate stack and partner review, refine it by prompt, preview pages in an interactive panel, compare versions side by side, manage brand templates, and mint expiring download links for the finished .pptx or .docx.
