Claude, ChatGPT, and Grok can all connect to your social media accounts now — not through a browser extension or copy-pasting drafts, but through MCP, a protocol that lets an AI assistant call tools directly. Here's how each connection works with OneUp specifically.

## The shared foundation: OneUp's MCP server

All three connections rely on the same underlying piece: OneUp's MCP server, authenticated with an API key generated from your OneUp account (gear icon → **API and MCP**). Each AI tool connects to that same server slightly differently, based on how that platform handles custom connectors.

## Connecting Claude

1. Open Claude and go to **Settings → Connectors**.
2. Click **Add Custom Connector**.
3. Find the OneUp MCP setup endpoint in the API documentation, and append your API key to the connector URL as instructed.
4. Save — OneUp now appears as an active connector, ready to draft, schedule, and publish from a chat prompt.

## Connecting ChatGPT

1. Open ChatGPT and go to the **Plugins** menu.
2. Create a new custom plugin and name it (e.g., `OneUp`).
3. Grab OneUp's MCP connector URL from the API docs (under ChatGPT Setup) and paste it into the plugin config, leaving authentication set to OAuth.
4. Sign in on the plugin popup, generate your OneUp API key from a separate tab, paste it in, and authorize.
5. In **Installed Plugins**, set permissions to **Allow all actions** so ChatGPT doesn't block scheduling workflows mid-conversation.

## Connecting Grok

1. Open Grok and go to **Plugins → New Connector → Add a custom connector**.
2. Name it, and for the Server URL, use OneUp's MCP connector URL with your API key appended.
3. Grok connects and can now be prompted to sync content, schedule posts, or run recurring automations — this is also the specific path required if you want X (Twitter) content flowing into OneUp, since X isn't a source OneUp's own dashboard supports directly.

## What you can actually do once connected

Regardless of which assistant you're using, the same core capabilities are available: drafting and scheduling posts, publishing across multiple platforms, fetching analytics, and replying to comments — all triggered by a prompt instead of clicking through a dashboard.
