crea8.one in ChatGPT

Use ChatGPT on the web. OpenAI's current custom-server guide adds the server as a plugin. Authentication there is OAuth, no authentication, or a mix of the two. There is no Bearer header field in that flow, so an API key is placed in the server URL.

1. Open ChatGPT Plugins.
2. Select the plus button, then Add custom MCP server.
3. Name: crea8.one. Server URL: https://mcp.crea8.one/mcp. Authentication: OAuth.
4. Review the warning, select I understand and want to continue, then Create as a plugin.
5. Install the plugin from your plugins list.
6. In the prompt box, type @ and select crea8.one. You can also turn the plugin on for that chat from the app settings.

Name: crea8.one
Server URL: https://mcp.crea8.one/mcp
Authentication: OAuth

Workspace permissions and security restrictions still apply, including Lockdown. Write actions ask you to confirm before they run. You can turn individual tools off from the plugin's details page, and refresh the plugin if the tool list changes.

Source: Add custom MCP server.

Create the key at https://app.crea8.one, under developer / API settings. Add the plugin the same way, with authentication set to No authentication, and put the key in the path. That URL is a secret.

Name: crea8.one
Server URL: https://mcp.crea8.one/mcp/YOUR_API_KEY
Authentication: No authentication

Name crea8.one in the message so ChatGPT uses this plugin. You can ask it to:

• Schedule a social post, including when it should go out.
• Show what is already scheduled.
• Check Stalker for mention monitoring.
• Read or update your Link-in-Bio.

Scheduled posts stay in crea8.one after you close the chat. Confirm a write action before ChatGPT sends it.

ChatGPT is the chat app, and this page is how it connects. Codex is the coding agent. It uses ~/.codex/config.toml and codex mcp add, documented on the MCP page. Both can use the same crea8.one account.
