Use Codex in the ChatGPT desktop app with the ApexGenius plugin. Connect Salesforce in ApexGenius, authorize the connection Codex may use, and start with one read-only question.

​
Set up in the app

  1. Open Plugins in the ChatGPT desktop app (OpenAI plugin setup guide). Find ApexGenius in the personal or shared plugins available to your account. Install it if needed, or use the personal plugin steps below.
  2. Open ApexGenius and connect when prompted. In ApexGenius, connect the intended Salesforce Production org or Sandbox, then review the connection and access you authorize for Codex.
  3. Return to the app, start a new Codex task, and ask: Which active Flows touch Opportunity?. Check the returned result and the matching successful read in Activity.
A public ApexGenius plugin listing is not verified. Personal and shared plugin availability depends on your account and workspace. Installation alone does not verify Salesforce access.

​
Create a personal plugin

Where your account permits custom connections, open ChatGPT Settings > Security and login and enable Developer mode. In Plugins, select the plus button, enter ApexGenius and a description, then enter https://server.autom8.pro/mcp under Connection. Create the connection, complete OAuth, and review the discovered tools. Return to Codex in the ChatGPT desktop app and start a new task with the plugin enabled. Follow OpenAI’s custom connection guide for your account’s controls.

​
No plugin available? Use desktop settings

  1. In the ChatGPT desktop app, open Settings > MCP servers > Add server.
  2. Name it ApexGenius, select Streamable HTTP, and enter https://server.autom8.pro/mcp.
  3. Choose Save, then Restart, then Authenticate. Complete the ApexGenius sign-in and authorize the connections you want Codex to use.
  4. Start a new Codex task and ask the read-only question above. Check the returned result and its matching successful read in Activity.
See OpenAI’s desktop MCP settings. On the same host, the desktop app, CLI, and IDE extension share MCP configuration. This does not make plugin installation identical across clients.

Codex, ChatGPT, and Work

The journey is the same: find or add ApexGenius, connect, authorize, then return and use Salesforce. Codex coding tasks run in the ChatGPT desktop app. ChatGPT Chat and Work also support plugins. For ChatGPT, open Plugins and follow the custom connection guide when needed. Use the plugin controls available in your selected surface; authorization and workspace policy still apply. ChatGPT web custom apps do not inherit your computer’s Codex configuration. The IDE extension does not support plugin installation.
Codex CLI remains a supported remote MCP option:
Complete the browser authorization, then start a new session. Do not paste a bearer token or static authorization header. Remote MCP configuration is also available for the IDE extension; plugin installation is separate.
See OpenAI’s app plugin guide and remote MCP configuration.
