Set up ChatGPT

Amperity is published in the ChatGPT plugin directory. Install the plugin, or connect the Amperity MCP server to Codex, sign in with your Amperity credentials, and work with your customer data.

Requirements

Connecting ChatGPT to the MCP server requires:

  • An active Amperity account with access to at least one tenant.

  • Access to ChatGPT with a plan that supports plugins.

Install the Amperity plugin

To install the Amperity plugin:

  1. Open ChatGPT and log in.

  2. Select Plugins from the sidebar, and then search for “Amperity”.

    Note

    A workplace administrator may need to allow plugins for Business or Enterprise plans. Contact your workplace administrator if the Amperity plugin is unavailable.

  3. Select Amperity, and then select Install plugin.

  4. A browser tab opens. Sign in with your Amperity credentials.

  5. Enable the plugin in a chat with an @ mention, or by selecting + and then More.

Set up Codex

Connect the Amperity MCP server to Codex from a terminal.

  1. Add the Amperity MCP server to your Codex configuration:

    codex mcp add amperity --url https://mcp.amperity.com

    Codex registers the server for your user account. The command detects Amperity’s OAuth support and opens a browser window. Sign in with your Amperity credentials to authorize Codex.

  2. Verify that Codex registered the server:

    codex mcp list

    The amperity entry appears as enabled and uses OAuth authentication.

Start interacting with ChatGPT

In a chat with the Amperity plugin enabled, or in a new Codex session, ask:

"Tell me about my Amperity tenant."

ChatGPT or Codex calls the tenant_info tool and returns details about your current Amperity tenant.

Note

Write operations in ChatGPT require a manual-confirm prompt in the chat the first time they are called.
