Adding the Ezurio MCP Server to Codex

Prerequisites:

  • A ChatGPT subscription (Codex is available across all primary plans).
  • The Ezurio MCP Server must be accessible over HTTPS
  • An account at www.ezurio.com.

Overview

ChatGPT Codex supports remote MCP servers through the Integrations panel in settings. You can register the Ezurio MCP to the MCP servers section of Integrations to make its tools available in your ChatGPT/Codex sessions.

Custom Integrations are not verified by OpenAI. Only add MCP servers from sources you trust. An MCP server with write access can modify data in connected systems.

Step 1 – Open Settings

  1. Open the Codex desktop app.
  2. Click your profile name or icon in the bottom-left corner of the sidebar.
  3. Click Settings.
  4. Navigate to Integrations → MCP servers.

Step 2 – Add the Ezurio MCP Server

  1. Click the + Add server button
  2. Enter ezurio-mcp as the MCP server name
  3. Select Streamable HTTP
  4. In the URL field, enter the Ezurio MCP server URL https://mcp.ezurio.com/ez/mcp
  5. Click Save
  6. The ezurio-mcp MCP server now appears in the list of Servers and is enabled by default

Step 3 – Authenticate

  1. In order to authenticate with ezurio-mcp, Codex requires running the login command from a command line. Open a terminal and type the following to connect: codex mcp login ezurio-mcp
  2. The Ezurio MCP user uses OAuth. A browser popup or redirect will appear. Follow the prompts to authorize Codex to access the Ezurio MCP server.
  3. Once authentication completes, restart the Codex desktop application to refresh the connected MCP tools.

Step 4 – Verify

  1. With the connector active, ask Codex a question that would require one of the Ezurio MCP tools.
  2. Codex will invoke the tool automatically and return results from the Ezurio MCP server.

The Ezurio MCP server is now set up. You can enable/disable it from the settings menu.
