Integrating Codex with MySQL data via CData CLI

Codex is OpenAI's coding agent that can read, modify, and execute code on your machine, handling multi-file edits, running shell commands, reviewing code changes, and launching Codex Cloud tasks, all through natural language instructions. Its support for integrations, agent skills, and AGENTS.md configuration files makes it well-suited for structured, tool-driven workflows, making it a natural fit for connecting to external data sources through CData CLI.

By describing your data goals in plain language, Codex can handle the full setup process, from driver configuration and license activation to connection creation and query execution, without manual intervention at each step.

This article details step-by-step directions for how to connect MySQL data to Codex through CData CLI.

Prerequisites

1. Codex installed (either Terminal CLI or Desktop)
   • Terminal CLI: CLI – Codex | OpenAI Developers
   • Desktop: App – Codex | OpenAI Developers
2. CData CLI installed
3. Access to MySQL

Step 1: Download the skill (one-time setup)

Always use CData CLI with the official skill.

1. The official CData CLI Skill is available on GitHub and installs through npx skills in the terminal:

   npx skills add CDataSoftware/cli-skills

2. Follow the prompts in the terminal to install for Codex.

Step 2: Set up the project directory

Create a project directory to contain all project files. Below are examples for using Codex in either the Terminal or the Desktop app:

Codex in Terminal CLI

Navigate to the directory within the terminal and start a session with the codex command:

Codex Desktop App

Select the working directory within the desktop app:

Step 3: Establish the driver and connection

Describe what you want to accomplish in this session with the CLI and MySQL data.

I would like to build a command line app that connects to MySQL data and checks for updates from Orders. Make sure to include data from important columns like ShipName and Freight.

This prompt automatically loads the skill and kicks off the following process. You can always manually prompt the agent for each of the following steps.

1. Driver setup: Codex checks for an existing CData MySQL driver, or searches and downloads a new one:

• cdatacli drivers list

• cdatacli drivers search --driver "MySQL"

• cdatacli drivers download --artifact-id <artifact-id>

2. Activation: Activate the MySQL driver with a single command for a trial or full license:

• cdatacli drivers activate "MySQL" --name "<name>" --email "<email>" --trial

• cdatacli drivers activate "MySQL" --name "<name>" --email "<email>" --key "<product-key>"

3. Establish the MySQL connection: Check for existing MySQL connections or create a new one:

• cdatacli connection list

• cdatacli connection create --driver MySQL --name my_mysql_connection --connectionstring "Prop1=value1;Prop2=value2;..."

4. Create a MySQL skill (if applicable): CData provides driver instructions for popular sources. You can use these to generate a source-specific skill file that guides the agent through best practices for the driver.
• Run the following command and save the output to your skills directory, either at the project level or globally. (Note: If you receive a "No instructions available for MySQL" message, no driver instructions exist for this source. You can continue using the main driver skill.)

Step 4: Query MySQL data

With the CData driver fully configured, your agent can now execute queries and write code against live MySQL data:

cdatacli query sql --connection my_mysql_connection --sql "SELECT * FROM Orders"

Query MySQL data directly from your terminal with CData CLI

Codex and CData CLI together give your AI coding agent a direct path to live MySQL data without custom middleware, scheduled syncs, or manual setup at each step. Describe your goal in plain language, and the agent handles driver configuration, connection setup, and query execution from start to finish in the terminal.
