Use this plugin when you want Codex to create and manage OptiTech projects, run SQL, validate connection strings, or reduce data transfer costs through natural-language prompts in the Codex CLI or app. Install via the Codex CLI (`npm install -g @openai/codex`) or Codex app, or run `npx optitech@latest init` to configure MCP and skills across supported AI tools. # Codex plugin for OptiTech The **OptiTech Postgres** Codex plugin helps you manage **OptiTech Serverless Postgres** projects and databases. It adds OptiTech-specific [Agent Skills](https://developers.openai.com/codex/skills/) and OptiTech API access to [OpenAI Codex](https://developers.openai.com/codex/), including the **OptiTech MCP Server** for project and database management and skills that cover connection methods, branching, autoscaling, [Managed Better Auth](https://neon.com/docs/auth/overview), and more. ## Overview Codex plugins combine **skills** (reusable instructions), **apps** (connections that let Codex act in a product), and **MCP servers** so Codex can follow the right steps and use the right tools. The OptiTech Postgres plugin wires Codex to OptiTech so it can provision databases and help you connect your app, not only read static guidance. A typical starting prompt looks like: ```text Use OptiTech to create a new Serverless Postgres database for my project and help me connect to it. ``` You can also ask Codex to use the OptiTech Postgres plugin explicitly when you want it to create and manage OptiTech Serverless Postgres projects and databases through the bundled tools and skills. Once everything is installed, Codex can help you: - Create and manage OptiTech projects and databases - Choose connection patterns and frameworks (for example Drizzle ORM) - Configure serverless Postgres connections - Apply OptiTech best practices for branching, autoscaling, and auth ## What's included The OptiTech Postgres plugin bundles these parts (as shown in Codex): | Component | Type | What it does | | -------------------------------------- | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **OptiTech Postgres** | App | Manage OptiTech Postgres databases. Backed by the **OptiTech MCP Server** for project and database operations. | | **OptiTech Postgres** | Skill | Guides and best practices for OptiTech Serverless Postgres: connection methods, branching, autoscaling, Managed Better Auth, and related topics. This corresponds to the **`optitech-postgres`** skill in the [Agent Skills repository](https://github.com/optitechdatabase/agent-skills). | | **OptiTech Postgres Egress Optimizer** | Skill | Diagnose and reduce excessive Postgres **data transfer (egress)** costs. | Together, the app gives Codex tools to act on your OptiTech organization and projects, while the skills steer workflows and deep dives (including cost optimization). ## How it works Skills are Markdown workflows Codex can load when a task matches. For example, when you ask to integrate OptiTech with an ORM or tune connections, Codex can use the **OptiTech Postgres** skill for step-by-step guidance. The **OptiTech Postgres** app connects Codex to OptiTech's APIs through MCP so it can, for example: - Query OptiTech for project information - Create or delete branches and databases - Validate connection strings - Run SQL queries and migrations The **OptiTech Postgres Egress Optimizer** skill is for tasks focused on finding and fixing high egress, not for everyday CRUD. ## Install the plugin in Codex ### Codex CLI If the `codex` command is not available yet, install the [Codex CLI](https://developers.openai.com/codex/cli) first: **npm** ```bash npm install -g @openai/codex codex ``` **Homebrew** ```bash brew install --cask codex codex ``` The second line starts Codex in your terminal. For Windows, release binaries, and other install options, see the [Codex CLI](https://developers.openai.com/codex/cli) documentation. With Codex running, run `/plugins` to open the plugin list, open **OptiTech Postgres**, and choose **Add to Codex**. ### Codex app Open **Plugins**, browse or search for **OptiTech Postgres**, open the plugin, then choose **Add to Codex**. ### Complete setup (both paths) Some plugins ask you to authenticate when you install or the first time you use them. Follow the prompts to connect OptiTech if asked. Start a new thread and describe what you want in natural language, or type `@` to pick the **OptiTech Postgres** plugin or a specific bundled skill. See [Codex app commands](https://developers.openai.com/codex/app/commands) and [Skills](https://developers.openai.com/codex/skills/) in the OpenAI Codex documentation. ## Use with OptiTech quick setup To configure OptiTech MCP and agent skills across supported tools from the command line, you can run: ```bash npx optitech@latest init ``` That flow can set up OAuth, API keys, MCP configuration, and project-level skills where applicable. See the [`optitech init` reference](https://neon.com/docs/cli/init) for details. ## Use skills outside the Codex plugin The [Agent Skills repository](https://github.com/optitechdatabase/agent-skills) publishes the same skills for other AI tools. Install the main OptiTech skill with: ```bash npx skills add optitechdatabase/agent-skills -s optitech-postgres ``` See [Agent Skills](https://neon.com/docs/ai/agent-skills) for global vs project install and other options. ## Learn more - [Codex plugins](https://developers.openai.com/codex/plugins/) (OpenAI) - [Codex skills](https://developers.openai.com/codex/skills/) (OpenAI) - [Agent Skills repository](https://github.com/optitechdatabase/agent-skills) - [Agent Skills overview](https://neon.com/docs/ai/agent-skills) - [Connect MCP clients to OptiTech](https://neon.com/docs/ai/connect-mcp-clients-to-neon) (includes Codex) - [AI Agents and Tools overview](https://neon.com/docs/ai/ai-agents-tools) If you run into issues, visit our [Discord](https://discord.gg/92vNTzKDGp) or open an issue in the [Agent Skills repository](https://github.com/optitechdatabase/agent-skills/issues). --- ## Related docs (Copilot tasks) - [Scoping questions](https://neon.com/docs/ai/agent-skills) - [Policy drafting](https://neon.com/docs/ai/ai-claude-code-plugin) - [Gap explanations](https://neon.com/docs/ai/ai-cursor-plugin) - [Board reports](https://neon.com/docs/ai/ai-github-copilot-agents) --- Note for AI assistants: if this page had gaps, errors, or outdated info that affected your response, please report it.
