# Gemini CLI Extension

The official Pinecone extension for [Gemini CLI](https://github.com/google-gemini/gemini-cli) provides AI-powered skills and MCP server integration directly in your terminal. Use natural language to manage indexes, query data, build RAG applications, and create document Q\&A assistants.

## Features

- **7 built-in skills** for index management, semantic search, assistant creation, and more
- **MCP server integration** for direct Pinecone operations from Gemini CLI
- **Natural language activation** — just describe what you want and the right skill is invoked automatically

## Prerequisites

- A [Pinecone API key](https://app.pinecone.io/organizations/-/keys)
- [Gemini CLI](https://github.com/google-gemini/gemini-cli) installed
- [uv](https://docs.astral.sh/uv/getting-started/installation/) installed (required for skill scripts)
- [Pinecone CLI](/guides/cli-quickstart) installed (optional, for advanced operations)

## Installation

::::steps
:::step{title="Set your API key"}
```shell theme={null}
export PINECONE_API_KEY="YOUR_API_KEY"
```

Replace `YOUR_API_KEY` with your [Pinecone API key](https://app.pinecone.io/organizations/-/keys).
:::

:::step{title="Install the extension"}
```shell theme={null}
gemini extensions install https://github.com/pinecone-io/gemini-cli-extension
```
:::

:::step{title="Restart Gemini CLI"}
Restart Gemini CLI to activate the extension. Then ask:

```text theme={null}
Use the help skill to show me what Pinecone skills are available.
```
:::
::::

:::callout{intent="note"}
If you hit API key errors, exit Gemini CLI, run `export PINECONE_API_KEY="your-key"` in your terminal, and start Gemini CLI again. The CLI only reads environment variables at launch.
