# AI Plugins

### What is an AI plugin?

An AI plugin allows you to extend the capability of a large language model (LLM) using Function Calling (or Tool Use).

BoltAI supports multiple AI plugins: Web Search, Web Browing, AppleScript, Shell Access, FFmpeg...

Starting from v1.34, you can also use any [MCP](https://modelcontextprotocol.io/introduction) server in BoltAI.

### How to use an AI plugin?

When starting a new chat, click on the Plugin and enable the plugins you want to use (screenshot 1).

You can also enable or disable a plugin mid-conversation using the Chat Configuration popover (screenshot 2)

{% hint style="warning" %}
**NOTICE:**

* Some plugins might require a paid API account (Perplexity, Kagi etc.)
* This feature requires the AI model to support  [Function Calling](https://platform.openai.com/docs/guides/function-calling) capability.

The AI model will smartly decide which plugins to use, or not using any at all.

### I don't see the Plugin option. Why?

This feature requires the AI model to support  [Function Calling](https://platform.openai.com/docs/guides/function-calling) capability. If you don't see the Plugin option, it means the AI model you're using doesn't support this capability.

Try switching to a more capable AI model.
