## Introduction

Grok is xAI's assistant, and its bot builder lets you create a personal agent that holds context, runs skills, and connects to the apps you already use through plugins.
This guide explains how to connect Captions to a Grok bot using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a plugin, authenticate once, then ask your bot to work with Captions in plain language.

## Also integrate Captions with

- [ChatGPT](https://composio.dev/toolkits/captions/framework/chatgpt)
- [Claude Cowork](https://composio.dev/toolkits/captions/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/captions/framework/hermes-agent)
- [Atomic Agent](https://composio.dev/toolkits/captions/framework/atomic-agent)

## TL;DR

Composio exposes 1,500+ apps to your Grok bot through a single connection, so you get:
- Connect to 1,500+ apps with on-demand tool loading, so you do not fill your context window with unnecessary tool definitions.
- Use programmatic tool calling through a remote workbench, letting the model write its own code to handle complex tool chaining. This reduces back-and-forth for frequent tool calls.
- Handle large tool responses outside the model context to keep conversations lean.

## Connect Captions to Grok Bot

### Connecting Captions to Grok Bot
Once Grok Bot is set up, you connect Captions entirely from its interface, and the whole flow takes under a minute.
### Set up Grok Bot
Get access. Grok Bot is included with Cursor Ultra, Cursor Premium Teams, and SuperGrok Heavy. Get the desktop app for macOS or Windows from [x.ai/bot](https://x.ai/bot) and sign in. An iPhone companion app is also available, and your bots sync across devices.
Create a bot. Pick a suggested role or define your own, then give it a short name, one primary job, and a short description of how it should work. Focused bots work best, because a clear role gives the bot more useful context over time.
### Connect Captions
### 1. Add the Composio plugin
Click the button. The Composio listing on x.ai opens and launches Grok Bot for you. If the app does not open on its own, click Add to Grok Bot.
[Add to Grok Bot](https://x.ai/bot/plugin/32661537)
Grok Bot opens the Composio plugin, showing its connector and skills. Click Add.
### 2. Authenticate
Go to the Installed section and click the Composio entry. You'll see its connector and skills listed.
Click Authenticate. You'll be taken to the Composio consent screen. Review the access it requests and click Authorize. Composio handles the OAuth handshake for you, so you never touch API keys or tokens.
### 3. Connect your Captions account
Back in the chat, ask your bot to connect to Captions or give it any Captions task.
For example, ask it to:
- "Generate narrated product demo video"
- "Add styled captions to your video"
- "Create voiceover for training clip"
It will prompt you to authenticate and authorize access.
That's it. Composio's tools are now available in your Grok bot, and your Captions account is ready to use.

## What is Grok Bot?

Grok is xAI's assistant, available as a chat interface and a bot builder for creating personal agents that run skills and connect to external apps.
With Composio Connect, your Grok bot can securely access apps like Captions through MCP without you sharing account credentials directly with the agent.

## What is the Captions MCP server, and what's possible with it?

The Captions MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Captions account. It provides structured and secure access to Mirage video, speech, and caption tools, so your agent can generate speech, create videos, add styled captions, track progress, and download completed videos on your behalf.
- Speech generation: Have your agent turn written scripts into WAV speech using a known Mirage voice.
- Portrait video creation: Direct your agent to animate a portrait image with speech audio and create a video.
- Styled video captions: Let the agent browse available caption styles, review a chosen style, and add it to a video.
- Job tracking: Instruct your agent to check video generation and captioning progress, including any errors that need attention.
- Video library and downloads: Have your agent list your video jobs and download completed videos as MP4 files.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CAPTIONS_ADD_CAPTIONS` | Add Captions | Start an asynchronous job that transcribes and renders a selected caption style onto an uploaded or existing completed video. Use CAPTIONS_GET_VIDEO_STATUS to monitor the returned job, then CAPTIONS_DOWNLOAD_VIDEO when it completes. This call consumes paid Mirage credits and cannot be cancelled or deleted once submitted. |
| `CAPTIONS_DOWNLOAD_VIDEO` | Download Video | Download the MP4 content of a completed video job and return an offloaded file reference. Use CAPTIONS_GET_VIDEO_STATUS first to confirm the job is COMPLETE. |
| `CAPTIONS_GENERATE_SPEECH` | Generate Speech | Generate WAV speech synchronously from text using a known Mirage voice ID and return an offloaded audio file reference. This call consumes paid Mirage credits and cannot be cancelled or deleted once submitted. |
| `CAPTIONS_GENERATE_VIDEO` | Generate Video | Start an asynchronous Mirage Video 1 job that animates a portrait image using speech audio. Use the returned job ID with CAPTIONS_GET_VIDEO_STATUS. This call consumes paid Mirage credits and cannot be cancelled or deleted once submitted. |
| `CAPTIONS_GET_CAPTION_TEMPLATE` | Get Caption Template | Retrieve one caption style by ID, including its name and preview video URL. |
| `CAPTIONS_GET_VIDEO_STATUS` | Get Video Status | Retrieve the current state, progress, and error details for a video generation or captioning job. |
| `CAPTIONS_LIST_CAPTION_TEMPLATES` | List Caption Templates | Return one page of available caption styles, including names and preview video URLs. |
| `CAPTIONS_LIST_VIDEOS` | List Videos | Return one page of video jobs owned by the connected Mirage account, including each job's status and progress. |

## Creating MCP Server - Stand-alone vs Composio SDK

Once connected, your Grok bot can access the Captions MCP server through Composio to run the actions you authorize, using plain language in the chat.

## Complete Code

None listed.

## Conclusion

### Way Forward
Now that Captions is connected, extend your setup by connecting the other apps you already use every day, so your Grok bot can run true cross-app workflows end to end.
- Connect Calendar to turn threads into scheduled meetings automatically.
- Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
- Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
- Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.
Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, your bot can coordinate multiple tools safely and reliably in one conversation.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Captions MCP?

With a standalone Captions MCP server, the agents and LLMs can only access a fixed set of Captions tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Captions and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Grok Bot?

Yes, you can. Grok Bot fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Captions tools.

### Can I manage the permissions and scopes for Captions while using Tool Router?

Yes, absolutely. You can configure which Captions scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Captions data and credentials are handled as safely as possible.
