# Dub Videos With MCP

> Voice-dub a video into 80+ languages with AI voice matching by asking your AI agent through Reap MCP.

> **For AI agents:** a documentation index is at [/llms.txt](/llms.txt). Every page is also available as markdown, just append `.md` to the URL.

## Overview

With Reap MCP connected, your AI agent can dub a video's audio into another language with AI voice matching. Dubbing supports 80+ languages.

If you have not connected Reap yet, start with [Connect Reap MCP Server](/help-center/connect-reap-mcp-server). The examples use Claude, but the same prompts work in any MCP-compatible agent.

<Note>
  Dubbing runs on a video **uploaded** to Reap. Ask your agent to upload the file first.
</Note>

## Dub An Upload

Name the source and target languages — your agent looks up the exact codes Reap needs:

```text theme={"system"}
Upload ~/Videos/launch.mp4 and dub it from English into Spanish.
```

To see what's available first:

```text theme={"system"}
What languages can Reap dub into?
```

## How Your Agent Handles It

<Steps>
  <Step title="It uploads the video">
    Dubbing needs an upload, so your agent uploads your `.mp4` or `.mov` first if it isn't already in Reap.
  </Step>

  <Step title="It resolves the languages">
    You say "English to Spanish"; your agent maps those to the exact source and target language codes Reap expects.
  </Step>

  <Step title="It tracks the job">
    Dubbing runs asynchronously — ask for status anytime, and you'll get an email when it completes.
  </Step>
</Steps>
