MCP server for NarrateAI - get timed transcript from silent video

NarrateAI MCP Server

Add AI video narration, transcription, translation, and dubbing to any AI assistant. NarrateAI's MCP server lets Claude, Cursor, and other MCP-compatible tools process videos through natural conversation.

What You Can Do

• Narrate silent videos — AI writes a timed script and generates voiceover with natural-sounding voices
• Transcribe speech — Extract text from videos with existing audio (meetings, podcasts, lectures)
• Translate transcripts — Translate video transcripts between 11+ languages
• Dub videos — Clone the speaker's voice and re-speak in another language
• Generate documents — Turn screencasts into guides, tutorials, and product docs
• Edit before narrating — Review and refine AI-generated scripts before producing the final video
• Batch process — Narrate, transcribe, or dub up to 5 videos in parallel
• Browse video library — Access and re-use previously processed videos

Quick Start

1. Get an API Key

Sign up at narrateai.app and purchase MCP credits from the API section.

pip install narrateai-mcp

3. Connect to Cursor

Add to your .cursor/mcp.json:

{
  "mcpServers": {
    "narrateai": {
      "command": "narrateai-mcp",
      "env": {

        "NARRATEAI_API_KEY": "your_api_key_here"
      }
    }

• male2, male3

Supported Languages

en, es, fr, de, it, pt, ru, zh, yue, ja, ko — and others via Whisper fallback.

Example Conversations

Narrate a screencast:

"I have a silent demo video. Can you narrate it with the female1 voice?"

Transcribe a meeting:

"Transcribe this meeting recording — it's in Spanish: meeting.mp4"

Dub a video:

"Dub this English video into French, keep the background music"

Generate product docs:

"Create a tutorial guide from this screencast of our new feature"

Translate and re-narrate:

"Take my narrated Messi video, translate it to Hindi, and re-narrate with chatterbox"

Remote / HTTP Mode

For cloud deployments (Smithery, Apify, or self-hosted), run the server in HTTP mode:

narrateai-mcp --transport http --port 8080

The server accepts API keys via the x-api-key HTTP header for remote authentication.

Troubleshooting

• "API key required" — Set NARRATEAI_API_KEY in your MCP config or pass api_key to any tool.
• "Video file not found" — Verify the local file path exists. For remote mode, use get_upload_url first.
• 429 / rate limit — You've used all your MCP credits. Purchase more at narrateai.app.
• Timeout — Long videos may take more time. Use get_job_result to check progress.
