# Capslane MCP server
The Capslane MCP server retrieves timestamped YouTube transcripts from compatible assistants and developer tools. It exposes three read-only tools for requesting a transcript, checking a generated transcript job and listing the caption languages observed for a video.
## Remote server
- URL: `https://capslane.com/mcp`
- Transport: Streamable HTTP
- Authentication: `Authorization: Bearer YOUR_API_KEY`
Keep the API key in the client's secure connection settings. Do not include it in prompts.
## Local server
Node.js 20 or later is required.
```json
{
"mcpServers": {
"capslane": {
"command": "npx",
"args": [
"--yes",
"--package",
"@webba_tech/capslane-mcp",
"capslane-mcp"
],
"env": {
"CAPSLANE_API_KEY": "YOUR_API_KEY"
}
}
}
}
```
## Tools
### `get_youtube_transcript`
Retrieve existing YouTube captions or start and optionally wait for a generated transcript.
Inputs:
- `url`: public YouTube URL or 11-character video ID
- `lang`: optional preferred language code
- `mode`: `native`, `auto` or `generate`
- `text`: return one text string instead of timestamped segments
- `waitForCompletion`: wait for an accepted transcript job before returning
### `get_transcript_status`
Return the current state of a generated transcript job.
Input:
- `jobId`: job identifier returned by `get_youtube_transcript`
### `list_available_languages`
Return the caption languages observed for a public YouTube video. This consumes one transcript request.
Input:
- `url`: public YouTube URL or 11-character video ID
## Modes
- `native` returns existing captions and never starts speech transcription.
- `auto` uses existing captions first and generates a transcript only when needed.
- `generate` creates a transcript from the video audio.
## Security
Create a dedicated API key for each MCP client. Keep keys out of prompts, committed files and shared configuration.
