Security & Data Handling

• MCP link is a credential: Your MCP Server URL contains an embedded authentication token. Treat it like a password — do not share it publicly. Regenerate anytime in Settings.
• Media uploads: Video files and thumbnails are uploaded to Boring's Google Cloud Storage to make them accessible for YouTube's API. YouTube requires publicly accessible media URLs for uploads.
• Data flow: Your video, title, description, and media are sent from Boring's server to YouTube's API on your behalf via your connected OAuth token.
• No local credentials: No local API keys or environment variables needed. All auth is embedded in the MCP link.

Prerequisites

1. Sign up at boring.aiagent-me.com with Google
2. Connect YouTube — select the target channel during OAuth
3. Get your MCP link: Go to Settings → copy your MCP Server URL (contains your auth token — treat it like a password)
4. Add to Claude: Paste the MCP link as a Connector — no install, no API key needed

Workflow

Step 1: List Accounts

Call boring_list_accounts and filter for youtube platform.

Step 2: Prepare Video Content

YouTube requires a video file. Gather from the user:

• Video file (required): MP4, MOV, AVI, WMV, FLV — up to 12 hours
• Title (required): Max 100 characters
• Description (optional): Up to 5,000 characters
• Tags (optional): Extracted from hashtags in the description
• Thumbnail (optional): JPG/PNG, min 640x360, max 2MB, recommended 1280x720
• Captions (optional): SRT or VTT file

Step 3: Prepare Media URLs

Upload files to get public URLs:

• Local video: boring_upload_file with file_path
• Video URL: boring_upload_from_url to re-host
• Google Drive: Pass directly

The media_urls array follows a specific order:

media_urls: [
  "https://...video.mp4",           // [0] Video file (required)
  "https://...thumbnail.jpg",       // [1] Custom thumbnail (optional)
  "https://...captions.srt"         // [2] Caption/subtitle file (optional)
]

Step 4: Format the Text Field

YouTube uses a special text format — title and description are separated by a double newline:

text: "My Video Title\n\nThis is the video description. It can be up to 5,000 characters.\n\n#tag1 #tag2 #tag3"

• First line before \n\n = Title (max 100 chars)
• Everything after = Description (max 5,000 chars)
• Hashtags in description are automatically extracted as Tags

Step 5: Publish

Call boring_publish_post:

boring_publish_post(
  account_id="<youtube_account_id>",
  platform="youtube",
  text="Video Title\n\nDescription of the video\n\n#shorts #trending",
  media_urls=["https://...video.mp4", "https://...thumb.jpg"]
)

For YouTube Shorts: Include #shorts in the title or description, and use vertical (9:16) video under 60 seconds.

Step 6: Report

Show:

• Video ID and YouTube URL
• Upload status (processing may take a few minutes on YouTube's side)
• Default visibility is Public
