youtube-personal-feed

An MCP server that connects to your personal YouTube account and exposes your subscription feed to AI assistants: list your subscribed channels, list the most recent uploads across your feed, and get https://www.youtube.com/watch?v= links that can be handed off to other MCPs (for example transcript-extraction tools).

Requirements

• Node.js 18+

• A Google account and a Google Cloud project with the YouTube Data API v3 enabled

• An MCP client (opencode, Claude Desktop, etc.)

Related MCP server: YouTube MCP Server

Google Cloud Console setup (one-time)

1. Go to https://console.cloud.google.com and create a project (or reuse one).

2. Enable the API: APIs & Services -> Library -> search "YouTube Data API v3" -> Enable.

3. OAuth consent screen: APIs & Services -> OAuth consent screen.

   • User type: External, then add your own Gmail address as a test user.

   • Add the scope https://www.googleapis.com/auth/youtube.readonly.

4. Create a Desktop client: APIs & Services -> Credentials -> Create credentials -> OAuth client ID -> Application type Desktop app.

   • No redirect URI needs to be registered; loopback redirect is allowed for Desktop clients.

5. Copy the Client ID and Client secret into a .env file at the repo root:

   CLIENT_ID=xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com
   CLIENT_SECRET=GOCSPX-xxxxxxxxxxxxxxxxxxxxxxxx

   (cp .env.example .env first.)

Install and authenticate

Global installation

Install the published package globally to run the CLI and MCP server from any directory:

npm install -g youtube-personal-feed

Create ~/.config/youtube-mcp/.env with your Google Desktop OAuth credentials:

mkdir -p ~/.config/youtube-mcp
cat > ~/.config/youtube-mcp/.env <<'EOF'
CLIENT_ID=xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com
CLIENT_SECRET=GOCSPX-xxxxxxxxxxxxxxxxxxxxxxxx
EOF
chmod 600 ~/.config/youtube-mcp/.env

Authenticate once, then run either executable from any directory:

youtube-personal-feed-auth
youtube-personal-feed subscriptions --limit 20
youtube-personal-feed-mcp

The OAuth token is stored at ~/.config/youtube-mcp/token.json. You can instead provide CLIENT_ID and CLIENT_SECRET as environment variables.

Local development

npm install
npm run auth

npm run auth prints a URL, opens your browser, and asks you to consent. Tokens are stored in ~/.config/youtube-mcp/token.json (read-only to you) and are refreshed automatically at runtime.

Note: because this uses an unverified "Desktop app" client, Google shows a "Google hasn't verified this app" warning the first time. Click Advanced -> Go to (unsafe) to proceed.

Register with an MCP client

• opencode: a project-level .mcp.json is included. It registers the server as youtube-personal-feed with npx tsx src/index.ts. Reopen opencode in this directory to pick it up.

• Claude Desktop: add to claude_desktop_config.json:

  {
    "mcpServers": {
      "youtube-personal-feed": {
        "command": "youtube-personal-feed-mcp"
      }
    }
  }

• Local development: use npx tsx src/index.ts with cwd set to the repository.

Tools

Feed items always include videoUrl in the form https://www.youtube.com/watch?v=<id> — the format accepted by most transcript-extraction MCP servers.

list_feed vs. list_channel_uploads

For example, first call list_subscriptions to obtain a subscribed channel's channelId, then pass it to list_feed:

{
  "channelId": "UCJaGVXG4KgOUXUtcmAHAOdA",
  "limit": 10
}

Use list_channel_uploads with that same ID if the channel is not in your subscriptions, or if you specifically want a direct per-channel lookup.

CLI

The CLI uses the same OAuth credentials and token as the MCP server. Run youtube-personal-feed after global installation, or use npm run cli -- while developing:

youtube-personal-feed subscriptions --query running --limit 20
youtube-personal-feed feed --limit 10 --since-days 7              # all subscriptions
youtube-personal-feed feed --channel-id UCJaGVXG4KgOUXUtcmAHAOdA # one subscription
youtube-personal-feed uploads UCJaGVXG4KgOUXUtcmAHAOdA --limit 15 # any channel
youtube-personal-feed video 64wtzsSQx84

For local development:

npm run cli -- subscriptions --query running --limit 20
npm run cli -- feed --limit 10 --since-days 7
npm run cli -- feed --channel-id UCJaGVXG4KgOUXUtcmAHAOdA --limit 10
npm run cli -- uploads UCJaGVXG4KgOUXUtcmAHAOdA --limit 15
npm run cli -- video 64wtzsSQx84

Each command writes JSON to standard output. Run youtube-personal-feed --help (or npm run cli -- --help) for the command reference.

Quota

The YouTube Data API default quota is 10,000 units/day. List calls cost ~1 unit each. This server caches subscriptions for 30 minutes and per-channel uploads for 10 minutes, so a full feed refresh over ~100 subscriptions costs about 100 units. If you hit the quota, the tools return a clear error; wait until the next day or request more quota.

Development

npm run typecheck   # type-check
npm run lint        # lint and check formatting
npm run format      # apply source formatting
npm run build       # compile to dist/
npm run smoke       # sanity check auth + subscriptions (prints real data)

npm install installs a pre-commit hook. Commits run staged TypeScript files through Biome and then run npm run typecheck. Bypass this only when necessary with git commit --no-verify.
