Braintube

Save once. Query anywhere. BrainTube compiles what you watch, read and listen to — YouTube videos, podcasts, articles, PDFs — into a persistent, searchable knowledge base, and this MCP server exposes it to every MCP-capable AI client over one endpoint.

• Endpoint: https://mcp.brain-tube.com/mcp (Streamable HTTP)
• Version: 3.12.3
• Auth: OAuth 2.0 (authorization code + PKCE) or a BrainTube API key via X-BrainTube-Token header
• Discovery: /.well-known/oauth-protected-resource · /.well-known/oauth-authorization-server

What it does

Your AI can search and cite your own corpus instead of starting every conversation cold:

• Semantic + keyword search over everything you've saved, with citations back to the source (down to video timestamps)
• Ingest notes, articles and web content directly from any MCP client
• Knowledge graph & related-item traversal across your corpus
• Session context — expertise profile, recent activity, and resurfacing tools
• Per-user isolation — JWT-scoped access; you only ever see your own corpus

Quickstart

1. Create an account at brain-tube.com and get an API key (or use OAuth from a compatible client).
2. Add the server to your MCP client:

{
  "mcpServers": {
    "braintube": {
      "type": "http",
      "url": "https://mcp.brain-tube.com/mcp",
      "headers": { "X-BrainTube-Token": "bt_..." }
    }
  }
}

Works with any MCP-capable client (Claude, Cursor, and others). In clients with OAuth support, just add the endpoint URL and sign in when prompted.
