BrainTube MCP Server

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 lets your AI search it and save to it over one endpoint.

• Endpoint: https://mcp.brain-tube.com/mcp (Streamable HTTP)
• Version: 3.14.11
• 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
• Save from your AI — your AI can save what it finds into BrainTube, add notes and tag items in the same session
• 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_..." }    }  }}

Tested with Claude and ChatGPT; any client that speaks MCP streamable HTTP uses the same endpoint. In clients with OAuth support, just add the endpoint URL and sign in when prompted.

Claude Code — one command:

claude mcp add --transport http --scope user braintube https://mcp.brain-tube.com/mcp   --header "X-BrainTube-Token: bt_..."

Claude.ai — Customize → Connectors → + Add → Add custom connector, paste the endpoint, sign in. No API key needed.

ChatGPT — Settings → Plugins → Add → Add custom MCP server. Paste https://mcp.brain-tube.com/mcp, choose OAuth, tick the risk box, Create, then Connect and sign in to BrainTube. No API key needed. ChatGPT uses the search and fetch tools and cites each answer back to your saved item.

Tool profiles — by default a session gets 12 tools: the everyday search, read and save tools, plus braintube_find_tools and braintube_run_tool, which reach the other read-only tools on demand. To register every tool directly, add ?tools=full to the endpoint (https://mcp.brain-tube.com/mcp?tools=full) or send the header X-BrainTube-Tools: full.
