**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:** 3.12.4
- **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:
Tested with Claude; 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.ai** — Customize → Connectors → + Add → Add custom connector, paste the endpoint, sign in. No API key needed.
