Config file locations: Claude Desktop → ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows). Cursor → Settings → MCP → Add Server. Any client that speaks MCP streamable-http works with the same URL + X-BrainTube-Token header.

  1. 1Sign in to BrainTube and create an API key at Settings → API Keys.
  2. 2Paste the config above into your MCP client's config (or add the URL + X-BrainTube-Token header through the client's UI).
  3. 3Replace bt_your_key_here with your real key and restart the client.
  4. 4Try: 'Summarize the last 5 videos I saved about pricing.'

Frequently asked

What is MCP and why does BrainTube use it?
Model Context Protocol is an open standard from Anthropic that lets AI clients read external context through a unified interface. BrainTube ships a native MCP server so any compliant client — Claude Desktop, Cursor, Zed — can query your library without bespoke integrations.
Which AI clients work with BrainTube today?
Claude Desktop and Cursor work out of the box via MCP. ChatGPT connects through our OpenAPI bridge for custom GPTs. Any future MCP-compliant client will work without configuration changes on our end.
Do I need to be on a paid plan to use the MCP server?
No. The MCP server is included on every plan, including Free. Paid plans raise the monthly query and ingest limits.
Where is my API key stored and how do I rotate it?
Keys are created in the BrainTube app under Settings → API Keys. They are shown once at creation, hashed at rest, and can be rotated or revoked at any time. Each key has its own audit log.
Can BrainTube read my private notes or only public videos?
BrainTube reads only what you save into your own library — public YouTube videos, articles you ingest, PDFs you upload. It never crawls third-party accounts on your behalf.
What happens to my data if I disconnect a client?
Disconnecting an MCP client removes its access. Your library, summaries, and highlights remain in BrainTube untouched. You can reconnect or export everything at any time.
