Turn your YouTube watch history, articles, and web content into a searchable knowledge base accessible from Claude, Cursor, and other AI tools via MCP protocol.
BrainTube ships a native Model Context Protocol (MCP) server, so any MCP-capable AI client can read your transcripts, summaries, and highlights as first-class context.
Model Context Protocol is an open standard from Anthropic that gives AI clients one uniform way to read external context. Instead of every tool building a bespoke integration, a client speaks MCP and the server exposes its data and tools through that shared interface.
BrainTube's MCP server is remote and hosted — there is nothing to install. You point a compliant client at the endpoint, authenticate, and your saved library becomes queryable from inside that client.
- Claude Desktop— Read summaries, search transcripts, and ask Claude to reason over your library.
- Cursor— Pull engineering talks and tutorials into your coding workflow as live context.
- ChatGPT (custom GPTs)— Connect via OpenAPI bridge — query your library from any GPT you build.
- Any MCP client— Native Model Context Protocol means any compliant client works out of the box.
Endpoint:https://mcp.brain-tube.com/mcp
Cursor, Claude Desktop, CLI tools, and other MCP clients:

Endpoint:https://mcp.brain-tube.com/mcp(MCP streamable-http)

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. MCP access is included on every plan, including Free. What differs by tier is the credit allowance: saving items, running searches and asking your brain all spend credits, and higher tiers get more of them. Free starts with 30 credits a month.
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.
