The BrainTube MCP server is a personal knowledge management system that lets you search, explore, and analyze content saved from YouTube, articles, PDFs, podcasts, social media, and more — from any MCP-compatible AI client.
Search & Retrieval
search_knowledge— Full-text semantic + keyword search across your entire corpussearch_by_source— Filter search to a specific source type (YouTube, PDF, Reddit, etc.)search_by_date_range— Search scoped to items saved within a date rangedeep_search— Multi-hop search traversing the knowledge graph to surface hidden connectionsget_video— Fetch full item details including transcript, summary, key takeaways, and taint levellist_recent/list_bookmarks— Browse recent saves or bookmarks (filtered by read/unread)random_resurface— Surface forgotten items via spaced repetition (weighted by least retrieved)most_retrieved— See your most frequently accessed items
Knowledge Graph & Relationships
get_related— Find semantically similar items via vector similarityget_knowledge_graph— Build a graph around an item showing typed connections to othersfind_path— Find the shortest path between two items in the knowledge graphget_edge_history— View the temporal history of connections between two items
Corpus Analytics & Health
get_stats— Total items, source type breakdown, taint distributionknowledge_health— Health check: missing embeddings, orphan items, stale content, contradictionsget_knowledge_index— Topic-level index grouped by subject with salience and source infotag_cooccurrence/entity_cooccurrence— Discover co-occurring tags and named entitiesdetect_gaps— Identify thin topics, stale high-value items, unconnected items, missing concept articlesretrieval_quality— Dashboard of search hit rates, zero-result queries, and relevance signals
Session Context
get_session_brief— One-shot bootstrap combining expertise profile, recent AI conversations, and corpus statsget_recent_conversations— Retrieve recently saved Claude and ChatGPT conversations
Brains (Curated Knowledge Bases)
list_brains— List all Brains you've createdchat_with_brain— Ask questions to a public Brain with multi-turn conversation supportget_concept_articles— Query compiled concept articles filtered by cluster or topic
Integrations
connect_readwise/sync_readwise— Connect and sync highlights from Readwise (incremental or full)search_obsidian— Search your local Obsidian vault via the Obsidian Local REST API plugin
Enables saving YouTube videos to a personal knowledge base with semantic search and citation support, including video timestamps.
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 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-TokenheaderDiscovery:
/.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
Create an account at brain-tube.com and get an API key (or use OAuth from a compatible client).
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.
