Setup guide
Connect KBrain to your AI assistant
KBrain plugs into Claude and ChatGPT through MCP. You add a single connector - it automatically includes every brain you subscribe to, so you can query expert knowledge without leaving your chat.
Before you start
- A KBrain account. Sign in or create one.
- At least one brain you've subscribed to. Browse the marketplace.
- Your personal connector URL, which you'll find on your Connections page once signed in.
Your connector URL
KBrain exposes a single MCP endpoint. The base URL is:
https://www.kbrain.io/api/mcpSign in and open your Connections page to copy the exact connector URL tied to your account. You only need one connector - it covers every brain you subscribe to.

Good to know
One connector, every brain.You don't set up a connector per brain. The single KBrain connector automatically exposes all the brains you subscribe to.
Discovers what you're missing.When your connected brains don't cover a question, your assistant can search the marketplace for a relevant expert brain and share a one-click subscribe link - so you always know when a better source exists.
Secure by OAuth. When your assistant prompts for authentication, KBrain uses OAuth so your credentials are never pasted into the chat.
Read-only.KBrain's tools only retrieve knowledge - they never modify your account or data.
Current scope. MCP workflows are tested with Claude and ChatGPT. Other MCP-compatible clients may work but are not officially supported yet.
Example queries
Once the connector is on, just ask your assistant naturally - it will reach into the brains you subscribe to and answer with cited, expert knowledge.
- “Using KBrain, what do the latest UNESCO figures say about youth literacy in Sub-Saharan Africa?”
- “Search my connected brains for the out-of-school children rate and cite the source.”
- “Ask KBrain to summarize what my subscribed brain covers on this topic.”
- “Ask KBrain to discover an expert brain for this topic and share the subscribe link.”
