Brain Graph

Brain Graph MCP

Beta

One-click install — talk to your knowledge graph from any Claude chat (Claude Desktop or claude.ai web). No API keys, no config files, no domain whitelist. Just OAuth and your Brain Graph credentials.

What you can do from chat

Six tools, available as soon as the connector is added. Claude picks the right one based on your prompt — you don't need to mention tool names. Drop in notes, longer documents, web articles, and YouTube videos; ask questions across everything you've captured.

Search your brain

search_brain

Natural-language questions across every fact, document, and relationship you've captured.

Look up an entity

resolve_entity

Resolve a person, organization, project, or topic to its canonical record in your graph.

Save a quick note

upload_text

Capture a thought, decision, or insight directly from chat — straight into your graph.

Save a longer document

upload_document

Upload transcripts, articles, or structured notes with optional title, date, and metadata.

Save a webpage

upload_url

Drop a URL and your brain ingests the article — fetches the page, extracts the readable body, and indexes it like any other document.

Save a YouTube video

upload_youtube_url

Paste a YouTube URL and your brain ingests the video — pulls the transcript, resolves the speakers, and indexes the content. Each video is processed at most once.

Connect in 3 steps

About 30 seconds, one-time. The same setup works for Claude Desktop and claude.ai web.

  1. 1

    Open Claude → Settings → Connectors

    In Claude Desktop, open Settings from the sidebar. On the web, go to claude.ai/settings/connectors.

  2. 2

    Click "Add custom connector" and paste this URL

    https://mcp.itsbraingraph.ai/mcp

    The /mcp suffix matters — it's the protected MCP transport endpoint and the OAuth resource Claude binds your token to. Click Add; Claude opens the Brain Graph login screen.

  3. 3

    Sign in with your Brain Graph email + password

    Same credentials as itsbraingraph.ai. Claude redirects you back fully connected — the six tools above appear in Claude's tools list immediately.

Open Claude Connectors

Try it in chat

Drop any of these prompts into Claude. Claude picks the right tool automatically — you don't need to mention tool names.

Good to know

Your data is yours alone

Claude gets an OAuth token scoped to YOUR account only — no shared key, no bulk credential. Your tools call your graph and nothing else. Tokens are stored encrypted on your device by Claude Desktop / claude.ai. You can revoke any time from Claude's connector settings, or change your Brain Graph password to invalidate all connector sessions at once.

All connector calls flow over HTTPS. The Brain Graph server verifies the user identity on every request — including a cross-check that the OAuth grant matches the user the JWT claims to authenticate. Mismatches and authentication failures are refused before any data is read or written.

Beta — what to expect

  • v1 ships 6 tools. More coming — running agents, finding patterns, time-window queries.
  • Connection lasts 30 days, then prompts re-auth. Tokens auto-refresh in the background; you won't see hourly interruptions.
  • Custom connector for now (you paste the URL). Public listing in the Claude Connectors Directory is in review.
  • Bug or feature request? Email support@itsbraingraph.ai.

Prefer no-code? Connect with Zapier

The MCP connector is for talking to your brain inside Claude. To pull content in automatically from other apps, use the Zapier integration — ready-made Zaps that auto-ingest Google Drive files, YouTube videos, and Krisp or tl;dv meeting transcripts. You can also build your own automations against the BrainGraph API.
