What you can do from chat
Eleven 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_brainNatural-language questions across every fact, document, and relationship you've captured.
Look up an entity
resolve_entityResolve a person, organization, project, or topic to its canonical record in your graph.
List what you've uploaded
list_documentsBrowse your uploaded documents — filename, upload date, and which brain each landed in — newest first. Filter by a search term to find one by name, or ask "what did I add last week?" and see the whole library.
See images from a document
get_document_imagesPull figures, diagrams, screenshots, or slides from one of your uploaded documents and render them inline in chat. Works on PDFs, DOCX, PPTX, and ingested URLs with body images.
Save a quick note
upload_textCapture a thought, decision, or insight directly from chat — straight into your graph.
Upload a file from chat
upload_to_brainDrop a PDF, Word doc, slides, an image, or an audio file straight into a Claude conversation. The connector opens a secure upload widget, runs the right pipeline, and lands it in your brain. Audio up to ~150 MB, documents up to ~35 MB.
Save a longer document
upload_documentUpload transcripts, articles, or structured notes with optional title, date, and metadata.
Save a webpage
upload_urlDrop 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_urlPaste 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.
Transcribe an audio recording
upload_audio_urlShare a public link to an audio file (voice memo, recording, podcast) and your brain transcribes it (with speaker diarization), then indexes the content like any other document.
List your brains
list_brainsSee your separate brains (Personal, Marketing, Learning, …). One connection spans them all — Claude searches everything by default and only narrows when you name a brain ("search my Marketing brain"). No reconnecting, no switching.
Connect in 3 steps
About 30 seconds, one-time. The same setup works for Claude Desktop and claude.ai web.

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 11 tools (including in-chat file upload, image extraction, browsing your uploaded documents, and multi-brain support). 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.
