Get your vault online in 5 minutes.

TheBrainfy turns your markdown vault into a live MCP server. Drop .md files, we index them with pgvector, and Claude Desktop queries them like any other tool. Below: the loop, the tools, the pricing, and the obvious questions.

Quickstart

Three steps. ~5 minutes if your Claude Desktop is already installed.

1
Sign up + create a project
Head to /signup (OAuth Google/GitHub or email). Pick a project slug (e.g. acme-notes). The slug becomes your MCP endpoint URL.
2
Upload your .md files
Drag-drop a folder, paste a GitHub repo URL, or sync via rsync. Indexing kicks off automatically — embeddings are generated with text-embedding-3-small (per-note, per-chunk).
3
Connect Claude Desktop
Copy your MCP config snippet from Project → Connect. Paste into claude_desktop_config.json, restart Claude. Ask: "search my vault for ADR-006" — done.

API endpoints

Seven MCP tools exposed per project. Auth via email allowlist + signed JWT. Read-only by default — write tools land in v0.2.

Tool	Description
search_notes	Semantic search across your vault. Returns top-K notes ranked by pgvector cosine similarity.
read_note	Read full markdown of a note by id or path. Returns raw .md + frontmatter parsed.
list_notes	List notes filtered by tag, folder, or updated_at. Paginated.
get_backlinks	Return notes that wikilink to a given note. Bidirectional graph traversal.
list_tags	All tags in the vault with note counts. Useful for triage/overview prompts.
get_recent	Latest N notes by updated_at. Default 10, max 50.
vault_stats	Snapshot of vault size: total notes, total tokens, last index run, top folders.

FAQ

The questions every prospect asks in the first 5 minutes.

What is MCP?: Model Context Protocol — Anthropic's open standard for connecting LLMs to external data/tools. TheBrainfy publishes your vault as an MCP server so Claude Desktop (and other MCP clients) can search and read your notes natively.
What does BYOC (Bring Your Own Claude) mean?: You use your own Anthropic API key from Claude Desktop. We never proxy your prompts — Claude talks directly to your MCP endpoint, authenticated via email allowlist. We don't pay for your inference; you don't pay us for tokens.
How do I cancel?: Cancel anytime in Settings → Billing. Your vault stays read-only for 30 days, then archived. No questions, no retention call.
Is it multi-LLM or Claude-only?: Multi-LLM by design. The MCP server is the surface — Claude Desktop, Continue.dev, Cursor, and any MCP-compatible client can consume it. We also expose a REST fallback for GPT/Gemini agents until those vendors ship MCP support natively.
Where is my data stored?: Postgres + pgvector for embeddings/metadata, Cloudflare R2 for raw .md files. EU + US regions available on Pro tier and above. Markdown stays markdown — no proprietary format lock-in. Export full vault as a .zip anytime.
