Unyly Vault MCP

Connect Claude Desktop / Claude Code / Cursor to your personal Unyly Vault — a markdown knowledge base that lives in the cloud, synced to your account at unyly.org/vault.

Once installed, Claude gets the following tools:

• vault_search — full-text search across all your notes
• vault_list — list notes (filter by tag, pinned, favorite, daily)
• vault_get — fetch a single note (incl. backlinks)
• vault_create — create a new markdown note
• vault_update — edit an existing note
• vault_backlinks — find every note that links to a slug

Setup (one command)

curl -fsSL https://unyly.org/install | sh -s -- install unyly-vault

The CLI:

1. Detects the unyly-vault slug → opens browser → you confirm in-page
2. Issues a personal token bound to your account
3. Writes the right config for every MCP-aware IDE on your machine — Claude Desktop, Claude Code, Cursor — with the auth header already filled in

Already have the CLI? Just unyly install unyly-vault.

Why bother

Unlike a local Obsidian vault, your second brain is now available to every Claude session — even on a different machine or via the web app. Notes you write in browser-based Vault are instantly visible to Claude. Notes Claude creates via tools land back in your Vault.

It's a true two-way "second brain" backed by the marketplace where you also discover new MCPs.
