When to pick Unyly Vault
# 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](https://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) ```bash 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.
