mindin

mindin

Memory for Claude and coding agents, kept as markdown notes you own, with a schema that holds and a tie to your git history.

Install

curl -fsSL https://mindin.dev/install.sh | sh

It installs the mindin command with uv, asks where your vault lives (a folder, an S3 bucket or a vault server), and offers to add the vault to Claude Code, Codex and Cursor; it changes nothing in them without a yes. mindin was called notes-vault-mcp: the notes-vault-mcp package and command still work, and install and run mindin.

A vault server

A vault server with Docker Compose, for claude.ai, Claude Desktop, mobile and every machine you work on. You need a domain pointing at the machine, ports 80 and 443 open, and an SMTP account for sign-in links.

mkdir notes-vault && cd notes-vault
curl -fsSL -O https://github.com/gronare/mindin/releases/latest/download/compose.yml -O https://github.com/gronare/mindin/releases/latest/download/Caddyfile
curl -fsSL -o .env https://github.com/gronare/mindin/releases/latest/download/example.env
docker compose run --rm --no-deps vault master-key generate   # paste into .env, with VAULT_HOST and SMTP
docker compose up -d
docker compose exec vault mindin accounts invite [email protected]

Then open https://VAULT_HOST/account and sign in. Install with Docker walks through each step.

Without the script, on one machine: uv tool install mindin, then mindin setup.

mindin asks before it shares anonymous usage data, and sends nothing until you say yes: then, once a day, a random install id, mindin's version, the OS and CPU type and how mindin runs (plugin, CLI or server) go to signals.mindin.dev, never notes, names, paths or your vault's address. mindin setup --signals yes|no changes the answer. The install signal has the details.

Use

Add the server's address, https://VAULT_HOST/mcp, as a custom connector in claude.ai. Claude searches, reads and writes your notes. The same search from a shell on a signed-in machine:

$ mindin search "signing in"
1 note · archive and superseded hidden

myapp  system  3 days
Areas/myapp.md
  ## Sign-in Users sign in with passkeys; email links are the fallback.

What you get

• Notes you own. Plain markdown in a folder or an S3 bucket; open them in Obsidian, keep them in git.
• A schema with teeth. Required fields, legal statuses and kinds, a tag vocabulary; a write that breaks the contract is refused. Start from PARA, a simple vault, a journal or your own layout.
• A lifecycle. close archives finished work, backlog_add files what was deferred, log_append writes one line per repo per session, lint reports drift.
• Memory tied to code. A note names the paths it describes; the session-start hook prints the commits newer than the note.
• Search that reads your languages. Stemming, folded diacritics, synonyms, and optional search by meaning that runs on your machine.
• Your own vault server. Accounts with passkeys, email links, GitHub or your identity provider, several vaults each, shared vaults, sealed in storage.
