Notiero in Claude Desktop

Let Claude Desktop save notes you can read on your phone later, and search them when you ask what you decided last week.

Set it up

Create a key

Sign in at notiero.com, open Settings › For your AI, pick Add and read the AI folder so it can look things up, and press Create a key. Copy it, it is shown once. It is free.

Open the config file

In Claude Desktop, open Settings › Developer › Edit Config. Paste this in, or merge the notiero entry into your existing mcpServers:

{
  "mcpServers": {
    "notiero": {
      "command": "npx",
      "args": [
        "-y",
        "notiero-mcp"
      ],
      "env": {
        "NOTIERO_API_KEY": "nti_your_key_here"
      }
    }
  }
}

Try it

Restart Claude Desktop, then say: "Save this to my Notiero: we use Postgres because we need joins." Later ask: "What did we decide about the database? Check my Notiero."

Where the config lives

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Check it works

Quit Claude Desktop fully and open it again. Notiero shows up in the tools menu of a new chat. The tools are write_note, append_to_note, search_notes, read_note and list_notes.

If it does not work

It needs Node.js 18 or newer. Check with node -v in a terminal, and install Node from nodejs.org if it is missing.
Windows: if you see an ENOENT error mentioning ${APPDATA}, add your real AppData path to env, e.g. "APPDATA": "C:\\Users\\you\\AppData\\Roaming".
Claude Desktop runs on macOS and Windows.
"Invalid or revoked key": copy the key again, or create a new one in Settings › For your AI.
"Write-only key" when searching: that key can only add notes. Create one with Add and read the AI folder.
Run npx -y notiero-mcp --version in a terminal to check Node can start it.

Add the Claude skill

The server gives Claude the tools. The skill teaches it good habits: what is worth saving, how to title it, and to search before answering from memory.

Common questions

How do I give Claude Desktop a memory?

Connect it to Notiero, a free notebook. Add the notiero-mcp server to Claude Desktop with your Notiero key. Claude Desktop can then save notes, add to them, and with a reading key search and read them in later sessions.

Can Claude Desktop read all my notes?

No. It can only reach the AI folder in your notebook, and it can only read there if you created a key that may read. Locked notes and notes saved as private are never readable. Nothing can be deleted.

Is Notiero free?

Yes. Notiero and the MCP server are free.
