Notiero in Gemini CLI

Let Gemini CLI save notes into your Notiero notebook and search them when you come back to a task.

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.

Run one command

gemini mcp add -s user -e NOTIERO_API_KEY=nti_your_key_here notiero npx -y notiero-mcp

Or edit settings.json

In ~/.gemini/settings.json:

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

Try it

Restart Gemini CLI, 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

User: ~/.gemini/settings.json. Project: .gemini/settings.json.

Check it works

Run /mcp inside Gemini CLI. Notiero is listed with five tools. 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 (node -v).
Without -s user the server is added to the current project only.
"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.

Common questions

How do I give Gemini CLI a memory?

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

Can Gemini CLI 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.
