nestornotes 0.2.0

Open-source command-line client for the NestorNotes knowledge base. Auditable thin wrapper around the hosted MCP server.

nestornotes

Open-source command-line client for NestorNotes — your AI-powered knowledge base.

This CLI is a thin, auditable wrapper that talks to the hosted NestorNotes MCP server over the Model Context Protocol. Every line of code that runs on your machine is in this repository — read it before you install.

Surface	Source	License
CLI client (this repo)	src/nestornotes/cli.py, npm/	MIT (open source)
MCP server (hosted)	Proprietary, runs at https://mcp.nestornotes.com/mcp	Closed source

The CLI is generated from the server's tool registry by fastmcp generate-cli — cli.py is regenerated each release and pushed here via PR. You can verify by reading the file directly: it's plain Python, no obfuscation.

Install

Via PyPI (recommended)

uv tool install nestornotes        # or: pipx install nestornotes
nestornotes --help

Run ephemerally without installing: uvx nestornotes --help.

Upgrade: uv tool upgrade nestornotes (or pipx upgrade nestornotes).

Via npm

npm install -g nestornotes         # requires `uv` on PATH (https://astral.sh/uv)

The npm package is a thin Node.js wrapper that proxies to the matching PyPI wheel via uvx — same Python code, different distribution channel.

Usage

nestornotes call-tool list_collections
nestornotes call-tool semantic_search --query "rust async"
nestornotes call-tool list_articles --collection-id <uuid> --limit 5

By default the CLI talks to https://mcp.nestornotes.com/mcp. Override per-environment:

NESTORNOTES_SERVER_URL=http://localhost:8000/mcp nestornotes call-tool list_collections

OAuth is handled automatically by FastMCP: the first tool call opens a browser for Supabase sign-in; the token is cached locally.

What this CLI does (and doesn't)

• Does: Parse your shell arguments → open an HTTPS connection to the configured MCP server → forward your call → print the JSON response.
• Does not: Execute any business logic locally. Cache anything but OAuth tokens. Send telemetry. Talk to anything other than the configured NESTORNOTES_SERVER_URL.

You can verify all of the above by reading src/nestornotes/cli.py — it imports cyclopts (for argument parsing), fastmcp (for the MCP client), and rich (for output). That's it.

How updates happen

This repo is not hand-edited. When the NestorNotes server adds, changes, or removes a tool, an automated PR appears here with the regenerated cli.py. The PR contains exactly two artifact files (plus version bumps) — src/nestornotes/cli.py and src/nestornotes/SKILL.md — so you can diff each release against the previous one to see what changed.

Each release is tagged vX.Y.Z and triggers PyPI + npm publication via GitHub Actions (release.yml).

Verifying what you install

nestornotes --version
gh release view vX.Y.Z --repo nestornotes/nestornotes-cli
pip download --no-deps nestornotes==X.Y.Z
unzip -l nestornotes-X.Y.Z-py3-none-any.whl

The wheel contains exactly three files: __init__.py, cli.py, SKILL.md. Nothing more.

The CLI is open source. The MCP server it talks to is proprietary — but the interface (every tool name, parameter, and docstring) is fully documented here in cli.py.
