zotcli 0.2.1

A CLI for browsing, exporting, and adding items to a Zotero library

zotcli (zot)

A command-line interface for your local Zotero library. Default: strictly read-only. Write capabilities are opt-in and route through Zotero's own connector HTTP server — zotero.sqlite is never modified directly.

Library stats on this machine: 3,771 items · 200 collections · 3,201 tags · 6.2 GB storage

---

Installation

# Read-only (default)
pip install zotcli

# Adds the write API client (httpx) — required for any zot add … command
pip install "zotcli[write]"

# Adds Playwright for paywalled-PDF retrieval via browser SSO
pip install "zotcli[browser]"

# Everything
pip install "zotcli[all]"

Verify:

zot --help

The database at ~/Zotero/zotero.sqlite is auto-detected on WSL. Override anytime with --db PATH.

Depending on the operating system the Zotero folder can be in different locations. By default, zotcli looks for the database at ~/Zotero/zotero.sqlite, which works for most setups. For Windows users, the Zotero folder is typically located in C:\Users\<YourUsername>\Zotero. For macOS users, it is usually found in ~/Zotero. If you have a custom setup or want to specify a different path, you can use the --db option to point zotcli to the correct location of your zotero.sqlite file.

Architecture

CLI layer  (cli/)
    ↓  Click commands call query functions
Query layer  (queries/)
    ↓  Batch SQL via sqlite3.Row
Database layer  (db.py)       ← read-only URI: file:zotero.sqlite?mode=ro
    ↓
zotero.sqlite

Write path (opt-in):
CLI layer  (cli/add.py)
    ↓  resolve identifiers via external APIs
Resolver pipeline  (write/resolvers/)
    ↓  CSL-JSON
Connector client  (write/connector_client.py)
    ↓  loopback HTTP
Zotero desktop app  →  zotero.sqlite + storage/

See docs/architecture-write.md for the full write-path design.

---

Global options

These go before the subcommand:

zot [--db PATH] [--library ID] [--format table|json|csv] [--no-color] <command>

Write-related globals (only relevant when write.enabled=true):
zot [--allow-write] [--connector-url URL] [--require-zotero/--no-require-zotero] <command>

Writing to your library

Default: strictly read-only. Write capabilities are opt-in and route through Zotero's own connector HTTP server — zotero.sqlite is never modified directly.

Zotero must be running for any zot add … command to succeed.

Enable write capability

# One-time setup (persists to config)
zot config set write.enabled true

# Check current status
zot config get write.enabled

# Verify Zotero is reachable
zot add status

Quick-start: add items

# Add by DOI / arXiv / PMID / ISBN
zot add doi 10.1109/TPWRS.2023.1234567
zot add arxiv 2401.12345 --collection Preprints
zot add pmid 31452104
zot add isbn 978-0-262-03384-8 --collection Books

# IEEE Xplore or ScienceDirect URL (DOI is extracted automatically — no browser needed)
zot add "https://ieeexplore.ieee.org/document/9876543"
zot add "https://www.sciencedirect.com/science/article/pii/S2352467725000XYZ"

# Free-text citation string
zot add "Zhang, J., Geth, F., Heidari, R., Verbič, G. (2025) Beyond simplifications…"

# Local PDF (Zotero auto-recognises the parent reference)
zot add ~/Downloads/paper.pdf

# Smart auto-detect: zot add figures out the type automatically
zot add "10.1109/TPWRS.2023.1234567"   # detected as DOI
zot add "2401.12345"                    # detected as arXiv
zot add "/home/me/paper.pdf"            # detected as file

Batch add

# papers.txt: one DOI / arXiv / URL / citation per line; # = comment
zot add batch papers.txt --collection "Smart Grid" --tag imported

Import from a bibliography file

# .bib, .ris, or .json (CSL-JSON)
zot add import refs.bib --collection "Imports/2026-05"

Optional: paywalled-PDF retrieval

# Step 1: register for Unpaywall (email only; opt-in)
zot add login --service unpaywall

# Step 2: add with open-access PDF
zot add doi 10.1109/X --with-pdf

# For paywalled content: authenticate via browser SSO (requires zotcli[browser])
zot add login --service ieee           # opens headed Chromium; sign in once
zot add login --service sciencedirect
zot add doi 10.1109/X --with-pdf      # re-uses saved cookies

Architecture summary

All writes go through POST /connector/saveItems (and related endpoints) on Zotero's local HTTP server at 127.0.0.1:23119. Zotero performs every database transaction. zotero.sqlite is never opened in write mode by zotcli.

See docs/architecture-write.md for full details.

Running tests

python3 -m pytest tests/ -q

441 passed in Xs

Tests use an in-memory SQLite fixture seeded with synthetic Zotero data. No real database needed. e2e tests (requiring a live Zotero) are opt-in:

python3 -m pytest tests/e2e -m e2e

---

Configuration

Self-contained config at <zotcli-home>/config.toml. Run zot config path to find the directory.

[database]
path = ""                        # empty = auto-detect zotero.sqlite

[write]
enabled = false                  # opt-in; set true once with: zot config set write.enabled true
connector_url = "http://127.0.0.1:23119"
require_zotero = true

[unpaywall]
enabled = false                  # opt-in; set up with: zot add login --service unpaywall
email = ""

[browser]
headless = false                 # SSO/captcha needs headed browser

Override <zotcli-home> with the ZOTCLI_HOME environment variable.

---

Safety

• Database opened with sqlite3://…?mode=ro — the OS-level read-only URI flag makes direct writes impossible
• WAL journal detection warns if Zotero is currently open (pending writes may not be visible yet)
• Write operations route through Zotero's own connector HTTP server — never via direct SQLite mutation
• Default is read-only; writes require explicit opt-in (zot config set write.enabled true)
• No Zotero API key required
