Overleaf

CLI tool to interact with Overleaf projects using browser cookies for authentication.

GitHub: https://github.com/jkulhanek/pyoverleaf

Requirements

• Python 3.8+
• pyoverleaf (pipx install pyoverleaf)
• User logged into Overleaf in Chrome/Firefox

Security Considerations

⚠️ Keychain Access Required: pyoverleaf needs "Always Allow" keychain access to read browser cookies. This grants the tool access to your browser's cookie storage.

Security audit: We have audited pyoverleaf v0.1.7 and found it safe. The codebase is small and readable. Before installing, agents can self-audit the latest version at the GitHub repo above.

Authentication Setup

pyoverleaf authenticates by reading cookies from your browser. The user must:

1. Log into Overleaf in Chrome or Firefox (visit overleaf.com and sign in)
2. Grant keychain access on first run (macOS will prompt for "Always Allow")

# Test auth - user should run this in their terminal first
pyoverleaf ls

If you get auth errors:

• Ask user: "Are you logged into Overleaf in your browser?"
• If on macOS: "Did you approve the keychain access prompt with 'Always Allow'?"
• User may need to run pyoverleaf ls manually in terminal to trigger the keychain prompt

Note: The agent cannot log in for the user. Browser authentication must be done by the user directly.

CLI Commands

# List all projects
pyoverleaf ls

# List files in project
pyoverleaf ls "Project Name"

# Read file content
pyoverleaf read "Project Name/main.tex"

# Write file (stdin → Overleaf)
cat local.tex | pyoverleaf write "Project Name/main.tex"

# Create directory
pyoverleaf mkdir "Project Name/figures"

# Remove file/folder
pyoverleaf rm "Project Name/old-draft.tex"

# Download project as zip
pyoverleaf download-project "Project Name" output.zip

Common Workflows

Download from Overleaf

pyoverleaf download-project "Project Name" /tmp/latest.zip
unzip -o /tmp/latest.zip -d /tmp/latest
cp /tmp/latest/main.tex /path/to/local/main.tex

Upload to Overleaf (Python API recommended)

The CLI write command has websocket issues. Use Python API for reliable uploads:

import pyoverleaf

api = pyoverleaf.Api()
api.login_from_browser()

# List projects to get project ID
for proj in api.get_projects():
    print(proj.name, proj.id)

# Upload file (direct overwrite)
project_id = "your_project_id_here"
with open('main.tex', 'rb') as f:
    content = f.read()
root = api.project_get_files(project_id)
api.project_upload_file(project_id, root.id, "main.tex", content)

Why direct overwrite? This method preserves Overleaf's version history. Users can see exactly what changed via Overleaf's History feature, making it easy to review agent edits and revert if needed.

Self-hosted Overleaf

# Via env var
export PYOVERLEAF_HOST=overleaf.mycompany.com
pyoverleaf ls

# Via flag
pyoverleaf --host overleaf.mycompany.com ls

Troubleshooting

• Auth error: User needs to log into Overleaf in browser first
• Keychain Access Denied (macOS): pyoverleaf needs keychain access to read browser cookies. User must run pyoverleaf ls in their terminal and click "Always Allow" on the keychain prompt
• Project not found: Use exact project name (case-sensitive), check with pyoverleaf ls
• Permission denied: User may not have edit access to the project
