aems-agent 0.3.2

AEMS Local Bridge Agent — local filesystem access for exam PDFs

AEMS Local Bridge Agent

As of v0.3.2 (2026-05-11), this package is licensed under AGPL-3.0-or-later (previously MIT). The agent links PyMuPDF in-process via aems-pdf-annotator, and AGPL applies to the combined work. See LICENSE for the full text.

A lightweight companion service that runs on localhost and provides REST API access to the local filesystem, enabling the AEMS hosted app to read/write exam PDFs to a user-chosen folder without ever uploading source PDFs to the server.

What it does

• Runs as a local service on 127.0.0.1:61234 (default).
• Exposes an authenticated REST API the AEMS web app uses to read source PDFs and write annotated PDFs from your local storage folder.
• Optional system-tray icon so it's visible while running.
• Optional offline grading bundle support for fully-local workflows.
• Never sends PDF content out unless the user explicitly attaches a Canvas / offline workflow in the hosted app.

Relicense note (v0.3.2, 2026-05-11): Versions ≤ 0.3.1 were licensed under MIT. From v0.3.2 the agent is AGPL-3.0-or-later because it links PyMuPDF (AGPL-3.0) in-process via aems-pdf-annotator. The MIT licence that previously applied to forks of v0.3.1 and earlier remains in effect for those versions.
