MV2 is a legacy build for Chromium forks with version below 88 (e.g. older Cent Browser). If your workstations run Google Chrome, Microsoft Edge, or any browser with Chromium >= 88, use the Manifest V3 installation instead.
Audience: Hospital IT and Information Security teams. This guide covers the Manifest V2 build — only for Chromium forks with version < 88.

Extension ID

This is the 32-character identifier derived from the MV2 build’s public signing key. Different from MV3 because each build is signed with its own key.

Prerequisites

  • Workstations run a Chromium fork with version < 88 (e.g. Cent Browser on older Chromium)
  • HTTPS outbound connectivity to cdn.telepatia.ai is allowed (port 443)
  • A policy management platform is available (ManageEngine, Intune, GPO, or equivalent)
To confirm the Chromium version: open cent://version (or equivalent). The Chromium version (not the product version) determines the MV2/MV3 decision.

Blocking other extensions (optional)

Obtaining the CRX

1

Check the manifest

Open https://cdn.telepatia.ai/scribe-extension/update-manifest.json.
2

Download the MV2 CRX

Use the URL from the v2.crx.downloadUrl field.
3

Verify integrity

Compare with v2.crx.sha256.

Deployment via ManageEngine Endpoint Central

1

Navigate to Browsers → Manage → Extension Repository

2

Add Extensions → Add Extensions for Google Chrome → Upload Directly

3

Upload the MV2 CRX file

Confirm the Plugin Identifier matches blohhkgibpajgnknfeokemldajkpnfjg.
4

Apply policy to target hosts/groups

5

Wait for propagation

6

Validate (see below)

Deployment via GPO

1

Open Group Policy Management Console

Edit the GPO targeting the clinical workstations OU.
2

Navigate to Computer Configuration → Administrative Templates → Google Chrome → Extensions → ExtensionSettings

3

Enable and paste the MV2 JSON snippet

4

Link the GPO to the target OU

5

Wait for GPO refresh (~90 min) or gpupdate /force

6

Validate (see below)

The ExtensionSettings policy is respected by most Chromium forks that honor Chrome policy keys, including Cent Browser. For forks with custom policy parsing, validate in pilot first.

Network Requirements

Same requirements as MV3. See the MV3 guide for SSL inspection details.

Auto-Update

Same mechanism as MV3 — the browser checks for updates every ~5 hours. The update_url is the same endpoint; the manifest serves both MV2 and MV3 builds.

Post-Installation Validation

  • Open chrome://extensions (or fork equivalent)
  • Confirm Telepatia Scribe Companion appears
  • Confirm it says Installed by your administrator

Ongoing Operations

Same responsibility model as MV3. See the MV3 guide.

Support

Same channels as MV3. Report unexpected behavior during installation through the agreed Telepatia channels.
