mrvc (max room version checker)

mrvc is a tool for determining how many members support which maximum room version for a given Matrix room.

Its output looks something like this:

Features

• Show member count broken down by maximum room version, Matrix server implementation and version and optionally homeserver name.
• Check multiple rooms at once by setting the --room flag multiple times.

Usage

Get a version of mrvc using either go build, nix or the Containerfile.
Furthermore a Matrix account with its access token is required. One way to obtain the access token is by going into Element -> Settings -> "Help & About" and at the bottom under "Advanced" the access token can be copied.

Then just run:

mrvc --user-id @myuser:myhomeserver.tld --token token --room '#name:homeserver.tld'

Note that each option is also available via an environment variable, which is especially useful for providing the access token to mrvc.

For a list of all the available options run:

mrvc -h
