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.
  • Recursively check all the child rooms for the given rooms (spaces) by setting the --recursive flag.
  • Output the results as JSON by setting the --json flag.

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
