#
# Mjolnir has no more granular access controls other than this, be sure you trust everyone in this room - secure it!
#
# This should be a room alias or room ID - not a matrix.to URL.

# A case-insensitive list of ban reasons to have the bot also automatically redact the user's messages for.
#
# If the bot sees you ban a user with a reason that is an (exact case-insensitive) match to this list,
# it will also remove the user's messages automatically.
#
# Typically this is useful to avoid having to give two commands to the bot.
# Advanced: Use asterisks to have the reason match using "globs"
# (f.e. "spam*testing" would match "spam for testing" as well as "spamtesting").

# See here for more info: https://www.digitalocean.com/community/tools/glob

admin:

  # Note: Mjolnir can also be pinged by display name instead of having to use

# Configuration specific to certain toggle-able protections
protections:
  # Configuration for the wordlist plugin, which can ban users based if they say certain
  # blocked words shortly after joining.
  wordlist:
    # A list of case-insensitive keywords that the WordList protection will watch for from new users.
    #
    # WordList will ban users who use these words when first joining a room, so take caution when selecting them.

# Options for advanced monitoring of the health of the bot.
health:
  # healthz options. These options are best for use in container environments
  # like Kubernetes to detect how healthy the service is. The bot will report
  # that it is unhealthy until it is able to process user requests. Typically
  # this means that it'll flag itself as unhealthy for a number of minutes
  # before saying "Now monitoring rooms" and flagging itself healthy.
  #
  # Health is flagged through HTTP status codes, defined below.
  healthz:
    # Whether the healthz integration should be enabled (default false)
