messages_search_recent

Category: messages

Substring-search recent messages in a channel.

  • Locate a recently sent message by keyword without iterating manually.
  • Server-wide search → not supported by Discord REST. This tool only fans out the most recent N messages of ONE channel and filters client-side. For deep history, use external indexing.
