You dont need a plugin.

"tf_bot_quota" = "0" game - Determines the total number of tf bots in the game. "tf_bot_quota_mode" = "fill" ( def. "normal" ) game - Determines the type of quota. Allowed values: 'normal', 'fill', and 'match'. If 'fill', the server will adjust bots to keep N players in the game, where N is bot_quota. If 'match', the server will maintain a 1:N ratio of humans to bots, where N is bot_quota. "tf_bot_auto_vacate" = "1" game - If nonzero, bots will automatically leave to make room for human players.

So in your server.cfg just add the following lines:

tf_bot_quota "4"
tf_bot_quota_mode "fill"
tf_bot_auto_vacate "1"
