Let Me Click And Send for Server

A simple Minecraft server-side mod, that replaces all non-command run_command content with a custom command, to bypass client-side restrictions since 1.19.1-rc1

If you want a more direct solution, here's a client-side only mod that does the same thing: LetMeClickAndSend

Example

Let's run the following command, and then click the shown text

/tellraw @a {"text":"click me to send \"hi\"","clickEvent":{"action":"run_command","value":"hi"}}

In vanilla 1.19.1+, after clicking, you are not able to say anything since hi is not a valid command (not starts with /)

With this mod, the server will automatically replace the value field in the click event above with /lmcas hi, so the client can send the command without any issue after the click. On command received, the server will broadcast a message with the same format as a player message

Requirements

It's a server-side only mod. It requires 0 extra dependency
