Let Me Click And Send

A simple client-side mod for Minecraft that removes the run_command click event restriction introduced in version 1.19.1-rc1. Now, non-command messages can once again be freely sent to chat via the run_command click event.

Version Comparison

If you need a solution that doesn't require installation on player clients, there is a server-side version of the mod that performs the same function.

Usage Example

Execute the following command, then click on the displayed text:

# Minecraft [1.7, 1.21.5)
/tellraw @a {"text":"click me to send \"hi\"","clickEvent":{"action":"run_command","value":"hi"}}

In vanilla Minecraft 1.19.1 ~ 1.21.4, after clicking, you won't be able to say anything because hi is not a valid command (doesn't start with /).

With this mod, after clicking, you will automatically send a hi message to the server chat, which matches the behavior of previous Minecraft versions.

Changes in MC 1.21.5+

Starting from MC version 1.21.5, the behavior of run_command has changed significantly.

The first change concerns command syntax and has minor impact:

# Minecraft [1.21.5, ~)
/tellraw @a {"text":"click me to send \"hi\"","click_event":{"action":"run_command","command":"hi"}}

The second change is more substantial:

• The command value is always considered valid, regardless of whether it starts with / or not
• The client automatically removes the / prefix from the command value and sends the remaining string as a command

It's now impossible to correctly distinguish between "run_command for sending chat messages" and "run_command for sending commands".

As a workaround, LetMeClickAndSendForServer for MC >= 1.21.5 replaces certain command values with the /lmcas command. By default, only command values starting with !! are replaced, which is a common command prefix in the MCDReforged plugin ecosystem.

For customizing the replacement behavior, a configuration file has been added at ./config/letmeclickandsendforserver/config.json:

{
    "sendChatPattern": "!!.*"
}

The sendChatPattern parameter should contain a valid regular expression. All command values that fully match the pattern will be sent as chat messages.

To test with default settings, use:

/tellraw @a {"text":"click me to send \"!!MCDR\"","click_event":{"action":"run_command","command":"!!MCDR"}}

This is an exclusively client-side mod that requires no additional dependencies.
