Enhance Automation Script MCP Tools with Required and Default Input Definitions

Automation Script MCP tools currently derive their input schema from input variables with a LITERAL binding. However, default binding values are not exposed as MCP schema defaults, and variables cannot be marked as required.

As a result, AI assistants and agents cannot accurately determine which inputs are mandatory and which have valid default values. This often requires additional validation logic within the automation script and can lead to unnecessary clarification questions, failed tool calls, and additional token consumption.

My proposal idea is to allow Automation Script variables to define MCP schema attributes such as Required / Option flag, default value (using the variable binding value), and description or usage hint using the input description field.

This would generate a more accurate MCP tool contract, helping AI assistants understand how to invoke the tool correctly on the first attempt.
