Logic Block Tools

Overview

Logic Blocks are the atomic units of business logic in Flowon. The MCP Server supports the full lifecycle of Logic Blocks: listing, reading, creating, updating, and inspecting their dependencies.

The MCP Server supports all five Logic Block types:

Formula	`create_formula_logic_block`	Calculations and value derivations
Decision Table	`create_decision_table_logic_block`	Grid-based rule evaluation
Decision Tree	`create_decision_tree_logic_block`	Hierarchical branching conditions
Validation	`create_validation_logic_block`	Single business rule enforcement
Validation Set	`create_validation_set_logic_block`	Grouped validation rules
