GDScript — 132 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze GDScript code through the act MCP server. 132 operations available: 58 refactor, 18 query, 42 analysis, 14 verification. Each operation is callable from Claude Code, Cursor, Codex, OpenCode, or any MCP-compatible agent host. Click any operation for a stable anchor link suitable for citation.

Refactor

Operation	Description
`add-export-annotation`	add @export annotation
`add-guard-clause`	wrap nested block in guard clause (early return)
`add-onready-annotation`	add @onready annotation
`add-static-type`	add static keyword to function
`add-type-annotation`	add type annotation to variable or parameter
`connect-signal`	add signal_name.connect(callable) call
`convert-const-to-var`	convert const to var
`convert-from-await`	convert from await pattern
`convert-if-to-match`	convert if/elif chain to match
`convert-match-to-if`	convert match statement to if/elif
`convert-to-await`	convert to await signal pattern
`convert-to-typed-array`	convert Array to Array[Type] typed array
`convert-var-to-const`	convert var to const
`extract-constant`	extract literal into constant
`extract-function`	extract code block into new function
`extract-variable`	extract expression into variable
`extract_function`	Extract a code selection into a new function — automatically infers parameters, return types, and inserts the call site. Use instead of manually cutting/pasting code. Works without LSP; LSP improves type inference. Params: file (string), new_name (string), start_line (u32), start_column (u32), end_line (u32), end_column (u32) [, preview (bool), receipt (bool)]
`extract_variable`	Extract an expression into a named variable — inserts the declaration and replaces the expression with the variable name. Works without LSP. Params: file (string), new_name (string), start_line (u32), start_column (u32), end_line (u32), end_column (u32) [, preview (bool)]
`generate-constructor`	generate _init() constructor
`generate-export-variable`	generate @export variable
`generate-input-function`	generate _input(event) function
`generate-method-stub`	generate method stub with pass
`generate-node-reference`	generate @onready node reference
`generate-null-check`	generate null check for node reference before access
`generate-physics-process-function`	generate _physics_process(delta) function
`generate-process-function`	generate _process(delta) function
`generate-ready-function`	generate _ready() lifecycle function
`generate-resource-preload`	generate resource preload constant
`generate-setter-getter-pair`	generate property with set/get blocks
`generate-signal-declaration`	generate signal declaration
`generate-signal-handler`	generate signal handler function
`generate-state-machine`	generate _process with enum-based state machine scaffold
`generate-test-stub`	generate test function stub
`generate-tween`	generate create_tween() and tween_property chain
`inline`	Inline a variable, function, or method — replace every usage with its definition body, then remove the original. The inverse of extract. Works without LSP (single-file); LSP enables cross-file inlining. Params: file (string), symbol (string) [, line (u32), preview (bool), receipt (bool)]
`inline-function`	inline function call with body
`inline-variable`	inline variable and remove declaration
`insert_body`	Replace a function's implementation body with new code. AST-validated — rejects if the result has parse errors, so you can't accidentally break syntax. Use instead of manual text editing for function rewrites. Params: file (string), symbol (string), code (string) [, commit (bool)]
`introduce-constant`	extract literal into constant
`introduce-parameter`	convert local variable to parameter
`introduce-variable`	extract expression into variable
`invert-if-condition`	invert condition and swap branches
`move-to-new-script`	extract class into new .gd file
`move_symbol`	Move a function, class, or type to a different file and automatically update all imports across the codebase. Use instead of manually cut/paste + fixing imports. Works without LSP (single-file); LSP enables cross-file import updates. Params: file (string), symbol (string), destination (string) [, preview (bool), receipt (bool)]
`recipe_run`	Run a codemod recipe: declarative match → transform → optional verify across modeled grammars. Preview lists matches; apply writes with optional E7 receipts and all-or-nothing rollback. Returns a per-site report.
`remove-dead-code`	remove unreachable statements after return
`remove-export-annotation`	remove @export annotation
`remove-onready-annotation`	remove @onready annotation
`remove-static-type`	remove static keyword from function
`remove-type-annotation`	remove type annotation
`remove-unused-variable`	remove variable declaration with no references
`rename`	Rename a symbol and automatically update ALL references across the codebase. Safer and faster than find-and-replace — AST-aware, won't rename strings or comments. Works without LSP (single-file); LSP enables cross-file renames. Params: file (string), old_name (string), new_name (string) [, line (u32), column (u32), preview (bool), receipt (bool)]
`rename-class-name`	rename class_name declaration
`rename-function`	rename function and update call sites
`rename-identifier`	rename identifier across all references
`rename-signal`	rename signal and update connections
`simplify-boolean-expression`	simplify redundant boolean logic
`simplify-string-concatenation`	consolidate string concatenation of adjacent string literals
