Move — 135 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Move code through the act MCP server. 135 operations available: 61 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.

Premium language. Operations on Move require an Elite license or above. See pricing.

Refactor

Operation	Description
`add-abilities-to-struct`	Add ability annotations to a struct (copy, drop, store, key)
`add-abort-guard`	Add an abort guard (assert!) before a function body
`add-assert-not-none`	Add an option::is_some assert before an Option is used
`add-mutable-reference`	Convert a value or immutable reference parameter to a mutable reference
`add-reference-parameter`	Convert a value parameter to an immutable reference parameter
`add-type-annotation`	Add explicit type annotation to a function return type
`add-use-statement`	Add a use import statement to the module
`change-function-signature`	Replace the parameter list of a function
`change-function-visibility`	Change a function's visibility (public/private/entry)
`change-struct-visibility`	Change a struct's visibility (public/private)
`consolidate-imports`	Merge duplicate use prefixes into grouped imports
`convert-if-to-match`	Convert if-else chain to match expression
`convert-let-to-var`	Convert a let binding to a mutable var binding
`convert-loop-to-while`	Convert loop with exit condition to while loop
`convert-numeric-literal-to-const`	Convert a numeric literal to a named constant and replace all uses
`convert-string-literal-to-const`	Convert a byte string literal to a named vector<u8> constant
`convert-var-to-let`	Convert a mutable var binding to an immutable let binding
`convert-while-to-loop`	Convert while loop to loop with exit condition
`extract-constant`	Extract a literal value into a named constant
`extract-function`	Extract lines into a new private function and replace with a call
`extract-module-constant`	Extract a magic literal from an expression into a module-level constant
`extract-repeated-pattern`	Extract a repeated expression into a helper function
`extract-variable`	Extract an expression into a named local 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-access-control-function`	Generate a function with a signer-based access control guard
`generate-capability-struct`	Generate a capability pattern struct for access control
`generate-display-impl`	Generate a display/to_string implementation for a struct
`generate-entry-function`	Generate a public entry function for transaction entry points
`generate-equals-impl`	Generate an equality comparison function for a struct
`generate-error-type`	Generate error code constants for a Move module
`generate-event-emission`	Generate an event struct and emit function for a Move module
`generate-hot-potato-struct`	Generate a hot potato struct (no abilities) for forced-transaction flow
`generate-mock-struct`	Generate a test mock struct for unit testing
`generate-struct-constructor`	Generate a constructor function that initialises all struct fields
`generate-struct-getters`	Generate getter functions for struct fields
`generate-struct-new`	Generate a new() constructor function for a struct
`generate-struct-setters`	Generate setter functions for struct fields
`generate-test-function`	Generate a test function stub in the test module
`generate-test-module`	Generate a #[test_only] test module scaffold
`generate-trait-impl`	Generate a trait/interface implementation stub for a struct
`generate-validation-function`	Generate an input validation function with abort guards
`generate-view-function`	Generate a #[view] annotated read-only function
`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 a function's body at the call site
`inline-variable`	Inline a variable's value at its use sites
`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-named-constant`	Introduce a named constant for a literal value and replace all uses
`introduce-parameter`	Add a new parameter to a function signature
`introduce-type-alias`	Introduce a named struct as a type alias for a Move type
`move-function-to-module`	Move a function to another module in the same 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-unused-import`	Remove an unused use statement from the module
`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-identifier`	Rename any identifier across all references in the file
`simplify-conditional`	Simplify a boolean conditional expression
`sort-imports`	Sort use statements alphabetically
`swap-if-branches`	Swap if/else branches and negate the condition
`unwrap-option`	Unwrap a function's Option<T> return type to T
`wrap-in-option`	Wrap a function's return type in Option<T>
