TSX — 145 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze TSX code through the act MCP server. 145 operations available: 71 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-barrel-export`	Add barrel export for module

`add-readonly`	Add readonly modifier to property or parameter
`add-satisfies`	Add satisfies operator for type validation without widening
`add-type-annotation`	Add type annotation to variable or parameter
`add-type-import`	Convert import to type-only import
`change-signature`	Change function signature
`change-visibility`	Change member visibility
`convert-async`	Convert between async/sync function
`convert-callback-to-promise`	Convert callback pattern to Promise
`convert-class-to-function`	Convert class to function
`convert-commonjs-to-esm`	Convert CommonJS to ES modules
`convert-concat`	Convert array concatenation methods
`convert-const-to-let`	Convert const declaration to let
`convert-const-to-var`	Convert const declaration to var
`convert-enum-to-union`	Convert enum to string/number union type
`convert-esm-to-commonjs`	Convert ES modules to CommonJS
`convert-interface-to-type`	Convert interface to type alias
`convert-namespace-to-module`	Convert namespace to module
`convert-promise-chain-to-async`	Convert Promise chain to async/await
`convert-prototype-to-class`	Convert prototype-based pattern to ES6 class
`convert-require-to-import`	Convert require() to import statement
`convert-template`	Convert string concatenation to template literals
`convert-type-to-interface`	Convert type alias to interface
`convert-union-to-enum`	Convert string/number union to enum
`convert-var-to-block-scope`	Convert var declarations to const/let based on mutation
`convert-var-to-const`	Convert var declaration to const
`convert-var-to-let`	Convert var declaration to let
`extract-constant`	Extract value to named constant
`extract-enum-member`	Extract enum member
`extract-function`	Extract code into a new function
`extract-interface`	Create interface from class
`extract-method`	Extract code into a new method
`extract-type`	Extract inline type to type alias
`extract-variable`	Extract expression to 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)]
`flatten`	Flatten nested structure
`generate-accessors`	Generate getters/setters for fields
`generate-constructor`	Generate constructor from fields
`generate-equals`	Generate equals method
`generate-impl`	Generate interface implementation stubs
`generate-mapped-type`	Generate mapped type transformation
`generate-tests`	Generate unit tests
`generate-to-string`	Generate toString method
`generate-type-guard`	Generate type guard 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`	Inline variable or function
`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-field`	Introduce new field
`introduce-parameter`	Introduce new parameter
`move`	Move symbol to another 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-type-annotation`	Remove type annotation from a declaration
`remove-type-assertion`	Remove unnecessary type assertion
`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`	Rename symbol and all references
`use-destructuring`	Use destructuring for assignments
`use-logical-assignment`	Use logical assignment operators
`use-object-shorthand`	Use object property shorthand
`use-private-fields`	Use private class fields
`use-rest-parameters`	Use rest parameters instead of arguments
`use-spread-operator`	Use spread operator for arrays/objects
`use-template-literals`	Use template literals for string interpolation
`wrap-if`	Wrap in if statement
`wrap-null-check`	Wrap in null check guard
`wrap-try-catch`	Wrap in try-catch block
