Cairo — 120 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Cairo code through the act MCP server. 120 operations available: 46 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 Cairo require an Elite license or above. See pricing.

Refactor

Operation	Description
`add-missing-match-arm`	Add a missing match arm for a variant
`add-mut-keyword`	Add the mut keyword to a variable declaration
`add-return-statement`	Add a return statement to a function
`add-trait-bounds`	Add trait bounds to a generic type parameter
`add-type-annotation`	Add explicit type annotation to a variable binding
`consolidate-imports`	Merge multiple use statements from the same module into one
`consolidate-match-arms`	Merge match arms with identical bodies
`convert-loop-to-while`	Convert a loop block to a while loop
`convert-match-to-if`	Convert a simple match to an if-else expression
`extract-constant`	Extract a value into a named constant
`extract-function`	Extract a block of Cairo code into a new function
`extract-variable`	Extract an expression into a named 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-cairo-contract`	Generate a Starknet contract skeleton
`generate-cairo-interface`	Generate a Starknet contract interface
`generate-cairo-test-module`	Generate a tests module with #[cfg(test)] attribute
`generate-debug-impl`	Generate a Display/Debug implementation for a struct
`generate-docstring`	Generate a doc comment template above a function or struct
`generate-error-type`	Generate a custom error enum with variants
`generate-function-stub`	Generate a function signature with empty body
`generate-getter-setter`	Generate getter and setter methods for a struct field
`generate-impl-block`	Generate an empty impl block for a struct
`generate-match-arms`	Generate match arms for all enum variants
`generate-partial-eq-impl`	Generate a PartialEq implementation for a struct
`generate-struct-constructor`	Generate a constructor function for a struct
`generate-test-function`	Generate a test function with #[test] attribute
`generate-trait-impl`	Generate a trait implementation stub for a struct
`generate-use-statement`	Insert a use statement at the top of the file
`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-constant`	Replace a constant reference with its literal value
`inline-variable`	Replace a variable with its assigned value
`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)]
`invert-if-expression`	Invert an if expression by negating the condition
`merge-if-statements`	Merge consecutive if statements with the same condition
`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)]
`organize-imports`	Sort use statements alphabetically
`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-mut-keyword`	Remove the mut keyword from a variable declaration
`remove-return-statement`	Remove an explicit return statement from a function
`remove-unused-import`	Remove an unused use statement from a Cairo file
`remove-unused-variable`	Remove an unused variable declaration
`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 occurrences in a Cairo file
`simplify-arithmetic-expression`	Simplify trivial felt252 arithmetic (x + 0, x * 1, etc.)
`simplify-if-expression`	Simplify an if expression in a Cairo file
