Racket — 129 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Racket code through the act MCP server. 129 operations available: 55 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-require`	Add missing module import
`consolidate-requires`	Merge compatible requires
`convert-cond-to-if`	Convert simple cond to if
`convert-cond-to-match`	Convert cond to match pattern
`convert-cons-to-list-syntax`	Convert nested cons chain to (list ...) syntax
`convert-do-to-for`	Convert do loop to for iteration
`convert-do-to-map`	Convert do loop to map/filter/reduce
`convert-if-to-cond`	Convert nested if to cond expression
`convert-if-to-match`	Convert if to match with pattern
`convert-lambda-to-named-function`	Convert lambda to define with same behavior
`convert-let-star-to-let`	Convert let* to let where independent
`convert-let-to-let-star`	Convert let to let* for sequential bindings
`convert-let-to-letrec`	Convert let to letrec for mutual recursion
`convert-letrec-to-let`	Simplify letrec to let where not recursive
`convert-named-function-to-lambda`	Convert simple function to lambda
`convert-string-concatenation`	Convert string-append to string interpolation
`expose-public-api`	Add binding to provide
`extract-function`	Extract code into named function with parameter inference
`extract-local-binding`	Extract subexpression into a let binding
`extract-variable`	Extract expression into named local binding
`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-default-implementation`	Generate default function implementation
`generate-equality-predicate`	Generate equality predicate for struct
`generate-function-stub`	Generate function definition with parameters and placeholder
`generate-interface-stub`	Generate protocol/interface definition
`generate-match-expression`	Generate a match expression skeleton
`generate-module-header`	Generate #lang racket and module wrapper
`generate-require-statement`	Generate a require statement
`generate-string-representation`	Generate string representation function for struct
`generate-struct-accessors`	Generate getter functions for struct fields
`generate-struct-definition`	Generate a struct definition
`generate-stub-with-types`	Generate function with Typed Racket type annotations
`generate-test-scaffold`	Generate test scaffold with rackunit
`hide-implementation-detail`	Move binding from provide
`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`	Replace function call with inlined body
`inline-variable`	Replace variable with its value at all 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-contract`	Add contract annotation to function
`introduce-parameter`	Add new parameter to function with default handling
`invert-if`	Swap if/else branches and negate condition
`move-definition`	Move function/variable definition to another module
`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-requires`	Sort and group require directives
`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-parameter`	Remove unused parameter from function definition
`remove-unused-require`	Remove unused module import
`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 variable, function, or parameter across all references
`rename-module-binding`	Rename binding in module and update imports
`rename-parameter`	Rename function parameter and update references
`reorder-parameters`	Reorder function parameters
`simplify-if`	Simplify redundant if expression
`simplify-lambda`	Simplify lambda via eta reduction
