GraphQL — 112 Operations for AI Agents
GraphQL schemas are API contracts clients build against: types, queries, mutations, resolvers' public face. act101 navigates the schema structurally, so agents answer "what can I query?" from the contract itself, precisely.
This page is the canonical reference an AI coding agent uses to refactor, query, and analyze GraphQL code through the act MCP server. 112 operations available: 38 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.
Query

Refactor
| Operation | Description |
|---|---|
extract-fragment |
Extract inline selection set into a named fragment |
extract-query-variables |
Extract hardcoded argument values into variables |
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-client-query-hook |
Generate a client-side query hook (Apollo Client, URQL) |
generate-enum-type |
Generate a new enum type with values |
generate-enum-value |
Generate a new enum value in an enum type |
generate-field-in-type |
Generate a new field in an existing type |
generate-field-resolver-map |
Generate a resolver map object for a type (JavaScript/TypeScript) |
generate-field-type-guard |
Generate a TypeScript type guard for a union/interface type |
generate-fragment |
Generate a fragment definition for common selections |
generate-fragment-types |
Generate TypeScript types from fragments |
generate-input-field |
Generate a new field in an input type |
generate-input-type |
Generate a new input type definition |
generate-mutation-hook |
Generate a client-side mutation hook |
generate-mutation-operation |
Generate a mutation operation skeleton |
generate-object-type |
Generate a new object type definition |
generate-query-operation |
Generate a query operation skeleton for a type |
generate-resolver-stub |
Generate a resolver function stub for a field (language-specific) |
generate-schema-file |
Generate a schema.graphql file with all definitions |
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-fragment-spread |
Inline a named fragment spread into its parent selection |
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)] |
merge-selections |
Merge multiple selection sets on the same type |
move-field |
Move a field from one type to a parent/child type |
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-fragment |
Remove a named fragment that is not used |
remove-unused-variable |
Remove a query variable that is not used |
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-argument |
Rename a field argument across all query invocations |
rename-enum-value |
Rename an enum value across schema and queries |
rename-field |
Rename a field in a GraphQL type across all queries |
rename-fragment |
Rename a named fragment across all usages |
rename-type |
Rename a GraphQL type definition and all references |
rename-variable |
Rename a query variable across all usages |
reorganize-schema-fields |
Reorder fields within a type definition |
split-selection |
Split a large selection set into a fragment |
