Add batch/pagination support to Google Drive list-files and download-file#21429
Merged
Conversation
…file Resolves the request in issue #21206 to process large folders in set batches. list-files (0.3.1 -> 0.4.0): - Add `maxResults` to cap how many files are returned per run. pageSize is aligned to the remaining count so the returned nextPageToken lands exactly after the last kept file — no files are skipped when resuming. - Add `pageToken` input and return `{ files, count, nextPageToken, isComplete }` so a run can resume where a previous run stopped (stateless cursor). - Replace the `additionalProps()`-based `filterType` with a static optional prop. download-file (0.1.27 -> 0.2.0): - Add `fileIds` (string[]) to download multiple files in a single run; keep the single `fileId` for backwards compatibility. A single file returns the original object shape; a batch returns `{ files, count }`. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

version to reflect the breaking return-value change, and update the matching
version in the Google Drive component’s package.json.
- Around line 123-126: Update the maxResults validation in the list-files action
to coerce this.maxResults with Number before checking it. Validate the coerced
value as a positive integer, preserving the existing undefined handling and
ConfigurationError message.
In `@components/google_drive/package.json`:
- Line 3: Update the version in the app package.json from the patch bump 1.12.3
to at least the required minor version 1.13.0, matching the largest component

- list-files 0.4.0 -> 1.0.0: the return value changed from an array to an
object ({ files, count, nextPageToken, isComplete }), a breaking change.
- Coerce `maxResults` with Number() before validating so integer values passed
as strings (e.g. via MCP tool input) are accepted; undefined still means no cap.
- Bump components/google_drive/package.json 1.12.3 -> 1.13.0 to reflect the
feature additions.

Summary
Adds batch / pagination support to the Google Drive list-files and download-file actions so large folders can be processed in set batches, per the request in #21206.
list-files(0.3.1 → 0.4.0)Max Results— caps how many files are returned per run.pageSizeis aligned to the number still needed, so the returnednextPageTokenlands exactly after the last kept file — no files are skipped when resuming (a naive "fetch a full page then trim" approach would drop the remainder).Page Tokeninput + returns{ files, count, nextPageToken, isComplete }— pass the previous run'snextPageTokenback in to continue where it stopped (stateless cursor).additionalProps()-basedfilterTypewith a static optional prop.download-file(0.1.27 → 0.2.0)Files(fileIds, string[]) — download multiple files in a single run. The legacy singleFile(fileId) is retained for backwards compatibility; both are merged and de-duped.{ files, count }. Errors ifDestination File Pathis set with multiple files.Testing
Published both to a private registry and ran targeted MCP evals — 5/5 passed:
list-files: folder listing;Max Resultscap (returned exactly 2, flagged more remain); page-token resume (fetched next page with no overlap).download-file: single-file (backwards compat); batch (one call with 3 file IDs returned all three).Closes #21206
