🚀 v3.1.0 - Operation-Based Progressive Disclosure Architecture #27
Conversation
…tions Previously, the sheets read and update operations ignored sheetId and sheetName parameters, causing operations to always target the default sheet regardless of user input. Changes: - Add sheetId parameter to SheetsReadSchema and SheetsUpdateSchema - Implement resolveRangeWithSheet() helper to resolve sheet identifiers - Add resolveSheetMetadata() and fetchSheetTitleById() helper functions - Automatically prefix ranges with resolved sheet names (e.g., "Sheet1!A1:B10") - Add debug logging for troubleshooting sheet resolution The fix ensures both sheetId and sheetName parameters correctly target the intended sheet across all operations. Fixes the bug where read/update operations would default to an arbitrary sheet instead of respecting user-specified sheet identifiers. 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
Implement operation-based module system following MCP 2025 best practices: - Create src/modules/ structure with drive, sheets, docs, forms modules - Each module exports focused operations (search, read, create, update) - Add comprehensive module types in src/modules/types.ts - Add listTools utility for tool registration This restructuring follows the how2mcp reference architecture and sets foundation for progressive disclosure implementation.
Complete implementation of MCP 2025 progressive disclosure pattern: - Replace executeCode with direct operation-based tool interface - Consolidate 40+ tools into 4 domains: drive, sheets, forms, docs - Each tool takes 'operation' enum + 'params' for dynamic dispatch - Remove isolated-vm dependency and sandbox infrastructure - Update version to 3.1.0 reflecting architectural shift - Update progressive disclosure spec with approval and test markers This reduces initial token overhead from 2,500 to ~200 tokens while maintaining full API access through operation-based interface. Breaking Change: Removes executeCode tool, replaces with direct operation calls following how2mcp reference architecture.
WalkthroughThe pull request implements a major architectural shift from v2.x to v3.1.0, migrating from operation-based tools to a code-execution model. Changes include new modular APIs (Drive, Sheets, Forms, Docs), a sandboxed code execution environment, progressive tool discovery, updated server routing, Docker base image upgrade, and comprehensive documentation for the migration path.

351-365: Remove outdated implementation steps.Lines 351-365 reference removing code execution components and deleting
src/execution/andsrc/tools/executeCode.ts. The note on line 358 says "This has been completed by the user."If these steps are already completed, this section should be removed or moved to a "Completed Steps" section to avoid confusion.
-### Step 2: Remove Code Execution Components (5 minutes) //NOTE: This has been completed by the user. - -**Delete these files:** -```bash -rm -rf src/execution/ -rm src/tools/executeCode.ts -``` - -**Keep these files:** -- ✅ `src/modules/` (all operation modules) -- ✅ `src/tools/listTools.ts` (gdrive://tools resource) - +### Step 2: Code Execution Components Removed ✅ + +The following files have been removed: +- `src/execution/` directory +- `src/tools/executeCode.ts` +src/modules/sheets/update.ts (1)
56-60: Consider extracting range resolution logic.The range resolution logic (prefixing
sheetName!when needed) is duplicated betweenupdateCellsandupdateFormula. Consider extracting this into a helper function to reduce duplication.Apply this pattern:
function resolveRange(range: string, sheetName?: string): string { if (sheetName && !range.includes('!')) { return `${sheetName}!${range}`; } return range; }Then use it in both functions:
const resolvedRange = resolveRange(range, sheetName);Also applies to: 138-142
src/modules/sheets/manage.ts (3)
110-116: Consider safer property assignment pattern.While the non-null assertions are technically safe here (since
gridPropertiesis initialized at line 87), they could be avoided by restructuring the initialization to build the complete object upfront or by using optional chaining with a fallback.Apply this diff for a cleaner approach:
if (frozenRowCount !== undefined) { - sheetProperties.gridProperties!.frozenRowCount = frozenRowCount; + sheetProperties.gridProperties = { + ...sheetProperties.gridProperties, + frozenRowCount, + }; } if (frozenColumnCount !== undefined) { - sheetProperties.gridProperties!.frozenColumnCount = frozenColumnCount; + sheetProperties.gridProperties = { + ...sheetProperties.gridProperties, + frozenColumnCount, + }; }
264-269: Simplify redundant conditional.The pattern
sheetName || undefinedis redundant sincesheetNameis already typed asstring | undefined. This also converts empty strings toundefined, which may not be intended.Apply this diff:
return { sheetId: resolvedSheetId, - oldName: sheetName || undefined, + oldName: sheetName, newName, message: `Successfully renamed sheet to "${newName}"`, };
360-365: Simplify redundant conditional.The pattern
resolvedTitle || undefinedis redundant sinceresolvedTitleis already typed asstring | undefined.Apply this diff:
return { sheetId: resolvedSheetId, - title: resolvedTitle || undefined, + title: resolvedTitle, message: `Successfully deleted sheet "${resolvedTitle || resolvedSheetId}"`, };

51-54: Verify cache deserialization type safety.The cached value is cast to
ReadResultwithout validation. If the cache contains corrupted or stale data with a different shape, this could cause runtime errors downstream.Consider adding runtime validation or using a type guard:
const cached = await context.cacheManager.get(cacheKey); if (cached) { // Validate cached structure if (typeof cached === 'object' && cached !== null && 'fileId' in cached && 'name' in cached && 'mimeType' in cached && 'content' in cached) { context.performanceMonitor.track('drive:read', Date.now() - context.startTime); return cached as ReadResult; } // Invalid cache entry, continue to fetch }src/modules/docs/index.ts (1)
1-74: LGTM! Clean module organization.The docs module barrel export is well-structured with:
- Clear grouping by operation type (create, text, style, table)
- Comprehensive example demonstrating the API
- Proper type exports alongside runtime exports
src/modules/forms/create.ts (1)
42-90: LGTM! Well-structured form creation implementation.The implementation includes:
- Proper type safety with TypeScript interfaces
- Conditional description update using batchUpdate
- Error handling for missing formId
- Performance tracking and logging
- Clear return value with both edit and response URLs
specs/progressive-disclosure.md (1)
1-46: LGTM! Specification aligns with PR objectives.This specification correctly documents the progressive disclosure implementation:
- Reduces token usage from ~2,500 to ~200
- Implements operation-based tools (drive, sheets, forms, docs)
- Removes code execution architecture
This spec is consistent with the PR summary, unlike the README.md and MIGRATION.md which document the opposite direction.

98-106: Breaking change header claims v3.0.0 but package.json shows v3.1.0.Line 78 states "Breaking Changes in v3.0.0" but
package.jsonshows version3.1.0. The version references are inconsistent.Update to match the actual version:
-## 🚨 Breaking Changes in v3.0.0 +## 🚨 Breaking Changes in v3.1.0Or clarify if this is documenting a previous breaking change that remains in v3.1.0.
Likely an incorrect or invalid review comment.
src/modules/docs/create.ts (1)
49-95: Nice end-to-end doc creation flow.Create → optional batchUpdate → optional move is tidy and the telemetry hooks are a great touch.
src/modules/drive/index.ts (1)
25-75: Drive barrel looks great.Grouping the re-exports by operation family keeps the public surface easy to scan.
src/modules/drive/create.ts (1)
45-163: Solid create operations.Metadata construction, uploads, cache invalidation, and logging are all handled cleanly.
src/modules/docs/style.ts (1)
110-182: LGTM! Clean implementation of text styling.The function correctly builds the
textStyleobject conditionally, handles optional properties appropriately, and constructs thefieldsparameter for the batchUpdate API. The RGB color specification (values 0-1) aligns with the Google Docs API requirements.src/modules/docs/text.ts (2)
52-79: LGTM! Straightforward text insertion implementation.The function correctly defaults to index 1 (document start), uses batchUpdate appropriately, and includes proper logging and performance tracking.
133-163: LGTM! Text replacement implementation is sound.The function correctly uses
replaceAllTextwith case-insensitive matching by default, which is a sensible choice for most use cases.src/modules/drive/batch.ts (1)
143-278: LGTM! Robust batch operations implementation.The sequential processing with per-operation error handling is appropriate, allowing partial success and detailed error reporting. The move operation correctly handles parent updates using the Drive API's
addParents/removeParentspattern. Cache invalidation ensures consistency across searches and resource queries.src/modules/sheets/update.ts (1)
144-153: Verify formula application behavior across range.The implementation sends
[[formula]](single cell) to a potentially multi-cell range. According to the docs (lines 114-115), the formula should be "adjusted for each cell (relative references)", but sending a single-cell array may only update the first cell.Please verify this behavior with the Google Sheets API. You may need to either:
- Confirm the API automatically expands the formula across the range, or
- Generate a 2D array matching the range dimensions, each containing the formula
Test with a range like
D2:D10to ensure all 9 cells receive the formula.src/modules/drive/search.ts (1)

Critical: Migration guide documents wrong architecture version.
This migration guide documents a transition TO code execution (executeCode tool) in v3.0.0, but the PR summary states this PR removes the executeCode tool and implements operation-based progressive disclosure in v3.1.0.
The guide's content contradicts the actual changes in this PR:
- Guide shows: v2.x (operation-based) → v3.0 (code execution with
executeCode) - PR changes: v3.0 (code execution) → v3.1.0 (operation-based with 4 domain tools)
This migration guide needs to be completely rewritten to document the v3.0 → v3.1.0 migration (removing code execution, adding operation-based tools), or removed if it's meant to document an older migration. Based on specs/progressive-disclosure.md, the correct migration should show:
Old (v3.0):
{
"name": "executeCode",
"args": {
"code": "import { search } from './modules/drive';\nawait search({...});"
}
}New (v3.1.0):

"args": {
"operation": "search",
"params": {...}

Verify version bump semantics for breaking changes.
The version is bumped to 3.1.0 (minor), but the PR introduces breaking changes (removes executeCode tool). According to semantic versioning, breaking changes should increment the major version.
Consider bumping to 4.0.0 instead:
- "version": "3.1.0",
+ "version": "4.0.0",If keeping 3.1.0, document why the breaking change doesn't warrant a major version bump.

Critical: isolated-vm dependency contradicts PR objectives.
The PR summary explicitly states: "Removes isolated-vm and sandbox execution infrastructure" and "Breaking change: removes executeCode tool."
However, this package.json adds isolated-vm: ^6.0.2 as a new dependency. This directly contradicts the stated PR objectives.
Additionally, specs/progressive-disclosure.md lines 399-417 explicitly documents removing isolated-vm from dependencies and the Dockerfile.
If code execution is being removed in favor of operation-based tools, this dependency should not be added:

| ## 🚨 Breaking Changes in v3.0.0 | ||
|
|
||
| **Major Version Update:** Google Drive MCP Server v2.0.0 introduces significant architectural improvements that require migration from previous versions. | ||
| **Major Version Update:** Google Drive MCP Server v3.0.0 introduces a **code execution architecture** - a fundamental transformation from calling tools to writing JavaScript code. | ||
|
|
||
| ### What Changed? | ||
|
|
||
| We've consolidated **41+ individual tools** into **5 operation-based tools**, following the 2025 MCP architecture patterns from [HOW2MCP](https://github.com/modelcontextprotocol/servers). | ||
| We've replaced **all operation-based tools** with a **single code execution tool**, following Anthropic's MCP engineering best practices for token efficiency and scalability. | ||
|
|
||
| **Before (v1.x):** Each operation was a separate tool | ||
| **Before (v2.x):** Operation-based tool calls | ||
| ```json | ||
| { | ||
| "name": "listSheets", | ||
| "args": { "spreadsheetId": "abc123" } | ||
| "name": "sheets", | ||
| "args": { | ||
| "operation": "read", | ||
| "spreadsheetId": "abc123", | ||
| "range": "Sheet1!A1:B10" | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| **After (v2.0.0):** Operations are parameters within consolidated tools | ||
| **After (v3.0.0):** Write JavaScript code | ||
| ```json | ||
| { | ||
| "name": "sheets", | ||
| "name": "executeCode", | ||
| "args": { | ||
| "operation": "list", | ||
| "spreadsheetId": "abc123" | ||
| "code": "import { readSheet } from './modules/sheets';\nconst data = await readSheet({ spreadsheetId: 'abc123', range: 'Sheet1!A1:B10' });\nreturn data;" | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| ### Why This Improves Your Experience | ||
|
|
||
| - **88% Reduction in Tool Count** (41+ → 5) - LLMs can select the right tool faster | ||
| - **Better Type Safety** - Zod discriminated unions for reliable operation routing | ||
| - **Cleaner API** - Logical grouping by service (sheets, drive, forms, docs, batch) | ||
| - **Future-Proof** - Follows 2025 MCP architecture best practices | ||
| - **98.7% Token Reduction** - Progressive discovery means only load operations you use | ||
| - **Local Data Processing** - Filter/transform data before returning to model (90-95% data reduction) | ||
| - **Complex Workflows** - Write loops, conditionals, multi-step logic in single execution | ||
| - **Unlimited Scalability** - Foundation for hundreds of operations without context bloat | ||

|
|
||
| --- | ||
|
|
||
| ## 💻 Code Execution Architecture (v3.0) | ||
|
|
||
| ### Overview | ||
|
|
||
| Instead of calling individual tools, you write JavaScript code that imports and uses Google Workspace operations directly. This provides massive token efficiency and enables complex workflows. | ||
|
|
||
| ### Quick Example | ||
|
|
||
| **Search and filter files locally:** | ||
| ```javascript | ||
| import { search } from './modules/drive'; | ||
|
|
||
| // Search once | ||
| const results = await search({ query: 'reports 2025' }); | ||
|
|
||
| // Filter locally (no tokens consumed) | ||
| const q1Reports = results.files | ||
| .filter(f => f.name.includes('Q1')) | ||
| .slice(0, 5); | ||
|
|
||
| // Return only what's needed | ||
| return { | ||
| count: q1Reports.length, | ||
| files: q1Reports.map(f => ({ name: f.name, id: f.id })) | ||
| }; | ||
| ``` | ||
|
|
||
| ### Available Modules | ||
|
|
||
| #### `./modules/drive` - File Operations | ||
| - `search(options)` - Search for files/folders | ||
| - `enhancedSearch(options)` - Search with natural language parsing | ||
| - `read(options)` - Read file content | ||
| - `createFile(options)` - Create new file | ||
| - `updateFile(options)` - Update existing file | ||
| - `createFolder(options)` - Create new folder | ||
| - `batchOperations(options)` - Batch create/update/delete/move | ||
|
|
||
| #### `./modules/sheets` - Spreadsheet Operations | ||
| - `listSheets(options)` - List all sheets in spreadsheet | ||
| - `readSheet(options)` - Read spreadsheet data | ||
| - `createSheet(options)` - Create new sheet | ||
| - `renameSheet(options)` - Rename sheet | ||
| - `deleteSheet(options)` - Delete sheet | ||
| - `updateCells(options)` - Update cell values | ||
| - `updateCellsWithFormula(options)` - Update with formulas | ||
| - `formatCells(options)` - Apply formatting | ||
| - `addConditionalFormatting(options)` - Add conditional rules | ||
| - `freezeRowsColumns(options)` - Freeze rows/columns | ||
| - `setColumnWidth(options)` - Set column widths | ||
| - `appendRows(options)` - Append rows | ||
|
|
||
| #### `./modules/forms` - Form Operations | ||
| - `createForm(options)` - Create new form | ||
| - `readForm(options)` - Read form details | ||
| - `addQuestion(options)` - Add question to form | ||
| - `listResponses(options)` - List form responses | ||
|
|
||
| #### `./modules/docs` - Document Operations | ||
| - `createDocument(options)` - Create new document | ||
| - `insertText(options)` - Insert text at position | ||
| - `replaceText(options)` - Replace text | ||
| - `applyTextStyle(options)` - Apply text formatting | ||
| - `insertTable(options)` - Insert table | ||
|
|
||
| ### Progressive Tool Discovery | ||
|
|
||
| Use the `gdrive://tools` resource to discover available operations on-demand: | ||
|
|
||
| ``` | ||
| Resource: gdrive://tools | ||
| Returns: Complete hierarchical structure of all modules and functions | ||
| ``` | ||
|
|
||
| This enables **progressive discovery** - agents only load documentation for operations they actually use. | ||
|
|
||
| ### Example Workflows | ||
|
|
||
| **Create and populate a spreadsheet:** | ||
| ```javascript | ||
| import { createFile } from './modules/drive'; | ||
| import { updateCells, formatCells } from './modules/sheets'; | ||
|
|
||
| // Create spreadsheet | ||
| const sheet = await createFile({ | ||
| name: 'Q1 Sales Report', | ||
| mimeType: 'application/vnd.google-apps.spreadsheet' | ||
| }); | ||
|
|
||
| // Add data | ||
| await updateCells({ | ||
| spreadsheetId: sheet.id, | ||
| range: 'Sheet1!A1:C2', | ||
| values: [ | ||
| ['Product', 'Revenue', 'Status'], | ||
| ['Widget A', 50000, 'Active'] | ||
| ] | ||
| }); | ||
|
|
||
| // Format header | ||
| await formatCells({ | ||
| spreadsheetId: sheet.id, | ||
| sheetId: 0, | ||
| range: { startRowIndex: 0, endRowIndex: 1 }, | ||
| format: { | ||
| textFormat: { bold: true }, | ||
| backgroundColor: { red: 0.2, green: 0.4, blue: 0.8 } | ||
| } | ||
| }); | ||
|
|
||
| return { spreadsheetId: sheet.id, url: sheet.webViewLink }; | ||
| ``` | ||
|
|
||
| **Batch process documents:** | ||
| ```javascript | ||
| import { search, read } from './modules/drive'; | ||
|
|
||
| const files = await search({ query: 'type:document' }); | ||
| const summaries = []; | ||
|
|
||
| for (const file of files.slice(0, 10)) { | ||
| const content = await read({ fileId: file.id }); | ||
| summaries.push({ | ||
| name: file.name, | ||
| wordCount: content.split(/\s+/).length, | ||
| hasUrgent: content.includes('urgent') | ||
| }); | ||
| } | ||
|
|
||
| return summaries; | ||
| ``` | ||
|
|
||
| ### Security & Limits | ||
|
|
||
| All existing tool calls must be updated to use the new operation-based format. See the migration guide for comprehensive before/after examples covering all 32 operations. | ||
| - **Timeout:** Max 120 seconds (default: 30s) | ||
| - **Memory:** Max 128MB per execution | ||
| - **CPU:** Limited to timeout duration | ||
| - **Isolation:** Sandboxed environment via isolated-vm | ||
| - **Access:** Only Google APIs, no filesystem/network | ||

Non-functional placeholder returns false success.
This function logs a warning and returns a success message without actually formatting cells. This creates a misleading user experience where operations appear to succeed but have no effect.
Consider one of these approaches:
- Remove until ready: Don't export these functions until fully implemented
- Throw not implemented: Explicitly throw an error so callers know it's not ready
- Complete implementation: Implement the actual formatting logic with
batchUpdate

Inconsistent title resolution when using sheetId.
When sheetId is provided without sheetName, the resolvedTitle is set to sheetName (which is likely undefined). This differs from the sheetName branch (lines 321-335) which fetches the title from the API. This creates an inconsistent user experience where the success message shows the numeric ID instead of the sheet name.
Consider fetching the title in both cases for consistency:
if (typeof sheetId === 'number') {
resolvedSheetId = sheetId;
- resolvedTitle = sheetName;
+ // Fetch title for consistent messaging
+ const response = await context.sheets.spreadsheets.get({
+ spreadsheetId,
+ fields: 'sheets(properties(sheetId,title))',
+ });
+ const match = response.data.sheets?.find(s => s.properties?.sheetId === sheetId);
+ resolvedTitle = match?.properties?.title;
} else if (sheetName) {Committable suggestion skipped: line range outside the PR's diff.

In src/modules/sheets/manage.ts around lines 318 to 320, when sheetId is
provided the code sets resolvedTitle = sheetName (likely undefined) causing
inconsistent success messages; change this so both branches resolve the title
the same way: after assigning resolvedSheetId from sheetId, call the same
API/helper used in the sheetName branch to fetch the sheet metadata (title) for
that numeric ID, set resolvedTitle to the fetched title, and preserve the same
error handling/fallback logic used in the sheetName branch so the success
message always displays the actual sheet name.

Honor sheetId when resolving ranges.
ReadSheetOptions.sheetId is ignored, so callers hitting sheets identified only by ID end up querying the wrong tab whenever the range omits the sheet name or the tab is renamed. spreadsheets.values.get expects an A1 range that includes the tab title, so we need to resolve the ID to the title (for example via spreadsheets.get sheet metadata) before building resolvedRange.(developers.google.com)
Apply a fix along these lines:
- const { spreadsheetId, range, sheetName } = options;
- let resolvedRange = range;
- if (sheetName && !range.includes('!')) {
- resolvedRange = `${sheetName}!${range}`;
- }
+ const { spreadsheetId, range, sheetName, sheetId } = options;
+ let resolvedRange = range.trim();
+ if (!resolvedRange.includes('!')) {
+ if (sheetName) {
+ resolvedRange = `${sheetName}!${resolvedRange}`;
+ } else if (typeof sheetId === 'number') {
+ const { data } = await context.sheets.spreadsheets.get({
+ spreadsheetId,
+ fields: 'sheets(properties(sheetId,title))',
+ });
+ const match = data.sheets?.find((sheet) => sheet.properties?.sheetId === sheetId)?.properties?.title;
+ if (!match) {
+ throw new Error(`Sheet ID ${sheetId} not found in spreadsheet ${spreadsheetId}`);
+ }
+ resolvedRange = `${match}!${resolvedRange}`;
+ }
+ }This keeps the documented sheetId flow working even if the sheet gets renamed.

Fix gdrive://tools metadata to match the new operations
Line [68] onward still advertises the legacy Graph-style context.drive.files.* endpoints (and even says Forms/Docs are unavailable), but the server now exposes high-level operations like "search", "createFolder", "listSheets", "createDocument", etc. That means an agent reading gdrive://tools gets instructions for operations it cannot call, while the real operations remain undocumented. Following the published flow will produce Unknown … operation errors, breaking progressive discovery entirely. Please update generateToolStructure() (and the downstream helpers) so it lists the actual v3.1.0 operations and signatures—e.g. search({ query, pageSize }, context), listSheets({ spreadsheetId }, context), insertTable({ documentId, rows, columns }, context), and so on—for every tool. Otherwise the discovery resource is lying about the surface area we just shipped.
