The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
createCreates a spreadsheet by taking the new sheet's name as input
listSheetsLists all the sheets present in the spreadsheet. Accepts spreadsheet id as input argument
renameSheetRenames the provided sheet. Accepts spreadsheet id, old name and new name of the sheet as input arguments
createSheetCreates a new sheet in the spreadsheet provided as an argument. Accepts spreadsheet id and name of the sheet to be created as input arguments
spreadsheetInfoGives info about the spreadsheet. Accepts spreadsheetId as an argument.
listSpreadsheetsReturns a list of all the spreadsheets present within the current context. Returns the spreadsheet data in the form of [{spreadsheetId, spreadsheet name},...]
shareSpreadsheetShares the provided spreadsheet to the recipients provided as an argument. Accepts recipients as an array of objects in the form of {email_address, role}. Also, sends a notification email to the users informing them about the access granted to them.
sheetDataReturns the data present in the specified sheet, in the given range. If the range is not provided, it gives the data of the full sheet. Accepts spreadsheetId, sheet name, range as an argument
updateCellsUpdates the values present in the cells specified in the given range for the provided sheet. Accepts spreadsheetId, sheetname, range and data to be entered, as arguments.
batchUpdateUpdates a range of values using the batchUpdate function of google sheets. The ranges are provided along with the values to be updated, in an array. It accepts spreadsheetId, sheet, and ranges as arguments.
addRowsAdds the specified number of rows to the specified sheet. Accepts spreadsheetId, sheetname, count of rows to be added, startRow as arguments
addColumnsAdds the specified number of columns to the specified sheet. Accepts spreadsheetId, sheetname, count of columns to be added, startColumn as arguments
copySheetCopies the contents of the source sheet to destination sheet. Accepts srcSpreadsheet, srcSheet, dstSpreadsheet, dstSheet as arguments.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
CREDENTIALS_CONFIGService-Account via base64-encodedDRIVE_FOLDER_ID1a2B3c4D5e6F...Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
13/13 tools missing one or more hints — create (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); listSheets (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); renameSheet (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +10 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
12/13 tool handlers declare input schemas (92%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 1/13 tool handlers wrap calls in try/catch (8%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.10.2 (high), @modelcontextprotocol/sdk@1.10.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
