Google Workspace MCP Server

Delete a calendar event.

Get a single calendar event by ID.

Create a new calendar event.

List events from a calendar.

Update an existing calendar event with patch semantics (only supplied fields change).

Query free/busy information for one or more calendars over a time range.

Apply updates to a Google Doc (insert, format, replace, or permanently delete content).

Create a new empty Google Doc.

Get a Google Doc's content and metadata.

Add a comment to a file. Set anchor to bind it to an app-defined region — Drive stores this as an opaque JSON string you define yourself, and does not validate or interpret it. Google Workspace editor apps (Docs/Sheets/Slides) still display comments created this way as unanchored; use the Docs/Sheets/Slides APIs directly if visual anchoring in those editors matters.

Permanently delete a comment. Only the comment's own author can delete it — the API rejects the request otherwise.

Get a single comment on a file.

List comments on a file.

Change the text of an existing comment. This overwrites the comment's content; the previous text is not retained. Only the comment's own author can update it — the API rejects the request otherwise. The resolved state can't be changed here: see drive_replies_create's action field.

Copy a file. Useful for converting formats (e.g. markdown to Google Doc).

Create a new file in Google Drive. Use with bodyParams for metadata and optionally upload a local file.

Permanently delete a file.

Download a file's content from Google Drive. Returns the text content for text files, or a base64-encoded string for binary files. For Google Docs/Sheets/Slides, exports to a readable format (plain text by default).

Export a Google Workspace file (Doc, Sheet, Slide) to a specific format. Returns JSON with export metadata. Use drive_files_download for automatic export with content returned inline.

Get a file's metadata by ID. Shared drive files are supported automatically.

List files in Google Drive. Supports search queries via the 'q' parameter. Shared drive files are included automatically.

Update a file's metadata or content.

Share a file by creating a permission.

Revoke a permission from a file, removing that user's/group's/domain's access. Per the Drive API: concurrent permissions operations on the same file aren't supported, only the last update is applied.

List all permissions on a file. Use to audit sharing state — e.g. a permission with type "anyone" means the file is publicly accessible; there is no separate is-public field. Pass fields (e.g. "permissions(id,type,role,emailAddress,domain)") to identify grantees — the default response omits emailAddress/domain.

Propose transferring ownership of a file between personal/consumer Google accounts (use drive_permissions_transferOwnership instead for a same-organization Workspace transfer, which completes immediately). Google Workspace ownership cannot be transferred to an account outside the organization. This does NOT transfer ownership by itself: it sets role=writer + pendingOwner=true, and the prospective owner must separately accept by setting role=owner + transferOwnership=true on their own permission, under their own credentials. Google sends the recipient a notification email that cannot be disabled; nothing changes for the current owner unless and until they accept. Only individual users can be proposed — not groups, domains, or service accounts (service accounts have no Drive storage quota and the transfer will fail). Ownership transfers are not supported for files in shared drives.

Immediately transfer ownership of a file to another Google Workspace account in the SAME organization. The current owner is downgraded to writer as soon as this call succeeds — there is no separate acceptance step — and Google sends the new owner a notification email that cannot be disabled. Only works for files in "My Drive"; not supported for files in a shared drive, since the organization owns those, not an individual. For a transfer between personal/consumer Google accounts, use drive_permissions_proposeOwnershipTransfer instead, which requires the recipient's separate acceptance and does not transfer ownership immediately. Google Workspace ownership cannot be transferred to an account outside the organization.

Change an existing permission's role on a file (e.g. reader to writer). Can remove capabilities by downgrading a role. Ownership transfers are not supported. Per the Drive API: concurrent permissions operations on the same file aren't supported, only the last update is applied.

Add a reply to a comment, or resolve/reopen it — a comment can only be resolved or reopened by posting a reply with action set. content is required unless action is set; combine both to leave closing/reopening text. Setting action changes the parent comment's resolved field, but resolving is advisory only: the API keeps accepting further replies and doesn't hide anything itself, it's on the client to act on resolved being true (e.g. hide or dim the thread).

Permanently delete a reply. Only the reply's own author can delete it — the API rejects the request otherwise.

Get a single reply to a comment.

List replies to a comment.

Change the text of an existing reply. This overwrites the reply's content; the previous text is not retained. Only the reply's own author can update it — the API rejects the request otherwise. Does not support changing action — use drive_replies_create to resolve/reopen.

Create a Gmail draft. Pass threadId to attach the draft to an existing conversation (it will appear as a reply within that thread). The draft is NOT sent — open Gmail to review and send.

Get a single Gmail message by ID.

List Gmail messages matching a query.

Get a full Gmail thread by ID (all messages in the conversation).

List Gmail threads matching a query.

Modify a Gmail thread: add/remove labels. To archive, remove INBOX. To mark read, remove UNREAD. To star, add STARRED.

Apply updates to a spreadsheet (conditional formatting, cell/border formatting, adding sheets, and more). Can also permanently delete content — e.g. removing a sheet or a conditional formatting rule — with no undo via the API.

Get spreadsheet metadata.

Append values after the last row of a spreadsheet range.

Read values from a spreadsheet range.

Write values to a spreadsheet range.

Apply updates to a presentation (insert/update/delete slides, text, shapes, tables, etc). Delete requests in a batch are permanent — the API has no undo.

Create a new blank presentation.

Get a presentation's slides, layouts, masters, and page elements.

Get a single page (slide, layout, or master) from a presentation.

Get a thumbnail image URL for a page (slide, layout, or master).

Delete a task list. If it contains assigned tasks, the originals (in Docs/Chat Spaces) are also removed.
