Manually initiate Google OAuth authentication flow.
NOTE: This is a legacy OAuth 2.0 tool and is disabled when OAuth 2.1 is enabled.
The authentication system automatically handles credential checks and prompts for
authentication when needed. Only use this tool if:
1. You need to re-authenticate with different credentials
2. You want to proactively authenticate before using other tools
3. The automatic authentication flow failed and you need to retry
In most cases, simply try calling the Googl

Search Gmail Messages — Searches messages in a user's Gmail account based on a query.
Returns both Message IDs and Thread IDs for each found message, along with Gmail web interface links for manual verification.
Supports pagination via page_token parameter.
Get Gmail Message Content — Retrieves the full content (subject, sender, recipients, body) of a specific Gmail message.
Bodies are returned inline and truncated at 20,000 characters. Set full=True to
get the complete, untruncated message instead: it is exported to storage and the
response carries a short-lived download URL (HTTP transport) or file path (stdio
transport) rather than the body, so large messages never stream through the model
context. Stateless deployments without GCS staging have no storage, so there

Get Gmail Messages Content Batch — Retrieves the content of multiple Gmail messages in a single batch request.
Supports up to 25 messages per batch to prevent SSL connection exhaustion.
Get Gmail Attachment Content — Downloads an email attachment and saves it to local disk.
In stdio mode, returns the local file path for direct access.
In HTTP mode, returns a temporary download URL (valid for 1 hour).
May re-fetch message metadata to resolve filename and MIME type.
Send Gmail Message — Sends an email using the user's Gmail account. Supports new emails, replies, and
forwards, with optional attachments. Supports Gmail's "Send As" feature to send
from configured alias addresses.
To forward an existing message, pass forward_message_id. The original subject,
body (quoted with a "Forwarded message" header), and attachments are carried over.
In forward mode, body (if any) is prepended as a note and subject is optional.
Threading, reply, and signature options do not apply when forwar

Operate caios.?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal

Draft Gmail Message — Creates a draft email in the user's Gmail account. Supports new, reply, and forward
drafts with optional attachments. Supports Gmail's "Send As" feature to draft from
configured alias addresses.
To save a forward as a draft for review, pass forward_message_id. The original
subject, body (quoted with a "Forwarded message" header), and attachments are
carried over. In forward mode, body (if any) is prepended as a note, subject is
optional, and threading, reply, and signature options do not apply.
Get Gmail Thread Content — Retrieves the complete content of a Gmail conversation thread, including all messages.
Optionally also returns structured ownership analysis so a caller can
determine who sent the last message and who owes whom a response without
re-parsing the formatted string or making a second tool call.
Get Gmail Threads Content Batch — Retrieves the content of multiple Gmail threads in a single batch request.
Supports up to 25 threads per batch to prevent SSL connection exhaustion.
List Gmail Labels — Lists labels in the user's Gmail account.
List Gmail Filters — Lists all Gmail filters configured in the user's mailbox.
Manage Gmail Filter — Manages Gmail filters: create, delete, update, and apply to existing mail.
- update: Gmail has no filter update API, so the filter is recreated (new
one first, then the old one is deleted) and its ID changes. A passed
criteria or filter_action replaces that whole object; omit one to keep
the old filter's.
- apply: runs a filter's label actions on mail ALREADY in the mailbox
(Gmail filters only act on new mail). Only matching messages change,
not whole conversations as in the web UI. U
Modify Gmail Message Labels — Adds or removes labels from a Gmail message.
To archive an email, remove the INBOX label.
To delete an email, add the TRASH label.
Batch Modify Gmail Message Labels — Adds or removes labels on many Gmail messages, or on every message of whole
conversations via thread_ids.
message_ids are sent in one users.messages.batchModify call (Gmail accepts
up to 1000 ids per call). That endpoint returns no per-message result and
silently ignores ids it does not recognise, so by default the messages are
read back afterwards to report which ids actually changed.
thread_ids are modified one at a time with users.threads.modify, e.g.
archive a conversation with remove_labe
Search Drive Files — Searches for files and folders within a user's Google Drive, including shared drives.
Get Drive File Content — Retrieves the content of a specific Google Drive file by ID, supporting files in shared drives.
• Native Google Docs, Sheets, Slides → exported as text / CSV.
• Office files (.docx, .xlsx, .pptx) → unzipped & parsed with std-lib to
extract readable text.
• PDFs → text extracted with pypdf when possible; scanned/image-only PDFs
fall back to a download hint.
• Images (PNG, JPEG, GIF, WebP) → returned as MCP image content after the
metadata header. SVG → returned as its markup; raster images
Get Drive File Download URL — Downloads a Google Drive file and saves it to local disk.
In stdio mode, returns the local file path for direct access.
In HTTP mode, returns a temporary download URL (valid for 1 hour).
In stateless mode (no file storage), returns the file itself as an embedded
resource, up to WORKSPACE_MCP_STATELESS_INLINE_MAX_BYTES (default 10 MiB,
and never more than WORKSPACE_MCP_MAX_FILE_BYTES when that is set).
For Google native files (Docs, Sheets, Slides), exports to a useful format:
- Google Docs ->
List Drive Items — Lists files/folders or shared drive containers, supporting shared drives.
If `drive_id` is specified, lists items within that shared drive. `folder_id` is then relative to that drive (or use drive_id as folder_id for root).
If `drive_id` is not specified, lists items from user's "My Drive" and accessible shared drives (if `include_items_from_all_drives` is True).
Set `resource_type` to "shared_drives" to list shared drive containers instead of folder contents.
Create Drive Folder — Creates a new folder in Google Drive, supporting creation within shared drives.
Create Drive File — Creates a new file in Google Drive, supporting creation within shared drives.
Accepts direct text content, inline base64 bytes, or a fileUrl to fetch content from.
Where local file access is disabled it can instead return an upload URL for the
caller to PUT file bytes to.
This stores the supplied bytes without converting them to Google Docs, Sheets, or
Slides. Use the matching import_to_google_* tool for Google-native conversion.
Import to Google Doc — Imports a file (Markdown, DOCX, TXT, HTML, RTF, ODT) into Google Docs format with automatic conversion.
Google Drive automatically converts the source file to native Google Docs format,
preserving formatting like headings, lists, bold, italic, etc.
Binary sources may be passed directly as base64_content. On a local server a
file on disk can also be passed by path (preferred for batch operations, so
callers do not need to load full file contents into their context).
Import to Google Slides — Imports a presentation (PPTX, PPT, ODP) into Google Slides format with automatic conversion.
Google Drive automatically converts the source presentation to native Google Slides format,
preserving slides, layouts, text, and images.
Binary sources may be passed directly as base64_content. On a local server a
file on disk can also be passed by path (preferred for batch operations, so
callers do not need to load full file contents into their context).
Import to Google Sheets — Imports a spreadsheet (XLSX, XLS, ODS, CSV, TSV) into Google Sheets format with automatic conversion.
Google Drive automatically converts the source spreadsheet to native Google Sheets format,
preserving rows, columns, sheets, and values.
Binary sources may be passed directly as base64_content. On a local server a
file on disk can also be passed by path (preferred for batch operations, so
callers do not need to load full file contents into their context).
Get Drive File Permissions — Gets detailed metadata about a Google Drive file including sharing permissions,
parent folder IDs, ownership, and lifecycle timestamps.
