Describe the whole flow and it is built, tested on every scenario and kept running. Gmail **2** triggers Gmail **41** actions Google Calendar **6** triggers Google Calendar **45** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want Gmail and Google Calendar to do together? Give your AI client this address. `https://mcp.apiant.ai` One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser. ### Set it up in your client ### Claude Code Run this in the directory you want to work in. `claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai` Start Claude Code there, approve the server, and sign in in the browser page it opens. [Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code) ### Claude, web and desktop Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Cursor Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Zed Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Codex and the ChatGPT desktop app Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Any other MCP client Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) Gmail and Google Calendar hold the same work in two places: the thread where a meeting gets agreed, and the slot where it actually sits. Connecting them lets an incoming or sent Gmail message create or find the matching Google Calendar event, and lets calendar changes come back as replies, drafts or labels in the mailbox. Example flows ## What Gmail and Google Calendar can do together ### From Gmail to Google Calendar - When **Email Sent** in Gmail then **Create Event** in Google Calendar - When **New Gmail Message** in Gmail then **Update Event** in Google Calendar ### From Google Calendar to Gmail - When **Attendee Response Changed** in Google Calendar then **Create Email Draft** in Gmail - When **Event Starting Soon** in Google Calendar then **Send Email** in Gmail Starting points drawn from the triggers and actions in the catalog today. Describe the flow you need, at any depth, and your agent builds it and tests every scenario before it ships. Everything your agent can do with Gmail and Google Calendar ## Triggers and actions 8 triggers · 86 actions - Trigger **Email Sent** Fires when an email is sent from the mailbox (optionally filtered by query). - Trigger **New Gmail Message** Fires when a new email arrives (optionally filtered by query/labels). - Action **Add Label To Email** Adds and/or removes specified gmail labels for a message; ensure `message id` and all `label ids` are valid (use 'listlabels' for custom label ids). - Action **Batch Delete Messages** Tool to permanently delete multiple Gmail messages in bulk, bypassing Trash with no recovery possible. Use when you need to efficiently remove large numbers of emails (e.g., retention enforcement, mailbox hygiene). Use GMAIL_MOVE_TO_TRASH instead when reversibility may be needed. Always obtain explicit user confirmation and verify a sample of message IDs before executing. High-volume calls may trigger 429 rateLimitExceeded or 403 userRateLimitExceeded errors; apply exponential backoff. - Action **Batch Modify Messages** Modify labels on multiple Gmail messages in one efficient API call. Supports up to 1,000 messages per request for bulk operations like archiving, marking as read/unread, or applying custom labels. High-volume calls may return 429 rateLimitExceeded or 403 userRateLimitExceeded; apply exponential backoff. - Action **Create Email Draft** Creates a gmail email draft, supporting to/cc/bcc, subject, plain/html body (ensure `is html=true` for html), attachments, and threading. - Action **Create Label** Creates a new label with a unique name in the specified user's gmail account. - Action **Delete Draft** Permanently deletes a specific gmail draft using its id; ensure the draft exists and the user has necessary permissions for the given `user id`. - Action **Delete Label** Permanently DELETES a user-created Gmail label from the account (not from a message). WARNING: This action DELETES the label definition itself, removing it from all messages. System labels (INBOX, SENT, UNREAD, etc.) cannot be deleted. To add/remove labels from specific messages, use GMAIL_ADD_LABEL_TO_EMAIL action instead. - Action **Delete Message** Permanently deletes a specific email message by its id from a gmail mailbox; for `user id`, use 'me' for the authenticated user or an email address to which the authenticated user has delegated access. - Action **Delete Thread** Tool to immediately and permanently delete a specified thread and all its messages. This operation cannot be undone. Use threads.trash instead for reversible deletion. - Action **Fetch Emails** Fetches a list of email messages from a gmail account, supporting filtering, pagination, and optional full content retrieval. - Action **Fetch Message By Message Id** Fetches a specific email message by its id, provided the `message id` exists and is accessible to the authenticated `user id`. - Action **Fetch Message By Thread Id** Retrieves messages from a gmail thread using its `thread id`, where the thread must be accessible by the specified `user id`. - Action **Forward Message** Forward an existing Gmail message to specified recipients, preserving original body and attachments. Verify recipients and content before forwarding to avoid unintended exposure. Bulk forwarding may trigger 429/5xx rate limits; keep concurrency to 5–10 and apply backoff. Messages near Gmail's size limits may fail; reconstruct a smaller draft if needed. - Action **Get Attachment** Retrieves a specific attachment by id from a message in a user's gmail mailbox, requiring valid message and attachment ids. - Action **Get Contacts** Fetches contacts (connections) for the authenticated google account, allowing selection of specific data fields and pagination. - Action **Get Draft** Retrieves a single Gmail draft by its ID. Use this to fetch and inspect draft content before sending via GMAIL_SEND_DRAFT. The format parameter controls the level of detail returned. - Action **Get Filter** Tool to retrieve a specific Gmail filter by its ID. Use when you need to inspect the criteria and actions of an existing filter. - Action **Get Label** Gets details for a specified Gmail label. Use this to retrieve label information including name, type, visibility settings, message/thread counts, and color. - Action **Get People** Retrieves either a specific person's details (using `resource name`) or lists 'other contacts' (if `other contacts` is true), with `person fields` specifying the data to return. - Action **Get Profile** Retrieves key gmail profile information (email address, message/thread totals, history id) for a user. - Action **Import Message** Tool to import a message into the user's mailbox with standard email delivery scanning and classification. Use when you need to add an existing email to a Gmail account without sending it through SMTP. This method doesn't perform SPF checks, so it might not work for some spam messages. - Action **Insert Message** Tool to insert a message into the user's mailbox similar to IMAP APPEND. Use when you need to add an email directly to a mailbox bypassing most scanning and classification. This does not send a message. - Action **List Drafts** Retrieves a paginated list of email drafts from a user's gmail account. use verbose=true to get full draft details including subject, body, sender, and timestamp. - Action **List History** Tool to list Gmail mailbox change history since a known startHistoryId. Use for incremental mailbox syncs. Persist the latest historyId as a checkpoint across sessions; without it, incremental sync is unreliable. An empty history list in the response is valid and means no new changes occurred. - Action **List Labels** Retrieves a list of all system and user-created labels for the specified gmail account. - Action **List Smime Info** Lists S/MIME configs for the specified send-as alias. Use when you need to retrieve all S/MIME certificate configurations associated with a specific send-as email address. - Action **List Threads** Retrieves a list of email threads from a gmail account, identified by `user id` (email address or 'me'), supporting filtering and pagination. - Action **Modify Thread Labels** Adds or removes specified existing label ids from a gmail thread, affecting all its messages; ensure the thread id is valid. - Action **Move Thread To Trash** Moves the specified thread to the trash. Any messages that belong to the thread are also moved to the trash. - Action **Move To Trash** Moves an existing, non-deleted email message to the trash for the specified user. - Action **Patch Label** Patches the specified label. - Action **Remove Label** Permanently deletes a specific, existing user-created gmail label by its id for a user; cannot delete system labels. - Action **Reply To Thread** Sends a reply within a specific gmail thread using the original thread's subject, requiring a valid `thread id` and correctly formatted email addresses. supports attachments via the `attachment` parameter with valid `s3key`, `mimetype`, and `name`. - Action **Search People** Searches contacts by matching the query against names, nicknames, emails, phone numbers, and organizations, optionally including 'other contacts'. - Action **Send Draft** Sends the specified, existing draft to the recipients in the to, cc, and bcc headers. - Action **Send Email** Sends an email via gmail api using the authenticated user's google profile display name, requiring `is html=true` if the body contains html and valid `s3key`, `mimetype`, `name` for any attachment. - Action **Settings Send As Get** Tool to retrieve a specific send-as alias configuration for a Gmail user. Use when you need to get details about a send-as email address including display name, signature, SMTP settings, and verification status. Fails with HTTP 404 if the specified address is not a member of the send-as collection. - Action **Untrash Message** Tool to remove a message from trash in Gmail. Use when you need to restore a previously trashed email message. - Action **Untrash Thread** Tool to remove a thread from trash in Gmail. Use when you need to restore a deleted thread and its messages. - Action **Update Draft** Updates (replaces) an existing Gmail draft's content in-place by draft ID. This action replaces the entire draft content with the new message - it does not patch individual fields. All fields are optional; if not provided, you should provide complete draft content to avoid data loss. - Action **Update Label** Tool to update the properties of an existing Gmail label. Use when you need to modify label name, visibility settings, or color. - Trigger **Attendee Response Changed** Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status. - Trigger **Calendar Event Sync** Polling trigger that returns full event data including details, attendees, and metadata. For real-time notifications with basic info, use Calendar Event Changes (webhook). - Trigger **Event Canceled or Deleted** Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp. - Trigger **Event Created** Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info. - Trigger **Event Starting Soon** Triggers when a calendar event is within a configured number of minutes from starting. Returns event details, time remaining, attendees, and join links when available. - Trigger **Event Updated** Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values. - Action **Acl Delete** Deletes an access control rule from a Google Calendar. Use when you need to remove sharing permissions for a user, group, or domain. - Action **Acl Get** Retrieves a specific access control rule for a calendar. Use when you need to check permissions for a specific user, group, or domain. - Action **Acl Insert** Creates an access control rule for a calendar. Use when you need to grant sharing permissions to a user, group, or domain. - Action **Acl List** Retrieves the list of access control rules (ACLs) for a specified calendar, providing the necessary 'rule_id' values required for updating specific ACL rules. - Action **Acl Patch** Updates an existing access control rule for a calendar using patch semantics (partial update). This allows modifying specific fields without affecting other properties. IMPORTANT: The ACL rule must already exist on the calendar. This action cannot create new rules. If you receive a 404 Not Found error, the rule does not exist - use ACL insert to create it first, or use ACL list to verify available rules. Each patch request consumes three quota units. For domain-type ACL rules, if PATCH fails with 500 error, this action will automatically fallback to UPDATE method. - Action **Acl Update** Updates an access control rule for the specified calendar. - Action **Acl Watch** Tool to watch for changes to ACL resources. Use when you need to set up real-time notifications for access control list modifications on a calendar. - Action **Batch Events** Execute up to 1000 event mutations (create/patch/delete) in one Google Calendar HTTP batch request with per-item status/results. Use this to materially reduce round-trips for bulk operations like migrations, cleanup, or large-scale updates. - Action **Calendar List Delete** Tool to remove a calendar from the user's calendar list. Use when you need to unsubscribe from or hide a calendar from the user's list. - Action **Calendar List Get** Retrieves metadata for a SINGLE specific calendar from the user's calendar list by its calendar ID. This action requires a calendarId parameter and returns details about that one calendar only. NOTE: This does NOT list all calendars. To list all calendars in the user's calendar list, use GOOGLECALENDAR_CALENDAR_LIST_LIST instead. - Action **Calendar List Insert** Inserts an existing calendar into the user's calendar list. - Action **Calendar List Patch** Updates an existing calendar on the user's calendar list using patch semantics. This method allows partial updates, modifying only the specified fields. - Action **Calendar List Update** Updates an existing entry on the user\'s calendar list. - Action **Calendar List Watch** Watch for changes to CalendarList resources using push notifications.

Use when you need to discontinue push notifications for a specific channel subscription. - Action **Create Calendar** Creates a new secondary Google Calendar with the specified title and optional settings. Use this action when you need to create a new calendar for organizing events separately from the primary calendar. The authenticated user becomes the owner of the newly created calendar. Optional parameters include description, location, and timezone. - Action **Create Event** Creates an event on a google calendar, needing rfc3339 utc start/end times (end after start) and write access to the calendar. by default, adds the organizer as an attendee unless exclude organizer is set to true. - Action **Delete Event** Deletes a specified event by `event id` from a google calendar (`calendar id`); this action is idempotent and raises a 404 error if the event is not found. - Action **Duplicate Calendar** Creates a new, empty google calendar with the specified title (summary). - Action **Events Get** Retrieves a SINGLE event by its unique event_id (REQUIRED). This action does NOT list or search events - it fetches ONE specific event when you already know its ID. If you want to list events within a time range, search for events, or filter by criteria like time_min/time_max, use GOOGLECALENDAR_EVENTS_LIST instead. - Action **Events Import** Tool to import an event as a private copy to a calendar. Use when you need to add an existing event to a calendar using its iCalUID. Only events with eventType='default' can be imported. - Action **Events Instances** Returns instances of the specified recurring event. - Action **Events List** Returns events on the specified calendar. - Action **Events List All Calendars** Return a unified event list across all calendars in the user's calendar list for a given time range. Use when you need a single view of all events across multiple calendars. An inverted or incorrect time range silently returns empty results rather than an error. An empty `items` list means no events matched the filters—adjust `time_min`, `time_max`, or `q` before concluding no events exist. - Action **Events Move** Moves an event to another calendar, i.e., changes an event's organizer. - Action **Events Watch** Watch for changes to events resources. - Action **Find Event** Finds events in a specified google calendar using text query, time ranges (event start/end, last modification), and event types; ensure `timemin` is not chronologically after `timemax` if both are provided. - Action **Find Free Slots** Finds free/busy time slots in google calendars for specified calendars within a defined time range (defaults to the current day utc if `time min`/`time max` are omitted), enhancing busy intervals with event details; `time min` must precede `time max` if both are provided. - Action **Free Busy Query** Returns free/busy information for a set of calendars. - Action **Get Calendar** Retrieves a specific google calendar, identified by `calendar id`, to which the authenticated user has access. - Action **Get Current Date Time** Gets the current date and time, allowing for a specific timezone offset. - Action **List Acl Rules** Retrieves the list of access control rules (acls) for a specified calendar, providing the necessary 'rule id' values required for updating specific acl rules. - Action **List Calendars** Retrieves calendars from the user's google calendar list, with options for pagination and filtering. - Action **Patch Calendar** Partially updates (patches) an existing google calendar, modifying only the fields provided; `summary` is mandatory and cannot be an empty string, and an empty string for `description` or `location` clears them. - Action **Patch Event** Updates specified fields of an existing event in a google calendar using patch semantics (array fields like `attendees` are fully replaced if provided); ensure the `calendar id` and `event id` are valid and the user has write access to the calendar. - Action **Quick Add** Parses natural language text to quickly create a basic google calendar event with its title, date, and time, suitable for simple scheduling; does not support direct attendee addition or recurring events, and `calendar id` must be valid if not 'primary'. - Action **Remove Attendee** Removes an attendee from a specified event in a google calendar; the calendar and event must exist. - Action **Settings Get** Tool to return a single user setting for the authenticated user. Use when you need to retrieve a specific calendar setting value. - Action **Settings List** Returns all user settings for the authenticated user. - Action **Settings Watch** Watch for changes to settings resources. - Action **Sync Events** Synchronizes google calendar events, performing a full sync if no `sync token` is provided or if a 410 gone error (due to an expired token) necessitates it, otherwise performs an incremental sync for events changed since the `sync token` was issued. - Action **Update Acl Rule** Updates an access control rule for the specified calendar. - Action **Update Event** Updates an existing event by `event id` in a google calendar; this is a full put replacement, so provide all desired fields as unspecified ones may be cleared or reset. ## Each app on its own - [ **Gmail** Gmail is Google’s email service, featuring spam protection, search functions, and seamless integration with...](https://apiant.ai/connections/gmail) - [ **Google Calendar** Google Calendar is a time management tool providing scheduling features, event reminders, and integration...](https://apiant.ai/connections/google-calendar) Reviews ## What our customers say ## More from Gmail - [ **Gmail to HubSpot** HubSpot is your all-in-one stop for all of your marketing software needs.](https://apiant.ai/connect/gmail-to-hubspot) - [ **Gmail to Google Sheets** Google Sheets](https://apiant.ai/connect/gmail-to-google-sheets) - [ **Gmail to QuickBooks Online** QuickBooks Online accounting — manage customers, invoices, bills, payments, vendors, expenses, and more via...](https://apiant.ai/connect/gmail-to-quickbooks-online) - [ **Gmail to Pipedrive** Pipedrive is a sales CRM and pipeline management tool.](https://apiant.ai/connect/gmail-to-pipedrive) - [ **Gmail to Notion** A new tool that blends your everyday work apps into one.

Yes, the Reply To Thread action in Gmail uses the thread the trigger email came from, so the confirmation lands under the original conversation. You can also add a label to that message so the thread is marked as handled. ### ### Can it check whether I am actually free before creating the event? Yes, Google Calendar's Find Free Slots or Free Busy Query can run first, and the Create Event action only follows when a slot comes back. If nothing is free, you can have Gmail draft a reply instead of booking anything. ### ### What can start an automation from Gmail? Any of Gmail's 2 triggers in the catalog, including Email Sent and New Gmail Message. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Google Calendar when something happens in Gmail? Any of Google Calendar's 45 actions, including Create Event, Find Free Slots, Quick Add and Create Calendar. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Google Calendar to Gmail? Yes. When something happens in Google Calendar, your agent can act in Gmail too. This page covers both directions: Google Calendar's triggers and Gmail's actions are listed here as well. ### ### Do I have to build a connector for Gmail or Google Calendar? No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use Gmail and Google Calendar without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
