概览

AI 生成的概览

一个本地 MCP 服务器，让 AI 助手读取、创建、更新、移动和删除 Google 日历事件与日历。

可以做什么
按时间范围、文本和重复规则列出、搜索并获取事件，包括重复事件实例与分页；获取单个事件的详情、参与者和回复状态；查询多个日历的忙碌时段以寻找空闲时间；创建单次、全天、快速和重复事件，可设置参与者、提醒、Meet 链接和可见性；更新事件并管理参与者；在日历之间移动事件；列出、获取和创建日历；删除事件、日历或清空日历中的全部事件。
适用场景
适合让助手代替用户安排、改期或查询会议，在提议时间前检查多个日历的可用性，或让工作流自动化读取日历状态以触发基于时间的操作。
运行要求
以本地进程方式运行（Docker 镜像，streamable-http 传输），仅限桌面环境。README 的故障排查提到 Authorization 承载令牌和 X-Mewcp-Credential-Id 请求头，以及需要 MewCP 账户并连接 Google 日历 OAuth 凭据；但清单未声明任何认证或环境变量，具体配置需向提供方确认。需要访问 Google 日历和提供方服务的网络。
安装前请注意
写入和删除类工具会作用于真实日历：delete_event、delete_calendar、clear_calendar 和 move_event 不可恢复或会造成干扰，README 要求调用前必须获得用户明确确认。创建或更新事件可能根据 send_updates 向参与者发送邀请或取消邮件。README 提到额度限制和付费方案，使用可能产生费用。凭据通过 Authorization 承载令牌和 X-Mewcp-Credential-Id 请求头传递；日历数据会发送给 Google 和提供方服务。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Mewcp Google Calendar，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

README

Schedule smarter — create, search, and manage Google Calendar events through AI.

A Model Context Protocol (MCP) server that exposes Google Calendar's API for creating, reading, updating, and deleting events and calendars.

Overview

The Google Calendar MCP Server provides full calendar management directly from AI workflows:

  • List, search, and retrieve events with rich filtering by time range, text, and recurrence
  • Create single, all-day, quick, and recurring events with attendees, reminders, and Meet links
  • Update events and manage attendees, then get before/after state in a single response
  • Query free/busy blocks across multiple calendars to find open slots without conflicts

Perfect for:

  • AI assistants that schedule, reschedule, and manage meetings on behalf of users
  • Workflow automation that reads calendar state to trigger time-based actions
  • Agents that coordinate availability and send invitations across teams

Tools

Events — Read

list_events — List events from a calendar

Lists events from a calendar within an optional time range. Returns events in start-time order. Recurring events are expanded into individual instances. Use ISO 8601 for time_min/time_max: 'YYYY-MM-DDTHH:MM:SSZ' (e.g. '2026-01-08T00:00:00Z'). Defaults to events from now onwards if time_min is not specified.

Inputs:

- `calendar_id` (string, optional, default: "primary") — Calendar ID. Use 'primary' for the user's main calendar- `max_results` (int, optional, default: 10) — Maximum number of events to return (1–2500)- `time_min` (string, optional, default: "") — Start of time range in ISO 8601 format, e.g. '2026-01-08T00:00:00Z'. Defaults to now- `time_max` (string, optional, default: "") — End of time range in ISO 8601 format, e.g. '2026-01-15T23:59:59Z'. Omit for open-ended- `query` (string, optional, default: "") — Free-text search query to filter events by title, description, or location- `show_deleted` (bool, optional, default: false) — Include cancelled events in results- `page_token` (string, optional, default: "") — Pagination token from a previous response's next_page_token to fetch the next page

Events — Write

create_event — Create a new calendar event

Creates a new calendar event and optionally invites attendees. For timed events use ISO 8601 datetime: '2026-01-08T14:30:00' with a timezone. For all-day events set is_all_day=True and use date-only format: '2026-01-08' — for all-day events end_time is exclusive, so a single-day event on Jan 8 needs end_time='2026-01-09'. Returns the created event with its ID.

Inputs:

- `summary` (string, required) — Event title- `start_time` (string, required) — Start time: ISO 8601 datetime e.g. '2026-01-08T14:30:00', or date e.g. '2026-01-08' for all-day events- `end_time` (string, required) — End time: ISO 8601 datetime or date. For all-day, end is exclusive: event on Jan 8 alone needs end_time='2026-01-09'- `calendar_id` (string, optional, default: "primary") — Calendar ID to create the event in. Use 'primary' for the user's main calendar- `description` (string, optional, default: "") — Event description or agenda- `location` (string, optional, default: "") — Event location. Enables map directions and 'time to leave' alerts in Google Calendar- `attendees` (list[string], optional, default: []) — Attendee email addresses. Invitation emails are sent per send_updates- `timezone` (string, optional, default: "UTC") — IANA timezone for the event, e.g. 'America/New_York'. Ignored for all-day events- `is_all_day` (bool, optional, default: false) — Set True for all-day events. Use date-only format (YYYY-MM-DD) for start_time and end_time- `color_id` (string, optional, default: "") — Color ID 1–11 for the event. Empty uses the calendar's default color- `visibility` (string, optional, default: "") — Event visibility: 'default', 'public', 'private', or 'confidential'. Empty uses calendar default- `transparency` (string, optional, default: "") — Free/busy status: 'opaque' (user shows as busy, default) or 'transparent' (user shows as free/available during this event)- `reminder_minutes` (int, optional, default: -1) — Minutes before event for a popup reminder (0–40320). Set -1 to use the calendar's default reminders- `send_updates` (string, optional, default: "all") — Who receives invitation emails: 'all' (everyone), 'externalOnly' (non-Google users only), 'none' (no emails)- `add_meet` (bool, optional, default: false) — Set True to automatically create a Google Meet video conference link for this event- `optional_attendees` (list[string], optional, default: []) — Email addresses of optional attendees. These people are invited but their attendance is not required- `guests_can_invite_others` (bool, optional, default: true) — Whether attendees can invite additional guests. Defaults to True per Google Calendar- `guests_can_modify` (bool, optional, default: false) — Whether attendees can modify the event. Defaults to False

update_event — Update an existing event

Updates an existing calendar event. Only the fields you provide are changed — leave a field empty to keep its current value. Fetches the current event first, applies changes, then saves. Use ISO 8601 for times: 'YYYY-MM-DDTHH:MM:SS'. For recurring events: pass the master recurring event ID to change all instances, or a specific instance ID to change only that occurrence. WARNING: do not update individual instances one-by-one to change the whole series — update the master event instead. Modifying instances individually creates exceptions that clutter the calendar and trigger excessive notifications. To cancel a single instance without affecting the rest of the series, set status='cancelled'.

Inputs:

- `event_id` (string, required) — ID of the event to update. For recurring events, use the master event ID to change all instances, or an instance ID to change only one occurrence- `calendar_id` (string, optional, default: "primary") — Calendar ID containing the event- `summary` (string, optional, default: "") — New event title. Leave empty to keep existing- `start_time` (string, optional, default: "") — New start time in ISO 8601 format. Leave empty to keep existing- `end_time` (string, optional, default: "") — New end time in ISO 8601 format. Leave empty to keep existing- `description` (string, optional, default: "") — New event description. Leave empty to keep existing- `location` (string, optional, default: "") — New event location. Leave empty to keep existing- `timezone` (string, optional, default: "") — Timezone for the updated start/end times, e.g. 'America/New_York'. Leave empty to keep the event's existing timezone- `status` (string, optional, default: "") — Event status: 'confirmed', 'tentative', or 'cancelled'. Set 'cancelled' on a recurring event instance ID to cancel only that occurrence without affecting the rest of the series- `transparency` (string, optional, default: "") — Free/busy status: 'opaque' (shows as busy) or 'transparent' (shows as free). Leave empty to keep existing- `reminder_minutes` (int, optional, default: -1) — Minutes before event for a popup reminder (0–40320). Set -1 to keep existing reminders- `send_updates` (string, optional, default: "all") — Who receives update notifications: 'all', 'externalOnly', or 'none'- `add_meet` (bool, optional, default: false) — Set True to add a Google Meet video conference link to this event. Has no effect if a Meet link already exists- `guests_can_invite_others` (bool, optional) — Whether attendees can invite additional guests. Leave unset to keep existing value- `guests_can_modify` (bool, optional) — Whether attendees can modify the event. Leave unset to keep existing value

Events — Delete

delete_event — Permanently delete an event

DESTRUCTIVE — REQUIRES EXPLICIT USER CONFIRMATION BEFORE CALLING. Permanently deletes a calendar event. This action is irreversible: the event, its attendees list, reminders, and all associated data are removed immediately and cannot be recovered. Attendees will receive cancellation emails (controlled by send_updates). For recurring events: deleting the master event ID removes the entire series and all its instances. Deleting a specific instance ID removes only that one occurrence. NEVER call this tool autonomously or as part of an automated flow. You MUST stop, tell the user the event title, date, and time that will be permanently deleted, and for recurring events clarify whether you are deleting one occurrence or the entire series, and wait for their explicit written confirmation before proceeding.

Inputs:

- `event_id` (string, required) — ID of the event to delete- `calendar_id` (string, optional, default: "primary") — Calendar ID containing the event- `send_updates` (string, optional, default: "all") — Who receives cancellation emails: 'all' (recommended), 'externalOnly', or 'none'

Output data schema:

typescript
{  message: string;}
move_event — Move an event to another calendar

DESTRUCTIVE — REQUIRES EXPLICIT USER CONFIRMATION BEFORE CALLING. Moves a default event from one calendar to another. Only events of type 'default' can be moved — birthday, focusTime, fromGmail, outOfOffice, and workingLocation events cannot be moved and will return an error. The event is removed from the source calendar and placed in the destination calendar — any calendar-specific settings, sharing permissions, or notification rules from the source will no longer apply. While technically reversible by moving back, this can disrupt other attendees and shared calendar visibility in ways that are hard to track down. NEVER call this tool autonomously. You MUST tell the user which event is being moved, from which calendar to which, and wait for their explicit confirmation.

Inputs:

- `event_id` (string, required) — ID of the event to move- `source_calendar_id` (string, required) — ID of the calendar currently containing the event- `destination_calendar_id` (string, required) — ID of the destination calendar

Output data schema:

typescript
{  id: string;  summary: string | null;  start: { date: string | null; dateTime: string | null; timeZone: string | null; };  end: { date: string | null; dateTime: string | null; timeZone: string | null; };  status: string | null;  htmlLink: string | null;  created: string | null;  updated: string | null;  description: string | null;  location: string | null;  colorId: string | null;  creator: { id: string | null; email: string | null; displayName: string | null; self: boolean | null; } | null;  organizer: { id: string | null; email: string | null; displayName: string | null; self: boolean | null; } | null;  recurrence: string[] | null;  recurringEventId: string | null;  originalStartTime: { date: string | null; dateTime: string | null; timeZone: string | null; } | null;  transparency: string | null;  visibility: string | null;  iCalUID: string | null;  sequence: number | null;  attendees: {    email: string;    id: string | null;    displayName: string | null;    organizer: boolean | null;    self: boolean | null;    resource: boolean | null;    optional: boolean | null;    responseStatus: string | null;    comment: string | null;    additionalGuests: number | null;  }[] | null;  attendeesOmitted: boolean | null;  guestsCanInviteOthers: boolean | null;  guestsCanModify: boolean | null;  guestsCanSeeOtherGuests: boolean | null;  hangoutLink: string | null;  conferenceData: object | null;  reminders: { useDefault: boolean; overrides: { method: string; minutes: number; }[] | null; } | null;  eventType: string | null;}

Calendars

list_calendars — List all calendars

Lists all calendars the user has access to. Returns calendar IDs, names, timezones, colors, and access roles. Use min_access_role to filter to calendars the user can write to.

Inputs:

- `min_access_role` (string, optional, default: "") — Minimum access role to filter by: 'freeBusyReader', 'reader', 'writer', or 'owner'. Empty returns all calendars- `show_hidden` (bool, optional, default: false) — Include calendars hidden from the list view- `max_results` (int, optional, default: 100) — Maximum number of calendars to return (1–250)- `page_token` (string, optional, default: "") — Pagination token from a previous response's next_page_token to fetch the next page

Output data schema:

typescript
{  count: number;  calendars: {    id: string;    summary: string;    description: string | null;    location: string | null;    timeZone: string | null;    accessRole: string | null;    backgroundColor: string | null;    foregroundColor: string | null;    selected: boolean | null;    primary: boolean | null;    hidden: boolean | null;  }[];  next_page_token: string | null;}
get_calendar — Get a single calendar

Gets full details of a specific calendar including its name, description, timezone, and color settings.

Inputs:

- `calendar_id` (string, optional, default: "primary") — Calendar ID. Use 'primary' for the user's main calendar

Output data schema:

typescript
{  id: string;  summary: string;  description: string | null;  location: string | null;  timeZone: string | null;  accessRole: string | null;  backgroundColor: string | null;  foregroundColor: string | null;  selected: boolean | null;  primary: boolean | null;  hidden: boolean | null;}
create_calendar — Create a new calendar

Creates a new calendar owned by the user. Returns the created calendar with its ID, which is needed for all subsequent operations on that calendar.

Inputs:

- `summary` (string, required) — Name of the new calendar- `description` (string, optional, default: "") — Optional description for the calendar- `timezone` (string, optional, default: "UTC") — IANA timezone name for the calendar, e.g. 'America/New_York'

Output data schema:

typescript
{  id: string;  summary: string;  description: string | null;  location: string | null;  timeZone: string | null;  accessRole: string | null;  backgroundColor: string | null;  foregroundColor: string | null;  selected: boolean | null;  primary: boolean | null;  hidden: boolean | null;}
delete_calendar — Permanently delete a calendar

DESTRUCTIVE — REQUIRES EXPLICIT USER CONFIRMATION BEFORE CALLING. Permanently deletes an entire calendar and every event it contains. This action is irreversible: all events, recurring series, and history in the calendar are gone immediately with no way to recover them. NEVER call this tool autonomously or as part of an automated flow. You MUST stop, tell the user exactly which calendar will be deleted and that all its events will be permanently lost, and wait for their explicit written confirmation before proceeding.

Inputs:

- `calendar_id` (string, required) — ID of the calendar to delete

Output data schema:

typescript
{  message: string;}
clear_calendar — Delete all events from a calendar

DESTRUCTIVE — REQUIRES EXPLICIT USER CONFIRMATION BEFORE CALLING. Permanently deletes ALL events from a calendar without deleting the calendar itself. This action is irreversible: every event in the calendar — past, present, and future — is removed immediately with no way to recover them. The calendar itself remains and can be used for new events. This is the only way to clear the primary calendar, which cannot be deleted. NEVER call this tool autonomously or as part of an automated flow. You MUST stop, tell the user exactly which calendar will be cleared and that every event in it will be permanently deleted, and wait for their explicit written confirmation before proceeding.

Inputs:

- `calendar_id` (string, required) — ID of the calendar to clear. Use 'primary' for the user's main calendar. WARNING: all events in this calendar will be permanently deleted

Output data schema:

typescript
{  message: string;}

Free/Busy

get_free_busy — Query busy blocks across calendars

Returns busy time blocks for one or more calendars within a time range. Use this to find when someone is available or to schedule without conflicts. Provide time_min and time_max in ISO 8601 format with timezone, e.g. '2026-01-08T09:00:00Z'. Returns a map of calendar ID → list of busy time blocks. Free time = gaps between the busy blocks within the requested range.

Inputs:

- `time_min` (string, required) — Start of the query window in ISO 8601 format, e.g. '2026-01-08T09:00:00Z'- `time_max` (string, required) — End of the query window in ISO 8601 format, e.g. '2026-01-08T17:00:00Z'- `calendar_ids` (list[string], optional, default: []) — Calendar IDs to query. Defaults to ['primary'] if empty

Output data schema:

typescript
{  timeMin: string;  timeMax: string;  calendars: {    [calendarId: string]: {      busy: {        start: string;        end: string;      }[];      errors: object[] | null;    };  };}

API Parameters Reference

Response Envelope

Every tool returns the same top-level envelope. Only data varies per tool.

typescript
// Success{  success: true;  statusCode: number;  retriable: false;  retry_after_seconds: null;  error: null;  data: { ... };   // schema shown per tool above}
// Error{  success: false;  statusCode: number;  retriable: boolean;  retry_after_seconds: number | null;  error: {    code: string;    // VALIDATION_ERROR | AUTH_ERROR | UPSTREAM_ERROR | SERVER_ERROR    message: string;    details: any;  };  data: null;}
  • retriable — true when it is safe to retry (rate limit, network error, 503). false for validation and auth errors.
  • retry_after_seconds — seconds to wait before retrying; present only when retriable is true and the upstream specifies a delay.
Date and Time Formats

All tools use ISO 8601 format for date and time values.

Timed events:

YYYY-MM-DDTHH:MM:SS         local time (requires timezone param)YYYY-MM-DDTHH:MM:SSZ        UTCYYYY-MM-DDTHH:MM:SS±HH:MM   explicit offset

All-day events (use with is_all_day=true):

YYYY-MM-DD    e.g. 2026-01-08

For all-day events, end_time is exclusive — a single-day event on Jan 8 needs end_time='2026-01-09'.

Recurrence Rules (RRULE)

create_recurring_event requires an RFC 5545 RRULE string starting with RRULE:.

RRULE:FREQ=DAILY;COUNT=5                     — 5 daily occurrencesRRULE:FREQ=WEEKLY;BYDAY=MO,WE,FR            — every Mon/Wed/FriRRULE:FREQ=MONTHLY;BYMONTHDAY=15            — 15th of each monthRRULE:FREQ=YEARLY                            — same date each yearRRULE:FREQ=WEEKLY;BYDAY=MO;UNTIL=20261231T000000Z  — until a date
Calendar ID
  • primary — the user's main Google Calendar (always valid)
  • All other calendars use a full ID from list_calendars, e.g. [email protected]

list_calendars returns id for every calendar the user has access to.

Pagination

list_events, search_events, list_event_instances, and list_calendars support pagination via next_page_token.

When data.next_page_token is non-null in a response, pass it as page_token in the next call with the same parameters to retrieve the next page.

Troubleshooting

Missing or Invalid Headers
  • Cause: OAuth token not provided in request headers or incorrect format
  • Solution:
    1. Verify Authorization: Bearer YOUR_TOKEN and X-Mewcp-Credential-Id: CREDENTIAL-ID headers are present
    2. Check the OAuth token has not expired — reconnect in your MewCP account if needed
Insufficient Credits
  • Cause: API calls have exceeded your request limits
  • Solution:
    1. Check credit usage in your Curious Layer dashboard
    2. Upgrade to a paid plan or add credits for higher limits
    3. Contact support for credit adjustments
Credential Not Connected
  • Cause: No Google Calendar credential linked to your account
  • Solution:
    1. Go to Credentials in your MewCP dashboard
    2. Connect your Google account (OAuth)
    3. Retry the request with the correct X-Mewcp-Credential-Id header
Malformed Request Payload
  • Cause: JSON payload is invalid or missing required fields
  • Solution:
    1. Validate JSON syntax before sending
    2. Ensure all required tool parameters are included
    3. Check parameter types match expected values (e.g. time_min must be ISO 8601)
Server Not Found
  • Cause: Incorrect server name in the API endpoint
  • Solution:
    1. Verify endpoint format: {server-name}/mcp/{tool-name}
    2. Use the correct server name from documentation
    3. Check available servers in your Curious Layer account
Google Calendar API Error
  • Cause: Upstream Google Calendar API returned an error
  • Solution:
    1. Check Google Workspace Status for service issues
    2. Verify your Google account has the required calendar permissions
    3. Review the error message in the response for specific details
