With its recent AI makeover, it can do more than just help you write code. You can connect your applications to it and let LLMs automate many of the mundane tasks in your workflow. In this guide, I will explain how to connect Google Calendar with VS Code in the most secure and robust way possible via Composio. ## Also integrate Google Calendar with - [ChatGPT](https://composio.dev/toolkits/googlecalendar/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/googlecalendar/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/googlecalendar/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/googlecalendar/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/googlecalendar/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/googlecalendar/framework/codex) - [Cursor](https://composio.dev/toolkits/googlecalendar/framework/cursor) - [OpenCode](https://composio.dev/toolkits/googlecalendar/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/googlecalendar/framework/openclaw) - [Hermes](https://composio.dev/toolkits/googlecalendar/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/googlecalendar/framework/cli) - [Google ADK](https://composio.dev/toolkits/googlecalendar/framework/google-adk) - [LangChain](https://composio.dev/toolkits/googlecalendar/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/googlecalendar/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/googlecalendar/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/googlecalendar/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/googlecalendar/framework/crew-ai) ## TL;DR ### Why use Composio? Composio provides: - Access to 1,000+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows. - Programmatic tool calling. Allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses. - Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need. ## Connect Google Calendar to VS Code ### Integrate Google Calendar MCP with VS Code ### 1. Install with one click Click the button below to add Composio to VS Code. You will be prompted to authorize. This requires VS Code 1.99+ with GitHub Copilot. [+Install in VS Code](vscode:mcp/install?%7B%22name%22%3A%22composio%22%2C%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fconnect.composio.dev%2Fmcp%22%7D) ### 2. Or add manually Open or create .vscode/mcp.json in your project root and add the following configuration: ```bash { "servers": { "composio": { "type": "http", "url": "https://connect.composio.dev/mcp" } } } ``` ## What is the Google Calendar MCP server, and what's possible with it? The Google Calendar MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google Calendar account. It provides structured and secure access to your calendars and events, so your agent can schedule meetings, create or modify events, list upcoming appointments, and manage calendars—all on your behalf. - Automated event creation and scheduling: Easily instruct your agent to add new events, meetings, or reminders with specific times, attendees, and details. - Event listing and agenda overview: Have your agent list all upcoming, past, or filtered events on any of your calendars to keep you on top of your schedule. - Calendar management and customization: Direct your agent to create new calendars, update calendar details, or even insert calendars into your list for better organization. - Event updating and deletion: Let your agent modify existing events or remove events that are no longer needed, keeping your calendar up to date. - Complete calendar clearing: Ask your agent to clear all events from a primary calendar or delete secondary calendars entirely when you need a fresh start. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `GOOGLECALENDAR_CALENDAR_LIST_INSERT` | Insert Calendar into List | Inserts an existing calendar into the user's calendar list. | | `GOOGLECALENDAR_CALENDAR_LIST_UPDATE` | Update Calendar List Entry | Updates an existing entry on the user\'s calendar list. | | `GOOGLECALENDAR_CALENDARS_DELETE` | Delete Calendar | Deletes a secondary calendar. use calendars.clear for clearing all events on primary calendars. | | `GOOGLECALENDAR_CALENDARS_UPDATE` | Update Calendar | Updates metadata for a calendar. | | `GOOGLECALENDAR_CLEAR_CALENDAR` | Clear Calendar | Clears a primary calendar. this operation deletes all events associated with the primary calendar of an account. | | `GOOGLECALENDAR_CREATE_EVENT` | 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. | | `GOOGLECALENDAR_DELETE_EVENT` | 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. | | `GOOGLECALENDAR_DUPLICATE_CALENDAR` | Create a calendar | Creates a new, empty google calendar with the specified title (summary). | | `GOOGLECALENDAR_EVENTS_INSTANCES` | Get Event Instances | Returns instances of the specified recurring event. | | `GOOGLECALENDAR_EVENTS_LIST` | List Events | Returns events on the specified calendar. | | `GOOGLECALENDAR_EVENTS_MOVE` | Move Event | Moves an event to another calendar, i.e., changes an event's organizer. | | `GOOGLECALENDAR_EVENTS_WATCH` | Watch Events | Watch for changes to events resources. | | `GOOGLECALENDAR_FIND_EVENT` | 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. | | `GOOGLECALENDAR_FIND_FREE_SLOTS` | 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. | | `GOOGLECALENDAR_FREE_BUSY_QUERY` | Query Free/Busy Information | Returns free/busy information for a set of calendars. | | `GOOGLECALENDAR_GET_CALENDAR` | Get Google Calendar | Retrieves a specific google calendar, identified by `calendar id`, to which the authenticated user has access. | | `GOOGLECALENDAR_GET_CURRENT_DATE_TIME` | Get current date and time | Gets the current date and time, allowing for a specific timezone offset. | | `GOOGLECALENDAR_LIST_ACL_RULES` | 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. | | `GOOGLECALENDAR_LIST_CALENDARS` | List Google Calendars | Retrieves calendars from the user's google calendar list, with options for pagination and filtering. | | `GOOGLECALENDAR_PATCH_CALENDAR` | 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. | | `GOOGLECALENDAR_PATCH_EVENT` | 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. | | `GOOGLECALENDAR_QUICK_ADD` | Quick Add Event | 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'. | | `GOOGLECALENDAR_REMOVE_ATTENDEE` | Remove attendee from event | Removes an attendee from a specified event in a google calendar; the calendar and event must exist. | | `GOOGLECALENDAR_SETTINGS_LIST` | List Settings | Returns all user settings for the authenticated user. | | `GOOGLECALENDAR_SETTINGS_WATCH` | Watch Settings | Watch for changes to settings resources. | | `GOOGLECALENDAR_SYNC_EVENTS` | 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. | | `GOOGLECALENDAR_UPDATE_ACL_RULE` | Update ACL Rule | Updates an access control rule for the specified calendar. | | `GOOGLECALENDAR_UPDATE_EVENT` | Update Google event | Updates an existing event by `event id` in a google calendar;

Returns the event ID, change type, and the specific fields that changed with their previous and new values. | ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, VS Code can access the Google Calendar MCP server via Composio to run the app actions you authorize, directly from your coding workflow. ## Complete Code None listed. ## Conclusion ### Way Forward Now that Google Calendar is connected, extend your setup by connecting the other apps you already use every day, so your agent can run true cross-app workflows end to end. - Connect Calendar to turn threads into scheduled meetings automatically. - Connect Slack or Teams to post summaries, approvals, and alerts where your team works. - Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs. - Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps. - Connect HubSpot or Salesforce to log customer context, update records, and draft follow-ups. Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single MCP endpoint, your agent can coordinate multiple tools safely and reliably in one conversation. ## How to build Google Calendar MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/googlecalendar/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/googlecalendar/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/googlecalendar/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/googlecalendar/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/googlecalendar/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/googlecalendar/framework/codex) - [Cursor](https://composio.dev/toolkits/googlecalendar/framework/cursor) - [OpenCode](https://composio.dev/toolkits/googlecalendar/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/googlecalendar/framework/openclaw) - [Hermes](https://composio.dev/toolkits/googlecalendar/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/googlecalendar/framework/cli) - [Google ADK](https://composio.dev/toolkits/googlecalendar/framework/google-adk) - [LangChain](https://composio.dev/toolkits/googlecalendar/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/googlecalendar/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/googlecalendar/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/googlecalendar/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/googlecalendar/framework/crew-ai) ## Related Toolkits - [Apaleo](https://composio.dev/toolkits/apaleo) - Apaleo is a cloud-based property management platform for hospitality businesses.

With a standalone Google Calendar MCP server, the agents and LLMs can only access a fixed set of Google Calendar tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Google Calendar and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with VS Code? Yes, you can. VS Code fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Google Calendar tools. ### Can I manage the permissions and scopes for Google Calendar while using Tool Router? Yes, absolutely. You can configure which Google Calendar scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Google Calendar data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
