# Google Calendar — AI Connector Google Calendar publishes 8 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/productivity/google-calendar/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Productivity](https://node8.ai/ai-connectors/productivity/) # Google Calendar Calendar reads, scheduling and invitation responses in Google Calendar Listed in Claude · 8 published tools · Verified partner [Claude connector docs](https://developers.google.com/workspace/calendar) [cloud.google.com](https://cloud.google.com) Overview ## What Google Calendar does The Google Calendar connector covers viewing a schedule, checking availability across one or more calendars, creating and updating events, responding to invitations, and reading attendee details before a meeting. Finding a mutual free slot across several people is handled by the server rather than by fetching every calendar and comparing them in the conversation. The connector is published by Google and carries partner tier. A Google account authorisation is required, after which the reachable set matches the calendars that account can already see. Eight tools are claimed; the endpoint returned nine. ### Who it is for Anyone whose working calendar is in Google Calendar. ### Tool surface Nine observed tools against eight claimed, and the split is close to even: list\_events, get\_event, list\_calendars, search\_events and suggest\_time read, while create\_event, update\_event, delete\_event and respond\_to\_event write. Availability ## Where Google Calendar is listed Google Calendar is listed in the Claude connectors directory only. Google has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Google Calendar publishes 8 tools to Claude. That is a mid-sized surface: 37.7% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Productivity publishes 12, so this one sits 4 tools below its bucket's median, 278th of 462. It falls in the 7-10 tools band, which holds 14.6% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 9 tools, 1 more than the 8 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `list_events` - `get_event` - `list_calendars` - `suggest_time` - `create_event` - `update_event` - `delete_event` - `respond_to_event` - `search_events` Google Calendar publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Google Verification Verified partner (37.8% of the Claude directory) Filed under Productivity Endpoint `https://calendarmcp.googleapis.com/mcp/v1` Documentation [Publisher setup docs](https://developers.google.com/workspace/calendar) Published tools 8 · 7-10 tools band Depth rank in Productivity 278 of 462 Snapshot August 2026 Google Calendar carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How Google describes it > Connect Google Calendar to Claude to view your schedule, manage events, and coordinate meetings. Claude can search your calendar for events, check your availability, find free time slots, create and update events, respond to invitations, and help you prepare for meetings. Useful for understanding what's coming up, scheduling new meetings by finding mutual availability, managing your calendar by creating or updating events, coordinating schedules across multiple people, or preparing for meetings by reviewing attendee lists and details.
