"An overview of knowledge graphs" matching MCP servers:

Enables AI apps to manage Google Calendar in plain language, including reviewing schedules, creating and changing events with guests and Google Meet, finding free time, and blocking Out of Office or Focus Time.

An MCP server for Microsoft Graph, exposing 60 tools across calendar, email, meetings, Teams chat, files, people, directory, tasks, and OneNote over stdio or Streamable HTTP.

Provides verified ANZ public holidays, school terms, and business-day calculations for all 9 regions of Australia and New Zealand, backed by data for 2026 and 2027.

Connects Claude to an OurFamilyWizard account, enabling natural-language access to co-parenting messages, calendars, expenses, and journal entries — including reading folders and drafts, syncing, and creating events or messages with confirmation safeguards.

An MCP server that provides 49 tools to access Microsoft Outlook for Mac, enabling management of mail, calendar, contacts, tasks, and notes via AppleScript.

Your real mailbox and calendar for your AI agent — Microsoft 365 via Graph or any IMAP — as 24 tools: read, search, attachments as text, sender history, drafting from identity and knowledge files, free-slot computation. Send, reply, delete and calendar writes need out-of-band human approval: the agent cannot approve its own actions.

Enables offline, fully local lookups and validations tuned for Chinese development work: statutory holiday and adjusted-workday checks, workday arithmetic, ID card/USCC/mobile format validation, Chinese-to-pinyin conversion, lunar-solar date conversion, and administrative region queries. It also provides searchable summaries of common uni-app, mini program, Element Plus, and Vant APIs, so assistants can answer these questions without any network calls or third-party services.

Provides reusable MCP tools for Amazon Connect AI Agents and Bedrock AgentCore to look up customers, manage support tickets, schedule appointments, update CRM records, retrieve knowledge, and create tasks.

An MCP server that gives Claude Code and Codex full control of a personal Outlook.com mailbox and calendar via the Microsoft Graph API, enabling mail, draft, folder, and calendar operations through natural language.

Enables AI agents to read and manage Microsoft 365/Outlook email and calendar, with destructive actions (send email, create event) requiring human approval.

MCP server for Open-Xchange & standards-based mail: email (IMAP/SMTP), Sieve filters, CalDAV calendar, CardDAV contacts, free/busy.

Enables comprehensive Google Meet and Calendar management through Google Calendar API v3 and Google Meet API v2, supporting calendar event creation with Meet links, space management, transcription, recording, attendance tracking, and meeting moderation controls.

Exposes availability and appointment-proposal tools over stdio so an MCP client can query open slots and suggest bookings, without being able to create them—actual booking requires human confirmation through the separate UI/API. Slot claims are transactional and idempotent, and cancellation only releases a slot still owned by that booking.

Exposes a personal AI concierge's calendar and send_email tools over MCP, letting AI clients book Calendly meetings and send messages to the owner's inbox.

Mu is an MCP server and web app that provides agents and humans access to real-world services like news, web search, mail, markets, weather, video, places, images, files, calendar, and contacts. It offers a wide range of tools and can be self-hosted or used live at micro.mu.

Enables managing calendars, tasks, and contacts on an existing Radicale CalDAV/CardDAV server via MCP.

Enables read-only access to an explicit set of pre-configured CalDAV calendars, letting an agent list configured calendars, search and list events across a bounded time range or by text query, and fetch individual events by UID without any write capability.

Enables read-only access to the local Apple Calendar on macOS through an MCP client, allowing retrieval of today's events, events for a specific date, or events in a date range. It supports optional calendar filtering and keeps calendar data local.

An Alexa+ MCP server that turns household emails and photographed notices into a shared list of bills, appointments, deliveries, and renewals, with source quotes and privacy controls.
