"Connecting Firebase to a data source or application" matching MCP servers:

Enables voice assistants to find nearby service providers, connect users to live video representatives for natural conversation, and handle appointment booking. It also returns confirmed bookings so the assistant can add them to its calendar.

A stateless MCP server that forwards calendar operations to a CalDAV server, enabling AI assistants to list, search, create, update, delete events, and query free/busy information via encrypted tokens.

Enables AI agents to browse, search, and book meeting rooms across multiple buildings with realistic seed data and conflict detection.

Enables AI assistants to interact with Microsoft 365 and Office services through the Microsoft Graph API, providing tools for email, calendar, files, Teams, SharePoint, and more with configurable permissions and output formats.

Enables agents to interact with a clinic booking API, including listing specialties, doctors, and a patient's appointments, and booking or cancelling appointments when the active profile permits, while preserving the caller's authority and screening tool descriptions for safety.

Muslim Prayer Reminder MCP is a free, open-source server for calculated Muslim prayer times in AI assistants. It supports location and regional calculation methods, daily timetables, next-prayer countdowns, and local or remote MCP clients.

Enables Claude (or any MCP client) to read and write events on your iCloud calendars via CalDAV.

Enables Claude to manage a service business front desk by searching customers, checking real-time availability, creating and canceling appointments without double-booking, and generating revenue reports from actual data.

Enables AI assistants to read a student's own university academic data — class timetables, exam schedules, grades, available terms, and empty classrooms — from Qiangzhi (jsxsd) or Zhengfang V9 systems via a session imported from the browser. All access is strictly read-only, never performing course selection, withdrawal, or evaluations.

Enables MCP clients to access Stardew Valley calendar data, including current date, daily events, villager birthdays, weekly birthdays, and full seasonal calendars, through a local HTTP bridge to the HelloStardew mod. It provides read-only tools with structured success or error responses for natural-language use.

Provides read-only access to Hostaway PMS data, enabling assistants to answer questions about listings, calendars, reservations, and inbox threads, and generate occupancy, inbox, and completeness reports without writing or sending anything.

Enables AI agents to browse customers, bookings, and availability while any booking creation or cancellation stays gated behind a human-approved, single-use token cryptographically bound to the exact arguments. Runs over stdio or Streamable HTTP and enforces the read/write separation in host code with a full audit trail.

Enables students to view their courses, assignments and deadlines, review past submissions, and retrieve or save copies of their own uploaded files without making any changes to stored data.

A read-only MCP server that exposes a published iCalendar feed as calendar-query tools, enabling users to list events, view today/upcoming schedules, search events, and inspect feed info without OAuth or admin consent. Recurring events are expanded into individual occurrences on query.

Gives AI assistants direct, on-demand access to McGill's public Visual Schedule Builder timetable data, letting them search course offerings, fetch sections and meeting times, check conflicts, and generate ranked schedule combinations without a login, API key, or browser session. Queries and schedule calculations run locally on structured results, with a short-lived cache for repeated requests.

Enables MCP clients to search availability, read services, resources, bookings and customers, and, when writes are enabled, reserve slots, create or cancel bookings, and add or update customers.

A local MCP server for on-premises Microsoft Exchange, connecting via EWS and NTLM. It provides mail, template, availability, and calendar workflow tools through stdio, with draft-first safety and Windows Credential Manager integration.

The Outlook Calendar MCP enables Claude to directly manage Microsoft Outlook calendars on Windows systems, offering a privacy-focused solution that keeps all data local. Users can view events, create meetings, find free time slots, and manage multiple calendars without their data leaving their machi

Gives time-blind LLMs and agent frameworks a real clock: current time and timezone, elapsed task duration, countdowns to deadlines, timezone conversion, session heartbeats, cron-style due checks, and session-level timers. This lets locally hosted or self-built models stop hallucinating the time and actually perceive how long a task or conversation has been running.

Lets Claude, ChatGPT and other MCP clients read a Bookwhen account's public booking data, including events (classes, courses, workshops), ticket types with availability and cost, locations, class passes, leaders and attachments. It is read-only, so it can never modify data or expose attendee or booking records.
