"How to perform SELECT queries in PostgreSQL" matching MCP servers:

An OAuth-secured remote MCP server (22 tools) that lets Claude, ChatGPT, and Codex search All-In Summit attendee profiles, explore the live agenda, check sessions and meetings, detect scheduling conflicts, and export a calendar. Account-changing actions are only prepared for review, with the user confirming each request in the browser before any event API call is made.

Enables voice-driven family check-ins and safety escalation through five MCP tools over Streamable HTTP, recording check-ins, scheduling recurring reminders with grace windows, detecting missed check-ins, raising critical help alerts, and resolving them from a live dashboard. All reads and writes flow through these tools into a SQLite store, with safety rules ensuring explicit help requests override upbeat wording and never duplicate or downgrade alerts.

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 reading, creating and editing events in selected Nextcloud calendars over CalDAV, with credentials kept in a desktop keyring wallet rather than project files. Supports calendar listing, bounded event queries, structured event details, non-recurring event creation, and revision-checked patching of titles, descriptions, locations and times.

Read-only MCP server for Gingr pet-care facility data, enabling queries about owners, animals, reservations, appointments, services, and staff via natural language.

This project implements a Python-based MCP (Model Context Protocol) server that acts as an interface between Large Language Models (LLMs) and the Google Calendar API. It enables LLMs to perform calendar operations via natural language requests.

Enables AI assistants to perform Google Workspace administrative actions via GAM7, managing users, groups, calendar, Drive, and more.

Enables Claude to connect unlimited Gmail and IMAP mailboxes, search and triage them together while identifying each account, read attachments, and create drafts or perform permitted mailbox actions under configurable safety modes.

An MCP App that renders an interactive dashboard in Claude conversations to unify calendar events, emails, and documents into a single interface. It enables users to manage their daily schedule and perform actions like meeting preparation through bidirectional communication between the UI and the model.

Integrates the YearAtAGlance calendar with AI assistants to manage events, categories, and event density heatmaps. It enables users to perform CRUD operations on calendar data and utilize AI-powered features like natural language milestone creation and yearly analysis.

Enables AI assistants to read, send, and manage emails, calendars, and contacts in a Fastmail account via the JMAP protocol.

Enables AI assistants to perform Japanese business calendar calculations including holiday detection, business day arithmetic, payment date settlement, and deadline management using local data.

Enables users to get and set meeting appointments in Google Calendar.

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.

Enables Claude to interact with Canvas LMS, allowing natural language queries about courses, deadlines, grades, and feedback.

Provides comprehensive integration with Microsoft Outlook for managing emails, contacts, calendars, and folders through the Microsoft Graph API. It offers 26 specialized tools to perform actions like sending emails, scheduling meetings, and organizing mail folders.

Enables AI assistants to connect directly to Saigon University's academic portal for natural-language queries about schedules, exams, grades, GPA simulation, tuition, course offerings, notifications, and graduation progress.

An unofficial MCP server that enables adding content to daily notes, creating notes, saving links, and scheduling reminders in Reflect from Claude Desktop.

A Model Context Protocol (MCP) server for Google Calendar integration in Claude Desktop, enabling AI assistants to manage Google Calendar events through natural language interactions.

A lightweight MCP server for Apple Calendar on macOS that uses a Swift helper to access EventKit directly, enabling event queries without AppleScript or Calendar.app dependency.
