"Two agents working simultaneously" matching MCP servers:

Enables agents to list CalDAV calendars, query events by time range, and create, update, or delete events while keeping credentials in environment variables and never exposing passwords in responses.

MCP server for the Indico meeting agenda system, enabling AI agents to search event categories, browse agendas, and extract contribution and session details. Works with multiple Indico instances simultaneously.

Gives MCP clients access to Google Workspace (Gmail, Drive, Calendar, Sheets, Docs, etc.) across multiple Google accounts simultaneously.

Enables AI assistants to read and create Fantastical calendar events on macOS using local database access and URL schemes, working entirely offline without API keys or network access.

Enables LLM agents to query current time, DST schedules, timezone conversions, working hour overlaps, and meeting time suggestions across locations via the production findtime.io Time API, including natural-language time questions and location resolution.

Enables accurate calculation of Korean public holidays, substitute holidays, and business days, with tools to check dates, list holidays, and compute working-day intervals. It works as a public MCP connector requiring no authentication or API keys.

A timezone-aware MCP server that converts times, looks up current local times, and finds overlapping working-hour slots for distributed teams.

Enables AI agents to find auspicious windows for launches, travel, weddings, purchases, publications, and other events using Vedic electional astrology, and to retrieve panchanga, planetary hours, and Rahu Kala.

Provides deterministic, byte-stable temporal reference data over MCP, resolving civil dates and names into calendars, seasons, moon phases, planetary retrogrades, and traditional symbolic systems. Exposes tools that return a single date's identity, compare two dates across shared symbolic systems, and map a name to cosmic cards and Latin cipher sums, with coverage focused on 1900–2100.

Enables AI agents to manage household schedules by checking availability, proposing minimal changes, and requiring explicit human approval before executing any action.

A system integrating two independent MCP servers for Google Calendar and Google Tasks APIs, orchestrated by an LLM agent loop with a web dashboard.

Scheduling and booking engine for AI agents. Check availability, hold slots, and confirm appointments with two-phase booking and conflict-free resource management.

Enables scheduling meetings and sending email confirmations through Google Calendar and Gmail APIs. Provides secure OAuth authentication, policy enforcement for working hours, and prevents scheduling conflicts.

Enables LLM clients to look up, search, and count day-by-day academic schedule data for the Chennai campus AY 2026-27, including class-day progression (CD01–CD90), commencement, midterm and end-semester exam dates, holidays, faculty feedback and committee meetings, and working-Saturday timetable swaps. It also exposes the same dataset as an OpenAPI 3.1 REST API and serves the tools over stdio or SSE transports.

A self-hosted MCP server that provides secure access to iCloud Mail, Calendar, and Contacts, enabling agents to read and send email, manage calendar events, and search contacts with safety controls like approval for outgoing messages.

Enables AI agents to read and send email, handle attachments and manage calendar invitations through their own IMAP/SMTP mailboxes, with per-mailbox sender and recipient allow lists and automatic HTML-to-Markdown conversion. It runs as a single self-hosted Docker container, exposing the same tools over MCP and REST.

MCP server for the Shiftyasan public solver API, letting AI agents validate and solve shift-scheduling problems, with async job polling for large cases.

Enables agents to read, create, update, and delete iCloud Calendar events, including recurring events, via CalDAV.

Enables AI agents to look up businesses, find free appointment slots, book, list and cancel appointments at salons, barbershops, nail and brow studios and clinics. Works read-only without a customer login by returning a pre-filled booking link, and can also run against a built-in demo with sample businesses.

Create scheduling polls (like Doodle) from AI agents. Find the best time for meetings, dinners, and events. 5 tools: create_poll, get_poll, vote_on_poll, get_results, finalize_poll. No authentication required.
