Outlook Calendar MCP Pack

Part of Pipeworx — an MCP gateway connecting AI agents to 1481+ live data sources.

Tools

Tool

Description

list_events

List upcoming events from the user's Outlook / Microsoft 365 calendar within a time window. Returns subject, start/end times, location, organizer, all-day flag, and online meeting URL for each event. Defaults to the next 7 days. Use to see what meetings or appointments are scheduled.

get_event

Get full details of a single Outlook / Microsoft 365 calendar event by its ID. Returns subject, start/end times, location, organizer, attendees, body, all-day flag, and online meeting URL. Use after list_events to inspect a specific meeting.

list_calendars

List all calendars accessible in the user's Outlook / Microsoft 365 account. Returns each calendar's ID, name, owner, edit permission, and whether it is the default calendar. Use to discover which calendars exist.

find_meeting_times

Return the user's busy time windows from their Outlook / Microsoft 365 calendar over the next N days — a lightweight free/busy view. Each window includes start, end, subject, and all-day flag. Use to find when the user is available or to identify scheduling conflicts before proposing a meeting time.

get_profile

Get the signed-in user's Microsoft 365 / Outlook profile: display name, primary email (mail), and user principal name. Use to confirm whose calendar is connected.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "outlook_calendar": {
      "url": "https://gateway.pipeworx.io/outlook_calendar/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/outlook_calendar/mcp returns the tools in the table above plus the shared Pipeworx meta-toolsask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1481+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Outlook Calendar data" })

The gateway picks the right tool and fills the arguments automatically.
