Microsoft Agent - A2A | AG-UI | MCP

Version: 0.1.2

Overview

Microsoft Graph MCP Server + A2A Supervisor Agent

It includes a Model Context Protocol (MCP) server that wraps the Microsoft Graph API and an out-of-the-box Agent2Agent (A2A) Supervisor Agent.

Manage your Microsoft 365 tenant (Users, Groups, Calendars, Drive, etc.) through natural language!

This repository is actively maintained - Contributions are welcome!

Capabilities:

• Comprehensive Graph API Coverage: Access thousands of Microsoft Graph endpoints via MCP tools.
• Supervisor-Worker Agent Architecture: A smart supervisor delegates tasks to specialized agents (e.g., Calendar Agent, User Agent).
• Secure Authentication: Supports OAuth, OIDC, and other authentication methods.

MCP

MCP Tools

This server provides tools for a vast array of Microsoft Graph resources. Due to the large number of tools, they are organized by resource type.

Supported Resources (Partial List):

• Users: get_user, update_user, list_user, etc.
• Groups: get_group, post_groups_group, list_members_group, etc.
• Calendar: get_calendar, post_events, list_calendarview, etc.
• Drive/DriveItems: get_drive, search_driveitem, upload_driveitem, etc.
• Mail: send_mail, list_messages, etc.
• Directory Objects: get_directoryobject, check_member_objects, etc.
• Planner, OneNote, Teams, and more.

All tools generally follow the naming convention: action_resource (e.g., list_user, delete_group).

Using as an MCP Server

The MCP Server can be run in two modes: stdio (for local testing) or http (for networked access).

Run in stdio mode (default):

microsoft-agent --transport "stdio"

Run in HTTP mode:

microsoft-agent --transport "http"  --host "0.0.0.0"  --port "8000"

AI Prompt:

Find who manages the 'Engineering' group and list its members.

AI Response:

I've found the 'Engineering' group.
Owners:
- Jane Doe (Head of Engineering)

Members:
- John Smith
- Alice Johnson

A2A Agent

This package includes a powerful A2A Supervisor Agent that orchestrates interaction with the Microsoft MCP tools.

Architecture

The system uses a Supervisor Agent that analyzes user requests and delegates them to domain-specific Child Agents.

Loading

Component Interaction

1. User sends a request (e.g., "Schedule a meeting with the Engineering team").
2. Supervisor Agent identifies this as a calendar and group task.
3. Supervisor delegates finding the group members to the Group Agent.
4. Group Agent calls list_members_group tool and returns emails.
5. Supervisor delegates scheduling to the Calendar Agent with the retrieved emails.
6. Calendar Agent calls post_events tool.
7. Supervisor confirms completion to the User.
