Usage with VS Code

Local Node.js

You can run the MCP server directly with Node.js from your local build:

1. Clone the repository and build the project:

git clone https://github.com/anoopt/outlook-meetings-scheduler-mcp-server.git
cd outlook-meetings-scheduler-mcp-server
npm install
npm run build

2. For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open User Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others:

{
  "mcpServers": {
    "outlook-meetings-scheduler": {
      "command": "node",
      "args": [
        "/path/to/outlook-meetings-scheduler-mcp-server/build/index.js"

Example Scenarios

Integration with GitHub MCP Server

You can combine this MCP server with other MCP servers like the GitHub MCP server for powerful workflows.

Create an Issue and Schedule a Follow-up Review

Create an issue in the organization/repo repository titled "Fix pagination bug in user dashboard" with the description "Users report seeing duplicate entries when navigating between pages." Then schedule a calendar reminder for me to review this issue tomorrow at 3 PM.

This will:

1. Use the GitHub MCP server to create the issue
2. Use the Outlook Meetings Scheduler MCP server to create a calendar event for the review

Schedule a Code Review Meeting Based on a Pull Request

Find the open PR about the authentication feature in the organization/app-backend repository and schedule a code review meeting with the contributors for tomorrow morning.

This will:

1. Use GitHub MCP server to find the pull request and identify contributors
2. Use the Outlook Meetings Scheduler MCP server to schedule a meeting with those team members

Configuration for Multi-MCP Setup

To use both GitHub and Outlook MCP servers together :

{
  "mcpServers": {
    "outlook-meetings-scheduler": {
      "command": "npx",
      "args": [
        "-y",
        "outlook-meetings-scheduler"
      ],
      "env": {
        "CLIENT_ID": "<YOUR_CLIENT_ID>",
        "CLIENT_SECRET": "<YOUR_CLIENT_SECRET>",
        "TENANT_ID": "<YOUR_TENANT_ID>",
        "USER_EMAIL": "<YOUR_EMAIL>"
      }
    },
    "github": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/github-mcp"
      ],
      "env": {
        "GITHUB_TOKEN": "<YOUR_GITHUB_TOKEN>"
      }
    }
  }
}

Direct Usage

Finding a Colleague's Email

I need to schedule a meeting with John Smith. Can you find his email address?

Creating a Simple Calendar Event

Schedule a meeting titled "Weekly Team Sync" for next Monday at 10 AM with the following agenda:
- Project updates
- Resource allocation
- Questions and concerns

Scheduling a Meeting with Single Attendee

Schedule a 1:1 meeting with Sarah for tomorrow at 3 PM.

This will find Sarah's email address and create a calendar event. To find Sarah's email address, the MCP server will use the find-person tool - which uses the Microsoft Graph API to find relevant people for USER_EMAIL or searches for the name in the organization.

Scheduling a Meeting with Multiple Attendees

Create a meeting called "Project Kickoff" for tomorrow at 2 PM. 
Add sarah.jones@example.com and mike.thompson@example.com as required attendees.
The agenda is:
1. Project overview
2. Timeline discussion
3. Role assignments
4. Next steps
