After sharing how to use Graph Explorer for quick Microsoft 365 API access, I've packaged three ready-to-use skills that make Claude Code integration even simpler.

Three Skills, Three Complexity Levels

Choose the one that matches your needs:

  1. ms-graph-toolkit - Full-featured Python integration with comprehensive M365 capabilities (calendar, email, Teams, OneDrive, organizational intelligence)
  2. ms-graph-search-sdk - Lightweight Python implementation focused on search and queries across M365 services
  3. ms-graph-search - Minimal bash/curl implementation for quick queries and learning the Graph API without dependencies

Quick Setup

Getting started takes about 60 seconds:

# 1. Grab the skills from GitHub
git clone https://github.com/pauljsnider/ai-config-guide.git
cd ai-config-guide/claude/skills

# 2. Copy to your Claude skills directory
cp -r ms-graph-* ~/.claude/skills/

# 3. Check the README files for authentication setup
cat ~/.claude/skills/ms-graph-toolkit/README.md

Then tell Claude to use the MS Graph skill for your M365 tasks.

What You Can Build

The skills enable dynamic script generation. Just describe what you want, and Claude builds it on demand. Here are proven use cases:

Meeting Intelligence

  • Pre-meeting intel - Auto-brief on attendees with past conversation history, shared files, and collaboration patterns
  • Meeting hygiene audit - Identify no-agenda meetings, detect burnout patterns, calculate time waste metrics
  • Meeting pattern org chart - Map real influence networks versus official hierarchy

Knowledge Discovery

  • Find the expert - Who in the company knows most about topic X based on files, emails, and Teams activity?
  • Resurrect dead projects - Generate timelines of what happened and who was involved from archived conversations
  • Forgotten file finder - Surface documents that were shared but never acted upon

Workflow Automation

  • Weekly digest - Unread emails, @mentions, shared files, missed meeting recordings in one summary
  • Auto-decline focus time - Protect deep work blocks, suggest alternative times automatically
  • Smart travel mode - Set OOO blocks, update status, suggest local colleagues to connect with
  • Auto weekly status - Generate "what I did" reports from calendar, tasks, and file activity

Network & Insights

  • Network recommendations - Who should you meet based on collaboration pattern analysis?
  • Inbox sentiment analysis - Track communication tone trends over time
  • Meeting cost calculator - Calculate actual cost of recurring meetings based on attendee salaries

How It Works

Each skill includes authentication helpers, common query templates, and the ability to generate custom scripts on the fly. Claude reads your request, determines the required Graph API calls, builds the script, and executes it.

The skill builds new scripts on demand - just describe what you want. No need to learn the Graph API syntax or worry about authentication flows.

Security Considerations

When using these skills, keep these security best practices in mind:

⚠️ Access Token Lifespan: Graph Explorer tokens typically expire after 60-90 minutes. This is a security feature, not a bug. Plan your automation sessions accordingly and be prepared to refresh tokens for longer workflows.
  • Treat tokens like passwords - Never commit them to git repos, share them in chat, or store them in plain text files
  • Use environment variables - Store tokens in environment variables or secure credential stores, not hardcoded in scripts
  • Scope to minimum permissions - Only consent to the permissions your task actually needs
  • Rotate regularly - Even though tokens expire automatically, refresh them proactively for sensitive operations
  • Monitor usage - Check Azure AD sign-in logs periodically to verify no unexpected token usage
  • Production apps need proper OAuth - These skills are for prototyping and personal automation. Production applications should implement proper app registration with OAuth flows

The short token lifespan is intentional - it limits the blast radius if a token is accidentally exposed. For longer-running automation, consider implementing proper OAuth refresh token flows in production environments.

Next Steps

Visit the skills repository to grab the code and check the README files for authentication setup. Each skill includes examples and usage patterns to get you started.

Start with ms-graph-search if you want to learn the basics, upgrade to ms-graph-search-sdk for production use, or jump straight to ms-graph-toolkit if you need comprehensive M365 integration.
