Apps & Automation
View on GitHub

Work with Microsoft 365 services via the Graph API — emails, calendar events, SharePoint sites (read and write), Teams chats and channel messages, OneDrive files, OneNote notebooks, Planner task boards, Microsoft To Do task lists, AI meeting insights (Copilot recap), contacts, and org chart. Use this skill whenever the user asks about their emails, inbox, unread messages, meetings, calendar, Teams messages or chats, channel messages, SharePoint documents, OneDrive files, OneNote notes or notebooks, Planner plans or tasks, "my tasks", to-do lists, action items, meeting summaries, colleagues, manager, direct reports, or any personal/organizational Microsoft data. Invoke proactively any time the user mentions Outlook, Teams, SharePoint, OneDrive, OneNote, Planner, Microsoft To Do, or wants to interact with their Microsoft 365 account. The skill uses a local Node.js CLI (msgraph.js) that handles authentication, token caching, and all API calls.

Microsoft Graph API Skill

This skill lets you interact with Microsoft 365 services on behalf of the user using the Microsoft Graph API. The Node.js CLI at scripts/msgraph.js handles everything — no Python or extra packages needed, only the Node.js that CodeMie already requires.

Setup & Authentication

Check login status first — always run this before any other command:

node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js status

Output interpretation:

  • Logged in as: user@company.com → proceed with any command below
  • NOT_LOGGED_IN → follow the Login Flow below
  • TOKEN_EXPIRED → session expired, also follow the Login Flow below

Login Flow (first time or after expiry)

node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js login

This opens the system browser for Microsoft authentication (PKCE flow). If the browser does not open automatically, a URL will be printed in the terminal — navigate to it manually. After successful sign-in, the token is cached at ~/.ms_graph_token_cache.json and all subsequent commands run silently.

Use --force to re-authenticate even when already logged in:

node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js login --force

When NOT logged in or token expired

If status returns NOT_LOGGED_IN or TOKEN_EXPIRED, tell the user:

"You need to log in to Microsoft first. Run this command in your terminal:

node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js login

Your browser will open for Microsoft sign-in. If it doesn't open automatically, a URL will appear in the terminal — navigate to it to complete authentication."

# Machine-readable JSON output
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js onenote --notebooks --json

Planner

Team/group task boards. Plans live inside Microsoft 365 groups, so --plans needs the Group.Read.All scope. Updates use optimistic concurrency under the hood (etag handling is automatic).

# List all plans shared with you (one call)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js planner --plans

# Tasks assigned to you across all plans (the usual starting point)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js planner --my-tasks

# List tasks in a specific plan (use ID from --plans)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js planner --plan-id PLAN_ID --tasks

# List buckets (columns) in a plan
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js planner --plan-id PLAN_ID --buckets

# Show one task's details (description, % complete, due date)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js planner --task-id TASK_ID

# Create a task in a plan (bucket, due date and assignee are optional)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js planner --plan-id PLAN_ID \
  --create "Write release notes" --bucket-id BUCKET_ID --due 2026-06-20 --assign USER_AAD_ID

# Mark a task complete (reads the etag, then sets it to 100%)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js planner --complete TASK_ID

# Machine-readable JSON output (on any read command)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js planner --my-tasks --json

--my-tasks returns only planId/bucketId (no names). To turn an ID into a readable plan name, run planner --plans. Use people --search NAME to get a user's AAD ID for --assign.

To Do

Personal Microsoft To Do task lists (simpler than Planner — flat lists of tasks).

# List your task lists
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js todo --lists

# List tasks in a list (use ID from --lists)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js todo --list-id LIST_ID --tasks

# Create a task
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js todo --list-id LIST_ID \
  --create "Renew certificate" --body "Before it expires" --due 2026-06-15

# Mark a task complete
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js todo --list-id LIST_ID --complete TASK_ID

Channels

# List channels in a team (use team ID from teams --teams-list)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js channels --team-id TEAM_ID --list

# Read recent messages in a channel
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js channels --team-id TEAM_ID --channel-id CHANNEL_ID --messages

# Read messages with their reply threads (needed to detect unanswered/clarification-only threads)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js channels --team-id TEAM_ID --channel-id CHANNEL_ID --messages --expand-replies --json

# Post a message to a channel
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js channels --team-id TEAM_ID --channel-id CHANNEL_ID --send "Hello channel!"

Transcripts

# List online meetings in a date range (defaults to last 7 days)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --start 2026-03-06

# List online meetings in a specific date range
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --start 2026-03-06 --end 2026-03-07

# Find meetings by subject keyword and show their transcripts
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --start 2026-03-06 --subject "standup"

# List transcripts for a known meeting ID
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --meeting MEETING_ID

# Read transcript content (plain text, printed to stdout)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --meeting MEETING_ID --transcript TRANSCRIPT_ID

# Save transcript to a file
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --meeting MEETING_ID --transcript TRANSCRIPT_ID --output meeting.txt

# Download as VTT (timestamped captions format)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --meeting MEETING_ID --transcript TRANSCRIPT_ID --vtt --output meeting.vtt

# AI meeting recap (Copilot-generated notes, action items, mentions) for a known meeting
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --meeting MEETING_ID --insights

# AI recap by date + subject (resolves the meeting for you)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js transcripts --start 2026-06-09 --subject "planning" --insights

AI Insights require a Microsoft 365 Copilot license. Insights are generated only after a meeting ends (with transcription/recording on) and can take up to 4 hours to appear. A 403 means the Copilot license is missing; an empty result means insights aren't ready yet.

People & Contacts

# Frequent collaborators (AI-ranked by Microsoft)
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js people

# Search people by name
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js people --search "Alice"

# Outlook address book contacts
node ${CLAUDE_PLUGIN_ROOT}/skills/msgraph/scripts/msgraph.js people --contacts

Workflow Patterns

"Show me my emails"

  1. Run status → check login
  2. Run emails --limit 15 → show results
  3. If user wants to read one, run emails --read ID

"What's on my calendar today/this week?"

  1. Run calendar --limit 10
  2. Parse dates in output and filter for user's timeframe

"Find a file in SharePoint"

  1. Run sharepoint --sites → list sites
  2. Run sharepoint --site SITE_ID → browse files
  3. Use --path to drill into folders
  4. Offer --download ITEM_ID if user wants the file

"Check my Teams messages"

  1. Run teams --chats → list chats
  2. User picks a chat → run teams --messages CHAT_ID

"Show me my OneNote notes" / "Find a note about X"

  1. Run onenote --notebooks → list notebooks
  2. Run onenote --sections NOTEBOOK_ID → list sections
  3. Run onenote --pages SECTION_ID → list pages, or use onenote --search "keyword" to search directly
  4. Run onenote --read PAGE_ID → display page content

"Show me the transcript from yesterday's standup"

  1. Run transcripts --start YYYY-MM-DD --subject "standup" → finds the meeting and lists transcript IDs
  2. Run transcripts --meeting MEETING_ID --transcript TRANSCRIPT_ID → reads full transcript text

"Get all meeting transcripts for today"

  1. Run transcripts --start YYYY-MM-DD → lists all online meetings for the day
  2. Run transcripts --meeting MEETING_ID → lists available transcripts per meeting
  3. Run transcripts --meeting MEETING_ID --transcript TRANSCRIPT_ID --output meeting.txt → saves each transcript

"Post a message to a Teams channel"

  1. Run teams --teams-list → get the team ID
  2. Run channels --team-id TEAM_ID --list → get the channel ID
  3. Run channels --team-id TEAM_ID --channel-id CHANNEL_ID --send "message"

"Who's my manager?" / "Who reports to me?"

  • Run org --manager or org --reports

"What are my tasks?" / "What's on my Planner?"

  1. Run planner --my-tasks → tasks assigned to you across all plans
  2. Run planner --plans to map any planId in the output to a readable plan name
  3. Drill in with planner --plan-id PLAN_ID --tasks if the user wants a specific board
  4. Also check todo --lists then todo --list-id LIST_ID --tasks for personal To Do items

"Add a task to Planner" / "Create a to-do"

  1. Planner: run planner --plans (then --buckets if a column is needed) to get IDs, then planner --plan-id PLAN_ID --create "TITLE" (add --due, --assign, --bucket-id as needed)
  2. To Do: run todo --lists, then todo --list-id LIST_ID --create "TITLE"

"Mark that task done"

  • Planner: planner --complete TASK_ID · To Do: todo --list-id LIST_ID --complete TASK_ID

"Summarize yesterday's meeting" / "What were the action items?"

  1. Run transcripts --start YYYY-MM-DD --subject "keyword" --insights (resolves the meeting and prints Copilot notes, action items, and mentions)
  2. Or, with a known meeting ID: transcripts --meeting MEETING_ID --insights
  3. If you get a 403, tell the user a Microsoft 365 Copilot license is required; if empty, insights may not be ready yet (up to 4 hours after the meeting ends)

Error Handling

Exit codeMeaning
0Success
1API error (shown in output)
2NOT_LOGGED_IN — user must run login

When you see Permission denied errors, it means the OAuth scope isn't granted for that operation. This can happen if the user's organization has restricted certain Graph API permissions.

Dependencies

None — the script uses only built-in Node.js modules (https, fs, path, os). Node.js >= 18 is required, which is already a CodeMie prerequisite. IMPORTANT: you must work with current date (get it from sh/bash)
