Häufige Fragen
Ist Outlook Mac MCP sicher?
Er hat 1 von 1 zutreffenden Basischecks bestanden. Den Code haben wir nicht gelesen. Bevor du einen Schlüssel oder Token hinzufügst, sieh nach, welche Zugriffe der Server verlangt, und nutze einen Schlüssel, der nur die Berechtigungen hat, die du brauchst.
Welche Schlüssel oder Codes braucht er?
Die Registry nennt keinen erforderlichen Schlüssel, manche Server bitten dich aber bei der ersten Nutzung, dich anzumelden.
Läuft er auf meinem Computer oder in der Cloud?
Er läuft auf deinem Computer. Deine KI-App startet ihn bei Bedarf, und die Daten laufen nicht über die Server des Entwicklers (außer der Server ruft selbst einen Onlinedienst auf).
Wird er noch gepflegt?
Das GitHub-Repo wurde zuletzt – geändert, und die neueste Version (0.9.0) kam vor 2 Monaten in die Registry.
Welche Apps können ihn nutzen?
Apps, die MCP unterstützen, etwa Claude Desktop, Claude Code, Cursor und VS Code.

outlook-mac-mcp
MCP server for Microsoft Outlook, built for personal Microsoft accounts (Hotmail, Outlook.com, Live) that run on the consumer infrastructure rather than Exchange Online — and are therefore not supported by the official "Claude for Outlook" add-in nor by the Microsoft 365 connector.
Backend: Microsoft Graph API with delegated, user-consented, least-privilege scopes. Python, transport stdio, no telemetry.
Why not AppleScript
Community MCP servers for Outlook on Mac drive the app through AppleScript. That path only works with Legacy Outlook. In August 2026 Microsoft cancelled the planned AppleScript support in New Outlook, and the transition to New Outlook ends in October 2026. This project deliberately does not depend on it.
The reference environment for this project runs New Outlook (the "Legacy Outlook" toggle is present in the Outlook menu), where AppleScript automation is unavailable. This was the deciding factor.
Technical requirements
Runtime
| Component | Requirement | Notes |
|---|---|---|
| macOS | 13 Ventura or later | Keychain used for token storage |
| Python | 3.12+ | Managed with uv; dependencies pinned in uv.lock |
| MCP client | Any stdio client (Claude Desktop, Claude Code) | Tested against Claude Desktop |
| Network | HTTPS to login.microsoftonline.com and graph.microsoft.com only | No other outbound calls |
Microsoft account and app registration
| Item | Requirement |
|---|---|
| Account type | Personal Microsoft account (Hotmail / Outlook.com / Live) or work/school |
| App registration | One-time registration in Microsoft Entra ID (free; a personal account needs its own tenant, created via the Azure Portal) |
| Supported account types | "Accounts in any organizational directory and personal Microsoft accounts" |
| Authentication | Device-code flow (MSAL, public client, no client secret) |
| Authority | https://login.microsoftonline.com/consumers |
| Scopes requested by default | Mail.Read, Calendars.Read, Contacts.Read, offline_access, User.Read |
Scope added by OUTLOOK_MCP_ENABLE_CALENDAR_WRITE=true | Calendars.ReadWrite (see Optional: calendar write) |
| Admin consent | Not required — every scope above is user-consentable |
offline_access, openid and profile are reserved scopes: MSAL appends them to every request on its own and raises if they are passed explicitly. They are consented at the registration but never appear in the list the code asks for — that consent is what yields the refresh token behind the Keychain cache.
The app registration may list broader permissions than the server requests. The token only ever carries the scopes the running configuration asks for: the write scope is requested only behind a config flag that is off by default, and turning it on triggers a new sign-in and consent prompt.
Not required
- Microsoft Outlook desktop app (the server talks to Graph, not to the app)
- Exchange Online / Microsoft 365 business tenant
- Accessibility or Automation permissions on macOS
- Node.js, Bun, or any non-Python runtime
Validated environments
Ordered chronologically by validation date (oldest first).
| Version | OS | Python | MCP client | Account type | Outlook app installed | Status |
|---|---|---|---|---|---|---|
| 0.1.0 | macOS 27.0 (Golden Gate), Apple M5 | 3.14.7 | Claude Desktop | Personal (@hotmail.com) | Outlook for Mac 16.112.4 (26090911), New Outlook, M365 Subscription — not used by the server | validated 2026-09-14 |
| 0.2.0 (calendar write on) | macOS 27.0 (Golden Gate), Apple M5 | 3.14.7 | Claude Desktop | Personal (@hotmail.com) | as above | validated 2026-09-15 |
| 0.9.0 (through delete_event) | macOS 27.0 (Golden Gate), Apple M5 | 3.14.7 | Claude Desktop | Personal (@hotmail.com) | as above | validated 2026-09-17 |
A row moves to validated only after the tools it names return correct results on that environment, against a real mailbox. Contributions of new rows are welcome — please include exact versions.
Validated tools
Sorted alphabetically by tool name. One shipped tool is not in this table yet — it has unit and respx coverage but no live validation against a real mailbox:
search_contacts— no contact exists in the test mailbox to search for yet.
| Tool | Validated | What was checked |
|---|---|---|
count_emails | 2026-09-15 | A received-time range covering one month returned an exact count. |
create_event | 2026-09-15, 2026-09-16, 2026-09-17 | Created a timed event and an all-day event; Graph accepted the all-day payload with the resolved zone's name, and both came back readable. A body from the preview was written to the created event correctly. An event with no body at all also succeeded, confirming the fix for Graph defaulting an unsent body to HTML. |
delete_event | 2026-09-17 | Deleted the event previewed under preview_event_deletion's token; confirmed removed from the calendar directly in Outlook. |
get_email | 2026-09-14 | Text body returned with the Prefer header honoured; the malformed id nope came back as ErrorInvalidIdMalformed and was mapped to InvalidRequestError. |
list_emails | 2026-09-15 | sort=oldest, limit=1 returned the folder's earliest email with an exact total; an exact-sender filter with sort=newest returned exactly one match, and Graph accepted the sender filter combined with $orderby without an InefficientFilter error. |
list_folders | 2026-09-17 | Discovered 100+ custom folders correctly, including several levels of nesting, each with accurate per-folder unread/total counts. Confirmed the documented limitation live: a Microsoft-managed folder with no well-known flag (Deleted Items) appeared in custom as expected, alongside genuine user-created folders. |
list_largest_emails | 2026-09-16 | Returned ranked results with real sizes from the extended property, skipped near zero. |
list_todays_events | 2026-09-15 | Returned zero events, exact, on a free day. |
list_unread_emails | 2026-09-14 | Reads a Hotmail inbox through Graph. |
list_upcoming_events | 2026-09-15 | Returned the matching events, earliest first; confirmed both an all-day event and a timed event mapped correctly in the resolved time zone. |
preview_event | 2026-09-15, 2026-09-16 | Summary and token for a timed and an all-day event; a body well under the truncation threshold showed in full, verbatim, in the preview. |
preview_event_deletion | 2026-09-17 | Showed the complete event (every field, unabbreviated) with the irreversibility warning before any deletion happened. |
preview_event_update | 2026-09-17 | A time change (10:00–10:30 -> 11:00–11:30) produced a diff summary showing only the changed field, old value -> new value. |
search_emails | 2026-09-14, 2026-09-15, 2026-09-17 | A term matching several emails returned an exact total; scope=subject and scope=sender each returned a narrower, still-exact subset; a term trying to break out of the phrase returned empty with no 400. Passing next_page_token back as page_token returned a genuinely different second page (a different date window, no items repeated from the first), with total/total_is_exact still accurate on that page. |
top_senders | 2026-09-15 | A full inbox scan hit the configured ceiling with coverage_is_complete=false; the client reported the partial coverage explicitly, as the description asks. |
update_event | 2026-09-17 | Applied the previewed time change (10:00–10:30 -> 11:00–11:30) exactly; the updated event reflected only that change. |
Every tool below has been validated against a real mailbox on the environment above; search_contacts has unit and respx coverage but no live validation yet (see above). Search quoting is additionally covered by a live positive-control check, see Integration tests.
Scope
- v1 (read-only): unread emails, emails by folder (well-known or custom, by full path), search by term, read one email by id (body included), list folders, today's / upcoming events, contact search.
- v2: create and update calendar events — behind a config flag, off by default; delete calendar events — behind a second flag, off by default even when the first one is on; mark as read — not yet built.
- v3: send email — behind a config flag, off by default, with explicit per-call confirmation.
Tools
Read tools are always registered. The four tools marked v2, flagged register only when OUTLOOK_MCP_ENABLE_CALENDAR_WRITE=true (see Optional: calendar write). preview_event_deletion and delete_event, marked v2, flagged + calendar delete, additionally need OUTLOOK_MCP_ENABLE_CALENDAR_DELETE=true (see Optional: calendar delete). Sorted alphabetically by tool name.
| Tool | What it does |
|---|---|
count_emails | Count emails matching the same filters as list_emails, exactly, without listing them. |
create_event (v2, flagged) | Create the event previewed under a token from preview_event. |
delete_event (v2, flagged + calendar delete) | Delete the event previewed under a token from preview_event_deletion. Irreversible. |
get_email | Fetch one email by id, body included. |
list_emails | List emails in a folder with any combination of filters (read state, sender, date range, attachments), sorted newest or oldest, with an exact total. |
list_folders | List the mailbox's well-known folders with their unread and total item counts, plus every user-created folder found by walking the mailbox tree, each identified by its full path. |
list_largest_emails | List a folder's largest emails by byte size, largest first, scanning up to 10,000 matching emails per call; emails with no determinable size are counted separately in skipped. |
list_todays_events | List today's calendar events, earliest first. |
list_unread_emails | List unread emails in a folder, newest first. |
list_upcoming_events | List calendar events from now through 1–30 days ahead. |
preview_event (v2, flagged) | Validate a new event and return a token and a summary, without creating it. |
preview_event_deletion (v2, flagged + calendar delete) | Fetch an existing event and return a token and a summary showing every field, unabbreviated, without deleting anything. |
preview_event_update (v2, flagged) | Fetch an existing event, validate the requested changes, and return a token and a diff summary (old value -> new value, changed fields only), without applying anything. |
search_contacts | Search contacts by a display-name prefix or an exact email address. |
search_emails | Search a folder for a term, ranked by relevance, not by date. |
top_senders | Rank a folder's senders by how many emails each sent, scanning up to 10,000 matching emails per call. |
update_event (v2, flagged) | Apply the change previewed under a token from preview_event_update. Only the fields actually passed to the preview are changed. |
Custom folders
A custom folder is any folder the user created in Outlook — not one of the five well-known folders (inbox, archive, junk email, sent items, drafts). search_emails, list_emails, count_emails, top_senders, list_largest_emails and list_unread_emails all accept one of the following as their folder argument:
- A well-known folder by name, matched case-insensitively —
folder="inbox",folder="INBOX"andfolder="Archive"all resolve the same way. - `all` — every well-known folder, merged. Custom folders are never included, however many exist:
folder="all". - A custom folder by its full path, exactly as
list_foldersreports it undercustom(folder names repeat across a mailbox; the full path is what disambiguates them): `fo
