Microsoft 365 v3

QUILR FLAGSHIP MCP

One Microsoft 365 brain. Not four disconnected connectors.

Mail, calendars, files, SharePoint, Teams, people, OneNote, search, sync, and controlled actions through one governed MCP.

9 workloads1 connectionRead + write workflows

Provider-native

Choose native connectors for retrieval

Use first-party Microsoft APIs or approved product connectors when the job is primarily searching and reading one workload inside a supported client.

• Focused retrieval context
• Provider-native authorization model

Quilr-managed

Choose one operational Microsoft surface

Use Quilr when an agent must safely move from search to action across mail, calendars, files, SharePoint, Teams, people, OneNote, and sync.

• Nine workloads through one connection
• Writes, batch, sync, and destructive controls

Decision signalRetrieval-only use cases can stay native. Cross-workload operational agents benefit from the unified Quilr surface.

The difference: ChatGPT's documented Outlook and SharePoint connector tools are excellent for retrieval. Quilr Microsoft 365 v3 is an operational MCP for end-to-end work across Microsoft 365.

Comparison scope

The ChatGPT columns reflect the Outlook Email, Outlook Calendar, and SharePoint tools in OpenAI's current connector tool catalog. Newer ChatGPT workspace agents can have additional administrator-configured connector actions. Exact availability depends on product surface, workspace policy, OAuth scopes, and rollout.

Outlook Mail	Search, list, batch-read, attachments, folders	Draft, send, reply, forward, move, mark read, delete
Calendar	Calendars, events, attachments, schedules, free/busy	Create, update, respond, cancel, attach files
OneDrive	Search, list, metadata, content, changes	Upload, resumable upload, copy, move, share, delete
SharePoint	Sites, drives, lists, items, files, URL resolution	Create/update lists and files, upload, move, delete
Teams	Chats, channels, messages, replies, meetings, presence	Send messages, reply, create/update/delete meetings
Directory	Profiles, relevant people, manager, reports, org chain	Read-only by design
OneNote	Notebooks, section groups, sections, pages	Create and update notebooks, sections, and pages
Microsoft Search	Search across mail, files, events, and people	Returns recommended next tool calls
Synchronization	Delta cursors for email, calendar, and drive changes	Incremental processing without full re-reads

Built For Enterprise Control

• Every operation is labeled read, write, idempotent write, or destructive.
• Large attachments and files use bounded or resumable transfer flows.
• Batch tools reduce agent round trips while enforcing per-call limits.
• Capability tokens protect download and continuation URLs.
• Microsoft delegated OAuth preserves the connected user's permissions.
• MCP Gateway can apply tool allowlists, sensitive-data scanning, agent access rules, and audit logging.
