OneDrive MCP server
Read the client folder you choose.
MegaMCP is a hosted OneDrive MCP server that lets Claude, ChatGPT and Cursor read files in one enabled client folder and propose file renames that you approve.
Rolling outBuilt, and switching on as approvals land.What this meansRolling out means the code is built and the platform is still approving MegaMCP's app: Google, Meta, Microsoft and the one-click ad-platform sign-ins switch on as each approval lands.

Watch it work on OneDrive
Ask in plain English. Your AI reads OneDrive with real MegaMCP tools, then hands you a plan. Nothing moves until a person clicks Approve, and supported changes can be undone.

What your AI can do
OneDrive MCP tools
Inspect, search and read supported text files inside one explicitly enabled Microsoft drive folder. This list comes straight from the running product: 4 read tools and 1 write tool.
4 tools
Changes you approve
Each one returns a plan with a diff. Nothing moves until a person approves.
- Reviewed file rename with ETag checks
- Supported conditional rename reversal
OneDrive guardrail
Live parent checks enforce the chosen folder. Renames use atomic ETag checks; reads can race a concurrent file move. Uploads and sharing controls are unavailable.
Plus complete diff previews, human approvals and the flight recorder on every connection. Live changes require a paid plan.

Example prompts
OneDrive MCP prompts
Paste any of these into Claude, ChatGPT or Cursor once OneDrive is connected.
“List this client folder's files.”
“Read this CSV's text.”
“Prepare a clearer file name for review.”
“Search the folder for files with 'invoice' in the name.”
“Inspect this file's size and last-modified date.”

“Read this CSV export and total the spend column.”
Setup
OneDrive MCP setup in 3 steps
About two minutes for Claude, ChatGPT or Cursor. Nothing to install.
Connect OneDrive
Start a free workspace and open Connections. Microsoft Graph uses a separate file authorization from Microsoft Ads. Delegated file grants are broad at Microsoft; MegaMCP restricts tools to enabled client folders.
Add MegaMCP to your AI app
Every app uses the same server URL.
MCP server URLhttps://megamcp.com/api/mcpAsk in plain English
Try “List this client folder's files.” Reports answer straight away. Anything that changes OneDrive comes back as a plan for you to approve.
Safety
Hand AI the keys. Keep the brakes.
The same loop guards every MegaMCP connection: ask, see the diff, approve, undo.
Approval before every change
OneDrive write tools never touch OneDrive directly. They return a plan, and a person approves it in the dashboard, or in chat if an admin allows it.

A diff first
Every plan lists each change with its before and after values, so you see exactly what will move before it does.

Undo for supported changes
Supported changes reverse through a separately reviewed undo plan. Anything that can't be undone is marked before you approve it.
Undo plan readyRestores the previous valuesReviewed like any other change
Receipts for everything
Platform checks stop stale edits, and the flight recorder logs every tool call, plan and approval, with who did it and from which AI app.

FAQ
OneDrive MCP server questions
Is there an official OneDrive MCP server?
Yes, with limits. As of October 2026, Microsoft offers SharePoint and OneDrive MCP servers through Agent 365, in preview for limited tenants. MegaMCP restricts tools to one enabled client folder and makes every rename a reviewed plan.
What is a OneDrive MCP server?
An MCP (Model Context Protocol) server lets AI assistants such as Claude, ChatGPT and Cursor use OneDrive through tools. MegaMCP's hosted OneDrive MCP server gives your assistant 4 read tools and 1 write tool for files in one enabled client folder, and every change waits for a human approval.
Does the OneDrive MCP server work with ChatGPT?
Yes. MegaMCP is a remote MCP server with OAuth sign-in, so one URL works in ChatGPT (as an app, with developer mode on), Claude (as a custom connector), Cursor, Claude Code and VS Code. Your AI app's own plan decides whether it can add custom MCP servers.
Can it make changes to my OneDrive account?
Yes, with your approval. It can propose file renames changes. Each one comes back as a plan with a line-by-line diff and waits for a human before anything moves. Live parent checks enforce the chosen folder. Renames use atomic ETag checks; reads can race a concurrent file move. Uploads and sharing controls are unavailable.
How do I connect OneDrive to Claude or ChatGPT?
Microsoft Graph uses a separate file authorization from Microsoft Ads. Delegated file grants are broad at Microsoft; MegaMCP restricts tools to enabled client folders. Operator app callback setup or a dedicated temporary token is required.
What does the OneDrive MCP server cost?
Reading OneDrive is free on MegaMCP's Free plan (100 reads a day, no card). Approved changes are included in every paid plan, from $19/month after a 5-day free trial, with unlimited runs and no credits. MegaMCP adds no markup: any subscription or API usage with the vendor stays between you and them.
Is my OneDrive data safe?
Your OneDrive credentials are encrypted at rest (AES-256-GCM) and bound to their connection, and MegaMCP never trains AI models on your data. Your AI only sees the accounts you switch on, members limited to certain clients only see those clients, and every tool call lands in the flight recorder.
