“The no-tokens part is huge. Setting up Graph API and dealing with auth flows is what usually kills these setups for me before I even start.”
Lisa S.“This is AMAZING! My daily work can all be managed from my key apps now. The OmniFocus integration was the missing piece.”

ChatGPT can work with OneDrive on your PC once LMCP is installed and added to ChatGPT. LMCP is a local MCP server: ChatGPT can browse, read, write, search and move files in the OneDrive folder synced on your PC, without the Graph API.
What ChatGPT Can Do with OneDrive
- Browse your OneDrive — list root folders and drill into any directory
- Read files and write & update files (synced back to the cloud)
- Search, move, rename and delete files across your OneDrive
- Scope access — restrict the AI to a single subfolder so it only sees what you allow
Preview and confirmation behavior depends on the tool, platform and AI client. Check the tool requirements and review the intended action before authorizing a real call.
What You Will Need
- A Windows PC with LMCP installed
- The OneDrive desktop app, signed in and syncing your files to the PC (usually under C:\Users\<you>\OneDrive)
- ChatGPT on the web in a desktop browser — MCP apps are added from Plugins; on Business/Enterprise/Edu a workspace admin may need to allow custom apps first

Install LMCP on your PC
Download LMCP for Windows from local-mcp.com and run — no admin rights needed. LMCP starts on its own, shows its icon in the system tray and configures your AI clients.
- 2
Turn on Cloud access and copy the URL
Click the LMCP icon in the system tray (it can be behind the ^ arrow next to the clock) and find Web AI clients. Make sure Cloud access is on, then click Copy URL.
The URL is — it carries no token and is the same for everyone; every step below that says “the URL you copied” means this one. Access is granted by approving the connection on your PC, not by the URL. - 3
Open Plugins
Use a desktop browser at chatgpt.com — MCP apps can’t be added from the mobile or desktop apps. Click Plugins in the sidebar (or go to chatgpt.com/plugins). There is no Developer mode to turn on any more; on Business/Enterprise/Edu a workspace admin may need to allow custom apps first.

Create the MCP App
Click Add ▾ at the top right and choose Create MCP App — not “Create plugin”. In the New Plugin dialog set Name: , leave Connection on Server URL and paste the URL you copied from the LMCP tray icon (). Authentication stays on “OAuth” — leave Advanced OAuth settings empty, we auto-register. Tick I understand and want to continue (Create stays disabled until you do) and click Create.

Sign in and approve on your PC
Create only registers the connector — it still reads “No app actions available yet”. Click Sign in with LMCP: ChatGPT opens an Authorize page on , and a dialog appears on your PC. Click Approve there and the tool catalog loads.
If no dialog shows up, or the page says LMCP isn’t running, the approval request simply expired. Click the button again; nothing needs reinstalling. - 6
Enable it in a chat
Start a new conversation and enable LMCP from the composer’s tools menu (+). Then ask: “List my email accounts” or “What meetings do I have today?”
In Settings → Plugins, Default permission decides which tools run without asking: with Allow low-risk tools, tools ChatGPT considers low-risk can run without a prompt, and the rest still ask first.
Steps verified 2026-09-27. Local tools run on your device; selected AI providers and connectors receive requested content. Review each tool’s permissions and approval behavior.

Try It Out
Start a new chat, enable LMCP via + → More → LMCP, then ask:
Only give yourself access to my “Work Documents” folder in OneDrive, nothing else.
Find the budget spreadsheet in my OneDrive.
Save these meeting notes as a file in my OneDrive.
Troubleshooting
A file cannot be read
With Files On-Demand, online-only files download when they are opened; files you keep explicitly online-only need to be available on the PC first. The web-only OneDrive does not create a local folder LMCP can read.
The connector shows “No app actions available yet”
Normal — that panel doesn’t list tools. Enable LMCP in a chat via + → More → LMCP and it works.
ChatGPT says it cannot reach your computer
LMCP is not running, or Cloud access is off. Click the LMCP icon in the system tray and check, under Web AI clients, that Cloud access is on. If LMCP is not running at all, download and reinstall it.
ChatGPT says “the connector is not authenticated”
The approval is no longer valid. Click Sign in with LMCP again and approve in the dialog that opens on your PC. The connector URL stays the same, so there is nothing to copy or add again.
