# How to connect Microsoft OneDrive to Hermes Agent (no Azure app registration)

> Connect Microsoft OneDrive to Hermes Agent with ClawLink: no Azure app registration, no client secret, no admin consent to chase. 60 OneDrive tools your agent calls from chat.

Web version: https://claw-link.dev/hermes/onedrive

Most guides for giving Hermes Agent Microsoft OneDrive access start with registering your own OAuth app or pasting API keys into env files, then leave the token refresh and tool wiring to you. ClawLink gives Hermes a more practical Microsoft OneDrive setup: pair once in the browser and your always-on Hermes agent can act on Microsoft OneDrive for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself.

**Start here — paste this into Hermes to set up ClawLink:**

> Set up ClawLink for Hermes and tell me when it's ready.
> 1. Install the plugin: `hermes plugins install ClawLink-HQ/hermes-plugin --enable`
> 2. Start pairing with `hermes clawlink begin`. It prints an approval link, so show me the link and stop, don't wait.
> 3. I'll approve it in my browser, then reply "approved".
> 4. When I say approved, finish setup: `hermes clawlink finish`
> 5. Then run `hermes clawlink test` and tell me whether ClawLink is ready.

## Setup

It takes three steps to connect Hermes to Microsoft OneDrive.

1. **Install ClawLink** — add the plugin to Hermes Agent once.
2. **Connect Microsoft OneDrive** — one-click OAuth in the ClawLink dashboard.
3. **Use it from chat** — ask Hermes Agent in plain English.

**Alternative for any agent (no plugin needed):** if the Hermes Agent plugin route isn't available or doesn't work, any AI agent with shell access can use the ClawLink CLI instead:

```bash
npx -y @useclawlink/cli login          # sign in via browser — no API key to paste
npx -y @useclawlink/cli connect onedrive  # connect Microsoft OneDrive (browser OAuth)
npx -y @useclawlink/cli actions onedrive  # list available actions
npx -y @useclawlink/cli run onedrive <action> --input '<json>'  # execute (add --confirm for writes)
```

### Install by command

The prompt above walks Hermes through this. By hand, it is four commands and a browser approval:

```bash
hermes plugins install ClawLink-HQ/hermes-plugin --enable
hermes clawlink begin    # prints an approval link — open it and approve
hermes clawlink finish   # after approving in the browser
hermes clawlink test
```

Then connect Microsoft OneDrive in the [ClawLink dashboard](https://claw-link.dev/dashboard) — a one-click OAuth approval, no API keys.

Verify the connection by asking Hermes:

> Use one_drive_search_items to find files mentioning "renewal forecast" in my OneDrive. Show me the name, folder path, and last modified date for each, and tell me which one is most recent.

### Using a different agent?

The Hermes plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI:

```bash
npx -y @useclawlink/cli login
```

`login` opens the same browser approval and stores a credential locally. Once Microsoft OneDrive is connected in the dashboard, that agent calls the same 60 Microsoft OneDrive tools over MCP. Full setup for MCP clients and shell agents: [connect apps to any AI agent](https://claw-link.dev/learn/connect-apps-to-any-ai-agent).

## Microsoft OneDrive MCP for Hermes

Looking for a Microsoft OneDrive MCP server for Hermes Agent? ClawLink connects Microsoft OneDrive to Hermes Agent and exposes 60 Microsoft OneDrive tools your agent can call over [MCP](https://claw-link.dev/learn/what-is-an-mcp-server), with [hosted auth](https://claw-link.dev/learn/oauth-for-ai-agents) and nothing to run or maintain yourself. Using OpenClaw instead? The [OpenClaw Microsoft OneDrive integration](https://claw-link.dev/openclaw/onedrive) works the same way.

Microsoft now ships its own no-code agents for OneDrive, so "no API key" on its own is no longer a distinguishing promise. The distinction that still holds is where the work happens. Copilot's agents live inside Microsoft 365 and answer inside Microsoft's surfaces; building your own means registering an application in Entra ID, requesting Files.ReadWrite, chasing admin consent, and managing a client secret that expires. ClawLink connects through Microsoft's sign-in with an application that is already registered, and puts the 60 tools below inside Hermes chat, next to whatever else your agent is doing. The access is delegated, so the agent reaches exactly the files your account reaches and nothing beyond them.

## What the Hermes Agent Microsoft OneDrive integration can do

60 Microsoft OneDrive tools are ready for Hermes Agent once the account is connected. The 30 below are the ones people reach for most; your agent can call all 60.

**Clean up a folder**

> List everything in my Documents folder with one_drive_list_folder_children, including sizes and last modified dates. Tell me which files are over 100 MB or untouched for more than a year. Do not delete anything, just give me the list.

**Share a file with a colleague**

> Find the file called "Q3 board deck" with one_drive_onedrive_find_file, show me who currently has access using one_drive_list_share_permissions, then create a view-only link with one_drive_create_link. Confirm the file and the permission level with me before you create it.

**Save a summary back to OneDrive**

> Read the contents of the file I name, write a one-page summary, and save it as "Summary - board deck.txt" in the same folder using one_drive_onedrive_create_text_file. Tell me the path when it exists.

## How the OneDrive tools behave

Argument-level detail from the manifest. The first two save the most wasted calls.

- **Item ids are opaque and cannot be guessed.** `one_drive_search_items`, `one_drive_onedrive_find_file`, and `one_drive_list_folder_children` are the discovery calls. Everything that reads, moves, or shares takes an id from one of them.
- **Search beats walking the tree.** `one_drive_search_items` finds a file across the drive in one call. Repeated `one_drive_list_folder_children` calls down a deep hierarchy is what triggers the throttling described above.
- **Sharing has four distinct tools.** `one_drive_create_link` makes a link, `one_drive_invite_user_to_item` invites a person, `one_drive_grant_share_permission` grants against an existing share, and `one_drive_list_share_permissions` shows what is already in place. "Share this file" spans at least two of them, so name the one you want.
- **Version history is reachable.** `one_drive_get_item_versions`, `one_drive_download_item_version`, and `one_drive_restore_drive_item_version` let an agent recover an earlier copy without you opening the web app.
- **Deletion has two levels.** `one_drive_delete_item` is recoverable through `one_drive_restore_drive_item`; `one_drive_delete_item_permanently` is not.
- **Format conversion exists.** `one_drive_download_item_as_format` converts on the way out, which is the shortest route from a Word document to a PDF without opening anything.
- **Some tools reach SharePoint.** `one_drive_get_site`, `one_drive_list_site_lists`, and `one_drive_get_sharepoint_list_items` cross into SharePoint sites, because Microsoft stores both on the same Graph endpoints. For real SharePoint work, the [Hermes SharePoint integration](https://claw-link.dev/hermes/sharepoint) has 86 tools aimed at it.

## ClawLink vs. building it yourself

The alternative to ClawLink is usually manual OAuth app setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Microsoft OneDrive working from chat.

| | Manual | ClawLink |
|---|---|---|
| **Connection flow** | Register a Microsoft OneDrive app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Microsoft OneDrive through the hosted browser flow and ClawLink keeps the token lifecycle out of your app code. |
| **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Microsoft OneDrive. | ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure. |
| **Agent usability** | You still need to expose the right Microsoft OneDrive actions to the runtime in a format your agent can reliably use. | 60 tools for Microsoft OneDrive are already exposed through ClawLink, so the agent can read and act from chat immediately. |

## ClawLink vs. Composio

Composio also exposes Microsoft OneDrive to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for Hermes Agent users instead. You install the plugin once, connect Microsoft OneDrive in the browser, and the 60 tools above work from chat. There is no SDK, no config file, and no API key handling. Choosing between them? Read the full [Composio alternatives](https://claw-link.dev/hub/composio-alternatives) comparison.

### Hermes paired but still can't use Microsoft OneDrive
Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`. If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link. Confirm the plugin was installed with `--enable`, then verify with `hermes clawlink test`.

### Connection succeeds but no tools appear
Reconnect Microsoft OneDrive from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded.

### "Tool schema not loaded yet" error when calling Microsoft OneDrive tools
Microsoft OneDrive tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every Microsoft OneDrive call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again.

### Microsoft OneDrive returns 403 or "permission denied" on one action while others work
Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs.

### OneDrive returns 403 "accessDenied" or Microsoft Graph returns "Authorization_RequestDenied"
Search results answer this by sending you to the Azure Portal to add Files.ReadWrite.All, grant admin consent, and inspect your token at jwt.ms. None of that applies here, because the permissions were fixed at sign-in and there is no token for you to decode. Two causes account for it instead. The first is real access: the connection acts as you, so a file or folder you cannot open in the OneDrive web app is not reachable from chat either, and files shared with you can have their sharing revoked without warning. The second is a placeholder argument: item ids in OneDrive are opaque strings, and an agent that has not listed anything yet will invent one, which reaches Microsoft and returns a permissions-shaped error rather than a bad-argument error. Ask for one_drive_list_folder_children or one_drive_search_items first, then retry with a real id.

Ask the agent to diagnose it:

```text
Run one_drive_get_drive and tell me which account and drive you are connected to. Then run one_drive_list_folder_children on the root and show me what you can see. Do not retry the failing call until both have returned.
```

### OneDrive returns 507 "insufficientStorage" or 429 with a Retry-After header
These look similar in chat and mean different things. A 507 is storage: the drive is full, and OneDrive counts items in the online recycle bin against your quota, so emptying it in the web app frees space that deleting files alone did not. A 429 is throttling: Microsoft Graph is rate-limiting the requests and the response carries a Retry-After value telling you how long to wait. Retrying a 429 immediately makes it worse, and reconnecting does nothing for either. If an agent is walking a large folder tree, the practical fix is to narrow the work: search for what you need with one_drive_search_items instead of enumerating everything with repeated one_drive_list_folder_children calls.

Ask the agent to diagnose it:

```text
Report the exact status code and any Retry-After header from the failed OneDrive call. Do not retry it.
```

### A OneDrive tool returns "tool not found" on a working connection
Tool schemas load on demand, so the first OneDrive call in a fresh session can arrive before the catalog is available. Retry once. If the same name fails twice, the name is wrong rather than missing, and the error lists the closest real tools. Note that several tools in this integration carry a doubled prefix by design, including one_drive_onedrive_upload_file and one_drive_onedrive_create_folder, so a name that looks like a mistake may be correct. The failures described in most search results, where an MCP server fails to initialize or an IDE needs restarting, do not apply here; there is no local server and no config JSON.

Ask the agent to diagnose it:

```text
List the OneDrive tools you actually have available and tell me which one uploads a file. Use that exact name.
```

### OAuth finished in the browser but the account is still missing
Try reconnecting Microsoft OneDrive and complete the consent flow in the same browser session. Partial OAuth approvals or switching accounts mid-flow can leave the connection incomplete.

### Is there a Hermes Agent Microsoft OneDrive integration?
Yes. ClawLink is the fastest way to connect Hermes to Microsoft OneDrive: link your Microsoft OneDrive account once in the browser and Hermes Agent can call the Microsoft OneDrive API through 60 ready-made tools — no custom code or token handling.

### How do I connect Microsoft OneDrive to Hermes with ClawLink?
Install the plugin with `hermes plugins install ClawLink-HQ/hermes-plugin --enable`, then pair once: run `hermes clawlink begin`, approve the link in your browser, and run `hermes clawlink finish`. Connect Microsoft OneDrive in the dashboard and Hermes can use it from the next message — no config files or API keys to manage.

### How long does it take to connect Microsoft OneDrive to Hermes Agent?
About two minutes. Sign in, click Connect next to Microsoft OneDrive in the dashboard, authenticate, and Hermes Agent can use it from the next chat message.

### Why use ClawLink instead of wiring Microsoft OneDrive up myself?
The alternative to ClawLink is usually manual OAuth app setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Microsoft OneDrive working from chat.

### Can I connect OneDrive to an AI agent without an Azure app registration?
Yes. The registration step belongs to building the integration yourself: create an application in Entra ID, add Microsoft Graph permissions, get consent, then rotate a secret before it expires. ClawLink connects through an application that is already registered, so your part is a Microsoft sign-in. The access is delegated rather than application-level, which means the agent acts as you and inherits your permissions instead of holding tenant-wide reach of its own. If your organization routes new applications through an approval queue, an administrator approves it once and everyone in the tenant is covered.

### How is this different from Microsoft's own OneDrive agents?
Microsoft's agents run inside Microsoft 365 and are configured there, which is the right answer when the work starts and ends in OneDrive and everyone involved has the relevant Copilot licensing. This connection puts OneDrive tools into Hermes, so a single prompt can pull a spreadsheet from OneDrive, cross-reference something from another connected service, and write a summary somewhere else. The practical question is whether your workflow is OneDrive-shaped or agent-shaped. If the agent only ever touches OneDrive, Microsoft's own tooling is worth a look first.

### Can the agent see files shared with me, or only my own?
Both, because the connection acts as your account and your account sees both. one_drive_get_shared_items lists what other people have shared with you, and one_drive_get_drive_item_by_sharing_url opens a specific file from a sharing link someone sent you. Anything nobody shared with you stays out of reach, which is the same boundary you experience in the OneDrive web app.

### Can it share files with other people?
Yes, and this is the group of tools worth being deliberate about. one_drive_create_link generates a sharing link, one_drive_invite_user_to_item sends an invitation, and one_drive_grant_share_permission and one_drive_update_drive_items_permissions change who can reach what. A sharing link created without thought is a file handed to whoever holds the URL, so keep an approval step in the prompt before the agent shares anything, and use one_drive_list_share_permissions to review what already exists.

### Hermes paired but still can't use Microsoft OneDrive
Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`. If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link. Confirm the plugin was installed with `--enable`, then verify with `hermes clawlink test`.
