# How to connect Microsoft To Do to Hermes Agent (no API keys)

> Connect Microsoft To Do to Hermes with ClawLink in one click — 22 tools your AI agent can call from chat via hosted OAuth. No API keys, no manual setup.

Web version: https://claw-link.dev/hermes/microsoft-todo

Most guides for giving Hermes Agent Microsoft To Do 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 To Do setup: pair once in the browser and your always-on Hermes agent can act on Microsoft To Do for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself.

## Setup

It takes three steps to connect Hermes to Microsoft To Do.

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

**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.

**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 microsoft-todo  # connect Microsoft To Do (browser OAuth)
npx -y @useclawlink/cli actions microsoft-todo  # list available actions
npx -y @useclawlink/cli run microsoft-todo <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 To Do in the [ClawLink dashboard](https://claw-link.dev/dashboard) — a one-click OAuth approval, no API keys.

Verify the connection by asking Hermes:

> List my Microsoft To Do task lists and the open tasks in each one.

### 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 To Do is connected in the dashboard, that agent calls the same 22 Microsoft To Do tools over MCP.

## 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 To Do working from chat.

| | Manual | ClawLink |
|---|---|---|
| **Connection flow** | Register a Microsoft To Do app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Microsoft To Do 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 To Do. | 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 To Do actions to the runtime in a format your agent can reliably use. | 22 tools for Microsoft To Do are already exposed through ClawLink, so the agent can read and act from chat immediately. |

## ClawLink vs. Composio

Composio also exposes Microsoft To Do 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 To Do in the browser, and the 22 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 To Do
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 To Do 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 To Do tools
Microsoft To Do 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 To Do 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 To Do 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.

### Need admin approval
Your work or school Microsoft account blocks you from approving new apps yourself. ClawLink's Microsoft app is not publisher-verified yet, and many organizations only let an IT admin approve apps like that. Ask your IT admin to approve ClawLink once for the organization. Personal Microsoft accounts (Outlook.com, Hotmail, Live) do not see this screen.

### OAuth finished in the browser but the account is still missing
Try reconnecting Microsoft To Do 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 To Do integration?
Yes. ClawLink is the fastest way to connect Hermes to Microsoft To Do: link your Microsoft To Do account once in the browser and Hermes Agent can call the Microsoft To Do API through 22 ready-made tools — no custom code or token handling.

### How do I connect Microsoft To Do 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 To Do 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 To Do to Hermes Agent?
About two minutes. Sign in, click Connect next to Microsoft To Do in the dashboard, authenticate, and Hermes Agent can use it from the next chat message.

### Why use ClawLink instead of wiring Microsoft To Do 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 To Do working from chat.

### Hermes paired but still can't use Microsoft To Do
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`.
