A [Model Context Protocol](https://modelcontextprotocol.io) server that connects Claude to [OurFamilyWizard](https://www.ourfamilywizard.com), giving you natural-language access to your co-parenting messages, calendar, expenses, and journal.

> [!WARNING]
> **AI-developed project.** This codebase was entirely built and is actively maintained by [Claude Sonnet 4.6](https://www.anthropic.com/claude). No human has audited the implementation. Review all code and tool permissions before use.

## What you can do

Ask Claude things like:

- *"Show me my recent OFW messages"*
- *"What's on the kids' calendar next week?"*
- *"List recent expenses and tell me what I owe"*
- *"Add a journal entry about today's pickup"*
- *"Draft a reply to the last message from my co-parent"*

## Requirements

- [Claude Desktop](https://claude.ai/download)
- [Node.js](https://nodejs.org) 22.5 or later (`node:sqlite` is the cache backend)
- An active OurFamilyWizard account

## Acknowledgement of Terms

By using this MCP server, you acknowledge and agree to the following:

**1. This server accesses your own OurFamilyWizard account.** Auth happens via your own credentials. It does not — and cannot — access your co-parent's account, your children's accounts, or anyone else's.

**2. [OurFamilyWizard's Terms](https://www.ourfamilywizard.com/legal/terms) govern your use of this server**, just as they govern your direct use of OFW. There is no explicit anti-scraping clause; the governing language is broader:

> Users may not obtain or attempt to obtain any materials or information through any means not intentionally made available.

And on credentials: *"You are solely responsible for (1) maintaining the strict confidentiality of assigned Authentication Methods, (2) instructing any individual to whom the assigned Authentication Method is shared ('Authorized User') to not allow another person to use the Authentication Method."* OFW does contemplate "Authorized Users" and third-party-enabled integrations — but the account holder remains responsible.

You are agreeing to those terms — read by the maintainer 2026-05-23 — every time you invoke a tool in this server.

**3. Personal, family use only.** This project is not affiliated with, endorsed by, sponsored by, or in partnership with OurFamilyWizard, LLC or its parent. It is a personal automation tool for the named account holder. Do not use it on behalf of a co-parent without their consent, do not share credentials with anyone, and do not use it to bulk-extract another family's data.

**4. OFW is a court-of-record platform.** Messages, expenses, calendar entries, and journal entries on OFW may be entered into legal proceedings — including custody, divorce, and parenting-plan-modification cases. Anything this server writes to OFW (drafts you save, events you create, expenses you log) will appear with the same legal weight as if you had typed it yourself. **Do not let this MCP send a message, create an event, or log an expense that you have not read and approved.** Review every write operation before confirming.

**5. You accept full responsibility** for any consequences — both technical (account warnings, suspension) and legal (anything OFW records about your account activity). The MCP author is not your attorney; if you're using OFW in connection with an active legal matter, talk to your actual attorney before automating anything.

This section is the maintainer's good-faith summary of the terms — it is not legal advice and does not modify or supersede OurFamilyWizard's actual ToS.

## Installation

### 1. Clone and build

```bash
git clone https://github.com/chrischall/ofw-mcp.git
cd ofw-mcp
npm install
npm run build
```

### 2. Add to Claude Desktop

Edit your Claude Desktop config file:

- **Mac:** `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows:** `%APPDATA%\Claude\claude_desktop_config.json`

Add the `ofw` entry inside `"mcpServers"` (create the key if it doesn't exist):

```json
{
  "mcpServers": {
    "ofw": {
      "command": "node",
      "args": ["/absolute/path/to/ofw-mcp/dist/index.js"],
      "env": {
        "OFW_USERNAME": "your-email@example.com",
        "OFW_PASSWORD": "your-ofw-password"
      }
    }
  }
}
```

Replace `/absolute/path/to/ofw-mcp` with the actual path where you cloned the repo. On Mac, run `pwd` inside the cloned directory to get it.

### 3. Restart Claude Desktop

Quit completely (Cmd+Q on Mac, not just close the window) and relaunch.

### 4. Verify

Ask Claude: *"What does my OFW dashboard look like?"* — it should show your unread message count, upcoming events, and outstanding expenses.

## Authentication

`ofw-mcp` tries three auth paths in order; whichever succeeds first is used. Existing setups keep working unchanged.

1. **Env-var credentials (legacy, recommended for Claude Desktop).** Set `OFW_USERNAME` + `OFW_PASSWORD` and the server logs in via OFW's form endpoint. This is the path shown in the Claude Desktop config above.
2. **fetchproxy fallback (no env vars needed).** When the credentials are absent, the server reads `localStorage["auth"]` once at startup from your already-signed-in `ourfamilywizard.com` tab via the [fetchproxy](https://github.com/chrischall/fetchproxy) browser extension. After that one read, all OFW API calls go directly from Node — the extension is **not** in the request hot path. Install the fetchproxy extension (Chrome Web Store / Safari `.dmg`), sign into OurFamilyWizard once, and the MCP just works. If you have multiple OFW accounts and want them to use separate caches, set `OFW_CACHE_IDENTITY` to a label per profile.
3. **Error.** If neither path is available, the server tells you exactly which fix to apply. Set `OFW_DISABLE_FETCHPROXY=1` to skip the fetchproxy fallback entirely (turns missing credentials into a hard error — useful in headless CI).

### Credential options (env-var path)

**Option A — env block in Claude Desktop config** (shown above, recommended):

```json
"env": {
  "OFW_USERNAME": "your-email@example.com",
  "OFW_PASSWORD": "your-ofw-password"
}
```

**Option B — `.env` file** in the project directory:

```bash
cp .env.example .env
# edit .env and fill in your credentials
```

Environment variables always take priority over the `.env` file. You can also pass them directly on the command line:

```bash
OFW_USERNAME=you@example.com OFW_PASSWORD=yourpass node dist/index.js
```

## Available tools

Read-only tools run automatically. Write tools ask for your confirmation first. The *Write mode* column shows the minimum `OFW_WRITE_MODE` a tool needs to be available at all — see [Write protection](#write-protection-ofw_write_mode) below.

| Tool | What it does | Permission | Write mode |
|------|-------------|------------|------------|
| `ofw_get_profile` | Your profile and co-parent info | Auto | any |
| `ofw_get_notifications` | Dashboard counts (unread messages, upcoming events, outstanding expenses) | Auto | any |
| `ofw_list_message_folders` | Folders with unread counts — **get folder IDs here before listing messages** | Auto | any |
| `ofw_list_messages` | Messages in a folder | Auto | any |
| `ofw_get_message` | Full content of a single message | Auto | any |
| `ofw_sync_messages` | Sync messages into the local cache (unread bodies left unfetched to avoid read receipts) | Auto | any |
| `ofw_get_unread_sent` | Sent messages a recipient hasn't read yet (from local cache) | Auto | any |
| `ofw_download_attachment` | Download a message attachment to disk (or inline as MCP content) | Auto | any |
| `ofw_send_message` | Send a message | Confirm | `all` |
| `ofw_list_drafts` | Draft messages | Auto | any |
| `ofw_save_draft` | Create or update a draft | Confirm | `drafts` |
| `ofw_delete_draft` | Delete a draft | Confirm | `drafts` |
| `ofw_upload_attachment` | Upload a local file to My Files; returns a fileId to attach via `ofw_send_message`/`ofw_save_draft` | Auto | `drafts` |
| `ofw_list_events` | Calendar events in a date range | Auto | any |
| `ofw_create_event` | Create a calendar event | Confirm | `all` |
| `ofw_update_event` | Update a calendar event | Confirm | `all` |
| `ofw_delete_event` | Delete a calendar event | Confirm | `all` |
| `ofw_get_expense_totals` | Expense summary totals | Auto | any |
| `ofw_list_expenses` | Expense history | Auto | any |
| `ofw_create_expense` | Log a new expense | Confirm | `all` |
| `ofw_list_journal_entries` | Journal entries | Auto | any |
| `ofw_create_journal_entry` | Create a journal entry | Confirm | `all` |

### Write protection (`OFW_WRITE_MODE`)

The "Confirm" permission above is a *hint* to the MCP host — a host configured to auto-approve tools (or a user who clicked "always allow" once) would leave nothing between model output and a sent message. Because OurFamilyWizard is a court-of-record platform, the server also supports a structural gate: set `OFW_WRITE_MODE` in the server's `env` block and tools above your chosen level are **never registered**, so no host setting or prompt-injected instruction can invoke them.

| `OFW_WRITE_MODE` | What's available |
|------------------|------------------|
| `none` | Read/sync/search only. No write tools exist. |
| `drafts` | Adds draft-level writes: `ofw_save_draft`, `ofw_delete_draft`, `ofw_upload_attachment`. Nothing that lands on the court-visible record — the AI prepares, only a human signed into the OFW web UI can send. |
| `all` | Everything (the default — fully backward compatible). |

Unrecognized values fail closed to `none`, with a warning on stderr — a typo never silently grants write access.
