# splitwise-mcp

MCP server for Splitwise — natural-language expense and group management via the Splitwise API.

- **npm:** [npmjs.com/package/splitwise-mcp](https://www.npmjs.com/package/splitwise-mcp)
- **Source:** [github.com/chrischall/splitwise-mcp](https://github.com/chrischall/splitwise-mcp)

## Setup

### Option A — npx (recommended)

Add to `.mcp.json` in your project or `~/.claude/mcp.json`:

```json
{
  "mcpServers": {
    "splitwise": {
      "command": "npx",
      "args": ["-y", "splitwise-mcp"],
      "env": {
        "SPLITWISE_API_KEY": "your-api-key-here"
      }
    }
  }
}
```

### Option B — from source

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

Then add to `.mcp.json`:

```json
{
  "mcpServers": {
    "splitwise": {
      "command": "node",
      "args": ["/path/to/splitwise-mcp/dist/index.js"],
      "env": {
        "SPLITWISE_API_KEY": "your-api-key-here"
      }
    }
  }
}
```

Or use a `.env` file in the project directory with `SPLITWISE_API_KEY=<value>`.

### Getting your API key

1. Go to [splitwise.com/apps/register](https://secure.splitwise.com/apps/register)
2. Register an app (name and description can be anything)
3. Copy the **API key** from the app detail page

## Authentication

API key auth — no login flow or token rotation. The key is attached to every request as `Authorization: Bearer <key>`.

## Tools

### User
| Tool | Description |
|------|-------------|
| `sw_get_current_user(view?)` | Get the authenticated user's profile. On the default `compact` rung that is `id`, `name` (first + last joined), `email`, `registration_status`, `balance`; `first_name` / `last_name` separately are on `view: "full"` |

### Groups
| Tool | Description |
|------|-------------|
| `sw_list_groups(view?)` | List all groups with `id`, `name`, `group_type`, `members[]`, `simplified_debts` and `invite_link`. See [Response shape](#response-shape-view) — this is the response that does not fit at all on `full` |
| `sw_get_group(id, view?)` | Get a single group's details including members and balances |
| `sw_create_group(name, group_type?, simplify_by_default?)` | Create a new group (`group_type`: `apartment`, `house`, `trip`, `other`) |
| `sw_add_user_to_group(group_id, user_id?)` | Add a user by `user_id` (preferred) or `first_name` + `last_name` + `email` |
| `sw_remove_user_from_group(group_id, user_id)` | Remove a user from a group |

## Description:

Helps agents use Splitwise to check balances, groups, friends, and expenses and manage shared-expense records through MCP.

This skill is ready for commercial/non-commercial use.

## Publisher:

[chrischall](https://clawhub.ai/user/chrischall)

### License/Terms of Use:

MIT-0

## Use Case:

People and agents managing shared expenses use this skill to review Splitwise balances and records, add or edit expenses, manage groups and friends, and retrieve receipts.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The installed package receives a Splitwise API key and can read account balances, friends, expenses, and receipts.

Mitigation: Confirm that you trust the package before providing it with your Splitwise API key.

Risk: Approved write actions can create, change, delete, or restore Splitwise records.

Mitigation: Review the proposed changes and approve writes only when they match your intent.

Risk: Receipt retrieval can save files to the server filesystem.

Mitigation: Use inline receipt or text extraction modes when you do not want receipt files saved on the server.
