## Description
Personal finance by conversation: expenses, receipts, statement import, budgets, net worth.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "myfinance-mcp": {
    "command": "npx",
    "args": ["-y","myfinance-mcp"]
  }
}
```

## Documentation & README

# MyFinance MCP

A remote MCP server for personal finance - log expenses by talking, snap receipt photos, import whole bank statements, and get budgets, trends and net worth computed for you, in any currency.

**Website:** [myfinance-mcp.com](https://myfinance-mcp.com) · Free while in beta · Built by [Rteam](https://rteam.agency)

## Quick Start

Already hosted and ready to use - just connect it to your MCP client:

```
https://myfinance-mcp.com/mcp
```

**On Claude.ai:** Customize → Connectors → **+** → Add custom connector → paste the URL → Connect. Leave the OAuth Client ID and Client Secret fields **empty** - filling them breaks sign-in.

**On ChatGPT:** Settings → Apps → Create app → paste the URL → choose OAuth → Create.

On first connect you sign in with Google or register with an email and password. Your data persists across reconnections.

## Why

- **No app, no forms, no spreadsheet.** "Spent 24.50 eur on groceries at Lidl" is the whole workflow.
- **Every number is computed in SQL.** The server owns the data and the math; the AI reads the results, it never guesses arithmetic.
- **Any currency.** Transactions keep their original currency; the FX rate to your base currency is frozen at transaction date, so history never rewrites itself.
- **Statements in one message.** Drop a CSV/PDF export; hundreds of rows import in one call with idempotent deduplication, hand-logged twins merged, totals reconciled.
- **Personal vs business.** Entity tag on accounts and transactions, filterable everywhere, included in CSV export for your accountant.
- **Dashboards in the chat.** Budgets, trends, summaries and accounts render as interactive panels (MCP Apps) right in the conversation.

## Tech Stack

- **Bun** - runtime and package manager
- **Express** - HTTP layer
- **MCP SDK** - Model Context Protocol over Streamable HTTP (stateless)
- **OAuth 2.1** - PKCE + dynamic client registration, Google sign-in optional
- **Prisma + PostgreSQL** - all money as `numeric`, all stats as SQL aggregates
- **Docker** - single container deployment

## MCP Apps

Four tools return an interactive dashboard (`ui://myfinancemcp/dashboard`) rendered directly in the chat on clients that support MCP Apps: budget rings, monthly trends, category summaries and the accounts/net-worth panel. Light and dark theme aware.

## Security & Privacy

- Receipt photos are parsed by YOUR AI client; images never reach this server.
- Amounts, merchants and notes are never written to server logs (blind logs); telemetry stores event types and ids only.
- OAuth 2.1 with PKCE, encrypted tokens, rate-limited sign-in.
- All 27 tools carry MCP annotations (read-only and destructive ops flagged, connector tools marked open-world), so clients can gate confirmations correctly.
- Bank access is strictly read-only: open banking consent via Enable Banking (the bank authenticates the user; we never see credentials), ZenMoney via the user's own API token. Session ids and tokens are stored AES-256-GCM encrypted.
- CSV export and instant full deletion are tools, not support tickets.
- Hosted instance: EU data residency, row-level security keyed to your account.
- 154 automated end-to-end checks (full OAuth flow, every tool, import dedup semantics, GDPR deletion) run in CI and as a hard deploy gate.

## Self-hosting

MIT-licensed; runs anywhere Bun and Postgres run.

### 1. Postgres

Any PostgreSQL 15+ works. [Supabase](https://supabase.com) free tier is a good fit: create a project and copy the **session pooler** connection string (IPv4).

Apply the schema:

```bash
bun install
bunx prisma db push
```

### 2. Environment variables

| Variable                      | Description                                                        |
| ----------------------------- | ------------------------------------------------------------------ |
| `PORT`                        | Server port (default `8788`)                                       |
| `BASE_URL`                    | Public URL of the server (OAuth issuer)                            |
| `DATABASE_URL`                | Postgres connection string                                         |
| `MYFINANCE_MCP_EMAIL`         | Bootstrap user email                                               |
| `MYFINANCE_MCP_PASSWORD_HASH` | Bootstrap user password hash (see below)                           |
| `GOOGLE_CLIENT_ID`            | _(optional)_ Google OAuth client ID for "Continue with Google"     |
| `GOOGLE_CLIENT_SECRET`        | _(optional)_ Google OAuth client secret                            |
| `RESEND_API_KEY`              | _(optional)_ Resend key for new-signup email notifications         |
| `NOTIFY_EMAIL`                | _(optional)_ Where signup notifications go                         |
| `FROM_EMAIL`                  | _(optional)_ Verified sender for notifications                     |
| `AUTO_SYNC_INTERVAL_MS`       | _(optional)_ Bank auto-sync tick, default hourly (syncs connections >20h stale); `0` disables |

Generate the password hash:

```bash
bun -e "console.log(await Bun.password.hash(process.argv[1]))" 'your-password'
```

### 3. Run

```bash
docker compose up -d      # uses the included Dockerfile, port 8788
```

Put nginx (or any TLS-terminating proxy) in front and point `BASE_URL` at your domain. The static landing in [`site/`](site/) is optional - serve it from the same origin if you want one.

## Development

```bash
bun install
cp .env.example .env   # fill in your values
bun run dev            # hot reload on :8788
bun run e2e            # self-contained end-to-end suite (spawns its own server)
bun run lint
```

The e2e suite (154 checks) covers the full OAuth flow (discovery, dynamic registration, PKCE, refresh rotation), every tool, statement-import dedup semantics, ZenMoney sync against a stubbed Diff API, and GDPR deletion.
