# Frihet MCP Skill

Business assistant inside Claude Code. Manage invoices, expenses, clients, products, and quotes in plain language — with built-in Spanish tax intelligence.

**Requires:** Frihet account with API access + `@frihet/mcp-server` configured as MCP server.

## Setup

### 1. Configure the MCP server

Add to your Claude Code MCP config (`~/.claude/mcp.json` or project `.mcp.json`):

```json
{
  "mcpServers": {
    "frihet": {
      "command": "npx",
      "args": ["@frihet/mcp-server"],
      "env": {
        "FRIHET_API_KEY": "fri_your_api_key_here"
      }
    }
  }
}
```

Get your API key at **app.frihet.io > Settings > API**.

### 2. Verify

Run `/frihet status` — if you see your account info, you're ready.

## Commands

| Command | What it does | Example |
|---------|-------------|---------|
| `/frihet status` | Account overview: recent invoices, pending payments, month's expenses | `/frihet status` |
| `/frihet invoice` | Create, list, search invoices | `/frihet invoice "Acme 3500 EUR consulting enero"` |
| `/frihet expense` | Log and query expenses | `/frihet expense "47.50 gasolina 15 feb"` |
| `/frihet clients` | Manage client database | `/frihet clients "Acme"` |
| `/frihet quote` | Create and manage quotes | `/frihet quote create` |
| `/frihet report` | Financial summaries and P&L | `/frihet report quarterly` |
| `/frihet webhooks` | Configure automation triggers | `/frihet webhooks` |
| `/frihet setup` | Guided connection setup | `/frihet setup` |

## MCP Tools (35 total)

| Resource | Tools | Operations |
|----------|-------|------------|
| Intelligence | 4 | get_business_context, get_monthly_summary, get_quarterly_taxes, duplicate_invoice |
| Invoices | 6 | list, get, create, update, delete, search |
| Expenses | 5 | list, get, create, update, delete |
| Clients | 5 | list, get, create, update, delete |
| Products | 5 | list, get, create, update, delete |
| Quotes | 5 | list, get, create, update, delete |
| Webhooks | 5 | list, get, create, update, delete |

## Core Decision Logic

### Tax Rate Selection

Determine the correct tax based on the client's fiscal zone:

| Fiscal Zone | Tax | General Rate | Reduced | Super-reduced |
|-------------|-----|-------------|---------|---------------|
| `peninsula` | IVA | 21% | 10% | 4% |
| `canarias` | IGIC | 7% | 3% | 0% |
| `ceuta_melilla` | IPSI | 10% | — | — |
| `eu` | Reverse charge | 0% | — | — |
| `world` | Exempt | 0% | — | — |

**Decision flow for invoices:**
1. Check the client's address/fiscal zone
2. If `peninsula` → apply IVA at the rate matching the product/service type
3. If `canarias` → apply IGIC instead of IVA
4. If `eu` → 0% with "Inversión del sujeto pasivo" / "Reverse charge" note
5. If `world` → 0% exempt, no tax line

**IRPF retention (professional services only):**
- Standard: 15%
- New autónomo (first 3 years): 7%
- Only applies when invoicing as a professional to a business (B2B peninsula)

For full tax details including quarterly models, deadlines, and expense deductibility rules, see `references/tax-guide.md`.

### Expense Categorization

Auto-categorize expenses by matching keywords in the description:

| Category | Keywords (ES/EN) |
|----------|-----------------|
| `office` | oficina, papelería, material, supplies, stationery |
| `technology` | software, SaaS, hosting, dominio, hardware, cloud |
| `travel` | viaje, vuelo, tren, hotel, parking, flight, train |
| `food` | comida, restaurante, café, meal, lunch, dinner |
| `vehicle` | gasolina, combustible, fuel, peaje, toll, mantenimiento |
| `professional` | asesoría, gestoría, abogado, notario, consulting |
| `marketing` | publicidad, ads, diseño, campaign, SEO, social |
| `general` | anything that doesn't match above |

### Invoice Status Flow

```
draft → sent → paid
              → overdue → paid
                        → cancelled
```

Rectificativa (credit note) types: R1 (error), R2 (insolvency), R3 (discount), R4 (other), R5 (simplified).

### Quote Status Flow

```
draft → sent → accepted → (convert to invoice)
             → rejected
             → expired
```

## Key Workflows

Brief workflow outlines — for detailed step-by-step recipes, see `references/workflows.md`.

**Monthly close** ("cierre mensual"): List month's invoices + expenses → calculate income, expenses, IVA collected vs paid, net result → flag unpaid invoices.

**Tax prep 303** ("IVA trimestral", "303"): Sum quarter's IVA repercutido (invoices) - IVA soportado (deductible expenses) → present pre-filled 303 data.

**Client onboarding**: Create client → optionally create product → create invoice → confirm.

**Expense batch** ("gastos del mes"): Parse multiple expenses → create each with auto-categorized category → summary table with deductible split.

**Overdue follow-up** ("morosos"): List overdue invoices → sort by amount → suggest follow-up actions.

**Quote to invoice**: Get accepted quote → create invoice copying client/items/notes → mark quote as accepted.

## Error Handling

| Error | What to tell the user | Action |
|-------|----------------------|--------|
| 401 Unauthorized | "API key inválida o expirada. Revisa tu configuración en app.frihet.io > Settings > API." | Guide to `/frihet setup` |
| 404 Not Found | "No encontré ese recurso. Comprueba el ID o busca por nombre." | Suggest search tool |
| 429 Rate Limited | "Demasiadas peticiones. Esperando {retryAfter}s..." | Auto-retry with backoff |
| Network Error | "No puedo conectar con Frihet. Verifica tu conexión." | Check MCP server status |
| No MCP Server | "El servidor MCP de Frihet no está configurado. Ejecuta `/frihet setup`." | Guide setup |

For full error code reference and pagination patterns, see `references/api-patterns.md`.

## Language Rules

- Respond in the same language the user writes in
- Default to Spanish (ES) for financial terms and tax references
- Keep Spanish terms for tax models (Modelo 303, IRPF, IVA) even in English — they have no direct translation
- Currency is always EUR. Format: `1,234.56 EUR` (dot for decimals, comma for thousands)

## Security

- **Never** log, display, or store the API key in conversation output
- **Never** include the API key in code snippets shown to the user
- API key is managed exclusively via environment variables in MCP config
- All data stays between Claude Code, the MCP server, and Frihet's API
- The MCP server is stateless — stores nothing
- If a user asks to see their API key, direct them to app.frihet.io
