## Overview

A production-grade Python library for intangible asset valuation, implementing every formula from the **[Intangible Asset Valuation](https://www.amazon.com/Intangible-Asset-Valuation-Comprehensive-Technology/dp/B0FZ8742R1)** textbook by Simon Mak, William Yuen, Paul Wu, and Wayne Hu (Valuation in Practice Series, Ascent Partners). Designed for developers, financial analysts, accountants, and AI agents who need auditable, structured valuation computations for ASC 805 / IFRS 3 compliant workflows.

1. **Python Library** — 22 modules, 124+ typed functions, all returning `ValuationResult` (value + assumptions + steps + formula reference)
2. **MCP Server** — 14 folded tools (124+ formulas) for AI agents via stdio and hosted Streamable HTTP
3. **AI-agent skills** — 4 skill definitions with workflow guidance for valuation domains

## Installation

```bash
pip install intangible-valuation          # library only
pip install intangible-valuation[mcp]     # + MCP server
pip install intangible-valuation[dev]     # + pytest, ruff, mypy
```

## Quick Start

### Python Library

```python
from intangible_valuation.core.time_value import present_value
from intangible_valuation.core.discount_rates import build_up_discount_rate
from intangible_valuation.income_methods.relief_from_royalty import relief_from_royalty

# Present Value
result = present_value(future_value=500_000, discount_rate=0.10, periods=8)
print(f"PV: ${result.value:,.2f}")  # $233,253.69

# Build-Up Discount Rate
rate = build_up_discount_rate(
    risk_free_rate=0.04, equity_risk_premium=0.06,
    size_premium=0.02, industry_risk_premium=0.01, specific_risk_premium=0.03,
)
print(f"Discount rate: {rate.value:.2%}")  # 16.00%

# Relief from Royalty — Patent Valuation
value = relief_from_royalty(
    revenue_projections=[1_000_000, 1_100_000, 1_200_000, 1_300_000, 1_400_000],
    royalty_rate=0.05, discount_rate=0.12, tax_rate=0.25, useful_life=5,
)
print(f"Patent value: ${value.value:,.2f}")
```

### MCP Server (for AI Agents)

The server exposes **14 tools**, each folding a family of formulas behind a
`method` argument — time value, discount rates, cost/market/income approaches,
IP, technology, customer and human-capital assets, goodwill and purchase price
allocation, impairment, royalty analysis, uncertainty (Monte Carlo / decision
trees), and transfer-pricing / litigation.

**Local (stdio):**

```bash
pip install "intangible-valuation[mcp]"
python mcp_server/server.py
```

**Hosted (Streamable HTTP)** — no install, no API key:

```
https://intangible-valuation.simonmak.com/api/mcp
```

**OpenCode** — add to `opencode.json`:

```json
"intangible-valuation": {
  "type": "remote",
  "url": "https://intangible-valuation.simonmak.com/api/mcp",
  "timeout": 60000
}
```

**Claude Desktop / Cursor** — add the HTTP URL
`https://intangible-valuation.simonmak.com/api/mcp` as an MCP server, or run the
stdio entrypoint above.

**MCP Registry & Glama** — published as
`io.github.simonmak-ascent/intangible-valuation`. The
[`server.json`](server.json) manifest declares both the hosted
`streamable-http` remote and a PyPI **stdio** package, and
[`glama.json`](glama.json) carries the Glama listing. Install and run the stdio
server from either registry:

```bash
pip install "intangible-valuation[mcp]" && intangible-valuation-mcp   # pip
uvx --from intangible-valuation intangible-valuation-mcp              # uvx (no install)
```

Listed on
[Glama](https://glama.ai/mcp/servers/simonmak-ascent/intangible-valuation) and
the [Official MCP Registry](https://registry.modelcontextprotocol.io).


**Prompts and resources.** Besides the 14 tools, the server offers three guided
prompts (`purchase_price_allocation`, `value_ip_asset`, `impairment_test`) and a
machine-readable method catalog at `intangible-valuation://methods`, so agents can
see every method's required parameters before calling a tool.

### AI-agent skills

Copy the `skills/` directory to your agent's skills folder:

- **`asset-valuation`** — Patents, trademarks, technology, customer relationships, human capital
- **`discount-rate-construction`** — Build-up, CAPM, WACC, risk premiums, adjustments
- **`purchase-price-allocation`** — ASC 805 / IFRS 3 PPA workflow, goodwill calculation
- **`impairment-testing`** — ASC 350, IAS 36 goodwill and intangible impairment
