## 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** — published as
`io.github.simonplmak-cloud/intangible-valuation` (manifest:
[`server.json`](server.json)) and listed on
[Glama](https://glama.ai/mcp/servers/simonplmak-cloud/intangible-valuation) and
the [Official MCP Registry](https://registry.modelcontextprotocol.io). The
[`glama.json`](glama.json) file holds the Glama maintainer entry.
### 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

TDQS
A4.9/5.0
Scored across 14 tools
Disambiguation4/5
Each tool targets a distinct valuation area (impairment, rate construction, cost/market/income approaches, asset types, goodwill, royalty, simulation, compliance), and descriptions cross-reference alternatives. Minor overlap exists between general tools like valuation_income_methods and dedicated asset tools (valuation_ip, valuation_technology, valuation_customer), but the guidance to prefer dedicated tools when applicable reduces misselection.
Naming Consistency5/5
All 14 tools use the same valuation_ prefix followed by a descriptive snake_case name. The pattern is predictable and unambiguous.
Tool Count5/5
Fourteen tools are well within a reasonable range for a broad intangible asset valuation domain. Each tool is a multi-method dispatcher, so the effective functional surface is large but organized into coherent buckets.
Completeness5/5
The surface covers the full valuation lifecycle: rate construction, time value, cost/market/income approaches, all major intangible asset classes, goodwill PPA, impairment, royalty analysis, simulation, and compliance. No obvious operational gap exists for the stated domain.
