intangible-valuation 1.0.1

Python library for intangible asset valuation implementing cost, market, and income approaches. 124+ functions for patents, brands, goodwill, PPA, and more.

Intangible Asset Valuation Engine

Complete intangible asset valuation library implementing 124+ functions from the Intangible Asset Valuation textbook. Python library + MCP server + AI-Agent Skills.

Overview

A production-grade Python library for intangible asset valuation, implementing every formula from the Intangible Asset Valuation 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.

Three-layer architecture:

1. Python Library — 22 modules, 124+ typed functions, all returning ValuationResult (value + assumptions + sensitivity)
2. MCP Server — 54 tools for AI agents (Claude, OpenCode, etc.) via stdio/SSE
3. AI-Agent Skills — 3 skill definitions with workflow guidance for valuation domains

Installation

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

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)

cd mcp_server && python server.py

Connect with any MCP-compatible AI agent. All 54 valuation tools available.

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
