The Loot Table Balancer MCP server provides a suite of specialized tools for game developers to manage item drop mechanics. Use normalize_weights to convert arbitrary weights into standardized percentages, estimate_cadence to predict item frequency over large gameplay sessions, compute_expected_value to determine the average economic gain per roll, and audit_rarity_distribution to validate your loot tables against industry-standard MMO rarity benchmarks.

Normalize these weights: [{'name': 'Iron Sword', 'weight': 50, 'rarity': 'COMMON'}, {'name': 'Dragon Slayer', 'weight': 1, 'rarity': 'LEGENDARY'}]

[{"name": "Iron Sword", "weight": 50, "rarity": "COMMON", "dropRate": 0.9803921568627451}, {"name": "Dragon Slayer", "weight": 1, "rarity": "LEGENDARY", "dropRate": 0.0196078431372549}]

How many times will a 0.01 drop rate item appear in 10,000 runs?

In 10,000 runs, you can expect that item to appear approximately 100 times.

What is the expected value if a Common item (50% rate) is worth 10 gold and an Epic item (5% rate) is worth 100 gold?

The expected value for this loot table roll is 10 gold.

Use the `normalize_weights` tool by providing a JSON array of items, where each object includes the name, weight, and rarity.
