pirate-borg-mcp

An MCP server for Pirate Borg. Gives an LLM the tools it needs to generate stat-accurate NPCs using the procedural tables from the rulebook.

Tools

create_character

Generates a Pirate Borg NPC. The LLM provides narrative fields (name, faction, description, attack, inventory); the server rolls all numerical values from the enemy generator tables: HP, morale, armor tier, and the five ability score modifiers (Strength, Agility, Presence, Toughness, Spirit).

The LLM can optionally override hp_tier (1–10) or armor_tier (0–3) — useful for intentionally tough or lightly armored characters.

Returns a formatted markdown stat block.
