⚔️ Conqueror's Haki

An MCP server that cuts a long list down to the one to three things that actually matter right now.

A Model Context Protocol (MCP) server — one focused tool you plug into an MCP-compatible client (Claude Desktop, Claude Code, Cursor, and others).

What it does

Models tend to treat every item on a list as equally worthy of attention. That's the opposite of prioritization. Real prioritization means deciding what to ignore.

Conqueror's Haki takes a list and a single goal, forces a ruthless head-to-head ranking, and eliminates everything that doesn't directly serve that goal.

Usage

Give it your backlog and a North Star (e.g. "Launch a paid MVP in two weeks"). It returns:

• The Conquered — what was eliminated, each with a one-line reason it's a distraction
• The Standing Kings — the survivors, strictly ranked (at most three)
• Reason for Dominance — why each survivor earns the focus

Set strictness_level="Overwhelming" to force exactly one survivor.

Tool reference: assert_conquerors_haki(items_to_evaluate: list[str], north_star_goal: str, strictness_level: str = "Supreme King")

How it works

No API key, no cost, nothing leaves your machine. The server returns an engineered ranking prompt that your existing model executes — it makes no language-model call of its own.

Install

Requires Python 3.10 or newer.

pip install conquerors-haki-mcp

This installs the conquerors-haki command.

Then register it with your MCP client — either run claude mcp add conquerors-haki -- conquerors-haki, or add this to the client's config (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "conquerors-haki": { "command": "conquerors-haki" }
  }
}

Restart the client and the tool is available.

The Grand Line stack

Conqueror's Haki is part of a four-tool set. Each tool stands alone, but installing all of them unlocks a final surprise via Laugh Tale.
