# ⚔️ Conqueror's Haki

<img src="icon.png" width="120" align="right" alt="Conqueror's Haki icon">

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

A [Model Context Protocol](https://modelcontextprotocol.io) (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.

```bash
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`):

```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**.
