🏴‍☠️ Laugh Tale

The capstone of the Grand Line stack. Collect every tool, and it reveals the One Piece.

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

Laugh Tale is the final tool of the set. On its own it does nothing — it stays locked until you've installed the rest of the Grand Line stack.

Each tool, when it runs, leaves a marker in a shared folder (~/.grandline/poneglyphs/). Laugh Tale reads that folder. While any tool is missing, it tells you which ones you still need. Once every tool is present, the markers line up and it reveals the One Piece.

Usage

One tool:

• seek_the_one_piece — locked until every Grand Line tool is installed. Run it anytime: it either lists the tools still missing, or, when all are present, reveals the One Piece.

The reveal is a bit of fun, not a new capability — the other tools are the real treasure. It works purely off the shared marker folder, so the tools can live in completely separate packages and still count toward the unlock.

Tool reference: seek_the_one_piece()

How it works

No API key, fully local. It only reads the shared marker folder on your machine.

Install

Requires Python 3.10 or newer.

pip install laugh-tale-mcp

This installs the laugh-tale command.

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

{
  "mcpServers": {
    "laugh-tale": { "command": "laugh-tale" }
  }
}

Restart the client and the tool is available.

The Grand Line stack

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