🏴‍☠️ 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 island. 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.

Related MCP server: mcp-server-say-hello

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.

Set sail for Laugh Tale. Reveals the One Piece — but ONLY if every Road Poneglyph rubbing has been gathered (every fruit of the Grand Line stack installed). Otherwise it reports which poneglyphs are still missing.

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description fully carries the burden of behavioral disclosure. It clearly explains the dual outcome: success if all items are present, else reporting missing items. It does not mention side effects like destruction, but the behavior is well-described.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description consists of two sentences with no extraneous words. The main action is front-loaded, followed by a conditional elaboration, making it efficient and clear.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given zero parameters and the presence of an output schema, the description adequately covers the tool's behavior in both conditions. No further context is needed for effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0 parameters, so according to the guidelines, the baseline score is 4. The description adds no parameter information, which is acceptable because there are none to describe.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb 'reveals' and clearly states the tool's purpose: showing the One Piece if all Road Poneglyph rubbings are gathered, otherwise reporting missing ones. No sibling tools exist, so differentiation is not needed.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool (to check completeness of the Grand Line stack) and provides clear conditions. However, it does not explicitly state when not to use it or mention alternatives, though none are present.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4/5.0

Scored across 1 tool

Disambiguation5/5

With only one tool, there is no ambiguity. The tool's purpose is clear and distinct by default.

Naming Consistency4/5

The single tool name is descriptive and uses a verb_noun style (seek_the_one_piece), which is consistent within itself. A higher score is not applicable due to lack of multiple tools.

Tool Count1/5

A single tool is extremely limited for any meaningful server scope. Unless this is a highly specialized micro-service, the count is far too low for typical use cases.

Completeness1/5

The tool only provides a single conditional reveal action with no other operations (create, update, delete, list). The server lacks a complete surface for any domain.
