# ⏳ Toki Toki no Mi

<img src="icon.png" width="120" align="right" alt="Toki Toki no Mi icon">

An MCP server that remembers **why** each decision was made — a local, searchable decision log.

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

A conversation's context window forgets. A few sessions later, the reasoning
behind an architectural choice is gone, and you re-litigate decisions you already
settled — or quietly reverse them without noticing.

Toki Toki no Mi is a **causality ledger**. It records each decision, the
alternatives you rejected, and why you chose as you did, then lets your assistant
retrieve that history later — and flag a new proposal that contradicts a past
decision.

## Usage

Two tools:

- `log_causality_point` — record a decision, the rejected alternatives, and the justification
- `time_leap_retrieval` — recall past decisions (all of them, or filtered by keyword)

Decisions are stored locally in SQLite under `~/.grandline/` and also mirrored to
a Markdown file, so any external search tool can be pointed at the folder to read
them.

**Tool reference:** `log_causality_point(decision_made, alternatives_rejected, justification)` · `time_leap_retrieval(query: str = "")`

## How it works

**Self-contained, no API key, fully local.** The ledger is a single SQLite file
on your machine with no external dependencies. Nothing is sent anywhere.

## Install

Requires Python 3.10 or newer.

```bash
pip install toki-toki-mcp
```

This installs the `toki-toki` command.

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

```json
{
  "mcpServers": {
    "toki-toki": { "command": "toki-toki" }
  }
}
```

Restart the client and the tool is available.

## The Grand Line stack

Toki Toki no Mi is part of a four-tool set. Each tool stands alone, but installing
all of them unlocks a final surprise via **Laugh Tale**.
