This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a Garoon MCP (Model Context Protocol) server that provides tools for interacting with the Garoon API. Garoon is a groupware application by Cybozu used for scheduling, collaboration, and organizational management. Garoon bundles various applications like the following.

• Scheduler(スケジュール)
• Workflow(ワークフロー)
• E-mail(メール)
• Messages(メッセージ)
• Space(スペース)
• Bulletin Board(掲示板)
• MultiReport(マルチレポート)
• Portal(ポータル)
• Cabinet(ファイル管理)
• Presence indicators(在籍情報)
• and more.

This MCP server mainly uses REST API. Garoon also has SOAP API, but it is legacy and its use is not recommended.

Architecture

Directory Layout

The source tree is organized by Garoon application, mirroring the Garoon REST API namespaces:

src/
  index.ts                 # composition only
  config.ts / client.ts / constants.ts
  core/                    # protocol-level infrastructure: register.ts (defineTool/registerTools), error-handler.ts, structured-output.ts
  schemas/                 # cross-application Garoon vocabulary (id, user, organization, datetime, pagination)
  applications/<app>/      # one directory per Garoon application (schedule, bulletin, base), matching Garoon REST API namespaces
    index.ts               # aggregated tool exports
    schemas/               # schemas shared by two or more tools within the application
    tools/<tool>/          # index.ts, handler.ts, input-schema.ts, output-schema.ts, tests/
