## TL;DR

Here's what you'll learn:
- Get and set up your Claude/Anthropic and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Chatwork
- Configure an AI agent that can use Chatwork as a tool
- Run a live chat session where you can ask the agent to perform Chatwork operations

## What is Claude Agent SDK?

The Claude Agent SDK is Anthropic's official framework for building AI agents powered by Claude. It provides a streamlined interface for creating agents with MCP tool support and conversation management.
Key features include:
- Native MCP Support: Built-in support for Model Context Protocol servers
- Permission Modes: Control tool execution permissions
- Streaming Responses: Real-time response streaming for interactive applications
- Context Manager: Clean async context management for sessions

## What is the Chatwork MCP server, and what's possible with it?

The Chatwork MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Chatwork account. It provides structured and secure access to your chats, contacts, files, and rooms, so your agent can perform actions like sending messages, managing tasks, retrieving files, and organizing team communications on your behalf.
- Room and member management: Easily fetch all chat rooms, list members in any room, and keep your workspace organized by letting your agent handle the heavy lifting.
- Smart message retrieval and deletion: Have your agent pull recent messages from any chat, search for important info, or even delete specific messages when needed.
- File sharing and retrieval: Seamlessly upload files to any Chatwork room or retrieve details and download links for files already shared, making document collaboration a breeze.
- Contact and status insights: Instantly get a list of all your Chatwork contacts or check your current unread messages and task status without switching tabs.
- Automated task and notification workflows: Let your agent monitor unread messages, mentions, and tasks, helping you stay on top of communication and never miss an important update.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CHATWORK_CHATWORK_DELETE_MESSAGE` | Delete Message | This tool allows you to delete a specific message from a chatwork room by calling the delete endpoint at https://api.chatwork.com/v2/rooms/{room id}/messages/{message id}. it requires authentication using a chatwork api token provided in the x-chatworktoken header, and the necessary permissions to delete messages in the specified room. |
| `CHATWORK_GET_CHATWORK_CONTACTS` | Get Chatwork Contacts | This tool retrieves a list of all contacts from chatwork. it is a fundamental tool that fetches all contact information such as account id, room id, name, chatwork id, organization details, department, and avatar image url, without needing additional parameters beyond authentication. |
| `CHATWORK_GET_FILE` | Get Chatwork File | This tool retrieves information about a specific file in a chat room. the api endpoint get /v2/rooms/{room id}/files/{file id} provides file details such as file id, account id, message id, filename, filesize, upload time, and download url, which are useful for retrieving file metadata, verifying file existence, and managing file sharing within chatwork. |
| `CHATWORK_GET_MY_STATUS` | Get My Chatwork Status | This tool retrieves the current status of the authenticated user, including unread message counts and task status. it provides a quick overview of unread messages, mentions, and tasks, making it valuable for monitoring chatwork activity and building automation workflows. |
| `CHATWORK_GET_ROOM_MEMBERS` | Get Room Members | This tool retrieves a list of all members in a specified chatwork room using the endpoint get /rooms/{room id}/members. it provides essential details like account id, role, name, chatwork id, organization id, and organization name, complementing the existing suite of room management tools. |
| `CHATWORK_GET_ROOM_MESSAGES` | Get Room Messages | This tool retrieves messages from a specific chatwork room using the get https://api.chatwork.com/v2/rooms/{room id}/messages endpoint. it requires a room id parameter and an optional force flag to refresh the cache by retrieving the 100 newest messages. |
| `CHATWORK_GET_ROOMS` | Get Chatwork Rooms | This tool retrieves a list of all chat rooms associated with the authenticated chatwork account. it includes group chats, direct chats, and personal chats, and does not require any additional parameters beyond authentication. |
| `CHATWORK_UPLOAD_FILE` | Upload File to Chatwork Room | This tool allows users to upload files to a specific chatwork room. it enables file sharing functionality within the chatwork platform by providing an endpoint to upload files (along with an optional message) to a given room. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Chatwork MCP server is an implementation of the Model Context Protocol that connects your AI agent to Chatwork. It provides structured and secure access so your agent can perform Chatwork operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Composio API Key and Claude/Anthropic API Key
- Primary know-how of Claude Agents SDK
- A Chatwork account
- Some knowledge of Python

### 1. Getting API Keys for Claude/Anthropic and Composio

Claude/Anthropic API Key
- Go to the [Anthropic Console](https://console.anthropic.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Navigate to your API settings and generate a new API key.
- Store this key securely as you'll need it for authentication.

### 2. Install dependencies

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Chatwork MCP?

With a standalone Chatwork MCP server, the agents and LLMs can only access a fixed set of Chatwork tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Chatwork and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Agent SDK?

Yes, you can. Claude Agent SDK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Chatwork tools.

### Can I manage the permissions and scopes for Chatwork while using Tool Router?

Yes, absolutely. You can configure which Chatwork scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Chatwork data and credentials are handled as safely as possible.
