How to Set Up and Use Chatwork

The Chatwork MCP Server connects Claude to the Chatwork team messaging platform via the Chatwork API v2, enabling AI-driven management of chats, messages, tasks, and files. With over 40 tools covering user management, messaging, task tracking, file retrieval, and contact requests, it allows teams to automate routine communication workflows and query Chatwork data through natural language.

Prerequisites

  • A Chatwork API token (obtainable from Chatwork settings → API Token)
  • Node.js 16+ and npm installed
  • An MCP-compatible client such as Claude Desktop
1

Obtain a Chatwork API token

Log in to Chatwork, go to your account settings, find the API Token section, and generate or copy your personal API token. Keep it secure — it grants full API access to your account.

2

Install the MCP server package

The server is published as @chatwork/mcp-server on npm and can be run directly with npx without a global install.

npx -y @chatwork/mcp-server
3

Open Claude Desktop configuration

In Claude Desktop, go to Settings → Developer → Edit Configuration to open claude_desktop_config.json in your text editor.

4

Add the Chatwork server configuration

Add the mcpServers entry for Chatwork, providing your API token as the CHATWORK_API_TOKEN environment variable.

{
  "mcpServers": {
    "chatwork": {
      "command": "npx",
      "args": ["-y", "@chatwork/mcp-server"],
      "env": {
        "CHATWORK_API_TOKEN": "YOUR_CHATWORK_API_TOKEN"
      }
    }
  }
}
5

Restart Claude Desktop and verify

Save the configuration file and restart Claude Desktop. The Chatwork tools will appear in the connected tools list. Ask Claude to list your chats to confirm the connection works.

Chatwork Examples

Client configuration

Complete claude_desktop_config.json entry for the Chatwork MCP Server.

{
  "mcpServers": {
    "chatwork": {
      "command": "npx",
      "args": ["-y", "@chatwork/mcp-server"],
      "env": {
        "CHATWORK_API_TOKEN": "YOUR_CHATWORK_API_TOKEN"
      }
    }
  }
}

Prompts to try

Example prompts after connecting Claude to Chatwork.

- "List all my Chatwork rooms and their member counts"
- "Post a message to the 'Project Alpha' room saying the deployment is complete"
- "Show me all unread messages across my Chatwork rooms"
- "Create a task in the 'Engineering' room assigned to me: Review pull request by Friday"
- "List all pending files shared in the 'Design' room"
- "Show me my open tasks across all Chatwork rooms"

Troubleshooting Chatwork

Authentication error or 401 Unauthorized from Chatwork API

Verify the CHATWORK_API_TOKEN value is correct and has not expired. Go to Chatwork account settings and regenerate the token if needed, then update the config file and restart Claude Desktop.

npx hangs or fails to download @chatwork/mcp-server

Check your internet connection and npm registry access. Run 'npm install -g @chatwork/mcp-server' to install globally, then change the config to use 'command: "chatwork-mcp-server"' without args instead of npx.

Claude does not show Chatwork tools after configuration

Ensure the JSON in claude_desktop_config.json is valid (no trailing commas, correct nesting). Use a JSON validator, then fully quit and relaunch Claude Desktop — not just close the window.
