By the end, you'll have a working Chatwork agent that can list all unread messages across rooms, upload meeting notes file to project room, get all members of marketing chat through natural language commands. This guide will help you understand how to give your Google ADK agent real control over a Chatwork account through Composio's Chatwork MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Chatwork with - [OpenAI Agents SDK](https://composio.dev/toolkits/chatwork/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/chatwork/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/chatwork/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/chatwork/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/chatwork/framework/codex) - [OpenClaw](https://composio.dev/toolkits/chatwork/framework/openclaw) - [Hermes](https://composio.dev/toolkits/chatwork/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/chatwork/framework/cli) - [LangChain](https://composio.dev/toolkits/chatwork/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/chatwork/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/chatwork/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/chatwork/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/chatwork/framework/crew-ai) ## TL;DR Here's what you'll learn: - Get a Chatwork account set up and connected to Composio - Install the Google ADK and Composio packages - Create a Composio Tool Router session for Chatwork - Build an agent that connects to Chatwork through MCP - Interact with Chatwork using natural language ## What is Google ADK? Google ADK (Agents Development Kit) is Google's framework for building AI agents powered by Gemini models. It provides tools for creating agents that can use external services through the Model Context Protocol. Key features include: - Gemini Integration: Native support for Google's Gemini models - MCP Toolset: Built-in support for Model Context Protocol tools - Streamable HTTP: Connect to external services through streamable HTTP - CLI and Web UI: Run agents via command line or web interface ## 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. | ## Supported Triggers None listed. ## 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: - A Google API key for Gemini models - A Composio account and API key - Python 3.9 or later installed - Basic familiarity with Python ### 1. Getting API Keys for Google and Composio Google API Key - Go to [Google AI Studio](https://aistudio.google.com/app/apikey) and create an API key. - Copy the key and keep it safe. You will put this in GOOGLE_API_KEY. Composio API Key and User ID - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Go to Settings → API Keys and copy your Composio API key. Use this for COMPOSIO_API_KEY. - Decide on a stable user identifier to scope sessions, often your email or a user ID. Use this for COMPOSIO_USER_ID. ### 2. Install dependencies Inside your virtual environment, install the required packages. What's happening: - google-adk is Google's Agents Development Kit - composio connects your agent to Chatwork via MCP - python-dotenv loads environment variables ```bash pip install google-adk composio python-dotenv ``` ### 3. Set up ADK project Set up a new Google ADK project. What's happening: - This creates an agent folder with a root agent file and .env file ```bash adk create my_agent ``` ### 4. Set environment variables Save all your credentials in the .env file. What's happening: - GOOGLE_API_KEY authenticates with Google's Gemini models - COMPOSIO_API_KEY authenticates with Composio - COMPOSIO_USER_ID identifies the user for session management ```bash GOOGLE_API_KEY=your-google-api-key COMPOSIO_API_KEY=your-composio-api-key COMPOSIO_USER_ID=your-user-id-or-email ``` ### 5. Import modules and validate environment What's happening: - os reads environment variables - Composio is the main Composio SDK client - GoogleProvider declares that you are using Google ADK as the agent runtime - Agent is the Google ADK LLM agent class - McpToolset lets the ADK agent call MCP tools over HTTP ```python import os import warnings from composio import Composio from dotenv import load_dotenv from google.adk.agents.llm_agent import Agent from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams from google.adk.tools.mcp_tool.mcp_toolset import McpToolset load_dotenv() warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*") GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") ``` ### 6. Create Composio client and Tool Router session What's happening: - Authenticates to Composio with your API key - Declares Google ADK as the provider - Spins up a short-lived MCP endpoint for your user and selected toolkit - Stores the MCP HTTP URL for the ADK MCP integration ```python composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=COMPOSIO_USER_ID, toolkits=["chatwork"], ) COMPOSIO_MCP_URL = composio_session.mcp.url, print(f"Composio MCP URL: {COMPOSIO_MCP_URL}") ``` ### 7. Set up the McpToolset and create the Agent What's happening: - Connects the ADK agent to the Composio MCP endpoint through McpToolset - Uses Gemini as the model powering the agent - Lists exact tool names in instruction to reduce misnamed tool calls ```python composio_toolset = McpToolset( connection_params=StreamableHTTPConnectionParams( url=COMPOSIO_MCP_URL, headers={"x-api-key": COMPOSIO_API_KEY} ) ) root_agent = Agent( model="gemini-2.5-flash", name="composio_agent", description="An agent that uses Composio tools to perform actions.", instruction=( "You are a helpful assistant connected to Composio. " "You have the following tools available: " "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, " "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. " "Use these tools to help users with Chatwork operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ### 8. Run the agent Execute the agent from the project root. The web command opens a web portal where you can chat with the agent. What's happening: - adk run runs the agent in CLI mode - adk web . opens a web UI for interactive testing ```bash # Run in CLI mode adk run my_agent # Or run in web UI mode adk web ``` ## Complete Code ```python import os import warnings from composio import Composio from composio_google import GoogleProvider from dotenv import load_dotenv from google.adk.agents.llm_agent import Agent from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams from google.adk.tools.mcp_tool.mcp_toolset import McpToolset load_dotenv() warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*") GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") composio_client = Composio(api_key=COMPOSIO_API_KEY, provider=GoogleProvider()) composio_session = composio_client.create( user_id=COMPOSIO_USER_ID, toolkits=["chatwork"], ) COMPOSIO_MCP_URL = composio_session.mcp.url composio_toolset = McpToolset( connection_params=StreamableHTTPConnectionParams( url=COMPOSIO_MCP_URL, headers={"x-api-key": COMPOSIO_API_KEY} ) ) root_agent = Agent( model="gemini-2.5-flash", name="composio_agent", description="An agent that uses Composio tools to perform actions.", instruction=( "You are a helpful assistant connected to Composio. " "You have the following tools available: " "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, " "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. " "Use these tools to help users with Chatwork operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ## Conclusion You've successfully integrated Chatwork with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Chatwork using natural language commands. Key takeaways: - The Tool Router approach dynamically routes requests to the appropriate Chatwork tools - Environment variables keep your credentials secure and separate from code - Clear agent instructions reduce tool calling errors - The ADK web UI provides an interactive interface for testing and development You can extend this setup by adding more toolkits to the toolkits array in your session configuration. ## How to build Chatwork MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/chatwork/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/chatwork/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/chatwork/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/chatwork/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/chatwork/framework/codex) - [OpenClaw](https://composio.dev/toolkits/chatwork/framework/openclaw) - [Hermes](https://composio.dev/toolkits/chatwork/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/chatwork/framework/cli) - [LangChain](https://composio.dev/toolkits/chatwork/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/chatwork/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/chatwork/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/chatwork/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/chatwork/framework/crew-ai) ## Related Toolkits - [Gmail](https://composio.dev/toolkits/gmail) - Gmail is Google's email service with powerful spam protection, search, and G Suite integration.

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 Google ADK? Yes, you can. Google ADK 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. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
