By the end, you'll have a working Clearout agent that can validate a list of emails for deliverability, check if this email is a business account, find the most likely domain for acme corp through natural language commands. This guide will help you understand how to give your Google ADK agent real control over a Clearout account through Composio's Clearout MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Clearout with - [OpenAI Agents SDK](https://composio.dev/toolkits/clearout/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/clearout/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/clearout/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/clearout/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/clearout/framework/codex) - [OpenClaw](https://composio.dev/toolkits/clearout/framework/openclaw) - [Hermes](https://composio.dev/toolkits/clearout/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/clearout/framework/cli) - [LangChain](https://composio.dev/toolkits/clearout/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/clearout/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/clearout/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/clearout/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/clearout/framework/crew-ai) ## TL;DR Here's what you'll learn: - Get a Clearout account set up and connected to Composio - Install the Google ADK and Composio packages - Create a Composio Tool Router session for Clearout - Build an agent that connects to Clearout through MCP - Interact with Clearout 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 Clearout MCP server, and what's possible with it? The Clearout MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Clearout account. It provides structured and secure access to email validation, prospecting, and enrichment tools, so your agent can perform actions like verifying email addresses, finding business contacts, checking domain details, and bulk-processing lists on your behalf. - AI-powered email verification: Instantly validate single or bulk email addresses to ensure deliverability and reduce bounce rates. - Email prospecting and enrichment: Find emails for people or companies, complete missing contact data, and verify if accounts are business or personal. - Domain and company intelligence: Retrieve company domains from names, fetch MX records, or pull WHOIS information to understand your leads and their infrastructure. - Disposable and catch-all detection: Check if an email is temporary or if a domain accepts all mail, helping you maintain list quality and avoid spam traps. - Bulk job automation: Upload, process, monitor, cancel, and download results for large-scale email finding and verification tasks, all through your agent. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CLEAROUT_AUTOCOMPLETE_COMPANY_TO_DOMAIN` | Autocomplete Company to Domain | Tool to autocomplete company names to probable domains with confidence scores.

It provides structured and secure access so your agent can perform Clearout 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 Clearout 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=["clearout"], ) 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 Clearout 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=["clearout"], ) 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 Clearout operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ## Conclusion You've successfully integrated Clearout with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Clearout using natural language commands. Key takeaways: - The Tool Router approach dynamically routes requests to the appropriate Clearout 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 Clearout MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/clearout/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/clearout/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/clearout/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/clearout/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/clearout/framework/codex) - [OpenClaw](https://composio.dev/toolkits/clearout/framework/openclaw) - [Hermes](https://composio.dev/toolkits/clearout/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/clearout/framework/cli) - [LangChain](https://composio.dev/toolkits/clearout/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/clearout/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/clearout/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/clearout/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/clearout/framework/crew-ai) ## Related Toolkits - [Aeroleads](https://composio.dev/toolkits/aeroleads) - Aeroleads is a B2B lead generation platform for finding business emails and phone numbers.

With a standalone Clearout MCP server, the agents and LLMs can only access a fixed set of Clearout tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Clearout 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 Clearout tools. ### Can I manage the permissions and scopes for Clearout while using Tool Router? Yes, absolutely. You can configure which Clearout 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 Clearout data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
