# How to integrate Realphonevalidation MCP with Autogen ```json { "title": "How to integrate Realphonevalidation MCP with Autogen", "toolkit": "Realphonevalidation", "toolkit_slug": "realphonevalidation", "framework": "AutoGen", "framework_slug": "autogen", "url": "https://composio.dev/toolkits/realphonevalidation/framework/autogen", "markdown_url": "https://composio.dev/toolkits/realphonevalidation/framework/autogen.md", "updated_at": "2026-05-12T10:23:28.074Z" } ``` ## Introduction This guide walks you through connecting Realphonevalidation to AutoGen using the Composio tool router. By the end, you'll have a working Realphonevalidation agent that can check if this phone number is active, validate if a number is wireless or landline, verify if this email address is disposable through natural language commands. This guide will help you understand how to give your AutoGen agent real control over a Realphonevalidation account through Composio's Realphonevalidation MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Realphonevalidation with - [OpenAI Agents SDK](https://composio.dev/toolkits/realphonevalidation/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/realphonevalidation/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/realphonevalidation/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/realphonevalidation/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/realphonevalidation/framework/codex) - [OpenClaw](https://composio.dev/toolkits/realphonevalidation/framework/openclaw) - [Hermes](https://composio.dev/toolkits/realphonevalidation/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/realphonevalidation/framework/cli) - [Google ADK](https://composio.dev/toolkits/realphonevalidation/framework/google-adk) - [LangChain](https://composio.dev/toolkits/realphonevalidation/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/realphonevalidation/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/realphonevalidation/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/realphonevalidation/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/realphonevalidation/framework/crew-ai) ## TL;DR Here's what you'll learn: - Get and set up your OpenAI and Composio API keys - Install the required dependencies for Autogen and Composio - Initialize Composio and create a Tool Router session for Realphonevalidation - Wire that MCP URL into Autogen using McpWorkbench and StreamableHttpServerParams - Configure an Autogen AssistantAgent that can call Realphonevalidation tools - Run a live chat loop where you ask the agent to perform Realphonevalidation operations ## What is AutoGen? Autogen is a framework for building multi-agent conversational AI systems from Microsoft. It enables you to create agents that can collaborate, use tools, and maintain complex workflows. Key features include: - Multi-Agent Systems: Build collaborative agent workflows - MCP Workbench: Native support for Model Context Protocol tools - Streaming HTTP: Connect to external services through streamable HTTP - AssistantAgent: Pre-built agent class for tool-using assistants ## What is the Realphonevalidation MCP server, and what's possible with it? The Realphonevalidation MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Realphonevalidation account. It provides structured and secure access to advanced phone number and email verification services, so your agent can perform actions like real-time phone validation, carrier checks, bulk number scrubbing, and email deliverability checks on your behalf. - Instant phone number validation: Let your agent verify if a phone number is active, its type (mobile or landline), carrier, and caller details in real time. - Bulk number scrubbing: Automatically process and validate large lists of phone numbers, checking for connectivity and type to ensure data accuracy at scale. - Email address verification: Have your agent check if an email is deliverable and not disposable, helping prevent bouncebacks and spam risks. - Reassigned and consent compliance checks: Enable your agent to determine if a number has been reassigned since a specific consent date for regulatory compliance. - Carrier and wireless identification: Easily identify whether a US phone number is wireless or landline for TCPA compliance and segmentation. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `REALPHONEVALIDATION_CHECK_FRAUD` | Check Phone Fraud Risk | Tool to check phone number for fraud risk using Fraud Check API.

Instead of manually wiring Realphonevalidation APIs, OAuth, and scopes yourself, you get a structured, tool-based interface that an LLM can call safely. 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 You will need: - A Composio API key - An OpenAI API key (used by Autogen's OpenAIChatCompletionClient) - A Realphonevalidation account you can connect to Composio - Some basic familiarity with Autogen and Python async ### 1. Getting API Keys for OpenAI and Composio OpenAI API Key - Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider. - 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 Install Composio, Autogen extensions, and dotenv. What's happening: - composio connects your agent to Realphonevalidation via MCP - autogen-agentchat provides the AssistantAgent class - autogen-ext-openai provides the OpenAI model client - autogen-ext-tools provides MCP workbench support ```bash pip install composio python-dotenv pip install autogen-agentchat autogen-ext-openai autogen-ext-tools ``` ### 3. Set up environment variables Create a .env file in your project folder. What's happening: - COMPOSIO_API_KEY is required to talk to Composio - OPENAI_API_KEY is used by Autogen's OpenAI client - USER_ID is how Composio identifies which user's Realphonevalidation connections to use ```bash COMPOSIO_API_KEY=your-composio-api-key OPENAI_API_KEY=your-openai-api-key USER_ID=your-user-identifier@example.com ``` ### 4. Import dependencies and create Tool Router session What's happening: - load_dotenv() reads your .env file - Composio(api_key=...) initializes the SDK - create(...) creates a Tool Router session that exposes Realphonevalidation tools - session.mcp.url is the MCP endpoint that Autogen will connect to ```python import asyncio import os from dotenv import load_dotenv from composio import Composio from autogen_agentchat.agents import AssistantAgent from autogen_ext.models.openai import OpenAIChatCompletionClient from autogen_ext.tools.mcp import McpWorkbench, StreamableHttpServerParams load_dotenv() async def main(): # Initialize Composio and create a Realphonevalidation session composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY")) session = composio.create( user_id=os.getenv("USER_ID"), toolkits=["realphonevalidation"] ) url = session.mcp.url ``` ### 5. Configure MCP parameters for Autogen Autogen expects parameters describing how to talk to the MCP server. That is what StreamableHttpServerParams is for. What's happening: - url points to the Tool Router MCP endpoint from Composio - timeout is the HTTP timeout for requests - sse_read_timeout controls how long to wait when streaming responses - terminate_on_close=True cleans up the MCP server process when the workbench is closed ```python # Configure MCP server parameters for Streamable HTTP server_params = StreamableHttpServerParams( url=url, timeout=30.0, sse_read_timeout=300.0, terminate_on_close=True, headers={"x-api-key": os.getenv("COMPOSIO_API_KEY")} ) ``` ### 6. Create the model client and agent What's happening: - OpenAIChatCompletionClient wraps the OpenAI model for Autogen - McpWorkbench connects the agent to the MCP tools - AssistantAgent is configured with the Realphonevalidation tools from the workbench ```python # Create model client model_client = OpenAIChatCompletionClient( model="gpt-5", api_key=os.getenv("OPENAI_API_KEY") ) # Use McpWorkbench as context manager async with McpWorkbench(server_params) as workbench: # Create Realphonevalidation assistant agent with MCP tools agent = AssistantAgent( name="realphonevalidation_assistant", description="An AI assistant that helps with Realphonevalidation operations.", model_client=model_client, workbench=workbench, model_client_stream=True, max_tool_iterations=10 ) ``` ### 7. Run the interactive chat loop What's happening: - The script prompts you in a loop with You: - Autogen passes your input to the model, which decides which Realphonevalidation tools to call via MCP - agent.run_stream(...) yields streaming messages as the agent thinks and calls tools - Typing exit, quit, or bye ends the loop ```python print("Chat started! Type 'exit' or 'quit' to end the conversation.\n") print("Ask any Realphonevalidation related question or task to the agent.\n") # Conversation loop while True: user_input = input("You: ").strip() if user_input.lower() in ["exit", "quit", "bye"]: print("\nGoodbye!") break if not user_input: continue print("\nAgent is thinking...\n") # Run the agent with streaming try: response_text = "" async for message in agent.run_stream(task=user_input): if hasattr(message, "content") and message.content: response_text = message.content # Print the final response if response_text: print(f"Agent: {response_text}\n") else: print("Agent: I encountered an issue processing your request.\n") except Exception as e: print(f"Agent: Sorry, I encountered an error: {str(e)}\n") ``` ## Complete Code ```python import asyncio import os from dotenv import load_dotenv from composio import Composio from autogen_agentchat.agents import AssistantAgent from autogen_ext.models.openai import OpenAIChatCompletionClient from autogen_ext.tools.mcp import McpWorkbench, StreamableHttpServerParams load_dotenv() async def main(): # Initialize Composio and create a Realphonevalidation session composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY")) session = composio.create( user_id=os.getenv("USER_ID"), toolkits=["realphonevalidation"] ) url = session.mcp.url # Configure MCP server parameters for Streamable HTTP server_params = StreamableHttpServerParams( url=url, timeout=30.0, sse_read_timeout=300.0, terminate_on_close=True, headers={"x-api-key": os.getenv("COMPOSIO_API_KEY")} ) # Create model client model_client = OpenAIChatCompletionClient( model="gpt-5", api_key=os.getenv("OPENAI_API_KEY") ) # Use McpWorkbench as context manager async with McpWorkbench(server_params) as workbench: # Create Realphonevalidation assistant agent with MCP tools agent = AssistantAgent( name="realphonevalidation_assistant", description="An AI assistant that helps with Realphonevalidation operations.", model_client=model_client, workbench=workbench, model_client_stream=True, max_tool_iterations=10 ) print("Chat started! Type 'exit' or 'quit' to end the conversation.\n") print("Ask any Realphonevalidation related question or task to the agent.\n") # Conversation loop while True: user_input = input("You: ").strip() if user_input.lower() in ['exit', 'quit', 'bye']: print("\nGoodbye!") break if not user_input: continue print("\nAgent is thinking...\n") # Run the agent with streaming try: response_text = "" async for message in agent.run_stream(task=user_input): if hasattr(message, 'content') and message.content: response_text = message.content # Print the final response if response_text: print(f"Agent: {response_text}\n") else: print("Agent: I encountered an issue processing your request.\n") except Exception as e: print(f"Agent: Sorry, I encountered an error: {str(e)}\n") if __name__ == "__main__": asyncio.run(main()) ``` ## Conclusion You now have an Autogen assistant wired into Realphonevalidation through Composio's Tool Router and MCP. From here you can: - Add more toolkits to the toolkits list, for example notion or hubspot - Refine the agent description to point it at specific workflows - Wrap this script behind a UI, Slack bot, or internal tool Once the pattern is clear for Realphonevalidation, you can reuse the same structure for other MCP-enabled apps with minimal code changes. ## How to build Realphonevalidation MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/realphonevalidation/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/realphonevalidation/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/realphonevalidation/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/realphonevalidation/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/realphonevalidation/framework/codex) - [OpenClaw](https://composio.dev/toolkits/realphonevalidation/framework/openclaw) - [Hermes](https://composio.dev/toolkits/realphonevalidation/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/realphonevalidation/framework/cli) - [Google ADK](https://composio.dev/toolkits/realphonevalidation/framework/google-adk) - [LangChain](https://composio.dev/toolkits/realphonevalidation/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/realphonevalidation/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/realphonevalidation/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/realphonevalidation/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/realphonevalidation/framework/crew-ai) ## Related Toolkits - [Excel](https://composio.dev/toolkits/excel) - Microsoft Excel is a robust spreadsheet application for organizing, analyzing, and visualizing data.

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