By the end, you'll have a working Dnsfilter agent that can list all ip addresses in your network, retrieve billing information for your organization, get details for a specific filtering category through natural language commands. This guide will help you understand how to give your AutoGen agent real control over a Dnsfilter account through Composio's Dnsfilter MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Dnsfilter with - [OpenAI Agents SDK](https://composio.dev/toolkits/dnsfilter/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/dnsfilter/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/dnsfilter/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/dnsfilter/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/dnsfilter/framework/codex) - [OpenClaw](https://composio.dev/toolkits/dnsfilter/framework/openclaw) - [Hermes](https://composio.dev/toolkits/dnsfilter/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/dnsfilter/framework/cli) - [Google ADK](https://composio.dev/toolkits/dnsfilter/framework/google-adk) - [LangChain](https://composio.dev/toolkits/dnsfilter/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/dnsfilter/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/dnsfilter/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/dnsfilter/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/dnsfilter/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 Dnsfilter - Wire that MCP URL into Autogen using McpWorkbench and StreamableHttpServerParams - Configure an Autogen AssistantAgent that can call Dnsfilter tools - Run a live chat loop where you ask the agent to perform Dnsfilter 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 Dnsfilter MCP server, and what's possible with it? The Dnsfilter MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Dnsfilter account. It provides structured and secure access to your DNSFilter environment, so your agent can perform actions like listing IPs, retrieving categories, managing network devices, and accessing billing information on your behalf. - Comprehensive IP address management: Direct your agent to list, fetch, or create IP address entries for your networks, streamlining network administration. - Efficient category and content filtering: Have your agent retrieve details for specific filtering categories or list all available content categories to fine-tune organizational policies. - Network device inventory automation: Ask your agent to list all MAC addresses and applications in your environment, making it easy to keep track of connected devices and services. - Application category insight: Instantly access information about application categories or retrieve all application categories to stay updated on your filtering options. - Billing information access: Let your agent pull detailed billing information for your organization, supporting audits and automated reporting workflows. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `DNSFILTER_CREATE_IP_ADDRESS` | Create IP Address | Tool to create a new ip address in dnsfilter. use after confirming the target network id exists. | | `DNSFILTER_GET_APPLICATION_CATEGORY` | Get Application Category | Tool to get basic information of a specific application category. use when you need details for a given application category id. | | `DNSFILTER_GET_BILLING_INFORMATION` | Get Billing Information | Tool to retrieve basic billing information for an organization. use when you need to obtain billing details for reporting or automation tasks. | | `DNSFILTER_GET_CATEGORY` | Get Category | Tool to get basic information of a specific category. use when you need to retrieve details for a category by its id. | | `DNSFILTER_GET_IP_ADDRESS` | Get IP Address | Tool to get basic information of the specified ip address. use when you need to fetch metadata for a particular ip after authentication. | | `DNSFILTER_LIST_ALL_CATEGORIES` | List All Categories | Tool to list all categories including internal categories. use when you need the complete set of filtering categories. | | `DNSFILTER_LIST_ALL_IP_ADDRESSES` | List All IP Addresses | Tool to list all user-associated ip addresses. use when you need a comprehensive list of all ip address entries in your organization. | | `DNSFILTER_LIST_ALL_MAC_ADDRESSES` | List All MAC Addresses | Tool to list all mac addresses with basic information. use when you need to retrieve all mac address entries in your organization. | | `DNSFILTER_LIST_APPLICATION_CATEGORIES` | List Application Categories | Tool to list application categories with basic information. use after authentication to retrieve all categories. | | `DNSFILTER_LIST_APPLICATIONS` | List Applications | Tool to list applications with basic information. use when you need to retrieve all applications for your dnsfilter organization. | | `DNSFILTER_LIST_BLOCK_PAGES` | List Block Pages | Tool to list block pages associated with the current user. use when you need to retrieve all block pages for review or update. | | `DNSFILTER_LIST_CATEGORIES` | List Categories | Tool to list categories with basic information. use when retrieving all dnsfilter categories for policy configuration. | | `DNSFILTER_LIST_INVOICES` | List Invoices | Tool to list invoices for an organization, most recent first. use after obtaining the organization id when needing paginated invoice data. | | `DNSFILTER_LIST_IP_ADDRESSES` | List IP Addresses | Tool to list user-associated ip addresses basic information. use when you need to retrieve paginated ip address records filtered by location or device after authentication. | | `DNSFILTER_LIST_MAC_ADDRESSES` | List MAC Addresses | Tool to list mac addresses associated with an organization. use when you need to retrieve basic mac address information, optionally filtered by organization or paginated. | | `DNSFILTER_LIST_NETWORKS` | List Networks | Tool to list all networks. use when you need to retrieve all network configurations for your organization. | | `DNSFILTER_LIST_ORGANIZATIONS` | List Organizations | Tool to list all organizations. use when you need to retrieve all organizations tied to the authenticated dnsfilter account. | | `DNSFILTER_SUGGEST_DOMAIN_THREAT` | Suggest Domain Threat | Tool to suggest a fqdn as a potential threat. use after identifying a suspicious domain to verify its threat categorization. | | `DNSFILTER_VALIDATE_AUTH0_JWT` | Validate Auth0 JWT | Tool to validate a jwt with auth0. use when you need to confirm token validity before making dnsfilter api calls. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Dnsfilter MCP server is an implementation of the Model Context Protocol that connects your AI agents and assistants directly to Dnsfilter. Instead of manually wiring Dnsfilter 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 Dnsfilter 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 Dnsfilter 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 Dnsfilter 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 Dnsfilter 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 Dnsfilter session composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY")) session = composio.create( user_id=os.getenv("USER_ID"), toolkits=["dnsfilter"] ) 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 Dnsfilter 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 Dnsfilter assistant agent with MCP tools agent = AssistantAgent( name="dnsfilter_assistant", description="An AI assistant that helps with Dnsfilter 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 Dnsfilter 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 Dnsfilter 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 Dnsfilter session composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY")) session = composio.create( user_id=os.getenv("USER_ID"), toolkits=["dnsfilter"] ) 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 Dnsfilter assistant agent with MCP tools agent = AssistantAgent( name="dnsfilter_assistant", description="An AI assistant that helps with Dnsfilter 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 Dnsfilter 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 Dnsfilter 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 Dnsfilter, you can reuse the same structure for other MCP-enabled apps with minimal code changes. ## How to build Dnsfilter MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/dnsfilter/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/dnsfilter/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/dnsfilter/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/dnsfilter/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/dnsfilter/framework/codex) - [OpenClaw](https://composio.dev/toolkits/dnsfilter/framework/openclaw) - [Hermes](https://composio.dev/toolkits/dnsfilter/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/dnsfilter/framework/cli) - [Google ADK](https://composio.dev/toolkits/dnsfilter/framework/google-adk) - [LangChain](https://composio.dev/toolkits/dnsfilter/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/dnsfilter/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/dnsfilter/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/dnsfilter/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/dnsfilter/framework/crew-ai) ## Related Toolkits - [Apilio](https://composio.dev/toolkits/apilio) - Apilio is a home automation platform that lets you connect and control smart devices from different brands.

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