You can do this in two different ways: - Via [Composio Connect](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code) - Direct and easiest approach - Via [Composio SDK](https://docs.composio.dev/docs?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=composio_sdk) - Programmatic approach with more control ## 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 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 - Only one MCP URL to connect multiple apps with Claude Code with zero auth hassles. - Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Handling Large tool responses out of LLM context to minimize context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need. ## Connect Dnsfilter to Claude Code ### Connecting Dnsfilter to Claude Code using Composio 1. Add the Composio MCP to Claude ```bash claude mcp add --scope user --transport http composio https://connect.composio.dev/mcp ``` ## What is Claude Code? Claude Code is Anthropic's command line developer tool that lets you use Claude directly inside your terminal. Instead of switching between your editor, browser, and chat, you can stay in your project folder and ask Claude to help you build, debug, refactor, and understand code right where you're working. Key features include: - Terminal-Native Experience: Work with Claude directly in your command line without switching contexts - MCP Support: Built-in support for Model Context Protocol servers to extend Claude's capabilities - Project Context: Claude understands your project structure and can read, write, and modify files - Interactive Development: Ask questions, debug code, and get help in real-time while coding - Multi-Platform: Works on macOS, Linux, WSL, and Windows ## 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 Claude Code (and other AI assistants like Claude and Cursor) directly to your Dnsfilter account. It provides structured and secure access so Claude can perform Dnsfilter operations on your behalf. 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: - Claude Pro, Max, or API billing enabled Anthropic account - Composio API Key - A Dnsfilter account - Basic knowledge of Python or TypeScript ### 1. Install Claude Code To install Claude Code, use one of the following methods based on your operating system: ```bash # macOS, Linux, WSL curl -fsSL https://claude.ai/install.sh | bash # Windows PowerShell irm https://claude.ai/install.ps1 | iex # Windows CMD curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd ``` ### 2. Set up Claude Code Open a terminal, go to your project folder, and start Claude Code: - Claude Code will open in your terminal - Follow the prompts to sign in with your Anthropic account - Complete the authentication flow - Once authenticated, you can start using Claude Code ```bash cd your-project-folder claude ``` ### 3. Set up environment variables Create a .env file in your project root with the following variables: - COMPOSIO_API_KEY authenticates with Composio (get it from [Composio dashboard](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=api_key&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code)) - USER_ID identifies the user for session management (use any unique identifier) ```bash COMPOSIO_API_KEY=your_composio_api_key_here USER_ID=your_user_id_here ``` ### 4. Install Composio library No description provided. ```python pip install composio-core python-dotenv ``` ```typescript npm install @composio/core dotenv ``` ### 5. Generate Composio MCP URL No description provided. ```python import os from composio import Composio from dotenv import load_dotenv load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") USER_ID = os.getenv("USER_ID") composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=USER_ID, toolkits=["dnsfilter"], ) COMPOSIO_MCP_URL = composio_session.mcp.url print(f"MCP URL: {COMPOSIO_MCP_URL}") print(f"\nUse this command to add to Claude Code:") print(f'claude mcp add --transport http dnsfilter-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"') ``` ```typescript import 'dotenv/config'; import { Composio } from '@composio/core'; const { COMPOSIO_API_KEY, USER_ID } = process.env; if (!COMPOSIO_API_KEY || !USER_ID) { throw new Error('COMPOSIO_API_KEY and USER_ID required in .env'); } const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY }); const composioSession = await composioClient.create(USER_ID, { toolkits: ['dnsfilter'], }); const composioMcpUrl = composioSession?.mcp.url; console.log(`MCP URL: ${composioMcpUrl}`); console.log(`\nUse this command to add to Claude Code:`); console.log(`claude mcp add --transport http dnsfilter-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`); ``` ### 6. Run the script and copy the MCP URL No description provided. ```python python generate_mcp_url.py ``` ```typescript node --loader ts-node/esm generate_mcp_url.ts # or if using tsx tsx generate_mcp_url.ts ``` ### 7. Add Dnsfilter MCP to Claude Code In your terminal, add the MCP server using the command from the previous step. The command format is: - claude mcp add registers a new MCP server with Claude Code - --transport http specifies that this is an HTTP-based MCP server - The server name (dnsfilter-composio) is how you'll reference it - The URL points to your Composio Tool Router session - --headers includes your Composio API key for authentication After running the command, close the current Claude Code session and start a new one for the changes to take effect. ```bash claude mcp add --transport http dnsfilter-composio "YOUR_MCP_URL_HERE" --headers "X-API-Key:YOUR_COMPOSIO_API_KEY" # Then restart Claude Code exit claude ``` ### 8. Verify the installation Check that your Dnsfilter MCP server is properly configured. - This command lists all MCP servers registered with Claude Code - You should see your dnsfilter-composio entry in the list - This confirms that Claude Code can now access Dnsfilter tools If everything is wired up, you should see your dnsfilter-composio entry listed: ```bash claude mcp list ``` ### 9. Authenticate Dnsfilter The first time you try to use Dnsfilter tools, you'll be prompted to authenticate. - Claude Code will detect that you need to authenticate with Dnsfilter - It will show you an authentication link - Open the link in your browser (or copy/paste it) - Complete the Dnsfilter authorization flow - Return to the terminal and start using Dnsfilter through Claude Code Once authenticated, you can ask Claude Code to perform Dnsfilter operations in natural language. For example: - "List all IP addresses in my network" - "Retrieve billing information for my organization" - "Get details for a specific filtering category" ## Complete Code ```python import os from composio import Composio from dotenv import load_dotenv load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") USER_ID = os.getenv("USER_ID") composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=USER_ID, toolkits=["dnsfilter"], ) COMPOSIO_MCP_URL = composio_session.mcp.url print(f"MCP URL: {COMPOSIO_MCP_URL}") print(f"\nUse this command to add to Claude Code:") print(f'claude mcp add --transport http dnsfilter-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"') ``` ```typescript import 'dotenv/config'; import { Composio } from '@composio/core'; const { COMPOSIO_API_KEY, USER_ID } = process.env; if (!COMPOSIO_API_KEY || !USER_ID) { throw new Error('COMPOSIO_API_KEY and USER_ID required in .env'); } const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY }); const composioSession = await composioClient.create(USER_ID, { toolkits: ['dnsfilter'], }); const composioMcpUrl = composioSession?.mcp.url; console.log(`MCP URL: ${composioMcpUrl}`); console.log(`\nUse this command to add to Claude Code:`); console.log(`claude mcp add --transport http dnsfilter-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`); ``` ## Conclusion You've successfully integrated Dnsfilter with Claude Code using Composio's MCP server. Now you can interact with Dnsfilter directly from your terminal using natural language commands. Key features of this setup: - Terminal-native experience without switching contexts - Natural language commands for Dnsfilter operations - Secure authentication through Composio's managed MCP - Tool Router for dynamic tool discovery and execution Next steps: - Try asking Claude Code to perform various Dnsfilter operations - Add more toolkits to your Tool Router session for multi-app workflows - Integrate this setup into your development workflow for increased productivity You can extend this by adding more toolkits, implementing custom workflows, or building automation scripts that leverage Claude Code's capabilities. ## 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 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 Claude Code? Yes, you can. Claude Code 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)
