And MCP makes the experience even better. With Dnsfilter MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## 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) - [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 ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Dnsfilter to Codex ### How to install Dnsfilter MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## 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 provides comprehensive access to Dnsfilter operations through Composio.

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 Codex? Yes, you can. Codex 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)
