4. Connect your Dnsfilter account

Back in Cowork, ask the agent to connect to Dnsfilter or give it any Dnsfilter-related task.

For example, ask Cowork to:

  • "List all IP addresses in your network"
  • "Retrieve billing information for your organization"
  • "Get details for a specific filtering category"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Dnsfilter account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Dnsfilter through MCP without you sharing account credentials directly with the agent.

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.

FAQ

What are the differences in Tool Router MCP and Dnsfilter MCP?

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 Cowork?

Yes, you can. Claude Cowork 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.
