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 Tpscheck through MCP without you sharing account credentials directly with the agent.

What is the Tpscheck MCP server, and what's possible with it?

The Tpscheck MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Tpscheck account. It provides structured and secure access to UK phone number verification services, so your agent can instantly check TPS/CTPS registration, validate numbers, determine their type, and identify providers on your behalf.

  • Real-time TPS/CTPS registration checks: Instantly verify if any UK phone number is listed on the Telephone Preference Service (TPS) or Corporate TPS, ensuring compliance with marketing regulations.
  • Phone number validity verification: Quickly determine if a phone number is valid and active before using it for outreach or communication purposes.
  • Number type and classification detection: Identify whether a number is mobile, landline, or business, helping tailor your contact strategy accordingly.
  • Location and provider lookup: Retrieve geographic and telecom provider information for any UK number to better understand and segment your contact lists.

FAQ

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

With a standalone Tpscheck MCP server, the agents and LLMs can only access a fixed set of Tpscheck tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Tpscheck 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 Tpscheck tools.

Can I manage the permissions and scopes for Tpscheck while using Tool Router?

Yes, absolutely. You can configure which Tpscheck 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 Tpscheck data and credentials are handled as safely as possible.
