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

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

The Telnyx MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Telnyx account. It provides structured and secure access to your Telnyx communications platform, so your agent can manage networks, handle notification channels, monitor usage, and review account activities on your behalf.

  • Network provisioning and management: Easily create or delete network resources, allowing your agent to spin up new networks or remove unused ones as needed.
  • Notification channel automation: Set up, configure, or remove notification channels—including SMS, voice, email, or webhook endpoints—so your agent can handle event-driven communications flexibly.
  • Notification profile and settings control: Group and configure notification profiles and settings, enabling your agent to define how and when notifications are delivered for different events.
  • Real-time balance monitoring: Retrieve your current account balance and credit details, helping your agent keep tabs on usage and alert you before credits run low.
  • Comprehensive audit log access: Review detailed audit logs so your agent can surface recent changes, track resource modifications, and help maintain compliance or troubleshoot issues quickly.

How to build Telnyx MCP Agent with another framework

FAQ

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

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

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

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