Introduction

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks.

This guide walks you through the easiest and most secure way to connect your Fly account to Cowork via Composio Connect, enabling it to deploy latest image to Fly in Tokyo, list all running Fly apps by region, scale up your Fly app to 3 instances, and more such actions on your behalf without compromising your account security.

4. Connect your Fly account

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

For example, ask Cowork to:

  • "Deploy latest image to Fly in Tokyo"
  • "List all running Fly apps by region"
  • "Scale up your Fly app to 3 instances"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Fly 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 Fly through MCP without you sharing account credentials directly with the agent.

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

The Fly MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Fly account. It provides structured and secure access so your agent can perform Fly operations on your behalf.

How to build Fly MCP Agent with another framework

FAQ

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

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

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

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