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 Bench account to Cowork via Composio Connect, enabling it to pause workflow for 10 seconds, simulate delay during test runs, wait before running next benchmark, and more such actions on your behalf without compromising your account security.

Connecting Bench to Claude Cowork

1. Open Customize

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

2. Add the Composio MCP server

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

3. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

4. Connect your Bench account

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

For example, ask Cowork to:

  • "Pause workflow for 10 seconds"
  • "Simulate delay during test runs"
  • "Wait before running next benchmark"

It will prompt you to authenticate and authorize access.

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

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

The Bench MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bench environment. It provides structured and secure access to benchmarking operations, so your agent can perform actions like simulating wait times, testing response delays, and orchestrating timed pauses within automated workflows.

  • Simulate processing delays: Instruct your agent to initiate a sleep or wait state, mimicking real-world processing or benchmarking scenarios.
  • Test agent response times: Have the agent pause for a set duration to measure how your applications handle delays or timeouts.
  • Orchestrate workflow timing: Use controlled sleep intervals to sequence multi-step tasks or coordinate between services during automation runs.
  • Benchmark system latency: Trigger sleep commands to evaluate how your systems and integrations perform under different timing constraints.

FAQ

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

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

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

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