## 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 Fixer io account to Cowork via Composio Connect, enabling it to convert 150 USD to EUR today, show exchange rate trends for GBP last month, list all supported currency codes and names, and more such actions on your behalf without compromising your account security.

## 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 Fixer io through MCP without you sharing account credentials directly with the agent.

## What is the Fixer io MCP server, and what's possible with it?

The Fixer io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Fixer io account. It provides structured and secure access to global currency exchange data, so your agent can perform actions like converting currencies, fetching historical rates, tracking exchange fluctuations, and listing supported symbols on your behalf.
- Real-time currency conversion: Instantly convert amounts between currencies using up-to-date or historical exchange rates with a single prompt.
- Fetch latest and historical rates: Let your agent retrieve the most recent exchange rates or get historical rates for any supported date to power financial analysis.
- Analyze currency fluctuations: Ask your agent to track and summarize day-to-day currency changes between two dates to monitor trends or volatility.
- Retrieve supported currency symbols: Quickly list all available currency codes and their full names to support app interfaces or custom workflows.
- Get exchange rate time series: Easily pull daily exchange rates over a custom period (up to 365 days) for detailed trend analysis or reporting.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Fixer io MCP?

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

### Can I manage the permissions and scopes for Fixer io while using Tool Router?

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