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

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

The Coinmarketcap MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Coinmarketcap account.

  • Real-time cryptocurrency price tracking: Instantly get the latest market quotes for any supported cryptocurrency, including price, volume, and market cap.
  • Comprehensive asset and exchange mapping: Retrieve and reference unique IDs, symbols, and names for all cryptocurrencies and exchanges to power portfolio and trading automations.
  • Historical listings and data analysis: Access historical exchange listings and past market snapshots to inform investment research or backtesting strategies.
  • Global market metrics aggregation: Let your agent pull up-to-date, aggregated market data like total market cap, trading volume, and dominance statistics for macro analysis.
  • Detailed asset and exchange metadata retrieval: Fetch rich metadata, including logos, descriptions, launch dates, and official links for any crypto asset or exchange—perfect for building dashboards or research tools.

FAQ

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

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

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

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