Frequently asked questions

With a standalone HackerRank Work MCP server, the agents and LLMs can only access a fixed set of HackerRank Work tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from HackerRank Work and many other apps based on the task at hand, all through a single MCP endpoint.

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 HackerRank Work tools.
