Researchers have introduced MCP-Atlas, a new benchmark designed to evaluate the tool-use capabilities of large language models. This benchmark features 36 real MCP servers and 220 tools, with 1,000 tasks requiring multi-step workflows and orchestration of multiple tool calls. Initial evaluations on advanced models show that while top performers exceed 50% pass rates, common failures stem from issues in tool usage and task comprehension. AI
