LiveMCPBench introduces the first large-scale benchmark evaluating AI agents' ability to navigate real-world tasks using Model Context Protocol (MCP) tools across multiple servers. The benchmark reveals significant performance gaps, with top model Claude-Sonnet-4 achieving 78.95% success while most models only reach 30-50%, identifying tool retrieval as the primary bottleneck.
Researchers introduce CoHyDE, an iterative co-training method that jointly optimizes a dense encoder and LLM rewriter to improve tool retrieval for AI agents. The approach outperforms single-component baselines by 2.5-8 percentage points on standard and vague queries, addressing the fundamental challenge of bridging colloquial user language with technical API vocabularies.
Researchers have released HumanMCP, the first large-scale dataset designed to evaluate tool retrieval performance in Model Context Protocol (MCP) servers. The dataset addresses a critical gap by providing realistic, human-like queries paired with 2,800 tools across 308 MCP servers, improving upon existing benchmarks that lack authentic user interaction patterns.
