AI agents select better-described API tools 72% of the time: study

A recent preprint by Wang et al. highlights that AI agents are significantly more likely to select correctly described tools in an API, with a 72% success rate compared to a baseline of 20%. The study analyzed 10,831 MCP servers and found that 73% had repeated tool names, underscoring the importance of clear and compliant descriptions. The article provides practical advice on improving API descriptions, focusing on both a Markdown file for agent entry points and enhancing the completeness of OpenAPI specifications. AI

IMPACT Clearer API documentation and adherence to standards like OpenAPI will be crucial for effective AI agent integration and adoption.
