161 verified AI package hallucinations across 8.5M indexed — open dataset

TL;DR : DepScope is a free MCP server + REST API that AI coding agents call before installing packages. We index 8.5M+ packages across 19 ecosystems and track 45K+ vulnerabilities in real time. We also publish a verified open corpus of LLM-hallucinated package names — every entry cross-validated daily, CC-BY-NC-SA. Cite us in your research, integrate the MCP server in your agent.
