概要

What is MCP Server For OSV?

MCP Server For OSV is a lightweight MCP server that wraps the OSV (Open Source Vulnerabilities) Database API, letting you query CVEs for specific packages, find affected and fixed versions, and list supported ecosystems. It is designed for developers and security researchers who need vulnerability data inside AI-powered tools like Cursor and Claude Desktop.
