OSV

OSV is a lightweight Model Context Protocol (MCP) server that interfaces with the OSV Database API. It provides tools to query vulnerability information, including listing CVE IDs for a specific package (optionally with a specific version and ecosystem), querying for affected versions of a package given a CVE ID, and querying for fixed versions given a CVE ID. Additionally, it provides an endpoint to retrieve all currently supported ecosystems. It is designed to be used with AI coding assistants like Cursor and Claude.
