概要

What is OSV MCP Server?

OSV MCP Server is a Python-based MCP (Model Context Protocol) server that integrates Open Source Vulnerabilities (OSV) data and tools with AI assistants or large language models (LLMs). It is designed for developers and security researchers who want to query vulnerability information through an LLM interface.

How to use OSV MCP Server?

Clone the repository, create a virtual environment with uv, install dependencies using uv sync, and start the server with uv run vulns.py. For use with Claude Desktop, add the server configuration to claude_desktop_config.json specifying the uv command and path to the project.

Key features of OSV MCP Server

  • Exposes OSV vulnerability data via the MCP protocol
  • Provides a query_vulnerabilities tool for LLM invocation
  • Simple Python-based setup with uv package manager
  • Easily connectable to any MCP‑compatible AI assistant

Use cases of OSV MCP Server

  • Query open source vulnerabilities using natural language through an LLM
  • Integrate vulnerability lookup into AI‑driven security workflows
  • Enable developers to check dependency risks via conversational interface
  • Automate vulnerability research with LLM tool‑calling capabilities
