Safety MCP is a Model Context Protocol (MCP) server that integrates with AI coding assistants to provide real-time package vulnerability intelligence during code generation. AI coding assistants such as Cursor, Windsurf, and GitHub Copilot lack the ability to identify outdated or vulnerable open-source packages when suggesting code. Safety MCP addresses this gap by connecting these assistants to Safety's vulnerability database, enabling them to check package versions for known vulnerabilities and recommend the latest secure versions in real time. Setup requires no account and takes approximately 30 seconds. Users add a JSON configuration snippet pointing to Safety's hosted MCP endpoint (mcp.safetycli.com) into their AI tool's MCP configuration file. Optional API key support is available for users with a Safety account. Once configured, the MCP server intercepts package-related suggestions from the AI assistant and queries Safety's vulnerability data to: - Verify whether a chosen package version is secure - Return the latest secure version of a package - Evaluate existing packages in a codebase for known vulnerabilities - Identify secure alternatives within the same major version Safety MCP supports any application that implements the Model Context Protocol standard, with explicit setup instructions provided for Cursor, Windsurf, GitHub Copilot, Claude Code, and Claude desktop. The tool is free to use without an account and is part of Safety's broader software supply chain security product suite, which also includes Safety CLI, Safety Firewall, and the Safety Platform.
