Proximity is a new open-source tool that scans Model Context Protocol (MCP) servers. It identifies the prompts, tools, and resources that a server makes available, and it can evaluate how those elements might introduce security risks. The tool also work with NOVA, a rule engine that checks for issues such as prompt injection or jailbreak attempts.
