New tool audits MCP server security, finds widespread vulnerabilities

A new open-source tool called mcp-audit has been released to help users identify security vulnerabilities and inefficiencies in their MCP (Model-Centric Programming) server configurations. The tool, developed by alih552, scans local MCP setups for issues such as unauthenticated remote servers, plaintext secrets in configuration files, unpinned executable versions, overly broad filesystem access, and excessive token usage. Analysis of public MCP servers revealed significant security risks, with 41% lacking authentication and 36.7% being vulnerable to server-side request forgery. AI

IMPACT Enhances security and efficiency for developers using AI-integrated tools like Claude and Cursor.
