AI-analyzed exploit summary This repository provides a Python-based security scanner for Model Context Protocol (MCP) configurations, specifically detecting misconfigurations and vulnerabilities such as CVE-2025-68143 (authentication gaps in MCP servers). It analyzes JSON configuration files for command injection risks, exposed endpoints, credential leakage, and other security issues without exploiting them.

Description

Model Context Protocol Servers is a collection of reference implementations for the model context protocol (MCP). In mcp-server-git versions prior to 2025.9.25, the git_init tool accepted arbitrary filesystem paths and created Git repositories without validating the target location. Unlike other tools which required an existing repository, git_init could operate on any directory accessible to the server process, making those directories eligible for subsequent git operations. The tool was removed entirely, as the server is intended to operate on existing repositories only. Users are advised to upgrade to 2025.9.25 or newer to remediate this issue.
