收藏资源简介:
PolicyLayer MCP服务器目录是一个风险分类的目录,包含通过公共注册表可访问的每个模型上下文协议(MCP)服务器。每个服务器公开的每个工具都使用基于动词的分类器和输入模式启发式方法分为六个风险类别之一。该目录是PolicyLayer研究报告《MCP安全状况—2026年5月》的基础数据集。数据集包含1,787个服务器和25,329个工具,分类于2026年5月,每月更新。数据集提供了服务器的详细信息(如名称、描述、工具数量、风险类别等)和工具的详细信息(如名称、描述、风险类别、严重性、置信度等)。数据集还涵盖了风险类别的定义和典型风险权重范围,以及数据集的覆盖范围、限制和使用注意事项。
The PolicyLayer MCP Server Catalogue is a risk-classified catalogue of every Model Context Protocol (MCP) server reachable through the public registries. Each tool exposed by each server is classified into one of six risk categories using a verb-based classifier with input-schema heuristics. The catalogue is the underlying dataset for PolicyLayers research report, *The State of MCP Security — May 2026*. The dataset includes 1,787 servers and 25,329 tools, classified in May 2026 and refreshed monthly. It provides detailed information on servers (e.g., name, description, tool count, risk categories) and tools (e.g., name, description, risk category, severity, confidence). The dataset also covers the definitions and typical risk weight ranges of risk categories, as well as the coverage, limitations, and usage notes of the dataset.
