MCP Registry Permission-Surface Metadata Atlas

A reproducible public-source metadata atlas of the official Model Context Protocol (MCP) Registry. The packet includes a 10,856-row latest-version registry snapshot, a 32,834-row all-version registry supplement, derived permission-surface signal labels, evidence-debt indicators, and code for rebuilding, validating, and summarizing the atlas. The dataset is intended for research on registry metadata quality, AI-agent tool-permission discoverability, and public MCP ecosystem measurement. It is registry-metadata analysis, not a vulnerability scan or certification of any server.
