Authgent Scanned OAuth Across 30 Production MCP Servers; the Author Says Only One Earned an A

The Authgent open-source project claims to have evaluated OAuth implementations across 30 production MCP servers and awarded an A grade to only one. If supported by reproducible tests, the result would highlight potentially widespread authorization weaknesses in the Model Context Protocol ecosystem. However, the supplied Hacker News metadata contains no grading rubric, server list, test procedure, vulnerability breakdown, or independent validation. The repository should therefore be read as the primary evidence, while the headline statistic remains an author-reported claim rather than an established ecosystem-wide measurement.
