Story

Astrix analysis of 5,000+ open-source MCP servers: 53% rely on static API keys, only 8.5% implement OAuth. The MCP spec now supports OAuth 2.1 with PKCE and .well-known/oauth-protected-resource discovery. Five risk domains: authentication gaps, supply chain weaponization, privilege escalation via unscoped tokens, confused deputy attacks, and data exfiltration via trusted channels.

Builder action: Implement OAuth 2.1 with PKCE for all production MCP servers. Use short-lived tokens (5-30 min). Static API keys in MCP servers are the equivalent of storing passwords in plaintext. The tooling exists — adoption is the bottleneck.
