Val Town promotes OAuth Dynamic Client Registration to solve app-to-app connections

Val Town, a vibe coding platform, describes how it adopted Dynamic Client Registration (DCR), a little-known OAuth extension built into the MCP spec by Anthropic and OpenAI, to let apps automatically register as OAuth clients without manual developer portal work. Using this, Val Town built its MCP server so Claude and ChatGPT can authenticate into user accounts, and created a library called std/oauth that lets any app add 'Login with Val Town' in just two lines of code.

Val Town treats documentation as bait for AI agents, not just search engines

Val Town's team found that most new Pro subscribers in July were referred by AI systems, chiefly Claude, even before the company deliberately optimized its site for machine readers. They discovered that many of these referrals came not from clickable citations but from the models' training memory mentioning Val Town as plain text, meaning standard referral tracking like utm_source and Referer headers missed much of the actual traffic source.
