MCP2MCP Proxy Gateway
What was going on
Every enterprise tool I touched had its own OAuth. Teams were writing bespoke integrations for every new MCP server — days of manual work, every time. Nobody was fixing it at the right layer.
What I figured out
If you build a proxy that handles RFC-compliant OAuth for any remote server, the integration cost drops to 'give me the URL.' That's the right abstraction. I went all-in on it: four discovery paths (RFC 6750, 9728, 8414, 8707) with Dynamic Client Registration as a fallback.
What happened
38+ servers in production, zero manual onboarding ops. Tool hallucinations became impossible — not because we filter bad calls, but because they can't happen by construction. That distinction matters.
