Quick question on the Smart Routing layer: when an upstream MCP server returns HTTP 402 (x402 payment required), does your proxy pass that status through so the client can run its own payment handler, or is it caught and flattened into a generic error upstream of Claude Code? The answer decides whether paid third-party MCP servers can negotiate through mcp.hosting at all, or whether everything has to be prepaid inside the account.

The constraint-first angle matters more than people give it credit for. A 1-bit screen and a handful of buttons forces students to stop hiding behind art and sound, and actually solve readability and mechanics. Honestly surprised more programs do not do this instead of dropping students into Unity on day one.

Seriously? Anything can be an equation now? Even emotions?

The response-side scanning gap is real. I've been building agent infrastructure and noticed the same blind spot. Most security tooling assumes the server is trusted once you've decided to connect, but MCP servers are arbitrary code endpoints, and prompt injection through tool responses is one of the harder attack vectors to defend against because the agent has to parse the response to do anything useful.

Curious about the regex approach at scale. With agents connecting to dozens of MCP servers simultaneously, how does latency overhead look in practice? The microsecond claim for individual checks makes sense, but the pattern set must grow fast as you add coverage for new attack vectors. At what point would you need to batch or cache pattern compilations?

The monitor mode default is smart for adoption. Did you find that teams who started in monitor mode actually switched to enforcement? In my experience with security proxies, monitor mode tends to become permanent.
