Show HN: The TypeScript Semantic Layer for ClickHouse

With hypequery there is no platform to adopt, no YAML sprawl. It runs where your app runs.

Key features:

- Define metrics once, reuse them everywhere: Declare dimensions and measures in one place and then pull from the same source of truth.

- Compiles to ClickHouse SQL: No service, no proxy, no extra runtime to deploy. It's a library that generates SQL and runs where your app runs.

- Multi-tenancy & Authentication ready: Cross-tenant queries are blocked at the query layer, helpers to plug into your existing auth.

- Agent-native: A dataset is a declared set of dimensions and measures, so it doubles as an allowlist. Includes an MCP server to hand an LLM a typed catalog to query.

- Runtime HTTP entry point: serve() exposes any dataset as an endpoint, so the same type-safe definitions back your dashboards and your API.
