An open standard, not a product

UKS is MIT-licensed and community-governed. It doesn't belong to any one implementer — the schema is the contract.

🧾

Evidence-graded, licensed, provenance-carrying

Every source carries an evidence grade, a clinical/trust status, and license fields — never collapsed to a boolean.

Evidence grading

Built for agents, not just humans

Layer E carries actions and agent instructions directly in the packet — the MCP server turns a packet into tools an agent can call.

MCP Server

🛠️

A real, working toolchain

A CLI validator, TypeScript and Python SDKs, and an MCP server — published, tested against a shared conformance corpus.

CLI (@uks/cli)

📜

On the standards track

A 30-day public comment period, then IANA media-type registration and a W3C Community Group submission.
