SaberToolsResearch it. Standardize it. Serve it.

A platform for AI research, an open standard for packaging knowledge (UKS), and a living registry of verified, graded, licensed knowledge for agents.

Three layers, one ecosystem

SaberTools is best understood as three things that build on each other:

Layer	What it is	Who it's for
SaberTools	The research platform — an app that researches topics, organizes sources, and produces structured knowledge	Researchers, analysts, knowledge teams
UKS	The open standard the platform speaks — a portable JSON format for knowledge + agent actions	Developers, tool builders, implementers
The Registry	The shared, verified knowledge base built from UKS packets	AI agents, agent builders, integrators

The platform produces UKS packets. The standard defines what a packet is. The registry serves the best of them back — verified, graded, and license-checked — to any agent that asks.

Start where you are

"I want to research a topic and build a knowledge base" → SaberTools platform
"I want to validate or build UKS packets in my own app" → Getting Started
"I'm building an agent and want verified knowledge" → Query the Registry
"I want to understand or shape the format" → The Spec · Community

The ecosystem at a glance

bash

npm install -g @uks/cli
uks validate my-packet.uks.json     # Validate against the normative schema
uks serve   my-packet.uks.json      # Expose as an MCP tool for Claude
uks publish my-packet.uks.json      # Share in the public registry

Package	Install	Purpose
`@uks/cli`	`npm i -g @uks/cli`	Validate, convert, publish (the `uks` command)
`@uks/sdk`	`npm i @uks/sdk`	TypeScript builder + validator + registry client
`uks-sdk`	`pip install uks-sdk`	Python Pydantic models + validator
`@uks/mcp-server`	`npm i -g @uks/mcp-server`	MCP server — serve packets + query the registry from Claude
