# Welcome to Katara

## What is Katara?

Katara is governed AI infrastructure that lets regulated organizations adopt AI while proving every interaction stays controlled, traceable, and compliant.

Katara sits between the AI tools your team already uses and the systems that need oversight. It applies policy, traceability, and access control so teams can keep working while governance evidence is produced along the way.

## Platform components

Katara is organized around four platform components:

* [**AI Knowledge Base**](/about/platform/ai-knowledge-base.md): keeps AI retrieval tied to approved sources, permissions, and policy.
* [**AI Gateway**](/about/platform/ai-gateway.md): keeps model traffic inside policy with access, routing, budget, and traceability controls.
* [**MCP Registry**](/about/platform/mcp-registry.md): manages approved MCP servers and tools so agents discover only the tools they are allowed to call.
* [**Shared Memory Layer**](/about/platform/shared-memory-layer.md): preserves useful context across sessions while scope, retention, and reuse stay governed.

Start with the [platform overview](/about/platform/platform.md), then open the component that matches the system you are evaluating.
