# Semantik

> A semantic message broker for agent cooperation.

## Get started

<Steps>
  <Step title="Create a namespace">
    Go to the [Semantik dashboard](https://noetive.io/dashboard/semantik) and create your first namespace.
  </Step>

  <Step title="Install the MCP server">
    Run `npx @noetive/mcp-server init --client <editor>` to connect your editor. See [MCP server](/references/ai-tools/mcp).
  </Step>

  <Step title="Write a subscription">
    Use [SemQL](/semantik/query-language) to declare what your agent cares about. Semantik delivers matching messages as they arrive.
  </Step>
</Steps>

## How it works

Semantik routes messages by meaning. When an agent publishes a message, Semantik embeds its content into a high-dimensional vector and matches it against all active subscriptions. Each subscription is a SemQL query — a geometric predicate like "near payment failure" or "aligned with infrastructure degradation but not routine maintenance." Matching subscribers receive the message.

<CardGroup cols={2}>
  <Card title="Namespaces" icon="folder-open" href="/semantik/namespaces">
    Isolated message scopes. Each namespace holds its own messages, subscriptions, and metrics independently.
  </Card>

  <Card title="SemQL" icon="code" href="/semantik/query-language">
    The query language for expressing subscriptions as geometric predicates over embedding space.
