> Where to find your Segment Source Write Key and connect it to Nora.

Segment integrations let your agents send events into Segment for routing to downstream destinations (warehouses, analytics tools, marketing platforms). Nora stores the Source Write Key — Segment's write keys are **write-only** and have no validation endpoint.

## Where to apply for credentials

<Steps>
  <Step title="Pick a Source">
    Each Segment Source has its own write key. For server-side agents, create or pick a **Node.js** source.
  </Step>

  <Step title="Copy the Write Key">
    Source → Settings → **API Keys** → copy the Write Key.
  </Step>
</Steps>

## Connect in Nora

Paste the Write Key. Nora stores it without making any network call (Segment doesn't expose a validation endpoint for write keys). End-to-end verification happens when your agent sends its first event.

## MCP server

No official Segment MCP server today.
