# Integrations

> Connect Zelto to your voice provider, notification channels, and issue tracker.

Integrations are configured per organization under **Settings → Integrations**.
Each one stores its credentials encrypted at rest; only the org members you've
added can decrypt them.

Start with a **voice provider** — that's how calls get into Zelto. Then wire up
notifications and issue tracking as you need them.

## Notifications

Where Zelto posts updates — and, in Slack, where you chat with it.

* [Slack](/docs/integrations/slack) — OAuth, per-channel routing.
* [Google Chat](/docs/integrations/google-chat) — incoming-webhook URL.

## Issue tracking

* [Linear](/docs/integrations/linear) — OAuth. File an issue straight from a
  finding, with a link back, and sync the finding's status as the issue moves.

## AI access

* [MCP](/docs/mcp) — give Claude Code, Cursor, Codex, and other editors
  read/write access to your Zelto data over Model Context Protocol. Same API key
  model as the [REST API](/api-reference/agents/list-agents).
