# Introduction

> Corsair lets your app integrate with hundreds of services through chat agents or deterministic UI actions.

Corsair is an open source product that lets an app integrate with anything. Hundreds of integrations are available — Gmail, Slack, Google Calendar, Microsoft Teams, GitHub, Linear, and more.

For the full list, see [api.corsair.dev/md/integrations](https://api.corsair.dev/md/integrations).

<Note>
  **Setting up with a coding agent?** Use [Agent setup](/app/agent-setup) — clarify intent, provision via the SDK, ask when instance/tenant/plugin choice is unclear.
</Note>

## Two ways to use Corsair

You can use Corsair in chat or a UI (or both). Each works in single-tenant or multi-tenant setups.

| Mode                   | What it is                                                                                       | Best for                                                 |
| ---------------------- | ------------------------------------------------------------------------------------------------ | -------------------------------------------------------- |
| **Agentic (chat)**     | An MCP server that exposes your enabled integrations as tools for coding agents and AI harnesses | Cursor, Claude Code, Vercel AI SDK, OpenAI Agents        |
| **Deterministic (UI)** | Execute catalog operations directly from your backend                                            | Workflow automation, buttons like "Send calendar invite" |

## Install

```bash theme={null}
