# Connections

> Connecting external tools: OAuth integrations, per-tool controls, and MCP access.

Connections power your agents and chat with real tools: email, calendars, CRMs, spreadsheets, and any MCP server. Connections are **personal** — each user connects their own accounts, and agents run with their owner's connections.

**Where:** Sidebar › Settings › Integrations › **Connections** (route `/connections`). Available to every user.

The page header offers **Sync All** (refresh the status of all your connections) and **Connect Integration** (jumps to the Marketplace tab). Four tabs:

## Connected

Your active integrations, with stat cards (Total Connections, Available Toolkits). Each connection card shows the app logo, name, status (**Connected**, or connecting / expired / revoked / paused), the connect date and last use, plus:

| Control                   | What it does                                                                         |
| ------------------------- | ------------------------------------------------------------------------------------ |
| **Pause / Resume** switch | Temporarily stop agents and chat from using this connection without disconnecting it |
| **Sync**                  | Refresh this connection's status                                                     |
| **Settings**              | View connection details (provider, account, dates)                                   |
| **Disconnect**            | Remove the connection entirely (asks for confirmation)                               |

Which of a connection's individual actions an agent may use is granted **per agent** under Agents › Skills & Tools › Connected Tools — not here.

## Marketplace

Browse 200+ integrations: search, filter by category, and sort by name or tool count. Each card shows the app, its description, and its tool count. Click **Connect** — the OAuth sign-in opens in a new tab, and the connection syncs automatically when you return (*"Connection synced — new connection picked up automatically"*).

## OpenRouter

Your AI-provider account at a glance: total spent, limit, remaining, and last sync, with **Sync now** and a link to the OpenRouter dashboard for per-model breakdowns.

## MCP

Model Context Protocol servers give your agents self-describing tools with zero custom code.

### MCP Servers

Click **Add MCP server** and fill in:

| Field                        | Notes                                                      |
| ---------------------------- | ---------------------------------------------------------- |
| Label                        | Display name                                               |
| Server URL                   | The MCP endpoint                                           |
| Auth header name             | Default `X-API-KEY`                                        |
| API key                      | Optional for public servers                                |
| Transport                    | HTTP (streamable) or SSE                                   |
| Scope *(agency admins only)* | This Company, or Whole Provider (all companies inherit it) |

Each server card has an enable switch, a **Probe** button (verifies reachability and counts its tools), a **"Require approval for writes"** switch — write-capable tools then go through your approval flow — and **Disconnect**. Grant a server to an agent under Agents › Skills & Tools › MCP Servers.

### Vertical Layer

One optional slot for your provider's domain-intelligence feed (industry data and know-how served over MCP). Admins can connect it in **Hosted** or **Bring-your-own MCP** mode; a contract probe validates the connection. If you are not an admin and no vertical is connected, ask your provider admin.
