# Integrations & Connectors

> Discover and call third-party API connectors and custom MCP servers.

### Discover API Connectors `discover_api_connectors`

See which third-party data connectors are available to your organization and what they can do. Simon uses this to find the right source before pulling data from a connected system.

| Parameter            | Type     |
| -------------------- | -------- |
| `query` **required** | `string` |
| `category` *opt*     | `string` |

### Execute API Connector Action `execute_api_connector_action`

Run an action against a connected third-party system to fetch or update data. Simon uses this to work directly with your connected systems on your behalf.

| Parameter                   | Type      |
| --------------------------- | --------- |
| `action_id` **required**    | `string`  |
| `connector_id` **required** | `string`  |
| `arguments` *opt*           | `object`  |
| `confirmed` *opt*           | `boolean` |

### Execute Custom MCP Tool `execute_custom_mcp_tool`

Run a tool on one of your organization's custom integrations. Simon uses this to act within connected systems, asking for your confirmation when an action needs approval.

| Parameter                | Type      |
| ------------------------ | --------- |
| `provider` **required**  | `string`  |
| `tool_name` **required** | `string`  |
