# list_apps

Returns workspace apps, configuration, receipt observations, history coverage, contact counts and uninstall-watch information.

## Purpose

The workspace's Shopify apps with integration observations and history coverage: receipt recency, contact capture configured?, uninstall watches registered, contact coverage. Call FIRST when asked to connect/integrate an app with Crust, or to check integration health.

## Credentials and scope

Owner workspace credential. The credential determines tool visibility. For tools with appId, use the HeyCrust app UUID from list_apps; the dashboard app selector does not supply MCP arguments for you.

## Inputs

This tool accepts an empty argument object.

## Example request

The identifiers and merchant are fictional. Replace them with records returned for your own workspace; this example is schema-checked, not a promise that the fictional record exists.

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_apps",
    "arguments": {}
  }
}
```

POST this JSON to `https://heycrust.com/api/mcp` with `Content-Type: application/json` and `Authorization: Bearer <YOUR_CREDENTIAL>`. The tool result normally contains JSON encoded as text in `result.content`; inspect JSON-RPC errors and `result.isError` before using it.

## Result

Returns workspace apps, configuration, receipt observations, history coverage, contact counts and uninstall-watch information. Ever-observed legacy flags are not current source-health proof.

## Effects and verification

Reads existing records or definitions. It does not create a payment or send a message. Verify the returned app/merchant identity and source coverage before interpreting the result.

## Troubleshooting

A missing tool can mean that the credential lacks its catalog or required scopes. Invalid arguments are different from unavailable source data or a record outside the workspace. A handler can return a business error even when the argument schema is valid. Read [MCP overview](/docs/mcp) and [Help](/docs/help).
