# List Fallback LLMs

> Use the list_fallback_llms MCP tool on the DialNexa remote MCP server.

<span data-api-safety-label="read-only"><Badge color="gray" size="sm" shape="pill">Read only</Badge></span>

Returns the LLMs eligible to be configured as an agent’s fallback model (used if the primary LLM fails). Use when the user asks what fallback LLM options exist.

## Parameters

| Name    | Type     | Required | Description                          |
| ------- | -------- | -------- | ------------------------------------ |
| `page`  | `string` | No       | Page number, default 1               |
| `limit` | `string` | No       | Results per page, default 10, max 50 |

## Before you call

* Connect and initialize the MCP client with OAuth or an API key for the intended workspace.
* This tool has no required arguments.

## Example MCP request

Send `tools/call` after your client completes MCP initialization. Replace placeholder values with IDs and inputs from your workspace. For object and array parameters, follow the nested requirements in the parameter description instead of treating an empty value as complete.

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_fallback_llms",
    "arguments": {}
  }
}
```

The server returns one text content block. Parse `content[0].text` as JSON when the tool succeeds. See [MCP responses and errors](/docs/mcp-tools/errors) for the full envelope and failure behavior.

## Verify the result

Confirm the response is not marked `isError`, parse `content[0].text` as JSON, and verify that returned IDs and workspace data match the request.

## Retry safety

This tool does not change workspace data. Retrying after a transient transport failure is safe.
