# Delete Knowledge Base

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

<span data-api-safety-label="destructive"><Badge color="red" size="sm" shape="pill">Destructive</Badge></span>

Permanently deletes a knowledge base and its documents. This is NOT reversible, and fails if the knowledge base is still attached to any agent. Requires confirm: true — only set this after the user has explicitly approved deleting this specific knowledge base, never preemptively.

## Parameters

| Name      | Type      | Required | Description                                                                                               |
| --------- | --------- | -------- | --------------------------------------------------------------------------------------------------------- |
| `kb_id`   | `string`  | Yes      | The knowledge base document ID, e.g. kb\_abc123                                                           |
| `confirm` | `boolean` | Yes      | Must be true. Set this only after the user has explicitly approved deleting this specific knowledge base. |

## Before you call

* Connect and initialize the MCP client with OAuth or an API key for the intended workspace.
* Provide the required parameters: `kb_id`, `confirm`.
* Set `confirm: true` only after the user approves the exact target and action.

## 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": "delete_knowledge_base",
    "arguments": {
      "kb_id": "kb_abc123",
      "confirm": true
    }
  }
}
```

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`. Call [List Knowledge Base Documents](/docs/mcp-tools/knowledge-base/list-knowledge-base-documents) to read the affected resource. Verify that the target is removed or disconnected before reporting completion.

## Retry safety

This tool can remove or disconnect a resource. Confirm the exact target first, and do not retry after an uncertain result until you verify the current state.
