## Description

List all unique tags currently in use across Elastic Security cases via GET /api/cases/tags, or detection rules via GET /api/detection_engine/tags. Use this before tagging a case or rule so you reuse an existing tag instead of creating a near-duplicate (e.g. `incident-response` vs. `incident_response`). Cross-referenced by the `tags` parameter on **Create or Update Case**, **Create or Update Detection Rule**, and **Find Cases**. Example: calling with `objectType: "case"` returns `["council-jurassic-eval", "ransomware", "insider-threat"]`. [See the case tags documentation](https://www.elastic.co/docs/api/doc/kibana/operation/operation-getcasetagsdefaultspace) and the [rule tags documentation](https://www.elastic.co/docs/api/doc/kibana/operation/operation-readtags)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `objectType` | `string` | Yes | Whether to list tags used on cases or on detection rules. |

## Run it

**MCP**

```ts
import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js"
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(
  new URL("https://remote.mcp.pipedream.net/v3"),
  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${accessToken}`,
        "x-pd-project-id": process.env.PIPEDREAM_PROJECT_ID!,
        "x-pd-environment": "production",
        "x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
        "x-pd-app-slug": "elastic_security",
      },
    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
  name: "elastic_security-list-tags",
  arguments: {
    objectType: "Object Type",
  },
})
```

**TypeScript**

```ts
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "elastic_security-list-tags",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    elastic_security: { authProvisionId: "apn_xxxxxxx" },
    objectType: "Object Type",
  },
})

console.log(result)
```
