# Agent.listSuspendedRuns()

**Added in:** `@mastra/core@1.43.0`

The `.listSuspendedRuns()` method uses workflow snapshot storage to find suspended agent runs, including runs awaiting [approval](https://mastra.ai/docs/agents/human-in-the-loop) for a tool call and runs paused by a tool that called `suspend()`. Storage-backed discovery continues to work after a server restart and across multiple server instances.

Pass the returned `runId` to [`resumeStream()`](https://mastra.ai/docs/agents/human-in-the-loop), `approveToolCall()`, or `declineToolCall()` to continue the run.

The filter contract mirrors the workflow run listing APIs (`listWorkflowRuns`), plus the agent-level `threadId` filter.

## Usage example

Discover the pending run for a conversation and continue it. Check `requiresApproval` to pick the right continuation: `approveToolCall()` / `declineToolCall()` for approval suspensions, `resumeStream()` with resume data for `suspend()`-based suspensions:

```typescript
const { runs } = await agent.listSuspendedRuns({
  threadId: 'thread-123',
  resourceId: 'user-456',
})

const run = runs[0]
const toolCall = run?.toolCalls[0]

if (run && toolCall) {
  const stream = toolCall.requiresApproval
    ? await agent.approveToolCall({ runId: run.runId, toolCallId: toolCall.toolCallId })
    : await agent.resumeStream({ name: 'San Francisco' }, { runId: run.runId })
}
```

## Parameters

**options** (`AgentListSuspendedRunsOptions`): Filters and pagination for scoping the results. (Default: `{}`)

**options.threadId** (`string`): Only return runs that belong to this memory thread.

**options.resourceId** (`string`): Only return runs that belong to this memory resource.

**options.fromDate** (`Date`): Only return runs created at or after this date.

**options.toDate** (`Date`): Only return runs created at or before this date.

**options.perPage** (`number`): Number of items per page. Pagination is applied when both perPage and page are provided; otherwise all matching runs are returned.

**options.page** (`number`): Zero-indexed page number.

## Returns

**result** (`Promise<AgentListSuspendedRunsResult>`): A promise that resolves to the matching runs and the total count before pagination.

```typescript
interface AgentListSuspendedRunsResult {
  runs: AgentRun[]
  /** Total number of matching runs, before pagination */
  total: number
}

interface AgentRun {
  /** Run ID accepted by resumeStream(), approveToolCall(), and declineToolCall() */
  runId: string
  status: 'suspended'
  threadId?: string
  resourceId?: string
  /** When the run suspended */
  suspendedAt: Date
  /** Suspended tool calls awaiting approval or resume data */
  toolCalls: AgentRunToolCall[]
}

interface AgentRunToolCall {
  toolCallId?: string
  toolName?: string
  /** Arguments the model supplied (approval suspensions only) */
  args?: unknown
  /** True when the run is waiting on a tool-call approval */
  requiresApproval: boolean
  /** The tool-defined suspend payload when the tool called suspend() */
  suspendPayload?: unknown
}
```

## Discovery scope

Results are scoped to the agent you call `listSuspendedRuns()` on because snapshots persist the owning agent's id. Runs started by other agents on the same Mastra instance aren't returned. In [supervisor setups](https://mastra.ai/docs/agents/human-in-the-loop), the supervisor sees its outer run to resume, while a subagent's inner run is visible only from the subagent itself. Filter by `threadId` and `resourceId` to limit results to one conversation.

Run snapshots are only persisted while a run is waiting on input and are deleted when it finishes, so suspended runs are the only runs discoverable from storage. Suspended runs only survive restarts when the Mastra instance has a persistent [storage provider](https://mastra.ai/docs/storage) configured. With the default in-memory store, snapshots are lost on restart.

The `threadId` and `resourceId` filters are pushed down to the storage query where the adapter supports it. `@mastra/pg` and `@mastra/libsql` narrow matching runs inside the database instead of loading every suspended snapshot, and the in-memory store filters its in-memory records. Other storage adapters apply these filters in-process after fetching. Results are identical either way.
