Propose adding a counterparty to the agent's envelope allowlist. Per the multisig allowlist gate, allowlist mutations are multisig-proposal based — this tool enqueues the proposal; the principal approves via the web dashboard.

## Auth

Caller's grant must include the `beneficiary:write` scope. Grants whose scope set is a superset of the required scope are accepted.

## Response examples

Success — proposal enqueued for principal approval:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "proposal_id": "c3d4e5f6-a7b8-9012-cdef-123456789012",
    "status": "pending_principal_approval",
    "enqueued_at": "2026-05-04T09:15:00Z"
  }
}
```

Auto-approved (policy permits the counterparty without human sign-off):

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "proposal_id": "c3d4e5f6-a7b8-9012-cdef-123456789012",
    "status": "auto_approved",
    "enqueued_at": "2026-05-04T09:15:00Z"
  }
}
```

Missing scope:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32001,
    "message": "grant does not include scope beneficiary:write",
    "data": { "reason_id": "insufficient_scope" }
  }
}
```
