# Cari alat di AgentCore gateway Anda dengan kueri bahasa alami
Jika Anda mengaktifkan pencarian semantik untuk gateway Anda saat Anda membuatnya, Anda dapat memanggil `x_amz_bedrock_agentcore_search` alat untuk mencari alat di gateway Anda dengan kueri bahasa alami. Pencarian semantik sangat berguna ketika Anda memiliki banyak alat dan perlu menemukan yang paling tepat untuk kasus penggunaan Anda. Untuk mempelajari cara mengaktifkan penelusuran semantik selama pembuatan gateway, lihat [Membuat gateway Amazon Bedrock AgentCore ](gateway-create.md).
Untuk mencari alat menggunakan AgentCore alat ini, buat permintaan POST berikut dengan `tools/call` metode ke titik akhir MCP gateway:
```
POST /mcp HTTP/1.1
Host: ${GatewayEndpoint}
Content-Type: application/json
Authorization: ${Authorization header}
{
"jsonrpc": "2.0",
"id": "${RequestName}",
"method": "tools/call",
"params": {
"name": "x_amz_bedrock_agentcore_search",
"arguments": {
"query": ${Query}
}
}
}
```
Ganti nilai-nilai berikut:
+ `${GatewayEndpoint}`— URL gateway, seperti yang disediakan dalam respons [CreateGateway](https://docs.aws.amazon.com/bedrock-agentcore-control/latest/APIReference/API_CreateGateway.html)API.
+ `${Authorization header}`[- Kredensi otorisasi dari penyedia identitas saat Anda mengatur otorisasi masuk.](gateway-inbound-auth.md)
+ `${RequestName}`Sebuah nama untuk permintaan.
+ `${Query}`— Kueri bahasa alami untuk mencari alat.
Respons mengembalikan daftar alat yang relevan dengan kueri.
## Contoh kode untuk pencarian alat
Untuk melihat contoh penggunaan kueri bahasa alami untuk menemukan alat di gateway, pilih salah satu metode berikut:
**Example**

```

"params": {

return response.json()
# Example usage
gateway_url = "https://${GatewayEndpoint}/mcp" # Replace with your actual gateway endpoint
access_token = "${AccessToken}" # Replace with your actual access token
results = search_tools(gateway_url, access_token, "find order information")
print(json.dumps(results, indent=2))
