# List available prompts in an AgentCore gateway
To list all available prompts that an AgentCore gateway provides, make a POST request to the gateway’s MCP endpoint and specify `prompts/list` as the method in the request body:
**Example**
```
POST /mcp HTTP/1.1
Host: ${GatewayEndpoint}
Accept: application/json, text/event-stream
Content-Type: application/json
Authorization: ${Authorization header}
MCP-Protocol-Version: ${McpProtocolVersion}
${RequestBody}
```
On version `2026-07-28`, each request carries the `MCP-Protocol-Version` header, the `Mcp-Method` request-metadata header, and the `_meta` version fields in the body.
```
POST /mcp HTTP/1.1
Host: ${GatewayEndpoint}
Accept: application/json, text/event-stream
Content-Type: application/json
Authorization: ${Authorization header}
MCP-Protocol-Version: 2026-07-28
Mcp-Method: prompts/list
${RequestBody}
```
**Note**
The gateway accepts only the MCP protocol versions listed in the `supportedVersions` field of its `protocolConfiguration.mcp` configuration. To use version `2026-07-28`, make sure that your gateway’s `supportedVersions` includes it. You can change the supported versions with the [UpdateGateway](https://docs.aws.amazon.com/bedrock-agentcore-control/latest/APIReference/API_UpdateGateway.html) API.
Replace the following values:
+ `${GatewayEndpoint}` – The URL of the gateway, as provided in the response of the [CreateGateway](https://docs.aws.amazon.com/bedrock-agentcore-control/latest/APIReference/API_CreateGateway.html) API.
+ `${Authorization header}` – The authorization credentials from the identity provider when you set up [inbound authorization](gateway-inbound-auth.md).
+ `${McpProtocolVersion}` – The MCP protocol version for the request, such as `2025-11-25`. The version must be one that your gateway supports.
+ `${RequestBody}` – The JSON payload of the request body, as specified in [Listing prompts](https://modelcontextprotocol.io/specification/2025-06-18/server/prompts#listing-prompts) in the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/docs/getting-started/intro) . Include `prompts/list` as the `method`. On version `2026-07-28`, also include the `_meta` version fields in `params`.
**Note**
For a list of optionally supported parameters for `prompts/list` , see the `params` object in the request body at [Prompts](https://modelcontextprotocol.io/specification/2025-06-18/server/prompts) in the [Model Context Protocol documentation](https://modelcontextprotocol.io/specification/2025-06-18) . At the top of the page next to the search bar, you can select the MCP version whose documentation you want to view. Make sure that the version is one [supported by Amazon Bedrock AgentCore](gateway-using.md).
The response returns a list of available prompts with their names, descriptions, and arguments.
## Code samples for listing prompts
To see examples of listing available prompts in the gateway, select one of the following methods:
**Example**
Set the `MCP-Protocol-Version` header to a version that your gateway supports.
```
import requests
import json
def list_prompts(gateway_url, access_token):
headers = {
"Content-Type": "application/json",
"Authorization": f"Bearer {access_token}",
"MCP-Protocol-Version": "2025-11-25"
}
payload = {
"jsonrpc": "2.0",
"id": "list-prompts-request",
"method": "prompts/list"
}
response = requests.post(gateway_url, headers=headers, json=payload)
return response.json()
# Example usage
gateway_url = "https://${GatewayEndpoint}/mcp" # Replace with your actual gateway endpoint
access_token = "${AccessToken}" # Replace with your actual access token
prompts = list_prompts(gateway_url, access_token)
print(json.dumps(prompts, indent=2))
```
On version `2026-07-28`, add the `MCP-Protocol-Version` and `Mcp-Method` headers, and include the `_meta` version fields in the request body. Your gateway’s `supportedVersions` must include `2026-07-28`.
```
import requests
import json
def list_prompts(gateway_url, access_token):
headers = {
"Content-Type": "application/json",
"Authorization": f"Bearer {access_token}",
"MCP-Protocol-Version": "2026-07-28",
"Mcp-Method": "prompts/list"
}
payload = {
"jsonrpc": "2.0",
"id": "list-prompts-request",
"method": "prompts/list",
"params": {
"_meta": {
"io.modelcontextprotocol/protocolVersion": "2026-07-28",
"io.modelcontextprotocol/clientInfo": {"name": "my-agent", "version": "1.0.0"},
"io.modelcontextprotocol/clientCapabilities": {}
}
}
}
response = requests.post(gateway_url, headers=headers, json=payload)
return response.json()
# Example usage
gateway_url = "https://${GatewayEndpoint}/mcp" # Replace with your actual gateway endpoint
access_token = "${AccessToken}" # Replace with your actual access token
prompts = list_prompts(gateway_url, access_token)
print(json.dumps(prompts, indent=2))

**Note**
Prompt names are prefixed with the target name using the format `{targetName}___{promptName}`. This is the same naming convention used for tools. For more information, see [Tool naming conventions](gateway-tool-naming.md).
