Introducing Amazon Bedrock AgentCore Gateway: Remodeling enterprise AI agent software improvement

To meet their duties, AI Brokers want entry to numerous capabilities together with instruments, knowledge shops, immediate templates, and different brokers. As organizations scale their AI initiatives, they face an exponentially rising problem of connecting every agent to a number of instruments, creating an M×N integration drawback that considerably slows improvement and will increase complexity.

Though protocols resembling Mannequin Context Protocol (MCP) and Agent2Agent (A2A) have emerged to handle interoperability, implementing these options requires substantial engineering effort. Organizations should construct MCP servers, convert present APIs, handle infrastructure, construct clever instruments discovery, and implement safety controls, all that whereas sustaining these integrations over time as protocols quickly evolve and new main variations are launched. As deployments develop to a whole lot of brokers and hundreds of instruments, enterprises want a extra scalable and manageable answer.

Introducing Amazon Bedrock AgentCore Gateway

We’re excited to announce Amazon Bedrock AgentCore Gateway, a completely managed service that revolutionizes how enterprises join AI brokers with instruments and providers. AgentCore Gateway serves as a centralized software server, offering a unified interface the place brokers can uncover, entry, and invoke instruments.

Constructed with native assist for the MCP, Gateway permits seamless agent-to-tool communication whereas abstracting away safety, infrastructure, and protocol-level complexities. This service gives zero-code MCP software creation from APIs and AWS Lambda capabilities, clever software discovery, built-in inbound and outbound authorization, and serverless infrastructure for MCP servers. You’ll be able to give attention to constructing clever agent experiences relatively than managing connectivity with instruments and providers. The next diagram illustrates the AgentCore Gateway workflow.

Key capabilities of Amazon Bedrock AgentCore Gateway

The Amazon Bedrock AgentCore Gateway introduces a complete set of capabilities designed to revolutionize software integration for AI brokers. At its core, Gateway presents highly effective and safe API integration performance that transforms present REST APIs into MCP servers. This integration helps each OpenAPI specs and Smithy fashions, so organizations can seamlessly convert their enterprise APIs into MCP-compatible instruments. Past API integration, Gateway gives built-in assist for Lambda capabilities so builders can join their serverless computing sources as instruments with outlined schemas. Gateway gives the next key capabilities:

• Safety Guard – Manages OAuth authorization so solely legitimate customers and brokers can entry instruments and sources. We are going to dive deeper into safety within the following part.
• Translation – Converts agent requests utilizing protocols resembling MCP into API requests and Lambda invocations, assuaging the necessity to handle protocol integration or model assist.
• Composition – Combines a number of APIs, capabilities, and instruments right into a single MCP endpoint for streamlined agent entry.
• Goal extensibility – An AgentCore gateway is a central entry level that serves as a unified interface for AI brokers to find and work together with instruments. It handles authentication, request routing, and protocol translation between MCP and your APIs. Every gateway can handle a number of targets. A goal represents a backend service or group of APIs that you simply wish to expose as instruments to AI brokers. Targets may be AWS Lambda capabilities, OpenAPI specs, or Smithy fashions. Every goal can expose a number of instruments, and Gateway routinely handles the conversion between MCP and the goal’s built-in protocol. Gateway helps streamable http transport.
• Infrastructure Supervisor – As a completely managed service, Gateway removes the burden of infrastructure administration from organizations. It gives complete infrastructure with built-in safety features and sturdy observability capabilities. Groups now not want to fret about internet hosting issues, scaling points, or sustaining the underlying infrastructure. The service routinely handles these elements, offering dependable efficiency and seamless scaling as demand grows.
• Semantic Instrument Choice – Clever software discovery represents one other core functionality of Gateway. As organizations scale to a whole lot or hundreds of instruments, discovering the suitable software turns into more and more difficult for AI brokers.

Gateway addresses these challenges by offering a particular built-in software named 'x_amz_bedrock_agentcore_search' that may be accessed utilizing the usual MCP instruments and name operation.

Safety and authentication

Gateway implements a complicated dual-sided safety structure that handles each inbound entry to Gateway itself and outbound connections to focus on providers.

For inbound requests, Gateway follows the MCP authorization specification, utilizing OAuth-based authorization to validate and authorize incoming software calls. Gateway capabilities as an OAuth useful resource server. This implies it might probably work with the OAuth Id Supplier your group would possibly use–whether or not that’s Amazon Cognito, Okta, Auth0, or your individual OAuth supplier. While you create a gateway, you’ll be able to specify a number of permitted consumer IDs and audiences, supplying you with granular management over which purposes and brokers can entry your instruments. The Gateway validates incoming requests towards your OAuth supplier, supporting each authorization code move (3LO) and consumer credentials move (2LO, generally used for service-to-service communication).

The outbound safety mannequin is equally versatile however varies by goal kind:

For AWS Lambda and Smithy mannequin targets, AgentCore Gateway makes use of AWS Id and Entry Administration (IAM) based mostly authorization. The gateway assumes an IAM function you configure, which might have exactly scoped permissions for every goal service. This integrates easily with present AWS safety practices and IAM insurance policies.

For OpenAPI targets (REST APIs), Gateway helps two authentication strategies:

1. API key – You’ll be able to configure the important thing to be despatched in both headers or question parameters with customizable parameter names
2. OAuth token for 2LO – For outbound OAuth authentication to focus on APIs, Gateway helps two-legged OAuth (2LO) consumer credentials grant kind, enabling safe machine-to-machine communications with out consumer interplay

Credentials are securely managed via AgentCore Id’s useful resource credentials supplier. Every goal is related to precisely one authentication configuration, facilitating clear safety boundaries and audit trails. AgentCore Id handles the advanced safety equipment whereas presenting a clear, easy interface to builders. You configure safety one time throughout setup, and Gateway handles the token validation, outbound token caching (via AgentCore Id), and safe communication from there.

Get began with Amazon Bedrock AgentCore Gateway

You’ll be able to create gateways and add targets via a number of interfaces:

The next sensible examples and code snippets display the method of establishing and utilizing Amazon Bedrock AgentCore Gateway.

Create a gateway

To create a gateway, use Amazon Cognito for inbound auth utilizing the AWS Boto3:

gateway_client = boto3.consumer('bedrock-agentcore-control')
auth_config = {
    "customJWTAuthorizer": { 
        "allowedClients": '‘, # Shopper MUST match with the ClientId configured in Cognito.
        "discoveryUrl": ''
    }
}
create_response = gateway_client.create_gateway(identify="DemoGateway",
    roleArn = '' # The IAM Function will need to have permissions to create/checklist/get/delete Gateway 
    protocolType="MCP",
    authorizerType="CUSTOM_JWT",
    authorizerConfiguration=auth_config, 
    description='Demo AgentCore Gateway'
)
# Values with < > must be changed with actual values

Right here is the reference to management aircraft and knowledge aircraft APIs for Amazon Bedrock AgentCore.

Create gateway targets

Create a goal for an present API utilizing OpenAPI specification with API key as an outbound auth:

# Create outbound credentials supplier in AgentCore Id
acps  boto3client(service_name"bedrock-agentcore-control")

responseacpscreate_api_key_credential_provider(
identify"APIKey",
apiKey"

Create a target for a Lambda function:

# Define the lambda target with tool schema. Replace the AWS Lambda function ARN below
lambda_target_config = {
  "mcp": {
    "lambda": {
      "lambdaArn": "",
      "toolSchema": {
        "inlinePayload": [
          {
            "name": "get_order_tool",
            "description": "tool to get the order",
            "inputSchema": {
              "type": "object",
              "properties": {
                "orderId": {
                  "type": "string"
                }
              },
              "required": [
                "orderId"
              ]}}]}}}}

# Create outbound auth config. For AWS Lambda perform, its at all times IAM.
credential_config = [ 
    {
        "credentialProviderType" : "GATEWAY_IAM_ROLE"
    }
]

# Add AWS Lambda goal to the gateway
targetname="LambdaUsingSDK"
response = gateway_client.create_gateway_target(
    gatewayIdentifier=gatewayID,
    identify=targetname,
    description='Lambda Goal utilizing SDK',
    targetConfiguration=lambda_target_config,
    credentialProviderConfigurations=credential_config)

Use Gateway with completely different agent frameworks

from strands import Agent
import logging

def create_streamable_http_transport():
    return streamablehttp_client(gatewayURL,headers={"Authorization": f"Bearer {token}"})

consumer = MCPClient(create_streamable_http_transport)

with consumer:
    # Name the listTools 
    instruments = consumer.list_tools_sync()
    # Create an Agent with the mannequin and instruments
    agent = Agent(mannequin=yourmodel,instruments=instruments) ## you'll be able to change with any mannequin you want
    # Invoke the agent with the pattern immediate. It will solely invoke  MCP listTools and retrieve the checklist of instruments the LLM has entry to. The beneath doesn't really name any software.
    agent("Hello , are you able to checklist all instruments out there to you")
    # Invoke the agent with pattern immediate, invoke the software and show the response
    agent("Examine the order standing for order id 123 and present me the precise response from the software")

Use Gateway with LangChain integration:

from langchain_mcp_adapters.consumer import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain.chat_models import init_chat_model

consumer = MultiServerMCPClient(
        {
            "healthcare": {
                "url": gateway_endpoint,
                "transport": "streamable_http",
                "headers":{"Authorization": f"Bearer {jwt_token}"}
            }
        }
    )
 agent = create_react_agent(
        LLM, 
        instruments, 
        immediate=systemPrompt
 )

Implement semantic search

You’ll be able to choose in to semantic search when making a gateway. It routinely provisions a robust built-in software known as x_amz_bedrock_agentcore_search that permits clever software discovery via pure language queries. Use the output of the search software rather than MCP’s checklist operation for scalable and performant software discovery. The next diagram illustrates how you need to use the MCP search software.

To allow semantic search, use the next code:

 # Allow semantic search of instruments
    search_config = {
        "mcp": {"searchType": "SEMANTIC", "supportedVersions": ["2025-03-26"]}
    }
    # Create the gateway
    response = agentcore_client.create_gateway(
        identify=gateway_name,
        roleArn=gateway_role_arn,
        authorizerType="CUSTOM_JWT",
        description=gateway_desc,
        protocolType="MCP",
        authorizerConfiguration=auth_config,
        protocolConfiguration=search_config,
    )
def tool_search(gateway_endpoint, jwt_token, question):
    toolParams = {
        "identify": "x_amz_bedrock_agentcore_search",
        "arguments": {"question": question},
    }
    toolResp = invoke_gateway_tool(
        gateway_endpoint=gateway_endpoint, jwt_token=jwt_token, tool_params=toolParams
    )
    instruments = toolResp["result"]["structuredContent"]["tools"]
    return instruments
