Introducing Amazon Bedrock AgentCore Gateway: Remodeling enterprise AI agent instrument growth

To satisfy their duties, AI Brokers want entry to varied capabilities together with instruments, information 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 growth and will increase complexity.

Though protocols resembling Model Context Protocol (MCP) and Agent2Agent (A2A) have emerged to handle interoperability, implementing these options requires substantial engineering effort. Organizations should construct MCP servers, convert current 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 lots of of brokers and hundreds of instruments, enterprises want a extra scalable and manageable resolution.

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 companies. AgentCore Gateway serves as a centralized instrument server, offering a unified interface the place brokers can uncover, entry, and invoke instruments.

Constructed with native assist for the MCP, Gateway allows seamless agent-to-tool communication whereas abstracting away safety, infrastructure, and protocol-level complexities. This service supplies zero-code MCP instrument creation from APIs and AWS Lambda capabilities, clever instrument 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 companies. 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 instrument integration for AI brokers. At its core, Gateway presents highly effective and safe API integration performance that transforms current 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 supplies built-in assist for Lambda capabilities so builders can join their serverless computing sources as instruments with outlined schemas. Gateway supplies the next key capabilities:

• Safety Guard – Manages OAuth authorization so solely legitimate customers and brokers can entry instruments and sources. We’ll 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 just wish to expose as instruments to AI brokers. Targets could 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 supplies complete infrastructure with built-in safety features and strong 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 instrument discovery represents one other core functionality of Gateway. As organizations scale to lots of or hundreds of instruments, discovering the proper instrument turns into more and more difficult for AI brokers. Furthermore, when brokers are offered with too many instruments concurrently, they’ll expertise one thing referred to as “instrument overload,” resulting in hallucinations, incorrect instrument picks, or inefficient execution paths that considerably impression efficiency. Gateway addresses these challenges by offering a particular built-in instrument 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 companies.

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

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

For AWS Lambda and Smithy mannequin targets, AgentCore Gateway makes use of AWS Identification and Entry Administration (IAM) primarily based authorization. The gateway assumes an IAM position you configure, which might have exactly scoped permissions for every goal service. This integrates easily with current 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 sort, enabling safe machine-to-machine communications with out person interplay

Credentials are securely managed by means of AgentCore Identification’s useful resource credentials supplier. Every goal is related to precisely one authentication configuration, facilitating clear safety boundaries and audit trails. AgentCore Identification handles the complicated 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 (by means of AgentCore Identification), and safe communication from there.

Get began with Amazon Bedrock AgentCore Gateway

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

The next sensible examples and code snippets display the method of organising 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": '<cognito_client_id>‘, # Shopper MUST match with the ClientId configured in Cognito.
        "discoveryUrl": '<cognito_oauth_discovery_url>'
    }
}
create_response = gateway_client.create_gateway(identify="DemoGateway",
    roleArn = '<IAM Position>' # The IAM Position will need to have permissions to create/record/get/delete Gateway 
    protocolType="MCP",
    authorizerType="CUSTOM_JWT",
    authorizerConfiguration=auth_config, 
    description='Demo AgentCore Gateway'
)
# Values with < > must be changed with actual values

Create gateway targets

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

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

responseacpscreate_api_key_credential_provider(
identify"APIKey",
apiKey"<your secret API key"
)

credentialProviderARN  response['credentialProviderArn']

# Specify OpenAPI spec file through S3 or inline
openapi_s3_target_config = {
    "mcp": {
          "openApiSchema": {
              "s3": {
                  "uri": openapi_s3_uri
              }
          }
      }
}

# API Key credentials supplier configuration
api_key_credential_config = [
    {
        "credentialProviderType" : "API_KEY", 
        "credentialProvider": {
            "apiKeyCredentialProvider": {
                    "credentialParameterName": "api_key", # Replace this with the name of the api key name expected by the respective API provider. For passing token in the header, use "Authorization"
                    "providerArn": credentialProviderARN,
                    "credentialLocation":"QUERY_PARAMETER", # Location of api key. Possible values are "HEADER" and "QUERY_PARAMETER".
                    #"credentialPrefix": " " # Prefix for the token. Valid values are "Basic". Applies only for tokens.
            }
        }
    }
  ]

# Add the OpenAPI goal to the gateway
targetname="DemoOpenAPITarget"
response = gateway_client.create_gateway_target(
    gatewayIdentifier=gatewayID,
    identify=targetname,
    description='OpenAPI Goal with S3Uri utilizing SDK',
    targetConfiguration=openapi_s3_target_config,
    credentialProviderConfigurations=api_key_credential_config)

Create a goal for a Lambda operate:

# Outline the lambda goal with instrument schema. Exchange the AWS Lambda operate ARN beneath
lambda_target_config = {
  "mcp": {
    "lambda": {
      "lambdaArn": "<Your AWS Lambda operate ARN>",
      "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 operate, its all the time 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 totally different agent frameworks

Use Gateway with Strands Agents integration:

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 possibly can substitute with any mannequin you want
    # Invoke the agent with the pattern immediate. This can solely invoke  MCP listTools and retrieve the record of instruments the LLM has entry to. The beneath doesn't really name any instrument.
    agent("Hello , are you able to record all instruments obtainable to you")
    # Invoke the agent with pattern immediate, invoke the instrument and show the response
    agent("Examine the order standing for order id 123 and present me the precise response from the instrument")

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 decide in to semantic search when making a gateway. It routinely provisions a strong built-in instrument referred to as x_amz_bedrock_agentcore_search that permits clever instrument discovery by means of pure language queries. Use the output of the search instrument instead of MCP’s record operation for scalable and performant instrument discovery. The next diagram illustrates how you should utilize the MCP search instrument.

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

The observability options embody a number of dimensions of gateway operations by means of detailed metrics: utilization metrics (TargetType, IngressAuthType, EgressAuthType, RequestsPerSession), invocation metrics (Invocations, ConcurrentExecutions, Periods), efficiency metrics (Latency, Period, TargetExecutionTime), and error charges (Throttles, SystemErrors, UserErrors). The efficiency metrics could be analyzed utilizing numerous statistical strategies (Common, Minimal, Most, p50, p90, p99) and are tagged with related dimensions for granular evaluation, together with Operation, Useful resource, and Title . For operational logging, Gateway integrates with CloudTrail to seize each administration and information occasions, offering an entire audit path of API interactions. The metrics are accessible by means of each the Amazon Bedrock AgentCore console and CloudWatch console, the place you possibly can create customized dashboards, arrange automated alerts, and carry out detailed efficiency evaluation.

Finest practices

Gateway presents an enhanced debugging possibility by means of the exceptionLevel property, which could be enabled throughout Gateway creation or up to date as proven within the following code instance:

create_response = gateway_client.create_gateway(identify="DemoGateway",
    roleArn = '<IAM Position>' # The IAM Position will need to have permissions to create/record/get/delete Gateway 
    protocolType="MCP",
    authorizerType="CUSTOM_JWT",
    authorizerConfiguration=auth_config, 
    description='Demo AgentCore Gateway',
    exceptionLevel="DEBUG"   # Debug mode for granular error messages
)

When activated, this characteristic supplies extra granular error messages within the content material textual content block (with isError:true) throughout Gateway testing, facilitating faster troubleshooting and integration. When documenting and extracting Open APIs for Gateway, give attention to clear, pure language descriptions that designate real-world use instances. Embody detailed discipline descriptions, validation guidelines, and examples for complicated information buildings whereas sustaining constant terminology all through. For optimum instrument discovery, incorporate related enterprise area key phrases naturally in descriptions and supply context about when to make use of every API. Lastly, take a look at semantic search effectiveness so instruments are discoverable by means of pure language queries. Common evaluations and updates are important to take care of documentation high quality as APIs evolve.When extracting APIs from bigger specs, establish the core performance wanted for agent duties, keep semantic relationships between elements, and protect safety definitions. Observe a scientific extraction course of: evaluate the complete specification, map agent use instances to particular endpoints, extract related paths and schemas whereas sustaining dependencies, and validate the extracted specification.The next are one of the best practices on grouping your APIs right into a Gateway goal:

• Begin with the use case and group your MCP instruments primarily based on the agentic utility’s enterprise area much like domain-driven design ideas relevant to the microservices paradigm.
• You’ll be able to connect just one useful resource credentials supplier for outbound authorization for the Gateway goal. Group the instruments primarily based on the outbound authorizer.
• Group your APIs primarily based on the kind of the APIs, that’s, OpenAPI, Smithy, or AWS Lambda, serving as a bridge to different enterprise APIs.

When onboarding instruments to Gateway, organizations ought to observe a structured course of that features safety and vulnerability checks. Implement a evaluate pipeline that scans API specs for potential safety dangers, maintains correct authentication mechanisms, and validates information dealing with practices. For runtime instrument discovery, use the semantic search capabilities in Gateway, but in addition take into account design-time agent-tool mapping for important workflows to offer predictable habits.

Enrich instrument metadata with detailed descriptions, utilization examples, and efficiency traits to enhance discoverability and support in acceptable instrument choice by brokers. To keep up consistency throughout your enterprise, combine Gateway with a centralized instrument registry that serves as a single supply of reality. This may be achieved utilizing open supply options such because the MCP Registry Publisher Tool, which publishes MCP server particulars to an MCP registry. Repeatedly synchronize Gateway’s instrument stock with this central registry for up-to-date and constant instrument availability throughout your AI panorama. These practices may help keep a safe, well-organized, and effectively discoverable instrument resolution inside Gateway, facilitating seamless agent-tool interactions whereas can align with enterprise governance requirements.
