LambdaTargetConfiguration

class aws_cdk.aws_bedrock_agentcore_alpha.LambdaTargetConfiguration(lambda_function, tool_schema)

Bases: McpTargetConfiguration

(experimental) Configuration for Lambda-based MCP targets.

This configuration wraps a Lambda function as MCP tools, allowing the gateway to invoke the function to provide tool capabilities.

Stability:

experimental

ExampleMetadata:

infused

Example:

gateway = agentcore.Gateway(self, "MyGateway",
    gateway_name="my-gateway"
)

my_lambda_function = lambda_.Function(self, "MyFunction",
    runtime=lambda_.Runtime.NODEJS_22_X,
    handler="index.handler",
    code=lambda_.Code.from_inline("""
            exports.handler = async (event) => ({ statusCode: 200 });
          """)
)

my_tool_schema = agentcore.ToolSchema.from_inline([
    name="my_tool",
    description="My custom tool",
    input_schema=agentcore.SchemaDefinition(
        type=agentcore.SchemaDefinitionType.OBJECT,
        properties={}
    )
])

# Create a custom Lambda configuration
custom_config = agentcore.LambdaTargetConfiguration.create(my_lambda_function, my_tool_schema)

# Use the GatewayTarget constructor directly
target = agentcore.GatewayTarget(self, "AdvancedTarget",
    gateway=gateway,
    gateway_target_name="advanced-target",
    target_configuration=custom_config,  # Manually created configuration
    credential_provider_configurations=[
        agentcore.GatewayCredentialProvider.from_iam_role()
    ]
)
