Bedrock Agentcore Samples Typescript

Amazon Bedrock AgentCore TypeScript Samples

TypeScript samples for building AI agents with Amazon Bedrock AgentCore.

What is Amazon Bedrock AgentCore?

Amazon Bedrock AgentCore is a fully managed service for deploying and running AI agents in production. It provides:

• Runtime — Managed infrastructure for hosting agents and MCP servers
• Identity — Secure credential management for both accessing agents and agents accessing external services
• Memory — Persistent conversation and context storage
• Gateway — Unified MCP layer for agents accessing REST APIs, Lambda functions, and more
• Tools — Built-in Code Interpreter and Browser capabilities

The TypeScript SDK

The `bedrock-agentcore` SDK provides the building blocks for TypeScript agents.

Runtime

`BedrockAgentCoreApp` wraps any agent framework in an HTTP server that follows the AgentCore Runtime protocol—handling request parsing, streaming responses, and session management for seamless deployment:

import { BedrockAgentCoreApp } from 'bedrock-agentcore/runtime'

const app = new BedrockAgentCoreApp({
  invocationHandler: {
    process: async function* (request, context) {
      // Your agent logic here
      yield { event: 'message', data: { text: 'Hello!' } }
    },
  },
})

app.run() // Starts HTTP server on :8080

With a full agent framework:

import { Agent, BedrockModel, tool } from '@strands-agents/sdk'
import { BedrockAgentCoreApp } from 'bedrock-agentcore/runtime'
import { z } from 'zod'

const getWeather = tool({
  name: 'getWeather',
  description: 'Gets weather for a city',
  inputSchema: z.object({ city: z.string() }),
  callback: ({ city }) => `72°F and sunny in ${city}`,
})

const agent = new Agent({
  model: new BedrockModel({ modelId: 'global.amazon.nova-2-lite-v1:0', region: 'us-east-1' }),
  tools: [getWeather],
})

const app = new BedrockAgentCoreApp({
  invocationHandler: {
    requestSchema: z.object({ prompt: z.string() }),
