### Description (declared)

# Amazon Bedrock AgentCore MCP Proxy

## Overview

This repository addresses two limitations in Amazon Bedrock AgentCore when running MCP servers:

1. **IAM Authentication**: AgentCore requires OAuth 2.0 or Cognito for authentication through the gateway.[^gateway-inbound][^cognito-auth] Developer workstations typically use IAM credentials via Identity Center instead. This repository packages a local stdio proxy that signs requests with SigV4, allowing direct invocation of the AgentCore runtime API[^runtime-how] without configuring OIDC providers or VPC access.

2. **Stateful Bidirectional MCP**: AgentCore's native MCP protocol support is stateless. MCP sampling (server-to-client LLM requests) and elicitation (schema-driven data collection) require persistent sessions. This repository provides an HTTP-to-STDIO bridge that maintains a subprocess across invocations, enabling bidirectional MCP flows within AgentCore's serverless infrastructure.

The local proxy handles IAM authentication and presents a standard MCP stdio interface to clients. Two deployment models are provided for the AgentCore runtime:
- **Stateless**: Direct MCP server for simple request/response tools
- **Stateful**: HTTP bridge maintaining a persistent MCP subprocess for sampling and elicitation workflows
