Overview

What is secured-remote-mcp-server-on-aws?

secured-remote-mcp-server-on-aws is a solution that securely publishes an MCP Server using API Gateway (HTTP) with OAuth2 authentication as the entry point, routing through a private Lambda inside a VPC to access S3. It provides a simple example returning S3 file lists but can be extended by implementing different MCP Server logic in Lambda.

How to use secured-remote-mcp-server-on-aws?

Clone the repository, set up the devcontainer environment, configure .env and .auto.tfvars, bootstrap HCP Terraform with terraform init/plan/apply, then obtain an OAuth access token using the just get-token command. Finally, configure an MCP Client (e.g., VSCode's mcp.json) with the API Gateway endpoint URL and Bearer token.

Key features of secured-remote-mcp-server-on-aws

  • OAuth2 authentication via API Gateway and Cognito
  • Private Lambda execution inside a VPC
  • S3 access through VPC endpoints
  • Terraform-based infrastructure as code
  • Devcontainer for reproducible development environment
  • HCP Terraform for deployment management
  • Supports both local and remote MCP clients

Use cases of secured-remote-mcp-server-on-aws

  • Securely exposing an MCP Server to external clients with authentication
  • Accessing private S3 buckets through a Lambda-based MCP endpoint
  • Portfolio demonstration of production-grade AWS infrastructure deployment
  • Extending the Lambda to access various other AWS resources via MCP

Frequently asked questions

1

What authentication mechanism does it use?

OAuth2. The API Gateway entry point requires a Bearer token issued by AWS Cognito. Obtain the token via the provided `just get-token` command.

2

What are the prerequisites?

A devcontainer runtime environment, a GitHub-linked HCP Terraform account, and an AWS account with an IAM Identity Center user.

3

Where is the MCP Server code located?

In the `/src` directory, implemented with FastMCP in Python (`main.py`), with dependencies managed via uv and packaged as a Lambda Layer in `/src/deps`.

4

Does the server run inside a VPC?

Yes. The Lambda function is placed inside a VPC with private subnets. VPC endpoints for Lambda and S3 are used to avoid internet exposure.

5

What transport does the MCP server use?

HTTP. The server is exposed via API Gateway (HTTP type) and clients connect using the HTTP transport with a Bearer token in the Authorization header.
