What is the Aws MCP server?

Connect Aws to Claude, Cursor or any other MCP client and it stops being a tab you switch to. This library enables you to utilize AWS Lambda and Amazon API Gateway to respond to web and API requests using your existing Node.js application framework. The aws mcp server is what makes that connection.

What the server does

Starting a new software project? Check out Code Genie - a Full Stack App Generator that delivers a complete AWS Serverless project with source code, based on your data model. Including:

  • Only pay for what you use
  • No infrastructure to manage
  • Auto-scaling with zero configuration
  • Authorization
  • SDK Generation
  • API Monitoring

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • binarySettings — Determine if the response should be base64 encoded before being returned to the event source, for example, when returning images or compressed files
  • eventSource — serverless-express natively supports API Gateway, ALB, Lambda@Edge and VPC Lattice (only V2 events - event source AWS_VPC_LATTICE_V2). If you want to
  • eventSourceRoutes — A single function can be configured to handle additional kinds of AWS events: - SNS - DynamoDB Streams - SQS - EventBridge Events (formerlly
  • logSettings — Specify log settings that are passed to the default logger. Currently, you can only set the log level

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Where it fits

Plenty of cloud and infrastructure servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Aws's toolset — binarySettings, eventSource, eventSourceRoutes and 1 more — is a fair guide to whether it matches your workflow. It is maintained by brettstack; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How to install the Aws MCP server

{
  "mcpServers": {
    "aws-serverless": {
      "command": "npx",
      "args": ["-y", "loadtest"]
    }
  }
}

Add to claude_desktop_config.json, then restart Claude Desktop.

Example prompts to try

  • Use Aws to binarySettings.
  • Use Aws to eventSource.
  • Use Aws to eventSourceRoutes.

Frequently asked questions

It connects Aws to MCP-compatible AI assistants such as Claude and Cursor, exposing 4 tools (binarySettings, eventSource, eventSourceRoutes, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Aws directly.
