Summary

AWS Labs' core MCP server — the entry point to AWS's official collection of service-specific MCP servers.

Features

Entry point to the AWS Labs MCP server collection
Routes requests to specialised AWS service servers
Covers documentation, CDK, Lambda, and more

Installation

Set up this MCP server in your favorite AI agent — copy a ready-made configuration below.

Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

Open your agent's MCP configuration file.
Merge the snippet below into it.
Restart the agent — the "AWS Labs MCP" tools will be available.

{
  "mcpServers": {
    "aws-labs-core": {
      "command": "uvx",
      "args": [
        "awslabs.core-mcp-server"
      ]
    }
  }
}

Claude Code

Add the server with a single CLI command.

claude mcp add aws-labs-core -- uvx awslabs.core-mcp-server

Claude Desktop

Add the server to claude_desktop_config.json (Settings → Developer → Edit Config).

Description

AWS Labs maintains a large collection of MCP servers covering individual AWS services, and the Core server is the front door: it helps an assistant discover and route to the right one.

The collection

Rather than one enormous server, AWS publishes focused servers for documentation lookup, CDK and CloudFormation authoring, Lambda, DynamoDB, S3, Bedrock knowledge bases, cost analysis, ECS and EKS, Aurora, and many more. Each is installed independently and does one thing well.

What Core adds

It provides guidance on which server handles a given task and how to configure it, which matters because the collection is large enough that finding the right server is itself a question.

Why the AWS documentation server deserves special mention

AWS's API surface is vast and changes constantly, and models reliably generate plausible-but-wrong AWS code. A documentation server that fetches current reference material substantially improves the output — often more than any other single addition.

Installed with uvx awslabs.core-mcp-server@latest, with each specialised server added as needed. Uses your existing AWS credentials.
