Config last verified Jun 1, 2026

The exact config to run AWS (AWS Labs) in Claude Code — paste it in, restart, and the tools load.

Prerequisites

Claude Code installed.

Setup

1. Open `~/.claude.json`

2. Add this configuration

Add to ~/.claude.json

~/.claude.json

json

{
  "mcpServers": {
    "aws": {
      "command": "uvx",
      "args": [
        "awslabs.aws-api-mcp-server@latest"
      ],
      "env": {
        "AWS_REGION": "<AWS_REGION>",
        "AWS_API_MCP_PROFILE_NAME": "<AWS_API_MCP_PROFILE_NAME>",
        "READ_OPERATIONS_ONLY": "<READ_OPERATIONS_ONLY>"
      }
    }
  }
}

Or via CLI

bash

claude mcp add aws -- uvx awslabs.aws-api-mcp-server@latest

3. Restart Claude Code and confirm the AWS (AWS Labs) tools load.

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
