AWS MCP Servers MCP Server

Install

uvx awslabs.core-mcp-server@latest

Example config (Cursor / Claude Desktop)

{
  "mcpServers": {
    "aws": {
      "command": "uvx",
      "args": [
        "awslabs.core-mcp-server@latest"
      ],
      "env": {
        "AWS_SECRET_ACCESS_KEY": "<your-value>",
        "AWS_SESSION_TOKEN": "<your-value>"
      }
    }
  }
}

VS Code uses "servers" instead of "mcpServers" (why). On Windows, wrap npx with cmd /c (fix).

Common problems

• Too many MCP tools: tool limits in Windsurf, Cursor and VS Code
• Fix "spawn uvx ENOENT" for Python MCP servers
