AWS MCP Server
Give Claude access to all 200+ AWS services through the AWS CLI.
Demo
What It Does
This MCP server lets Claude run AWS CLI commands on your behalf. Instead of wrapping each AWS API individually, it wraps the CLI itself—giving Claude complete AWS access through just two tools:
| Tool | Purpose |
|---|---|
aws_cli_help |
Get documentation for any AWS command |
aws_cli_pipeline |
Execute AWS CLI commands with optional pipes (jq, grep, etc.) |
Claude learns commands on-demand using --help, then executes them. Your IAM policy controls what it can actually do.
