use_aws_mcp is a standalone MCP server that provides AWS CLI functionality through a standardized interface. It replicates the functionality of the use_aws tool from amazon-q-cli, exposing a single MCP tool named use_aws. The server accepts service_name, operation_name, parameters, region, profile_name, and label, and executes AWS CLI commands with proper parameter handling. It includes safety features that detect read-only vs. write operations and truncates large outputs to a maximum of 100KB. It manages the AWS CLI user agent for tracking and automatically formats parameters to kebab-case for CLI compatibility. The server communicates via stdin/stdout using JSON-RPC, enabling integration with MCP clients such as Avante, MCPHub in Neovim, and Cursor. It is fully MCP protocol compliant and provides human-readable command descriptions. Prerequisites include Rust 1.70+, Cargo, AWS CLI installed and configured, and AWS credentials. Build with cargo build --release and run with ./target/release/use_aws_mcp. The README references a description_demo example to illustrate command descriptions.
