**English** | [日本語](README.ja.md) OIDC-authenticated reverse proxy for [AWS MCP Server](https://docs.aws.amazon.com/aws-mcp/latest/userguide/getting-started-aws-mcp-server.html). Combines [idproxy](https://github.com/youyo/idproxy) (OIDC auth + OAuth 2.1 AS) with a SigV4-signed `httputil.ReverseProxy` to expose AWS MCP Server as a protected remote MCP endpoint — no `mcp-go` or message-level parsing required.
