Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@apono-io/mcp-aws-managed

Apono MCP server for AWS. Assumes the granted role via STS, then proxies stdio MCP traffic to the managed AWS MCP Server, signing every request with SigV4.

Unlike @apono-io/mcp-aws it spawns no vendor process, so uvx, uv and Python are not required on the host.

Usage

Launched by the Apono CLI via npx. Environment variables:

| Variable | Description | |---|---| | AWS_ACCESS_KEY_ID | Brokered IAM credentials — access key | | AWS_SECRET_ACCESS_KEY | Brokered IAM credentials — secret key | | AWS_SESSION_TOKEN | Brokered IAM credentials — session token | | AWS_ROLE_ARN | ARN of the role to assume via STS | | AWS_REGION | Region for the STS call (default us-east-1) | | AWS_MCP_ENDPOINT | Override the endpoint (default https://aws-mcp.us-east-1.api.aws/mcp; https://aws-mcp.eu-central-1.api.aws/mcp also exists) |

The SigV4 signing service and region are derived from the endpoint hostname, so overriding AWS_MCP_ENDPOINT is enough to switch region.

Limitations

The role is assumed once at startup, as in @apono-io/mcp-aws. Sessions outliving the assumed credentials will see ExpiredToken surface as tool errors rather than as a startup failure.
