Writing a Dice Roller MCP Server in Dart

Let's write a MCP server in Dart. I'd like to make a tool that knows how to roll dice. This way, an LLM can get access to a real source of randomnes.

There's no ready-to-use Dart package, but there's a specification that details how to create such a server.

In its easiest form, the server reads JSON RPC requests from stdin and writes responses to stdout. It is allowed to use stderr for logging. All streams are UTF-8 encoded and adhere to the JSONL format, that is, each request must be a single line.

GitHub Search Syntax for Finding API Keys/Secrets/Tokens

As a security professional, it is important to conduct a thorough reconnaissance. With the increasing use of APIs nowadays, it has become paramount to keep access tokens and other API-related secrets secure in order to prevent leaks. However, despite technological advances, human error remains a factor, and many developers still unknowingly hardcode their API secrets into source code and commit them to public repositories. GitHub, being a widely popular platform for public code repositories, may inadvertently host such leaked secrets. To help identify these vulnerabilities, I have created a comprehensive search list using powerful search syntax that enables the search of thousands of leaked keys and secrets in a single search.

Search Syntax:

(path:*.{File_extension1} OR path:*.{File_extension-N}) AND ({Keyname1} OR {Keyname-N}) AND (({Signature/pattern1} OR {Signature/pattern-N}) AND ({PlatformTag1} OR {PlatformTag-N}))

This is a fork of @lizthegrey excellent gist on securing SSH with 2FA but modified to focus on the first steps one can take toward securing ssh access to Github (or other version control systems) with Apple touch ID button. Designed to prevent key theft from the systems we connect to with 2FA, while maintaining ease of use. From the project "If your Mac has a Secure Enclave, it also has support for strong access controls like Touch ID, or authentication with Apple Watch. You can configure your key so that they require Touch ID (or Watch) authentication before they're accessed. If you store your keys in the Secure Enclave, it's impossible to export them, by design."

Mac client setup

Use TouchID to authenticate logins to GitHub! Since sekey is no longer maintained, let's use secretive instead.
