Hi, I'm Aaron Parecki, Director of Identity Standards at Okta, and co-founder of IndieWebCamp. I maintain oauth.net, write and consult about OAuth, and participate in the OAuth Working Group at the IETF. I also help people learn about video production and livestreaming. (detailed bio)

I've been tracking my location since 2008 and I wrote 100 songs in 100 days. I've spoken at conferences around the world about owning your data, OAuth, quantified self, and explained why R is a vowel. Read more.

You can follow me from Mastodon or any other similar application that uses ActivityPub. Search for my profile (aaronpk@aaronparecki.com) from your instance, or use the use the "Remote Follow" feature below.

    The latest version of the MCP spec is now officially 2025-06-18! Congrats to everyone in the MCP community involved in making this happen!

    Key updates to the authorization section:

    ⚙️ MCP Servers are no longer responsible for issuing access tokens or handling user authentication
    🛡️ A dedicated Authorization Server separate from the MCP Server handles user authentication and issuing access tokens
    🔍 RFC9728 Protected Resource Metadata enables the MCP client to dynamically discover the MCP Server's authorization server
    👉 RFC8707 Resource Indicators are required as a security measure

    Thanks to everyone who contributed to the many discussions to update the authorization part of the spec to be more compatible with existing OAuth systems!

    David Soria Parra, Paul Carleton, Den Delimarsky, Nate Barbettini, William Dawson, Jared Hanson, Karl McGuinness, Darin McAdams, Jean-François LOMBARDO and apologies if I forgot to mention you, those threads were extremely long!

    TIL the point up emoji ☝️ doesn't work as a reaction on iMessage because Apple displays the emoji above the message it's a reaction to 😂

    I’m just gonna say, I feel like a laptop with its lid closed should not take priority over the bluetooth connection to the headphones I just turned on.

    In two weeks I'll be speaking at the MCP Dev Summit in San Francisco! It's going to be a great day packed with back to back sessions.

    In less than a year, the MCP project has quickly reshaped how developers are building AI agents. My talk, "Intro to OAuth for MCP Servers", will cover the basics of the new MCP authorization protocol and set the stage for building secure MCP servers.

How Does This Work?

Would you like to use your own domain to be part of the Fediverse? Rather than finding an existing Mastodon instance to join, you can turn your own website into an ActivityPub profile like this one! Some of these options are more complicated than others, but the links below will get you started in the right direction.

  • Micro.blog is a fully-hosted service you can run on a custom domain or subdomain, and provides ActivityPub integration out of the box.
  • Bridgy Fed converts your existing website to ActivityPub using Webmention, h-entry and Atom.
  • Install a plugin for your WordPress or Drupal website.
  • Nautilus is an open-source proxy server you can run independently from your website.
  • You can self-host a single-user instance of ActivityPub-compatible software like microblog.pub, WriteFreely, or Mastodon.

If you want to go full DIY, you can implement ActivityPub into your own website! I started by following Eugen's guide here.
