Hi, I'm Aaron Parecki, Sr 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.

    If you've been using my https://webmention.io service, you'll notice a few changes today.

    Everything should be transparent from a user and API perspective, all your webmention endpoints and API queries should still be working. Please let me know if you run in to any problems!

    I replaced the aging Ruby codebase so that I can more easily fix bugs and make it more secure going forward. Stay tuned for some much-needed UX improvements in the near future as well.

    I'm heading home from 10 days in Vienna/London tomorrow and my stomach still hasn't actually caught up from the jet lag

    Today is the day, MCP is launching the next version of the spec! The 2026-07-28 version brings a bunch of exciting changes like statelessness, but I'm focused on the boring auth side of things that nobody wants to deal with!

    • Issuer validation (RFC 9207)
    • Refresh token and offline_access recommendations
    • Scope clarifications
    • Syncing with RFC 8414 .well-known URI

    In the mean time, there's been a ton of excitement around MCP's Enterprise-Managed Auth extension, with a beta program running in Claude and Okta and new MCP servers shipping support by the day!

    Join me at the MCP spec release party in London tonight to learn about what's new in enterprise MCP security!

    Figuring out how AI agents get access to enterprise apps gets messy fast.

    Static API keys and repeated OAuth flows look fine in a demo, but they completely break down at scale.

    Lately, much of my work in the IETF OAuth Working Group has focused on solving this exact bottleneck.

    By leveraging the Cross-App Access pattern, built on the Identity Assertion JWT Authorization Grant, we can fundamentally change how agents interact with your stack:

    • No more manual OAuth dance: Agents get seamless, scoped access to connected apps entirely behind the scenes.
    • Centralized IT control: Enterprise admins get the clear visibility, security boundaries, and policy control they actually need.

    I’m joining Jiquan Ngiam, CEO of MintMCP, to discuss how this plays out in practice. JQ runs over 20 agents on MintMCP's platform, so we’ll explore what MCP Enterprise-Managed Authorization looks like when deployed across tools like Salesforce, GitHub, and Confluence.

    If you work in identity, security, or are currently figuring out how to safely deploy AI agents in your enterprise, come join the conversation.

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.
