I wrote about how DPoP eliminates the "finders keepers" vulnerability of Bearer tokens. The article covers implementation with Keycloak and Quarkus, walks through replay attack and method/URL mismatch scenarios, and includes a ready-to-run repo. https://foojay.io/today/dpop-what-it-is-how-it-works-and-why-bearer-tokens-arent-enough/

I've created a repo that demonstrates how multiple AI agents can communicate and collaborate using Google's open-standard Agent2Agent (A2A) protocol. In the example, a Host Agent classifies user input, makes a routing decision, and forwards the request to the relevant agent via A2A clients using the LLM function call. https://github.com/hakdogan/agent-to-agent-demo
