From the guys who wrote the MCP authorization spec Anthropic adopted. figuring out how to safely give agents access to production systems is a big problem. glad i invested!

We saw the action and control layer coming. Now we're going to own it.

Everyone focused on the models. We focused on what happens when the agent actually does something.

congrats to arcade for their launch!

they make it super easy to use thousands of tools

if you want to try them out with langchain - easiest way is probably our no-code agent builder: https://docs.langchain.com/langsmith/fleet/arcade

@andykonwinski Completely agree! We had the same observation working on SREGym/Stratus -- if AI for prod is going to be a real thing we need a safe action space for agents to do so.
