I don’t really understand agents. I just don’t get why we need to pretend we have multiple personalities, especially when they’re all using the same model. Can anyone please give me a usecase, that couldn’t be solved with a single API call to a modern LLM (capable of multi-step planning/reasoning) and a proper prompt? Or is this really just about building the prompt, and giving the LLM closer guidance by splitting in…

I don't get it either. Watching implementations on YouTube etc it primarily it feels like a load of verbiage trying to carve out a sub-industry, but the meat on the bone just seems to be defining discreet units of AI actions that can be chained into workflows that interact with non-ai services.

You got. But that is the interesting part! To make AI useful, beyond basic content generation in a chat context you need interaction with the outside world. And you may need iterative workflows that can spawn more work based on the output of those interactions. The focus on Agents as personas is a tangent to the core use case. We could just call this stuff "AI Workflow Orchestration" or something ... and it would remain pretty useful!

"You may not provide the software to third parties as a hosted or managed service" - The Elastic v2 license isn't actually open source like your title mentions: "Open-source JS agent framework" https://github.com/mastra-ai/mastra/blob/main/LICENSE

I mentioned that in the comment. We’re using Elastic v2 for now because we want users to be able to do anything with us, but protect from eg AWS

So it‘s a lie.

Why is it on top of Vercel’s platform?

It looks like theyre using the vercel ai sdk, which really isnt the vercel platform, doesnt have anything to do with any of the rest of vercel. Its actually quite nice and full featured.

By the developers of Gatsby is a minus, not a plus makes me think this is going to be the next abandonware.

Surprised this is comment is not higher. Gatsby was one of the worst technologies I have worked with in my long career of working with various JS libraries and frameworks. Im sure the team is smart and capable, but I would not be advertising their work with Gatsby.

Earlier quoted context omitted.

Oh nice, did you write your own proxy or are you using something like https://www.npmjs.com/package/mcp-proxy ?

I have used `mcp-proxy` but (afaik) you can only use it 1-to-1 and I wanted an N-to-1 proxy so that instead of configuring all my MCP servers in the multiple clients I've tested out I could just add 1 server and pull in everything. I found `mcp-proxy-server` [0] which seemed like it would do what I want but I ran into multiple problems. I added some minor debug logging to it and the ball sort of rolled downhill from…

Thanks for sharing! It's so helpful to hear real world experiences like this. Would you be interested in meeting up on a call sometime? I'd love to chat about how you're using MCP to help inform how we can make all of this easier for folks. We're actively thinking about our APIs for tool use and MCP right now.

This looks really great! How do you make money? Do you charge for deploying these to your platform? I couldnt find anything on pricing

If you watch the demo video you will see the cloud platform we are building at the end. Right now it’s in beta.
