Super excited to try out the new agent memory features

#72Happy Mastra user here! Strikes the right balance between letting me build with higher level abstractions but providing lower level controls when needed. I looked at a handful of other frameworks before getting started and the clarity & easy of use of Mastra stood out. Nice work.

#73"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
If the license isn't open source, then the SDK shouldn't be labeled as open source.

#74I basically learned everything about how agents work by using Mastra's framework and going through their documentation. The founders are also super hands-on and love to help!

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.
I appreciate the offer but I think you'll probably find someone better to talk to here in the comments.
MCP is super cool and I've loved playing with it but playing with it is all I'm doing. I'm working on some tools to use in my $dayJob and also just using it as an excuse to learn about LLMs and play with new tech. Most my work is writing tools that connect our to our distributed fleet of servers to collect data, run commands, etc. My goal is to build a SlackOps-type bot that can provide extra context about errors we get in Slack (Pull the latest commits/PRs around that code, link to current deployed version, provide all the logs for the request that threw an error, check system stats, etc). And while I have tools written to do all of that I'm still working on bringing it all together in something more than a bot I can invoke from Slack and make MCP calls.
All that to say, I'm not a professional user of MCP/Mastra and my opinion is probably not one you want shaping your framework.

thank you!

#78I 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…
Without checking out this particular framework, the word is sometimes overloaded with that meaning (LLM personality), but actually in software engineering in general, "agent" generally means something with its own inner loop and branching logic (agent as in autonomy). It's a neccessary abstraction when you compose multiple workflows together under the same LLM interface, things like which flow to run next, and edge case handling for each of them etc.

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.
> 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…
I wont trust an agent with anything by itself at their current state though.
