What motivated the creation of the Model Context Protocol (MCP) and its early design?
Hey everyone, welcome to the Laden Space Podcast. This is Halsio, Founder of Kernel Labs, and I'm joined by Swix, editor of Layden Space.
Hey, and here we are joined finally in the studio for the first time. Uh welcome back, David from Anthropic slash M C P Yeah,
hey. Well boy, nice to finally talk to you in burden. Like uh last time, like a year ago it was over VC and this is way fun.
I watched it back, it was eight months. Uh it's uh it's been a crazy eight months and uh I think we just celebrated like the one year anniversary of MCP. Yes, we at least the public announcement. Yeah. Um and also last night or yesterday was the agente KING launch. Uh
yeah, that was nice. It was nice to see the Enthropic Office. Yeah. And I've been like
Yeah. It's very good food. I I would say um in terms of my food bench, uh Anthropic does rank over OpenAI.
Yeah.
At least that that that's what we have going
for us.
Awesome, man. Do you wanna give just a quick overview of what's happening with MCP and how you're donating it to the foundation? And then we'll do kind of like a one year recap of the protocol itself, and then we'll have the rest of the leads from the foundation join us to do more of the high level.
Yeah, that yeah, that sounds good. Um, yeah, I mean the where where we at at the moment, we have done like a year, like a year ago we launched it and then we had this like crazy adoption over the last year now, which it felt like an eternity, honestly. But we have this like crazy um growth and like adoption, um you know, through initially through like Thanksgiving and Christmas very early, with a lot of like builders building. MCP and then you know you had like the first big clients coming in like Cursor and VS Code and then like you had this like inflection point around April with like Sam Altman and uh Satya and um Sunder and all um posting about like MCP and that they're gonna adopt MCP at Microsoft, at Google, um at OpenAI, and that was really like the big inflection point.
So yeah um But in all of that time, you also had to do a lot of work on the protocol itself, right? We like we we moved, we launched originally as like basically local only. Um you could like build local MCP servers for cloud desktop. Um, but then we like in March this year, we moved into like how can you do remote uh MCP servers to connect like really about like to a remote server and introduce like the first uh iteration of authentication and then in June. and we revisited that and like improved it quite a little bit so that it works better for our um you know uh for enterprises in particular and we were very very lucky that in that time from March to like June we were like able to like have absolute industry leading experts that literally work on OAuth itself to help us with some of the the pieces right um and how to get it right and then we focused a lot of on like security
best practices and this type of work. And now we like have I feel we have a really solid foundation and we're doing we just launched like in our end of like November, then the recent iteration of the protocol, finally like the next bigger improvement to the protocol, which is like long running tasks to really allow for like you know deep research type of task and like, you know, maybe even agent to agent communication. And so I think we're just stepping into like this territory now with like, okay, we have really solid foundations. We have like one more big primitive we wanna have. We want to make like A little bit more scalability, things work, and then we're, you know, gonna get into a phase where it probably becomes a bit more stable.
And so yeah, it's been it's been an absolute crazy year, man.
You did say the agent to agent, so there is a A to A protocol. Um, I'm curious when the agentic A Engineering Foundation got formed, or just Agentec A Foundation. Was there any discussion about any of these other protocols being a part of it? Or you know, Sean Wa wrote a post called YMCP one yeah um already. So uh one of my favorite posts of the maybe was already to go with
