The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 33 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 2 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Other agent protocols currently lack the adoption required for AAIF inclusion
“At least on the protocol side, like a defector standards. And I don't think any of the other protocols, it feels like they're not just there yet, but of course, if they get there, then we are like super open as long as they're like complementary to what's, wha…”
MCP currently lacks authentication for mutually unknown clients and servers
“But if the client and the server don't know each other, we just don't have a good solution for now.”
Making return streams optional in Streamable HTTP was an MCP design mistake
“We got wrong that. We made a lot of things optional for the clients to do. Like you can, the client can connect and open this return stream from the server, but it doesn't have to. And the reality is, is no client does it because it's optional. And so a lot of…”
Google and Microsoft are already running MCP at millions of requests
“And we know from like some companies like the Googles of the world, the Microsoft of the world, they're doing MCP at a scale that I can't tell you the numbers, but it's like in the million of requests.”
Skills supply vertical domain expertise while MCP provides horizontal system connectivity
“What skills do, they like, they give you the domain knowledge for like a specific Set of tasks, like how you are, how you behave, how should the model behave as a data scientist, or how should the model this behave as an accountant or whatever. But MCP gives y…”
Enterprise MCP adoption is growing much faster internally than publicly visible
“In big enterprises, you see MCP everywhere. And it's actually way growing way faster than you would think because it's mostly internal to companies and without people seeing it.”
MCP strictly handles obtaining context, leaving selection and retention to applications
“And I think MCP I always see is like back to like, it's an application layer protocol. That's just how you obtain the context, how you select the context that the problem for the application. And that's the problem all the agent applications will have at the e…”
Many current community-built MCP servers are mediocre
“I think we see a lot of mediocre MCP services. I mean, some very, very good ones.”
AAIF began when Block asked Anthropic about donating the Goose agent
“We got approached by our friends at block to discuss because they were looking into like donating goose, I think at the time. And so there was a question around doing something together. And then we approached open AI and they were very, very welcoming and lik…”
Altman, Nadella, and Pichai publicly committed to adopting MCP around April
“And then like, you had this like inflection point around April with like Sam Altman and Satya and Sundar and all posting about like MCP and that they're going to adopt MCP at Microsoft, at Google. At OpenAI and that was really like the big inflection point.”
OAuth is fundamentally designed for humans, failing agent-to-agent authentication workflows
“OAuth itself is for the most part, a very human centric protocol. It's just, it just tells you how you obtain a token. If you don't have a token, once you have a token, actually it doesn't matter.”
MCP must enable inherently stateful agents with long-term client-server communication
“MCP should also enable agents, and agents are inherently somewhat stateful, and there's some form of, like, long-term communication going between, like, the client and the server, and so we always looked for something like that.”
MCP is governed by a core maintainer group of eight people
“And so that's why we run MCP as like a really traditional open source project with like a core maintainer group of like eight people that basically decide everything. And then like input from everybody else. Like we get input and people can make suggestions an…”
Underlying LLMs are technically completely uninvolved in the Model Context Protocol
“MCP is a protocol between the AI application and like servers, right? So the model is actually technically not involved in MCP.”
Most AI applications will eventually adopt sandboxed execution environments for code
“And I think you will see evolutions as we're getting better of like how we use these models and the infrastructure around it gets a bit more mature. And you suddenly can assume that most model like AI applications will have some form of like Sandboxing for exe…”
Anthropic created MCP so rapidly expanding internal teams could build integrations independently
“MCP before we even open source it was born of the idea of like, I'm in a company that is growing crazy. I'm in the development side of things, development tooling side of things. I will grow slower than the rest. How can I build something that they can all bui…”
Enterprises will adopt private MCP registries similar to npm and PyPI
“They're effectively using private registries already for NPM. They're using for PyPy and they will also do it for MCP servers. In there you have implicit trust and then you can just search.”
SDKs are likely better than MCP sampling for remote server cases
“In remote cases, it's probably always better for you to bring an SDK, because you have full control, you can deploy it, you can deploy an API case, and maybe even charge someone.”
The vast majority of current MCP usage is for context, not actions
“Most people use it for context. I think that's the vast majority of usage.”
Passing raw OpenAPI specifications directly to LLMs bloats context and causes confusion
“If you put that into a model, like you will have a lot of bloat there too, right? Actually way worse. And funny enough, when people try to like map one to one things, often the model gets slightly confused because You have like search by name, search by ID, se…”
Anthropic and OpenAI are collaborating to build a unified AI UI standard
“And now one thing we just announced three weeks ago on the MCP blog is that we're actually working with all, all two of them together to build like a common standard.”
Regulated MCP clients may require formal certification and signatures within a year
“You might end up in a world really a year from now. There might be clients that have like certifications that they are in Amplik and get like a signature that they are like financial services, MCP clients, and they can prove it for the server. And only then th…”
Anthropic remains fully committed to MCP following its foundation donation
“Like the commitment of Anthropic is the same, right? I'm still, We still have the same people I'm helping with the SDKs. We're still super committed in our products to MCP. I'm still the lead core maintainer. Nothing has actually changed.”
Block's Goose was the first open-source agent to integrate MCP
“Goose was the first open source agent interface or agent that reached out to us and worked with us to integrate MCP. And I think Rad is actually like technically the first non-anthropic contributor to MCP ever on like day two or something like that, like very,…”
Google, Microsoft, Amazon, OpenAI, and Anthropic joined AAIF as platinum members
“You have Google, Microsoft, Amazon Block, Bloomberg, Cloudflare, OpenAI, Anthropic. Just a platinum member, create a foundation.”
Anthropic added long-running tasks to MCP for deep research and communication
“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, y…”
Agentic AI Foundation is the first open-source foundation founded by Anthropic
“Like for us, it's the first time we at Anthropic have an open source foundation.”
MCP decoupled authentication from resource servers to support enterprise identity providers
“In the first iteration of our authentication respect, we combined them together into the MCP server... And if you combine these into the same server, you just can't do this anymore. And so all we needed to do is like, okay, we are a resource server. The MCP se…”
Bloomberg is heading a financial services interest group for MCP standardization
“And so now that's when we, like, started, like, creating this financial services interest group that Bloomberg is heading up to, like, figure out, like, what are some of the things that you, like, a client must do if it wants to speak to our financial services…”
Next MCP update will replace polling with server event callbacks and webhooks
“And then you can make an optimization, which we're going to do in the next round, which we didn't get around is like, okay, instead of having to pull every minute or hour or whatever you interval you choose, the server can call us events. Call you like, feel l…”
Anthropic always planned to put MCP into a neutral open-source foundation
“The first one is that on the MCP side, we always knew that we wanted to find a neutral home for MCP to make sure that the that the industry understands that this is stays open, that this is something safe to adopt.”
