Big question in my mind was if OpenAI was going to formally endorse this (since it was created by Anthropic) but we have our answer. MCP is now the industry standard for connecting LLMs to external tools.

so we no longer need langchain and stuff like that, that's a win. But MCP also feels a bit overrated:https://www.lycee.ai/blog/why-mcp-is-mostly-bullshit

I assume they're (for now at least) targeting the old HTTP+SSE version of MCP, and not the new Streaming HTTP version? https://github.com/modelcontextprotocol/specification/pull/2...

There's some other goodies too. OAuth 2.1 support, JSON-RPC Batching... https://github.com/modelcontextprotocol/specification/blob/m...

I hoped OpenAI would support OpenAPI for connecting to tools. Having created a couple of MCP servers, it feels like a less flexible and worse documented API to me. I can’t really see anything that is made better by MCP over OpenAPI. It’s a little bit less code for a lot less options. Give it some time and it will also get Swagger built in. It’s solving a problem that was already robustly solved. So get we go with ano…

Well it’s transport agnostic, for one.

I think a big part of it is defining a stateful connection and codifying the concepts of prompts and tools.

Another issue with OpenAPI / swagger is that you still need to create a client per API, but with MCP it’s all uniform.

I could not find the actual criticism in that article. What's the problem with MCP again? It's the first standard for agents.

That article seems to miss the point by being incurious about _why_ there is hype around MCP instead of LangChain, LangGrah, SmolAgents, LlamaIndex, etc.

We've had tool call frameworks before, but we haven't had a way of making tools that our clients actually talked to. There was no way to build tools that other people could download and run locally without getting them to switch to a client that baked those tools in. It's like the difference between static linking and dynamic linking, but for tool calls.

I feel like that article doesn't really live up to its title. At the end, its basic point is that MCP isn't a magic bullet (I don't think anyone claimed it was?) and that it has a lot of hype. It also makes it clear why MCP is good (ie don't need to rely on LangChain). Feels like its title should be "Why MCP is a Good Step but Doesn't Solve Agents" or something. But then, it wouldn't enable the millenial urge to use "shit".

the problem of agents is not the lack of standards, but reliability (reliability of tool use and reliability of outcomes). MCP does not solve any of that.

That is not mentioned in the article. I am just becoming familiar with MCP myself so I suggest raising the issue: https://github.com/orgs/modelcontextprotocol/discussions
