LangChain connection

[lawnlake]

Hello; forgive me if this is an obvious or a silly one, but what exactly is the relationship between LangChain and mcp-use?

I can't find any explanation as to how the two are related, but seemingly all of the examples and code snippets from the docs - and even tutorial videos on YouTube - strongly imply that they go together. There's even a link to the LangChain docs at the bottom of the mcp-use homepage.

Did LangChain create mcp-use? Is it designed to be use with LangChain products explicitly? From what I gather, MCP is supposed to be platform-agnostic, but the language used in the mcp-use docs don't give that impression.

Again, maybe I missed something obvious.

EDIT: This is a good example of what I mean https://github.com/mcp-use/mcp-use-ts

There’s no formal relationship between LangChain and mcp-use.
We’re not affiliated with LangChain, and they didn’t create mcp-use.

mcp-use was created by @pietrozullo and @Pederzh as an open-source SDK and cloud platform for building and managing MCP-enabled agents.

We currently use LangChain in some examples for the agent execution layer because it’s a well-known orchestration library, but we’re actively evaluating alternatives.

Do you have a framework or runtime you think we should look into?

Thank you for the response. Off-hand, I'd say AnythingLLM, OpenWeb UI, and LM Studio would be worth looking into. Perhaps ComfyUI, but I've only just been playing with it so I can't speak to how MCP-friendly it is to begin with.

But really, simply any other platform (ok, maybe not Claude) would be helpful, if for no other purpose than an implicit reminder of platform-agnosticism.

Between asking my original question and now, however, I see that this isn't exclusive to mcp-use by any means. In fact, it seems that most MCP-related projects have similar language patterns in their documentation.

As someone relatively new to the field, it's a bit confusing is all. It reminds me of the AOL-Netscape-Lycos days of walled-gardens in a new frontier, and the difficulties in adapting to one after the fall/decline of another; the pattern language of each provider was not conducive to platform migration, and I think this stunted the growth of many internet users on the heels of web 2.0 .

Anyway, as I get more familiar with each platform and the concept as a whole, I'd be more than happy to contribute examples from other libraries to supplement the existing documentation. Thanks again for the response!
