Something is telling me this _might_ turn out to be a huge deal; I can't quite put a finger on what is that makes me feel that, but opening private data and tools via an open protocol to AI apps just feels like a game changer.

LLMs can potentially query _something_ and receive a concise, high-signal response to facilitate communications with the endpoint, similar to API documentation for us but more programmatic.

This is huge, as long as there's a single standard and other LLM providers don't try to release their own protocol. Which, historically speaking, is definitely going to happen.

This is definitely a huge deal - as long as there's a good developer experience - which IMHO we're not there yet!

Any feedback on developer experience is always welcomed (preferably in github discussion/issue form). It's the first day in the open. We have a long long way to go and much ground to cover.

Yes, very much this; I'm mildly worried because the competition in this space is huge and there is no shortage of money and crazy people who could go against this.

Seems from the demo videos like Claude desktop app will soon support MCP. Can you share any info on when it will be rolled out?

Already available in the latest at https://claude.ai/download !

Will this be partially available from the Claude website for connections to other web services? E.g. could the GitHub server be called from https://claude.ai?

Even if I could make use of it, I wouldn't, because I don't write proprietary code that only works on one AI Service Provider. I use only LangChain so that all of my code can be used with any LLM. My app has a simple drop down box where users can pick whatever LLM they want to to use (OpenAI, Perplexity, Gemini, Anthropic, Grok, etc) However if they've done something worthy of putting into LangChain, then I do hope L…

It's an open protocol; where did you get the idea that it would only work with Claude? You can implement it for whatever you want - I'm sure langchain folks are already working on something to accommodate it

Once fully adopted by at least 3 other companies I'll consider it a standard, and would consider it yes, if it solved a problem I have, which it does not.

Lots of companies open source some of their internal code, then say it's "officially a protocol now" that anyone can use, and then no one else ever uses it.

If they have new "tools" that's great however, but only as long as they can be used in LangChain independent of any "new protocol".

I'm on the latest Claude desktop for mac (0.7.1, pro plan). Can't see the mcp icon neither in the app nor in the web. How to troubleshoot?

At the moment only Claude Desktop supports MCP. Claude.ai itself does not.

They will go against this. I don’t want to be that guy, but this moment in time is literally the opening scene of a movie where everyone agrees to work together in the bandit group.

But, it’s a bandit group.

@jspahrsummers and I have been working on this for the last few months at Anthropic. I am happy to answer any questions people might have.

Looking at https://github.com/modelcontextprotocol/python-sdk?tab=readm... it's clear that there must be a decision connecting, for example, `tools` returned by the MCP server and `call_tool` executed by the host.

In case of Claude Desktop App, I assume the decision which MCP-server's tool to use based on the end-user's query is done by Claude LLM using something like ReAct loop. Are the prompts and LLM-generated tokens involved inside "Protocol Handshake"-phase available for review?
