Feature request

Support for interacting with MCP servers.

The Model Context Protocol is an open standard that enables developers to build secure, two-way connections between their data sources and AI-powered tools. The architecture is straightforward: developers can either expose their data through MCP servers or build AI applications (MCP clients) that connect to these servers.

Motivation

It would be very useful if we could connect our chains to MCP servers. There are already some useful tool implementations available in MCP server format.

Is there someone working on this already? If not, I'd love to contribute. Besides, I work at Memorang and I think we might end up using MCP for some of our LangChain/LangGraph workflows anyway.

There is an implementation in https://github.com/rectalogic/langchain-mcp, however it would make much more sense as a toolkit in langchain.
