LangChain is the most popular framework for building LLM applications with chains, agents, memory, and retrieval. LangSmith adds observability. Controversial for its abstraction complexity.

MCP is an open protocol for connecting AI models to external tools, data sources, and services. Standardizes how AI assistants interact with the world.
Reviewer scorecard
“Over-abstracted and changes too fast. For anything beyond demos, calling APIs directly with a thin wrapper is more maintainable.”
“The USB-C of AI tool integration. One protocol for connecting AI to any data source or tool. Already widely adopted.”
“The framework that made simple API calls into 500-line abstractions. LangGraph is better but the damage is done.”
“Open protocol backed by Anthropic with rapid adoption across AI tools. Standardization reduces integration fragmentation.”
“Despite the criticism, LangChain's ecosystem (LangSmith, LangGraph, templates) is the most complete platform for LLM apps.”
“MCP is becoming the standard for AI-tool integration. The protocol approach scales better than point-to-point integrations.”
