Agent is a thin wrapper over LangChain AgentExecutor, not production-ready
From 2 comments

Structured error handling so LLMs can decide to retry
From 1 comment
The prod-readiness concerns are fair, but mcp-use fills a real gap in the MCP stack: orchestration across many servers with far less boilerplate than the official SDK. Even if…

Better client documentation with examples of using the client without the agent
From 1 comment
I'm confused -- I didn't see a single example in you readme or docs that uses the client WITHOUT your agent. Trying to understand if this is an alternative to FastMCP. I don't…

Hey, this is really cool. But why should I use this and not the official SDK?
alepeak on HNGreat idea! Definitely going to use it. What are some good reasons to prefer this over fastmcp clients? https://gofastmcp.com/clients/client
