Pros
  • Reliable, debuggable agent graphs
  • Built-in persistence + HITL
  • Production-grade
  • Tight LangSmith integration
  • Vendor-neutral standard backed by Anthropic, OpenAI, Microsoft, and major IDE vendors
  • Huge and growing library of community-built servers for common tools and data sources
  • Official SDKs in TypeScript, Python, Kotlin, Swift, C#, and Rust
  • Works with both local stdio and remote HTTP/SSE transports
  • Decouples tool integration from any specific model or host
Cons
  • Steeper learning curve than CrewAI
  • Verbose to set up
  • It's a protocol, not a product — you still need a client and servers to do anything useful
  • Spec and SDKs still evolve quickly; expect occasional breaking changes
  • Auth, sandboxing, and permissioning are largely left to the implementer
  • Discovery and trust of third-party servers is still an unsolved UX problem
