​
Migration Path

​
From CrewAI to MCP Server with LangGraph

If you’ve prototyped with CrewAI and need to move to production:
1

Map Roles to Graph Nodes

Convert CrewAI agent roles to LangGraph nodes:
# CrewAI
researcher = Agent(role="Researcher", ...)

# LangGraph
graph.add_node("researcher", research_function)
2

Convert Tasks to State Transitions

Map CrewAI tasks to LangGraph state transitions:
# CrewAI
task = Task(description="Research topic")

# LangGraph
class AgentState(TypedDict):
    topic: str
    research_results: str
3

Add Production Features

  • Implement JWT authentication
  • Configure OpenFGA authorization
  • Set up LangSmith tracing
  • Deploy with Kubernetes/Helm
4

Test & Deploy

  • Run 437 included tests
  • Deploy to staging (GKE staging)
  • Monitor with Grafana dashboards
  • Deploy to production
Migration Effort: Typical 5-agent CrewAI system migrates in 2-5 days. Most time spent on adding production features (auth, observability) rather than code conversion.

​
Honest Recommendation

​
If You’re Just Starting:

  • Start with CrewAI if you’re learning or validating an idea quickly
  • Start with MCP Server with LangGraph if you know you’ll need production features

​
If You’re Going to Production:

  • Choose MCP Server with LangGraph - the production features (security, observability, multi-cloud) are difficult to add later

​
If Budget is Tight:

  • Prototype with CrewAI (free, fast)
  • Migrate to MCP Server with LangGraph when securing funding or launching

​
If You’re Enterprise:

  • Choose MCP Server with LangGraph - CrewAI lacks enterprise security and compliance features

​
When NOT to Use MCP Server with LangGraph:

Choose CrewAI instead if:
  • ❌ Learning AI agents for the first time - CrewAI’s role-based model is more intuitive
  • ❌ Need agent running in under 5 minutes - CrewAI’s crewai create is faster than MCP Server setup
  • ❌ Hackathon or 48-hour project - CrewAI’s speed advantage matters for rapid prototyping
  • ❌ No infrastructure team - MCP Server’s Kubernetes deployment requires DevOps knowledge
  • ❌ Prefer sequential task delegation - CrewAI’s built-in sequential/hierarchical processes are simpler than building graphs
MCP Server is overkill if:
  • You’re building a hobby project with under 100 requests/month
  • You don’t need security, observability, or compliance features
  • You prefer the CrewAI community (100K+ developers vs growing LangGraph ecosystem)
