Migration Path

​
From Claude Agent SDK to MCP Server with LangGraph

If you need to expand beyond Claude or add enterprise features:
1

Map Tools to Graph Nodes

Convert Claude Agent SDK tools to LangGraph nodes:
# Claude Agent SDK
@Tool
def process_data(input: str) -> str:
    return result

# LangGraph
def process_node(state: AgentState) -> AgentState:
    result = process_data(state["input"])
    return {"result": result}

graph.add_node("process", process_node)
2

Handle Context Management Manually

Replace automatic compaction with manual strategies:
# Implement context windowing
# Use LangSmith for tracking
# Add summarization nodes if needed
3

Add Multi-Provider Support

  • Configure LiteLLM for model switching
  • Add fallback logic
  • Set up provider credentials
4

Implement Enterprise Features

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

​
From MCP Server with LangGraph to Claude Agent SDK

If you want to optimize for Claude and simplify infrastructure:
1

Convert Graph to Tools

Map LangGraph nodes to Claude Agent SDK tools:
# LangGraph
graph.add_node("process", process_func)

# Claude Agent SDK
@Tool
def process(input: str) -> str:
    return process_func(input)
2

Leverage Automatic Context Management

  • Remove manual context tracking
  • Enable automatic compaction
  • Use file system integration for large files
3

Simplify Deployment

  • Remove Kubernetes manifests
  • Deploy as Python application
  • Use Anthropic API directly

​
Honest Recommendation

​
If You’re Building with Claude Only:

  • Consider Claude Agent SDK for native integration and automatic context management
  • Consider MCP Server with LangGraph if enterprise features are critical

​
If You Need Multi-Provider Support:

  • Choose MCP Server with LangGraph - Claude Agent SDK doesn’t support other models

​
If Context Management is Critical:

  • Claude Agent SDK has superior automatic context compaction
  • MCP Server with LangGraph requires manual implementation

​
If You’re Going to Production (Enterprise):

  • Choose MCP Server with LangGraph - enterprise security and observability are built-in

​
If You’re Prototyping Code Agents:

  • Claude Agent SDK is faster to get started with Claude-specific features

​
When NOT to Use MCP Server with LangGraph:

Choose Claude Agent SDK instead if:
  • ❌ Claude models only, forever - Committed exclusively to Anthropic/Claude with no multi-provider needs
  • ❌ Automatic context management critical - Claude SDK’s auto-compaction solves a hard problem elegantly
  • ❌ Code-heavy agent tasks - Building coding assistants, debugging agents, or development automation
  • ❌ Checkpointing/rewind essential - Need built-in time-travel debugging for agent states
  • ❌ Simple deployment sufficient - Don’t need enterprise infrastructure (Kubernetes, multi-cloud, etc.)
MCP Server is overkill if:
  • You’re building Claude-only agents and automatic context management is worth vendor lock-in
  • Your use case is specifically code analysis/generation where Claude SDK excels
  • You prefer Anthropic’s opinionated SDK over building custom context strategies
  • Enterprise security, compliance, and observability features aren’t requirements
