## Migration Path

### From Claude Agent SDK to MCP Server with LangGraph

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

<Steps>
  <Step title="Map Tools to Graph Nodes">
    Convert Claude Agent SDK tools to LangGraph nodes:

    ```python theme={null}
    # 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)
    ```
  </Step>

  <Step title="Handle Context Management Manually">
    Replace automatic compaction with manual strategies:

    ```python theme={null}
    # Implement context windowing
    # Use LangSmith for tracking
    # Add summarization nodes if needed
    ```
  </Step>

  <Step title="Add Multi-Provider Support">
    * Configure LiteLLM for model switching
    * Add fallback logic
    * Set up provider credentials
  </Step>

  <Step title="Implement Enterprise Features">
    * Add JWT authentication
    * Configure OpenFGA authorization
    * Set up LangSmith tracing
    * Deploy with Kubernetes/Helm
  </Step>
</Steps>

### From MCP Server with LangGraph to Claude Agent SDK

If you want to optimize for Claude and simplify infrastructure:

<Steps>
  <Step title="Convert Graph to Tools">
    Map LangGraph nodes to Claude Agent SDK tools:

    ```python theme={null}
    # LangGraph
    graph.add_node("process", process_func)

    # Claude Agent SDK
    @Tool
    def process(input: str) -> str:
        return process_func(input)
    ```
  </Step>

  <Step title="Leverage Automatic Context Management">
    * Remove manual context tracking
    * Enable automatic compaction
    * Use file system integration for large files
  </Step>

  <Step title="Simplify Deployment">
    * Remove Kubernetes manifests
    * Deploy as Python application
    * Use Anthropic API directly
  </Step>
</Steps>

## 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
