Hide hooks, tool permission callbacks, and SDK MCP server APIs from
public interface while keeping implementation code intact. These
features are not yet stable and should not be documented or exposed to
users.
Changes:
- Remove hook-related exports (HookCallback, HookContext, HookMatcher)
from __all__
- Remove tool permission exports (CanUseTool, ToolPermissionContext)
from __all__
- Remove SDK MCP exports (tool, create_sdk_mcp_server, SdkMcpTool) from
__all__
- Delete examples using unstable APIs (tool_permission_callback.py,
mcp_calculator.py)
- Remove SDK MCP server documentation from README

## Summary
Adds in-process SDK MCP server support to the Python SDK, building on
the control protocol from #139.
**Note: Targets `dickson/control` branch (PR #139), not `main`.**
## Key Changes
- Added `@tool` decorator and `create_sdk_mcp_server()` API for defining
in-process MCP servers
- SDK MCP servers run directly in the Python process (no subprocess
overhead)
- Moved SDK MCP handling from Transport to Query class for proper
architectural layering
- Added `McpSdkServerConfig` type and integrated with control protocol
## Example
```python
from claude_code_sdk import tool, create_sdk_mcp_server
@tool("greet", "Greet a user", {"name": str})
async def greet_user(args):
return {"content": [{"type": "text", "text": f"Hello, {args['name']}!"}]}
server = create_sdk_mcp_server(name="my-tools", tools=[greet_user])
options = ClaudeCodeOptions(mcp_servers={"tools": server})
```
## Testing
- Added integration tests in `test_sdk_mcp_integration.py`
- Added example calculator server in `examples/mcp_calculator.py`
