- Use the String JSON Schema constructor when creating the Tool programaticaly.
- Enhance StdioClientTransport error logging with more context
- Add ToolHelper utility class for:
- Converting Spring AI FunctionCallbacks to MCP tools
- Generating JSON schemas for tool input validation
- Facilitating integration between Spring AI functions and MCP tools

- Move ServerParameters to o.s.ai.mcp.client.transport
- StdioClientTransport.errorHandler changed to private with
setter method Migration: Use setErrorHandler() method
instead of direct field access
API Changes
- Replace static factory methods with builder pattern
- Update ServerCapabilities to use builder pattern
- Make StdioClientTransport.errorHandler private with setter
