+## Release Notes - Version 0.2.0
+
+### New Features
+- **Tool Registration Validation**: Added type assertions and runtime checks to ensure that only valid `Tool` instances are registered.
+- **Enhanced Error Handling**: Improved error messages for better debugging and user experience. "Local MCP servers should not log messages to stdout (standard out), as this will interfere with protocol operation." - https://modelcontextprotocol.io/docs/tools/debugging#server-side-logging
+
+### Improvements
+- **TypeScript Configuration**: Updated `tsconfig.json` to include declaration file generation.
+- **Build Process**: Enhanced build scripts to ensure proper file permissions and output directory structure.
+
+### Bug Fixes
+- **Service Registration**: Fixed issues with tool registration.
+- **File Permissions**: Corrected file permission settings post-build to avoid runtime errors.
+
+### Breaking Changes
+- **Module Exports**: Added [`exports`](https://docs.npmjs.com/cli/v11/configuring-npm/package-json#exports) field to `package.json` to ensure proper module resolution. Fixing: Avoid `ERR_PACKAGE_PATH_NOT_EXPORTED` when importing `MCPServer` in external libraries, i.e.: `mcp-tools`.
+
+### Documentation
+- **README**: Updated with usage instructions, UML diagram, and contribution guidelines.
+
