Work with Quickbase via Model Context Protocol

# Future Improvements

This document captures improvement items for future consideration. These items were extracted from the v2.0.0 release process and can be converted to SDD tickets when prioritized.

## Type Safety

- **Reduce TypeScript `any` types**: 72 ESLint warnings exist for `any` types in API response handling. While not critical for security, improving type definitions would enhance code maintainability and catch potential bugs at compile time.

## Test Coverage

- **Increase overall test coverage to 80%+**: Current coverage is 42.57%. Higher coverage would improve confidence in code changes and reduce regression risk.
- **Improve file operations test coverage**: File operations currently have only 20% coverage. Given the security-critical nature of file handling, these deserve comprehensive tests.
- **Add dedicated test files for tools**: Many tools lack dedicated test files. Each tool should have corresponding unit tests covering success paths, error handling, and edge cases.

## Code Quality

- **Refactor duplicate path validation in file upload tool**: The file upload tool contains duplicate path validation logic that could be refactored to use the centralized file utilities, improving consistency and reducing maintenance burden.

## Features

- **Add webhook support**: Enable real-time notifications from Quickbase events to external systems.
- **Implement streaming for large datasets**: Handle large query results more efficiently without loading everything into memory at once.
- **Support for Quickbase formulas and relationships**: Add tools or capabilities to work with Quickbase formula fields and table relationships.

## Enhancement

- **Add circuit breaker pattern to retry logic**: While exponential backoff exists, adding a circuit breaker pattern would prevent overwhelming failing services and improve system resilience.
- **Secure token storage**: User token is currently stored in the config object. Consider more secure storage mechanisms for sensitive credentials.
- **Add more comprehensive logging options**: Expand logging configuration to support different output formats, log levels per component, and structured logging for production environments.
