I am planning on making these five improvements soon:

GitHub Issues

Phase 1: Quick Wins (High Impact, Low Effort)

1. Issue #22: Add Automatic Parameter Serialization for JSON Objects

• Difficulty: Easy-Medium (4-8 hours)

• Branch: feature/auto-parameter-serialization

• Impact: Eliminates JSON.stringify() boilerplate

1. Issue #23: Implement JSON Auto-Normalization for User-Friendly Input

• Difficulty: Medium (1-2 days)

• Branch: feature/json-auto-normalization

• Impact: Fixes common JSON formatting issues automatically

1. Issue #24: Enhance JSON Error Messages with Fix Suggestions

• Difficulty: Easy (2-4 hours)

• Branch: feature/enhanced-json-errors

• Impact: Better debugging experience with actionable suggestions

Phase 2: Major Features (High Impact, Higher Effort)

1. Issue #25: Create JSON-Specific Query Helper Tools

• Difficulty: Medium-Hard (3-5 days)

• Branch: feature/json-query-helpers

• Impact: Transforms API from SQL-centric to JSON-centric

1. Issue #26: Add Pre-Execution JSON Validation Layer

• Difficulty: Medium-Hard (2-3 days)

• Branch: feature/pre-execution-validation

• Impact: Fail-fast validation with rich error context

I added comprehensive testing for sql injection since the original branch of this server had a vulnerability as reported in the news, just to show it is fixed. I also made another security improvement:

Anthropic won't fix a bug in its SQLite MCP server
