JSONlify

Dealing with JSONL fine-tuning datasets across different AI providers means wrestling with each platform's specific format requirements. This server gives you 13 tools to validate and convert between formats for 11 different providers, so you can prep your training data once and push it wherever you need it. Reach for this when you're managing fine-tuning workflows that span multiple AI platforms, or when you need to quickly check if your JSONL is spec-compliant before kicking off an expensive training run. It exposes its functionality through a streamable HTTP transport, making it accessible from Claude Desktop or any MCP-compatible client without local installation.
