Ai Prompt Optimizer
A lightweight prompt optimization service running on Cloudflare Workers that exposes both REST and MCP interfaces. The server takes your raw prompts and restructures them for better LLM results, handling the tedious work of adding context, clarifying instructions, and formatting for optimal token usage. You'd reach for this when you're iterating on prompts and want programmatic refinement instead of manual tweaking, or when building applications that generate prompts dynamically and need them polished before sending to your primary LLM. The dual transport support means you can hit it via standard HTTP or integrate it directly into Claude through the MCP protocol for seamless prompt improvement in your workflow.
