Show HN: Custom guitar tab sheets with Cursor (github.com)

A new open-source tool (Show HN: Custom guitar tab sheets with Cursor) lets you generate and maintain custom guitar tab sheets for any song by chaining a Cursor agent loop with web-scraping and a small local server. The repo (github.com/adiasg/guitar-tabs) requires Cursor, a ScrapingBee API key, and an MCP server running in a virtual environment; you stash your ScrapingBee key in .env, start the MCP server (make venv), open Cursor’s chat and run the single command /make-tab <SONG> by <ARTIST> to create a tab sheet. For the AI/ML community this is notable as a compact, practical demonstration of agent-driven tooling: a conversational agent orchestrates web scraping, parsing and tab generation in a reusable loop. It shows how LLM agents can be integrated with external APIs and local services to automate domain-specific content creation (music notation/transcription), and serves as a neat example for prompt engineering, tool-use patterns and rapid prototyping. Technical caveats include dependence on ScrapingBee for web content retrieval, unresolved model choices for transcription/arrangement (not detailed), and potential copyright/scraping considerations—yet it’s a useful starting point for researchers and builders interested in automating creative, structured outputs with agent architectures.
