# ScanSing

> ScanSing reads sheet music. Send a PDF or a photo of a printed score and get MusicXML back, then a single part, the score in another key, or a MIDI file. It is an iPhone app for choir singers, a REST API, and an MCP server for Claude, ChatGPT, Cursor and other AI assistants. A new email gets 20 free pages a month, no card.

## Connect an AI assistant

- [ScanSing for Claude and AI assistants](https://scansing.app/mcp/): the MCP server at `https://mcp.scansing.app/mcp` (Streamable HTTP, OAuth or `Authorization: Bearer` key), its tools, limits and troubleshooting.
- Claude Code: `claude mcp add --transport http scansing https://mcp.scansing.app/mcp`, then `/mcp` to sign in.
- claude.ai, ChatGPT, Cursor: add a custom connector with the same address and sign in with an email or a key.
