Melogen / MCP
Connect Melogen with OAuth, attach a score in ChatGPT or a compatible MCP host, and ask your AI to return MIDI or MXL.
View MCP connection guideFor MCP hosts that support OAuth and file attachments.
The MCP connection is useful when the score is already part of an AI conversation. You describe the files you need; a compatible host passes the attachment to Melogen and retrieves the task result. If you simply want to upload a file and convert it, the browser tool is the more direct route.
Use the connection when you want to keep the attachment, output request and task updates together. You will need a host that can call the conversion tools, complete OAuth authorization and pass file attachments.
Use the online converter when you want to upload the score yourself and work with the website interface. You do not need to configure an MCP host for this route.
Check these three things before sending your first score. A chat interface alone does not mean it can run this workflow.
ChatGPT connection options depend on your account, workspace settings and available app capabilities. Other MCP hosts also need remote MCP support, OAuth and file attachments. Check your host’s connection options before proceeding.
Follow the connection guide and authorize your account through OAuth. Conversion uses your Melogen account and available credits; connecting from a chat does not bypass the service’s account requirements.
Attach a PDF, PNG or JPG containing the score. Keep pages legible and upright, with the staff and page edges intact. These are practical preparation steps, not a guarantee that every note will be recognized.
Attach the file in the host instead of pasting a public URL or a YouTube link. If attachments are unavailable, use the browser converter.
Connect once, then use the conversation to submit your score and retrieve the result.
Follow the MCP connection guide and authorize your Melogen account with OAuth in a compatible host.
Attach a PDF, PNG, or JPG score. Ask for MIDI or MXL; your AI calls start_sheet_music_conversion with the host-provided file descriptor.
Your AI uses get_sheet_music_conversion to check the task. When it succeeds, use the returned links to download the output files.
You do not need to write a tool call. Attach the score, explain the kind of file you need and let your compatible host handle the request. These examples describe requests you can make; they are not recorded conversion results.
Convert this attached score to MIDI. I want to listen to it and work on the notes in my music software. Give me the download link when it is ready.
Choose MIDI when your next step is playback, note editing or arrangement.
Convert the attached score to MXL so I can open it in notation software. Check the task status and send me the file when it is ready.
Choose MXL when your next step is working with the score’s notation.
Please convert this score to both MIDI and MXL. Check the existing task and return the download links after it succeeds.
Ask for both formats when you need a sequence for your DAW and an interchange file for notation editing.
The host supplies the file descriptor. Start the task once, keep its task identifier, and query that task for its status and artifacts. The following is an illustrative request and response, not a live job.
MCP: start_sheet_music_conversion + get_sheet_music_conversion
Your MCP host passes the attached score as a file descriptor. start_sheet_music_conversion submits the task; get_sheet_music_conversion retrieves its status and output files.

}Both outputs describe music, but they serve different downstream workflows. You can request either format or both through this connection.
MIDI stores musical performance information, such as note events. Import it into compatible music software to choose an instrument sound, listen to the sequence or edit notes and timing. It is not an audio recording and does not preserve the visual layout of the printed page.
MXL is compressed MusicXML, a format for exchanging digital sheet music. Open it in compatible notation software to continue editing the score. Import results and layout can vary between applications, so check the file after opening it.
Compare the converted music with the original score. Check notes, rhythm, voices and measures before arranging, rehearsing or distributing it. Keep the original attachment as your reference; a completed task means files were produced, not that every musical detail has been verified.
Start with the stage that failed. A missing connection, an unreadable attachment and a task still processing need different next steps.
Check that your host and account allow the required MCP capabilities, then follow the Melogen connection guide. In a managed workspace, connection access may depend on administrator settings.
Check that you attached a PDF, PNG or JPG rather than just pasting a link. Try attaching the original file again in a compatible host. If the host cannot pass file attachments, use the online converter.
Ask your host to check the existing task rather than start another conversion. Keep the task identifier when reporting a problem. If the task fails, follow the returned message and check your account status before submitting again.
Download the result while its link is valid. If the link has expired or access is denied, check the task’s response and contact support if needed. Avoid starting a new conversion just to troubleshoot a download link.
Authorization, attachments and results in your AI host.
Use a host with MCP connections, OAuth sign-in and file attachments. Follow the Melogen MCP connection guide to authorize your account; available connection options depend on your host and account.
No. Attach a PDF, PNG, or JPG score in a compatible host. The host supplies the file descriptor to the tool; you do not need to create a public file URL yourself.
start_sheet_music_conversion returns a task identifier. The host uses get_sheet_music_conversion to check its status and retrieve the output links after success. Review the downloaded score before using it.
Yes. Use the online sheet music to MIDI converter to upload and convert directly on the website. This MCP page covers the separate connection workflow for ChatGPT and compatible hosts.
No. The MCP connection uses your Melogen account and its available credits. Follow the account and task information shown by the service; this page does not promise a free allowance or a fixed cost for every score.
Check the existing task first. Your host should use the returned task identifier with get_sheet_music_conversion. A second start request can create a separate conversion; keep the original task information when checking progress or asking for support.
