Running

MCP Server (streamable-http)

cd /home/tyrel/projects/audio-sep-mcp
AUDIOSEP_MCP_PORT=8769 python mcp_server.py  # serves on http://localhost:8769/mcp

Note: default port 8765 collides with other local MCP servers — the systemd service below overrides it to 8769.

With Gradio UI

python app.py  # serves on :8767

systemd (user services)

Both services are managed as systemd user units and start automatically (linger enabled):

systemctl --user status audio-sep-mcp.service audio-sep-gradio.service
systemctl --user restart audio-sep-mcp.service audio-sep-gradio.service
journalctl --user -u audio-sep-mcp.service -f

Unit files: ~/.config/systemd/user/audio-sep-mcp.service, ~/.config/systemd/user/audio-sep-gradio.service.
