Expected Result: Multiple audio tracks created with appropriate input routing and naming

Configure Voice Track Routing

Set input routing for vocal tracks

Ask MCPHub (mcp.nvim): "Set the input routing channel of all tracks that have "voice" in their name to Ext. In 2"

Expected Result: All vocal tracks configured to receive input from external input 2

Live Performance Setup

Configure session view for live performance

Ask MCPHub (mcp.nvim): "Set up a live performance session with 8 tracks and 16 scenes for electronic music"

Expected Result: Session view configured with tracks and scenes ready for live triggering

Transport Control

Control playback and recording

Ask MCPHub (mcp.nvim): "Start recording on track 3 and set tempo to 120 BPM"

Expected Result: Recording initiated on specified track with tempo adjusted

Testing Your Setup

1. Launch MCPHub (mcp.nvim)
2. Verify Ableton Live is available in the tools list
3. Test basic Ableton Live functionality

Troubleshooting

Common Issues

Ableton Live Not Responding

Symptoms: OSC messages not received, No communication with Live

Cause: OSC control surface not enabled or incorrect port configuration

Solution:

• Enable AbletonOSC control surface in Live preferences
• Verify OSC ports match configuration (11000/11001)
• Restart Ableton Live after configuration changes
• Check firewall settings allow OSC communication

Port Already in Use

Symptoms: Socket binding errors, Port conflict messages

Cause: Another application using configured ports

Solution:

• Check which process is using the port: netstat -tulpn | grep :65432
• Kill conflicting process or change port in osc_daemon.py
• Use alternative ports (e.g., 65433, 11002, 11003)
• Restart both server and Ableton Live

Python Dependencies Missing

Symptoms: Import errors, Module not found errors

Cause: Required packages not installed properly

Solution:

• Run uv sync to install all dependencies
• Verify Python 3.8+ is installed: python --version
• Check virtual environment is activated
• Install missing packages manually: pip install python-osc fastmcp

OSC Messages Not Routing

Symptoms: Commands not affecting Live, No response from controls

Cause: Incorrect OSC routing or message format

Solution:

• Verify OSC address patterns match Live expectations
• Check OSC message format and data types
• Test basic OSC connectivity with simple messages
• Review osc_daemon.py configuration for routing rules

Plugin Not Loading or Command Not Found

Symptoms: :MCPHub command not recognized, Plugin not appearing in :PlugStatus, No errors but plugin inactive

Cause: Plugin not properly installed or configuration error

Solution:

• Verify plugin is added to plugin manager configuration
• Run plugin manager install command (:PackerInstall, :PlugInstall, or Lazy auto-install)
• Check for errors in :messages after sourcing config
• Ensure dependencies (plenary.nvim, nui.nvim) are installed
• Restart Neovim completely

MCP Server Won't Start

Symptoms: Server status shows "Error", Red indicator on server, Server immediately stops after starting

Cause: Invalid server configuration or missing dependencies

Solution:

• Verify npx is installed and in PATH: npx --version
• Check MCP server package exists: npx -y @modelcontextprotocol/server-filesystem --help
• Review server configuration in setup() - verify command and args
• Check server logs in MCPHub interface for detailed error messages
• Ensure required environment variables are set (e.g., GITHUB_TOKEN)
• Test server manually in terminal: npx -y @modelcontextprotocol/server-filesystem /path

UI Not Displaying Correctly

Symptoms: Blank window, Garbled text, Layout issues, Missing borders

Cause: Terminal or Neovim rendering issues

Solution:

• Verify Neovim version is 0.9 or higher: nvim --version
• Try different border style in ui.border config ("single", "double", "rounded")
• Check terminal supports Unicode and 256 colors
• Update nui.nvim dependency to latest version
• Test with different colorscheme to rule out theme conflicts

Integration with Avante/CodeCompanion Not Working

Symptoms: AI assistant not seeing MCP tools, Tool calls failing, Integration not recognized

Cause: Integration not enabled or incompatible versions

Solution:

• Verify integration is enabled in config: integrations.avante = true
• Ensure Avante.nvim/CodeCompanion.nvim is installed and loaded
• Check versions are compatible - update both plugins to latest
• Restart Neovim after enabling integration
• Check :checkhealth for integration-specific warnings

Marketplace Not Loading

Symptoms: :MCPHubMarketplace shows empty list, Network error in marketplace, Timeout loading servers

Cause: Network connectivity issues or marketplace service unavailable

Solution:

• Verify internet connectivity
• Check firewall allows HTTPS connections
• Try again later if marketplace service is temporarily down
• Review proxy settings if behind corporate firewall
• Check :messages for detailed network error messages

Project-Local Config Not Loading

Symptoms: .mcphub.json ignored, Project servers not appearing, Only global config loaded

Cause: Config file location or format issues

Solution:

• Verify .mcphub.json is in project root (same directory as .git)
• Check JSON syntax is valid using jsonlint or similar tool
• Ensure file name is exactly .mcphub.json (case-sensitive)
• Restart Neovim after creating/modifying project config
• Check file permissions are readable

Ableton Live not appearing in MCPHub (mcp.nvim)

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check Ableton Live installation
• Restart MCPHub (mcp.nvim)
• Check logs for error messages
