  2. Verify Actor Critic Thinking is available in the tools list
  3. Test basic Actor Critic Thinking functionality

Troubleshooting

Common Issues

Invalid Total Thoughts Parameter

Symptoms: Parameter validation errors, Odd number requirement failures

Cause: totalThoughts parameter must be odd number ≥3

Solution:

  • Ensure totalThoughts is an odd number (3, 5, 7, etc.)
  • Use minimum value of 3 for basic analysis
  • Verify parameter is numeric, not string
  • Check parameter validation in client configuration

Role Parameter Not Recognized

Symptoms: Invalid role errors, Perspective switching failures

Cause: Role parameter must be exactly "actor" or "critic"

Solution:

  • Use exact values: "actor" or "critic"
  • Check for typos or case sensitivity issues
  • Ensure role alternates between rounds
  • Verify role matches current thought number

Evaluation Sequence Broken

Symptoms: Out of sequence errors, Round tracking failures

Cause: thoughtNumber not matching expected sequence or round progression

Solution:

  • Start thoughtNumber at 1 for first round
  • Increment thoughtNumber for each subsequent round
  • Ensure thoughtNumber ≤ totalThoughts
  • Reset sequence for new evaluation sessions

TypeScript Compilation Errors

Symptoms: Build failures, Type definition errors

Cause: Missing TypeScript dependencies or configuration issues

Solution:

  • Install TypeScript: npm install -g typescript
  • Verify tsconfig.json configuration
  • Install type definitions: npm install @types/node
  • Clear build cache: npm run clean && npm run build

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

Actor Critic Thinking not appearing in MCPHub (mcp.nvim)

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

  • Verify configuration syntax
  • Check Actor Critic Thinking installation
  • Restart MCPHub (mcp.nvim)
  • Check logs for error messages
