Troubleshooting

Having trouble with Pylee? This guide covers the most common issues and their solutions.

Quick Help: Most setup issues can be resolved by restarting your application completely and checking your API key. If problems persist, try the solutions below.

Common Issues and Solutions

Pylee MCP Server Not Appearing

Symptoms: Claude Desktop or other MCP clients don’t show Pylee as available

Solutions:

1. Verify Configuration File Location

   Ensure your config file is in the correct location:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
   • Linux: ~/.config/Claude/claude_desktop_config.json
2. Check JSON Syntax

   Validate your JSON configuration:

   {
     "mcpServers": {
       "pylee": {
         "command": "npx",
         "args": ["-y", "@pyleeai/pylee@latest"]
       }
     }
   }
   

3. Restart Application

   Completely quit and restart Claude Desktop (or your MCP client)

4. Check Node.js Installation

   Verify Node.js is installed:

   node --version
   npm --version
   

Connection Timeout Issues

Symptoms: MCP server starts but times out when trying to connect

Solutions:

1. Check Internet Connection

   Ensure you have a stable internet connection

2. Verify Firewall Settings

   Make sure your firewall isn’t blocking the connection:

   • Allow npx and node through your firewall
   • Check corporate firewall settings if applicable
3. Test Network Access

   # Test connection to Pylee API
   curl -I https://api.pyleeai.com/health
   

4. Try Alternative Configuration

   If using npx fails, try installing globally:

   npm install -g @pyleeai/mcp-server
   

   Then update your config to use:

   {
     "command": "pylee-mcp-server"
   }
   

Permission Denied Errors

Symptoms: Errors about file permissions or access denied

Solutions:

1. Check File Permissions

   Ensure you can read/write the configuration file:

   # macOS/Linux
   ls -la "~/Library/Application Support/Claude/"
   # or
   ls -la ~/.config/Claude/
   

2. Create Directory if Missing

   # macOS
   mkdir -p "~/Library/Application Support/Claude"
   
   # Linux
   mkdir -p ~/.config/Claude
   

3. Fix Ownership (macOS/Linux)

   # macOS
   sudo chown -R $(whoami) "~/Library/Application Support/Claude"
   
   # Linux  
   sudo chown -R $(whoami) ~/.config/Claude
   

4. Run as Administrator (Windows)

   Try running your text editor as Administrator when editing the config file

Node.js or NPM Issues

Symptoms: Commands not found or version conflicts

Solutions:

macOS

# Install Node.js via Homebrew
brew install node

# Or use Node Version Manager
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
nvm install node
nvm use node

Registry Not Loading

Symptoms: Pylee connects but no registry servers are available

Solutions:

1. Check Registry Status

   1. Log into Pylee Dashboard
   2. Go to “Active Registries”
   3. Verify your registries are activated
2. Refresh Registry

   In your dashboard, click “Refresh” on your active registries

3. Check Permissions

   Ensure you have access to the registries you’re trying to use

4. Test with Different Registry

   Try activating a different registry to isolate the issue

Platform-Specific Issues

macOS

Common macOS Issues

Gatekeeper blocking execution:

# Allow npx to run
sudo spctl --master-disable
# Run your MCP client, then re-enable:
sudo spctl --master-enable

SIP (System Integrity Protection) issues:

• Use Homebrew to install Node.js instead of the system installer
• Avoid modifying system directories

Permission issues with Application Support:

# Fix permissions
sudo chown -R $(whoami) "~/Library/Application Support"
