Troubleshooting

MCP Connection Issues

1. MCP Server Not Found

Problem: "zapmail-mcp command not found" or "npx zapmail-mcp not found" Solutions:

For npx usage:

# Test npx directly
npx zapmail-mcp --version

# If npx fails, try with explicit package version
npx zapmail-mcp@latest --version

# Get help information
npx zapmail-mcp --help

For global installation:

# Install the package globally
npm install -g zapmail-mcp

# Verify installation
zapmail-mcp --version

2. MCP Client Not Detecting Server

Problem: Zapmail tools not appearing in Claude Desktop/Cursor Solutions:

• Restart your MCP client (Claude Desktop/Cursor)
• Check your MCP configuration file syntax
• Verify the command path in your config

3. API Key Issues

Problem: "ZAPMAIL_API_KEY not configured" Solutions:

• Set environment variable in your MCP config:

{
  "mcpServers": {
    "zapmail": {
      "command": "npx",
      "args": ["zapmail-mcp"],
      "env": {
        "ZAPMAIL_API_KEY": "your-api-key"
      }
    }
  }
}

• Or set globally:

export ZAPMAIL_API_KEY="your-api-key"

4. Workspace Context Issues

Problem: Getting data from wrong workspace Solution: Set workspace in MCP config:

{
  "env": {
    "ZAPMAIL_WORKSPACE_KEY": "your-workspace-id"
  }
}

Performance Issues

1. Slow Response Times

Problem: MCP operations taking too long Solutions:

• Enable caching: ZAPMAIL_ENABLE_CACHE="true"
• Increase rate limit delay: ZAPMAIL_RATE_LIMIT_DELAY="2000"
• Check your internet connection

2. Rate Limiting

Problem: "Too many requests" errors Solution: Increase rate limit delay in MCP config:

{
  "env": {
    "ZAPMAIL_RATE_LIMIT_DELAY": "2000"
  }
}
