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" } }

Debug Mode

Enable debug logging for detailed troubleshooting:

{ "env": { "ZAPMAIL_LOG_LEVEL": "DEBUG" } }

Health Check

Test your MCP connection: In Claude Desktop or Cursor:

"Check the health of my Zapmail connection"

Common MCP Configuration Errors

1. Invalid JSON Syntax

Problem: MCP client fails to load configuration Solution: Validate your JSON configuration using a JSON validator

2. Wrong Command Path

Problem: "Command not found" in MCP client Solution: Use full path or ensure zapmail-mcp is in your PATH

3. Environment Variables Not Loading

Problem: API key not being passed to MCP server Solution: Use the env section in your MCP configuration instead of global environment variables
