This MCP server contains 36 operations which is significantly more than the recommended maximum of tools for most AI clients.

🔍 Recommended Alternative for basic use cases

Seek a simplified MCP server that utilizes the official n8n tool implementation for U.S. EPA Enforcement and Compliance History Online (ECHO) - Clean Water Act (CWA) Rest Services if available, or an MCP server with only common operations as it will be more efficient and easier to manage.

🛠️ Advanced Usage Requirements

BEFORE adding this MCP server to your client:

Disable or delete unused nodes - Review sections and disable/delete those you don't need

AFTER adding the MCP server to your client:
1.Selective tool enabling - Instead of enabling all tools (default), manually select only the specific tools you need for that Workflow's MCP client.
2. Monitor performance - Too many tools can slow down AI responses

💡 Pro Tips

Keep maximum 40 enabled tools - Most AI clients perform better with fewer tools

Group related operations and only enable one group at a time
