Troubleshooting

Authentication Errors

• Verify your API key is correct and not expired
• Check that you have the correct permissions in your MCP360 account
• Ensure the API key hasn't been revoked

No Servers Available

• Verify you have marketplace MCPs enabled in your account
• Check if you have any custom MCPs created
• Ensure your API key has access to the project with MCPs

Tool Execution Errors

• Verify you've selected a valid MCP server and tool
• Check that all required parameters are provided (marked as "required" in dropdown)
• Verify parameter values match expected types (shown in parameter description)
• For complex types (arrays, objects), use JSON format in parameter value
• Review error messages for specific parameter issues

Connection Issues

• Check your internet connection
• Verify MCP360 services are accessible
• Check if there's a firewall blocking outbound connections
• Ensure your n8n instance can reach https://api.mcp360.ai and https://connect.mcp360.ai
