Cremote MCP Tools - Performance & Best Practices

This document provides performance optimization guidelines and best practices for using the cremote MCP tools effectively in production environments.

🚀 Performance Optimization

1. Batch Operations for Maximum Efficiency

✅ 10x Form Efficiency

Instead of this (10+ API calls):

web_interact_cremotemcp:
  action: "fill"
  selector: "#field1"
  value: "value1"

web_interact_cremotemcp:
  action: "fill"
  selector: "#field2"
  value: "value2"

# ... 8 more individual calls

Use this (1-2 API calls):

web_form_fill_bulk_cremotemcp:
  form_selector: "#form"
  fields:
    field1: "value1"
    field2: "value2"
    field3: "value3"
    # ... all fields in one call

✅ Batch Data Extraction

Instead of this (multiple calls):

web_extract_cremotemcp:
  type: "element"
  selector: "h1"

web_extract_cremotemcp:
  type: "element"
  selector: ".price"

web_extract_cremotemcp:
  type: "element"
  selector: ".description"

Use this (single call):

web_extract_multiple_cremotemcp:
  selectors:
    title: "h1"
    price: ".price"
    description: ".description"

2. Smart Element Checking

✅ Prevent Timing Issues

Always check before acting:

# 1. Check if element exists and is ready
web_element_check_cremotemcp:
  selector: "#submit-button"
  check_type: "all"

# 2. Only proceed if element is ready
web_interact_cremotemcp:
  action: "click"
  selector: "#submit-button"

✅ Form Intelligence

Analyze before filling:

# 1. Understand form structure first
web_form_analyze_cremotemcp:
  selector: "#registration-form"

# 2. Fill based on analysis results
web_form_fill_bulk_cremotemcp:
  form_selector: "#registration-form"
  fields:
    # Fields based on analysis

3. Efficient File Operations

✅ Bulk File Transfers

Instead of individual uploads:

file_operations_bulk_cremotemcp:
  operation: "upload"
  files:
    - local_path: "/file1.pdf"
      container_path: "/tmp/file1.pdf"
    - local_path: "/file2.pdf"
      container_path: "/tmp/file2.pdf"
    # Multiple files in one operation

✅ Automated Cleanup

file_management_cremotemcp:
  operation: "cleanup"
  pattern: "/tmp/cremote-*"
  max_age: "24"  # Clean files older than 24 hours

🎯 Best Practices for LLM Agents

1. Error Prevention Strategies

✅ Always Check Element State

# Check before every interaction
web_element_check_cremotemcp:
  selector: "#target-element"
  check_type: "exists"

# Only proceed if element exists

✅ Verify Page Loading State

# Check if page is fully loaded
web_content_check_cremotemcp:
  type: "scripts"

# Check if images are loaded
web_content_check_cremotemcp:
  type: "images"

✅ Monitor JavaScript Errors

# Check for console errors
console_logs_cremotemcp:
  clear: false

# Look for error patterns in logs

2. Timeout Management

✅ Appropriate Timeout Values

Navigation: 10-15 seconds for complex pages
Element interactions: 5-10 seconds
Form operations: 10-15 seconds for complex forms
File operations: 30-60 seconds for large files

web_navigate_cremotemcp:
  url: "https://complex-app.com"
  timeout: 15  # Longer for complex pages

web_form_fill_bulk_cremotemcp:
  form_selector: "#complex-form"
  fields: {...}
  timeout: 15  # Longer for complex forms

3. Resource Management

✅ Tab Management

# Open new tab for parallel operations
web_manage_tabs_cremotemcp:
  action: "open"

# Close tabs when done
web_manage_tabs_cremotemcp:
  action: "close"
  tab: "tab-id"

✅ Memory Management

# Monitor performance impact
web_performance_metrics_cremotemcp: {}

# Clean up files regularly
file_management_cremotemcp:
  operation: "cleanup"
  pattern: "/tmp/*"
  max_age: "1"

📊 Performance Monitoring

1. Page Performance Tracking

# Get baseline performance
web_performance_metrics_cremotemcp: {}

# Perform operations...

# Check performance impact
web_performance_metrics_cremotemcp: {}

Key Metrics to Monitor:

load_time: Page load duration
dom_content_loaded: DOM ready time
resource_count: Number of resources loaded
js_heap_size_used: Memory usage

2. Viewport Optimization

# Check viewport for responsive testing
web_viewport_info_cremotemcp: {}

# Adjust operations based on viewport size

🛠 Debugging Best Practices

1. Enhanced Screenshots for Debugging

✅ Element-Specific Screenshots

# Screenshot specific problematic elements
web_screenshot_element_cremotemcp:
  selector: "#problematic-element"
  output: "/tmp/debug-element.png"

✅ Enhanced Screenshots with Metadata

# Full context screenshots
web_screenshot_enhanced_cremotemcp:
  output: "/tmp/debug-full-context.png"
  full_page: true

2. Console Debugging

# Check for JavaScript errors
console_logs_cremotemcp:
  clear: false

# Execute debug commands
console_command_cremotemcp:
  command: "console.log(document.readyState)"

3. Page State Analysis

# Get comprehensive page information
web_page_info_cremotemcp: {}

# Check content loading state
web_content_check_cremotemcp:
  type: "scripts"

🎯 Production Deployment Guidelines

1. Environment Configuration

# Optimal environment variables
export CREMOTE_HOST=localhost
export CREMOTE_PORT=8989
export CREMOTE_TIMEOUT=30

2. Resource Limits

Concurrent Operations: Limit to 3-5 parallel browser tabs
File Operations: Monitor disk space for temporary files
Memory Usage: Monitor JavaScript heap size

3. Error Handling Patterns

# Always include error checking
web_element_check_cremotemcp:
  selector: "#target"
  check_type: "exists"

# Implement retry logic for critical operations
# (handled by LLM agent logic)

4. Monitoring and Logging

Monitor web_performance_metrics_cremotemcp results
Track console_logs_cremotemcp for errors
Use enhanced screenshots for debugging
Implement automated cleanup with file_management_cremotemcp

🚀 Advanced Optimization Techniques

1. Parallel Operations

Use multiple tabs for parallel data collection:

# Open multiple tabs for parallel processing
web_manage_tabs_cremotemcp:
  action: "open"

# Process different pages simultaneously

2. Intelligent Caching

Cache form analysis results for similar forms
Reuse element attribute data when possible
Store performance baselines for comparison

3. Conditional Workflows

Use element checking to create smart, adaptive workflows:

# Adapt workflow based on page state
web_element_check_cremotemcp:
  selector: "#login-required"
  check_type: "exists"

# LLM decides next steps based on result
