💀 Toolbox

🕵️ Turn your AI agent into a network detective! No more Postman, no more browser dev tools — just ask your agent what APIs are being called.

Basic Network Monitoring

Dynamic Network Hook System

🎯 AI writes custom Python functions to intercept and modify requests/responses in real-time!

AI Hook Learning System

💡 Example: "Create a hook that blocks social media trackers, redirects API endpoints, and adds auth headers"

Quickstart (60 seconds)

✅ Recommended Setup (Tested Method)

# 1. Clone the repository
git clone https://github.com/DoomsdayxProductions/Reaper-MCP.git

🎛️ Customize Your Installation

Reaper MCP supports modular tool loading! Disable sections you don't need:

# Minimal installation (only core browser + element interaction)
python src/server.py --minimal

# Custom installation - disable specific sections
python src/server.py --disable-cdp-functions --disable-dynamic-hooks

# List all 11 available tool sections
python src/server.py --list-sections

Available sections:

• browser-management (11 tools) - Core browser operations

• element-interaction (11 tools) - Page interaction and manipulation

• element-extraction (9 tools) - Element cloning and extraction

• file-extraction (9 tools) - File-based extraction tools

• network-debugging (5 tools) - Network monitoring and interception

• cdp-functions (13 tools) - Chrome DevTools Protocol execution

• progressive-cloning (10 tools) - Advanced element cloning

• cookies-storage (3 tools) - Cookie and storage management

• tabs (5 tools) - Tab management

• debugging (6 tools) - Debug and system tools (includes environment validator)

• dynamic-hooks (10 tools) - AI-powered network hooks

💡 Pro Tip: Use --minimal for lightweight deployments or --disable-* flags to exclude functionality you don't need!

Quick Test

Restart your MCP client and ask your agent:

"Use Reaper MCP to navigate to https://example.com and extract the pricing table."

🎯 Advanced Text Input

Revolutionary text input capabilities that solve common automation challenges:

⚡ Instant Text Pasting

# paste_text() - Lightning-fast text input via CDP
await mcp_Reaper_MCP_paste_text(instance_id, "textarea", large_markdown_content, clear_first=True)

• 10x faster than character-by-character typing

• Uses Chrome DevTools Protocol insert_text for maximum compatibility

• Perfect for large content (README files, code blocks, forms)

📝 Smart Newline Handling

# type_text() with newline parsing
await mcp_Reaper_MCP_type_text(instance_id, "textarea", "Line 1\nLine 2\nLine 3", parse_newlines=True, delay_ms=10)

• parse_newlines=True: Converts \n to actual Enter key presses

• Essential for multi-line forms, chat apps, and text editors

• Maintains human-like typing with customizable speed

🔧 Why This Matters

• Form Automation: Handle complex multi-line inputs correctly

• Content Management: Paste large documents instantly without timeouts

• Chat Applications: Send multi-line messages with proper line breaks

• Code Input: Paste code snippets with preserved formatting

• Markdown Editors: Handle content with proper line separations

Real-world impact: What used to take 30+ seconds of character-by-character typing now happens instantly, with proper newline handling for complex forms.

🛡️ Cross-Platform Compatibility & Root Support

Automatic platform detection and privilege handling that eliminates common browser spawning issues:

⚙️ Smart Environment Detection

# Automatic privilege detection and sandbox handling
mcp_Reaper_MCP_validate_browser_environment_tool()  # Diagnose your environment

• Root/Administrator Detection: Auto-adds --no-sandbox when running as root

• Container Detection: Detects Docker/Kubernetes and adds container-specific args

• Platform-Aware: Handles Windows, Linux, macOS differences automatically

• Chrome Discovery: Automatically finds Chrome/Chromium installation

🔧 Flexible Args Handling

// All these formats now work:
{"args": ["--disable-web-security"]}                    // JSON array
{"args": "[\"--disable-web-security\"]"}              // JSON string  
{"args": "--disable-web-security"}                     // Single string

• Multiple Format Support: Accepts JSON arrays, JSON strings, or single strings

• Smart Parsing: Tries JSON first, falls back gracefully

• Backward Compatible: Existing configurations continue to work

📊 Built-in Diagnostics

# Environment validation tool
mcp_Reaper_MCP_validate_browser_environment_tool()
# Returns: platform info, Chrome path, issues, warnings, recommendations

• Pre-flight Checks: Validates environment before browser launch

• Issue Detection: Identifies common problems and provides solutions

• Platform Insights: Detailed system information for debugging

🎯 Why This Matters

• Root User Support: No more "Failed to connect to browser" on Linux servers

• Container Compatibility: Works in Docker, Kubernetes, and serverless environments

• Windows Administrator: Handles UAC and privilege escalation scenarios

• Error Prevention: Catches issues before they cause failures

• Better Debugging: Clear diagnostics for troubleshooting

Real-world impact: Browser spawning now works reliably across all environments - from local development to production containers to CI/CD pipelines.
