+MCP Nexus is a platform that provides structured access to Windows debugging tools through the Model Context Protocol. It makes crash dump analysis more accessible by providing standardized tools and real-time progress tracking.
+
+### The Problem We Solve
+
+**Traditional Crash Analysis Challenges:**
+- 🔍 **Complexity**: Requires deep knowledge of Windows internals and debugging tools
+- ⏱️ **Time-consuming**: Manual analysis can take hours or days
+- 🧠 **Expertise Required**: Need specialized debugging skills and experience
+- 📊 **Inconsistent Results**: Different analysts may reach different conclusions
+- 🔧 **Tool Complexity**: WinDBG/CDB have steep learning curves
+
+**MCP Nexus Solution:**
+- 🔧 **Structured Access**: Provides standardized tools for debugging operations
+- ⚡ **Real-time Updates**: Live progress tracking and notifications
+- 📚 **Consistent Results**: Provides structured output formats

-## 📊 Performance Optimization
-
-### Memory Management
-
-**Session Management**:
-- Implement session pooling
-- Use weak references for large objects
-- Implement automatic cleanup
-- Monitor memory usage
-
-**Command Execution**:
-- Use async/await patterns
-- Implement command queuing
-- Use cancellation tokens
-- Cache frequently used results
-
-### Analysis Optimization
-
-**Parallel Processing**:
-- Execute independent commands in parallel
-- Use Task.Run for CPU-intensive operations
-- Implement work stealing for load balancing
-- Use concurrent collections
-
-**Caching Strategy**:
-- Cache symbol information
-- Cache analysis results
-- Implement LRU cache eviction
-- Use memory-mapped files for large data
-
-## 🔒 Security Considerations
-
-### File Access Security
-
-**Dump File Access**:
-- Validate file paths
-- Check file permissions
-- Sanitize user input
-- Implement access controls
-
-**Symbol Server Security**:
-- Use HTTPS for symbol downloads
-- Validate symbol signatures
-- Implement rate limiting
-- Cache symbols securely
-
-### Process Security
-
-**Debugging Process Security**:
-- Run with minimal privileges
-- Isolate debugging processes
-- Implement process sandboxing
-- Monitor resource usage
-
-**Network Security**:
-- Use secure connections
-- Implement authentication
-- Validate all inputs
-- Log security events
+## 📊 Performance Features
+
+### Caching System
+
+**IntelligentCacheService**:
+- **Memory-based caching** - 100MB default limit with configurable size
+- **TTL support** - 30-minute default time-to-live for cache entries
+- **Automatic cleanup** - Expired entries cleaned every 5 minutes
+- **Memory monitoring** - Tracks cache memory usage and triggers eviction
+- **Generic implementation** - Supports any key/value type
+
+### Metrics Collection
+
+**AdvancedMetricsService**:
+- **Performance counters** - Tracks command executions, session operations
+- **Success/failure tracking** - Monitors operation success rates
+- **Histogram support** - Tracks operation timing and distributions
+- **Automatic collection** - Metrics gathered every 30 seconds
+- **Resource monitoring** - Memory and performance statistics
+
+### Symbol Caching
+
+**Symbol Server Configuration**:
+- **Local symbol cache** - Cached symbols for faster loading
+- **Multiple symbol servers** - Microsoft, NuGet, Avast symbol sources
+- **Hot/Cold cache strategy** - Fast local access with server fallback
+- **Configurable timeouts** - 5-minute command, 5-minute symbol server timeouts
+
+## 🔒 Security Features
+
+### Command Validation
+
+**Implemented Security**:
+- **Dangerous command blocking** - Commands like `format`, `del`, `shutdown` are blocked
+- **Path traversal protection** - Prevents `../` directory traversal attacks
+- **SQL injection protection** - Basic SQL injection pattern detection
+- **Input validation** - Empty and whitespace-only commands are rejected
+- **Command length limits** - Commands limited to 1000 characters maximum
+
+**Security Service**:
+- `AdvancedSecurityService.ValidateCommand()` method
+- `SecurityValidationResult` class for validation results
+- Regex patterns for path traversal and SQL injection detection
