+# MCP Performance Monitoring & Dynamic Tool Loading
+
+Bu dokumantasyon MCP server'ında performance ve dinamik tool yükleme stratejilerini açıklar.
+
+## Performance Monitoring
+
+### 1. Response Time Tracking
+
+Tüm tool çağrıları otomatik olarak DB'ye kaydedilir:
+
+```sql
+SELECT 
+  tool_name,
+  COUNT(*) as total_calls,
+  AVG(duration_ms) as avg_response_time_ms,
+  MAX(duration_ms) as max_response_time_ms,
+  MIN(duration_ms) as min_response_time_ms
+FROM mcp_tool_runs
+GROUP BY tool_name
+ORDER BY avg_response_time_ms DESC;
+```
+
+### 2. Tool Stats Endpoint
+
+`tool_stats` aracı DB'den istatistikleri çeker:
+
+```bash
+curl -X POST "http://localhost:8080/mcp" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "jsonrpc":"2.0",
+    "id":1,
+    "method":"tools/call",
+    "params":{
+      "name":"tool_stats",
+      "arguments":{"limit":10}
+    }
+  }'
+```
+
+Yanıt örneği:
+```
+MCP tool stats
+Limit: 10
+
+- api_overview: total=45 success=45 error=0 avg_ms=2.3
+- health_check: total=32 success=31 error=1 avg_ms=45.6
+- codebase_map: total=8 success=8 error=0 avg_ms=156.2
+- md_guide_get: total=12 success=11 error=1 avg_ms=5.1
+- tool_stats: total=3 success=3 error=0 avg_ms=8.4
+```
+
+### 3. Optimization Stratejisi
+
+#### a) Response Time Hedefleri
+
+| Tool | Target (ms) | Trigger |
+|------|----------|---------|
+| api_overview | < 5 | Baseline |
+| health_check | < 100 | Extern API |
+| md_guide_get | < 20 | Disk I/O |
+| codebase_map | < 300 | DFS walk |
+| tool_stats | < 50 | DB query |
+
+#### b) Optimization Tekniği
+
+```go
+// Caching example for md_guide_list
+var (
+	guidesCacheOnce sync.Once
+	guidesCache []string
+	guidesCacheTime time.Time
+	guideCacheTTL = 5 * time.Minute
+)
+
+func cachedListMDGuides() ([]string, error) {
+	now := time.Now()
+	if len(guidesCache) > 0 && now.Sub(guidesCacheTime) < guideCacheTTL {
+		return guidesCache, nil
+	}
+	
+	guides, err := listMDGuides()
+	if err == nil {
+		guidesCacheTime = now
+		guidesCache = guides
+	}
+	return guides, err
+}
+```

+
+## Dynamic Tool Loading (MD/JSON)
+
+### 1. Tool Definition Format (YAML/JSON)
+
+`docs/mcp-tools/tools.yaml` veya `docs/mcp-tools/tools.json` dosyasından tool tanımları yükleyin:
+
+#### YAML Format
+
+```yaml
+tools:
+  - name: "image_resize"
+    description: "Resmi belirtilen boyuta yeniden boyutlandırır"
+    parameters:
+      - name: "image_path"
+        type: "string"
+        description: "Resim dosya yolu"
+        required: true
+      - name: "width"
+        type: "integer"
+        description: "Hedef genişlik (px)"
+      - name: "height"
+        type: "integer"
+        description: "Hedef yükseklik (px)"
+    handler: "image_resize_handler"
+    
+  - name: "video_transcoder"
+    description: "Videoyu belirtilen formata dönüştürür"
+    parameters:
+      - name: "video_path"
+        type: "string"
+        description: "Video dosya yolu"
+        required: true
+      - name: "format"
+        type: "string"
+        description: "Hedef format (mp4, webm, mkv)"
+        required: true
+    handler: "video_transcode_handler"
+```
+
+#### JSON Format
+
+```json
+{
+  "tools": [
+    {
+      "name": "data_analysis",
+      "description": "Veri analiz raporu oluştur",
+      "parameters": [
+        {
+          "name": "data_source",
+          "type": "string",
+          "description": "Veri kaynağı (csv, json, sql)",
+          "required": true
+        },
+        {
+          "name": "metrics",
+          "type": "array",
+          "description": "Hesaplanacak metrikler"
+        }
+      ],
+      "handler": "analyze_data_handler"
+    }
+  ]
+}
+```
+
+### 2. Dynamic Tool Registry
+
+`app/mcp/dynamic_tools.go` oluştur:
+
+```go
+package mcp
+
+import (
+	"encoding/json"
+	"fmt"
+	"os"
+	"path/filepath"
+	"sync"
+
+	mcpgo "github.com/mark3labs/mcp-go/mcp"
+	mcpserver "github.com/mark3labs/mcp-go/server"
+)
+
+type ToolDefinition struct {
+	Name        string            `json:"name" yaml:"name"`
+	Description string            `json:"description" yaml:"description"`
+	Parameters  []ParameterDef    `json:"parameters" yaml:"parameters"`
+	Handler     string            `json:"handler" yaml:"handler"`
+}
+
+type ParameterDef struct {
+	Name        string   `json:"name" yaml:"name"`
+	Type        string   `json:"type" yaml:"type"`
+	Description string   `json:"description" yaml:"description"`
+	Required    bool     `json:"required" yaml:"required"`
+	Enum        []string `json:"enum" yaml:"enum"`
+}
+
+type DynamicToolRegistry struct {
+	tools map[string]ToolDefinition
+	mu    sync.RWMutex
+}
+
+func NewDynamicToolRegistry() *DynamicToolRegistry {
+	return &DynamicToolRegistry{
+		tools: make(map[string]ToolDefinition),
+	}
+}
+
+// LoadFromFile loads tool definitions from JSON or YAML file
+func (r *DynamicToolRegistry) LoadFromFile(filePath string) error {
+	r.mu.Lock()
+	defer r.mu.Unlock()
+
+	data, err := os.ReadFile(filePath)
+	if err != nil {
+		return fmt.Errorf("read file: %w", err)
+	}
+
+	var config struct {
+		Tools []ToolDefinition `json:"tools" yaml:"tools"`
+	}
+
+	if err := json.Unmarshal(data, &config); err != nil {
+		return fmt.Errorf("parse tools: %w", err)
+	}
+
+	for _, tool := range config.Tools {
+		r.tools[tool.Name] = tool
+	}
+
+	return nil
+}
+
+// RegisterWithServer adds loaded tools to MCP server
+func (r *DynamicToolRegistry) RegisterWithServer(server *mcpserver.MCPServer) error {
+	r.mu.RLock()
+	defer r.mu.RUnlock()
+
+	for name, toolDef := range r.tools {
+		tool := mcpgo.NewTool(
+			toolDef.Name,
+			mcpgo.WithDescription(toolDef.Description),
+		)
+
+		// Add parameters dynamically
+		for _, param := range toolDef.Parameters {
+			switch param.Type {
+			case "string":
+				opts := []mcpgo.ToolOption{
+					mcpgo.Description(param.Description),
+				}
+				if param.Required {
+					opts = append(opts, mcpgo.Required())
+				}
+				tool = tool.WithString(param.Name, opts...)
+			case "integer":
+				opts := []mcpgo.ToolOption{
+					mcpgo.Description(param.Description),
+				}
+				if param.Required {
+					opts = append(opts, mcpgo.Required())
+				}
+				tool = tool.WithNumber(param.Name, opts...)
+			case "boolean":
+				opts := []mcpgo.ToolOption{
+					mcpgo.Description(param.Description),
+				}
+				if param.Required {
+					opts = append(opts, mcpgo.Required())
+				}
+				tool = tool.WithBool(param.Name, opts...)
+			}
+		}
+
+		// Get handler from registry and add to server
+		handler := r.getHandler(toolDef.Handler)
+		if handler == nil {
+			return fmt.Errorf("handler not found: %s", toolDef.Handler)
+		}
+
+		server.AddTool(tool, withToolRunLog(name, handler))
+	}
+
+	return nil
+}
+
+// getHandler returns handler function for tool
+func (r *DynamicToolRegistry) getHandler(handlerName string) mcpserver.ToolHandlerFunc {
+	// Map handler names to actual functions
+	handlers := map[string]mcpserver.ToolHandlerFunc{
+		"image_resize_handler":      imageResizeHandler,
+		"video_transcode_handler":   videoTranscodeHandler,
+		"analyze_data_handler":      analyzeDataHandler,
+	}
+	return handlers[handlerName]
+}
+
+// Handler implementations
+func imageResizeHandler(ctx context.Context, req mcpgo.CallToolRequest) (*mcpgo.CallToolResult, error) {
+	imagePath, err := req.RequireString("image_path")
+	if err != nil {
+		return mcpgo.NewToolResultError(err.Error()), nil
+	}
+	
+	width := req.GetInt("width", 0)
+	height := req.GetInt("height", 0)
+
+	// TODO: Implement image resizing logic
+	result := fmt.Sprintf("Resized %s to %dx%d", imagePath, width, height)
+	return mcpgo.NewToolResultText(result), nil
+}
+
+func videoTranscodeHandler(ctx context.Context, req mcpgo.CallToolRequest) (*mcpgo.CallToolResult, error) {
+	videoPath, err := req.RequireString("video_path")
+	if err != nil {
+		return mcpgo.NewToolResultError(err.Error()), nil
+	}
+	
+	format, err := req.RequireString("format")
+	if err != nil {
+		return mcpgo.NewToolResultError(err.Error()), nil
+	}
+
+	// TODO: Implement video transcoding logic
+	result := fmt.Sprintf("Transcoding %s to %s", videoPath, format)
+	return mcpgo.NewToolResultText(result), nil
+}
+
+func analyzeDataHandler(ctx context.Context, req mcpgo.CallToolRequest) (*mcpgo.CallToolResult, error) {
+	dataSource, err := req.RequireString("data_source")
+	if err != nil {
+		return mcpgo.NewToolResultError(err.Error()), nil
+	}
+
+	// TODO: Implement data analysis logic
+	result := fmt.Sprintf("Analyzing data from %s", dataSource)
+	return mcpgo.NewToolResultText(result), nil
+}
+```
+
+### 3. Server'a Entegre Et
+
+`server_mcpgo.go` içine ekle:
+
+```go
+func newMCPGoServer() *mcpserver.MCPServer {
+	s := mcpserver.NewMCPServer("ginimage-api-mcp", "0.1.0")
+
+	// ... existing tools ...
+
+	// Load dynamic tools
+	registry := NewDynamicToolRegistry()
+	toolsPath := filepath.Join("docs", "mcp-tools", "tools.json")
+	if err := registry.LoadFromFile(toolsPath); err == nil {
+		_ = registry.RegisterWithServer(s)
+	}
+
+	return s
+}
+```
+
+### 4. Usage Example
+
+**docs/mcp-tools/tools.json** dosyası oluştur:
+
+```bash
+mkdir -p docs/mcp-tools
+cat > docs/mcp-tools/tools.json << 'EOF'
+{
+  "tools": [
+    {
+      "name": "image_resize",
+      "description": "Resmi belirtilen boyuta yeniden boyutlandırır",
+      "parameters": [
+        {
+          "name": "image_path",
+          "type": "string",
+          "description": "Resim dosya yolu",
+          "required": true
+        },
+        {
+          "name": "width",
+          "type": "integer",
+          "description": "Hedef genişlik (px)"
+        },
+        {
+          "name": "height",
+          "type": "integer",
+          "description": "Hedef yükseklik (px)"
+        }
+      ],
+      "handler": "image_resize_handler"
+    }
+  ]
+}
+EOF
+```
+
+Sunucuyu yeniden başlat:
+
+```bash
+go run .
+```
+
+Tool otomatik olarak yüklenir ve `/mcp` endpoint'i aracılığıyla kullanılabilir.

+
+## Sık Kullanılan Optimization Teknikleri
+
+### 1. Caching
+
+```go
+var cache = make(map[string]interface{})
+var cacheMu sync.RWMutex
+
+func getCached(key string) (interface{}, bool) {
+	cacheMu.RLock()
+	defer cacheMu.RUnlock()
+	val, ok := cache[key]
+	return val, ok
+}
+```
+
+### 2. Pooling
+
+```go
+var bufferPool = sync.Pool{
+	New: func() interface{} {
+		return new(bytes.Buffer)
+	},
+}
+```
+
+### 3. Concurrency Control
+
+```go
+var sem = make(chan struct{}, maxConcurrentTools)
+
+func withSemaphore(f func() error) error {
+	sem <- struct{}{}
+	defer func() { <-sem }()
+	return f()
+}
+```
