# 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
|
||

// Get handler from registry and add to server

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 {

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
|
||
}
|
||
|

|
||
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()
|
||
}
|
||
```
