 ```go
 type Config struct {
+    service.ServiceConf              // Always embed for services
     Host     string `json:",default=0.0.0.0"`
-    Port     int    `json:",default=8080"`

 ### REST API Development
 
-1. **API Definition**: Use `.api` files to define REST APIs
-2. **Handler pattern**: Separate business logic into logic packages
-3. **Middleware**: Use built-in middlewares (tracing, logging, metrics, recovery)
-4. **Response handling**: Use `httpx.WriteJson` for JSON responses
-5. **Error handling**: Use `httpx.Error` for HTTP error responses
+1. **API Definition**: Use `.api` files to define REST APIs with goctl codegen
+2. **Handler pattern**: Separate business logic into logic packages (handlers call logic layer)
+3. **Middleware chain**: Middlewares wrap via `chain.Chain` interface - use `Append()` or `Prepend()` to control order
+   - Built-in middlewares (all in `rest/handler/`): tracing, logging, metrics, recovery, breaker, shedding, timeout, maxconns, maxbytes, gunzip
+   - Custom middleware: `func(http.Handler) http.Handler` - call `next.ServeHTTP(w, r)` to continue chain
+4. **Response handling**: Use `httpx.WriteJson(w, code, v)` for JSON responses
+5. **Error handling**: Use `httpx.Error(w, err)` or `httpx.ErrorCtx(ctx, w, err)` for HTTP error responses
+6. **Route registration**: Routes defined with `Method`, `Path`, and `Handler` - wildcards use `:param` syntax
 
 ### RPC Development
 
-1. **Protocol Buffers**: Use protobuf for service definitions
-2. **Service discovery**: Integrate with etcd for service registration
-3. **Load balancing**: Use built-in load balancing strategies
-4. **Interceptors**: Implement interceptors for cross-cutting concerns
+1. **Protocol Buffers**: Use protobuf for service definitions, generate code with goctl
+2. **Service discovery**: Use etcd for dynamic service registration/discovery, or direct endpoints for static routing
+3. **Load balancing**: Default is `p2c_ewma` (power of 2 choices with EWMA), configurable via `BalancerName`
+4. **Client configuration**: Support `Etcd`, `Endpoints`, or `Target` - use `BuildTarget()` to construct connection string
+5. **Interceptors**: Implement gRPC interceptors for cross-cutting concerns (auth, logging, metrics)
+6. **Health checks**: gRPC health checks enabled by default (`Health: true`)
 
 ### Database Operations
 
-1. **SQL operations**: Use `sqlx` package for database operations
-2. **Caching**: Implement caching patterns with `cache` package
-3. **Transactions**: Use proper transaction handling
-4. **Connection pooling**: Configure appropriate connection pools
+1. **SQL operations**: Use `sqlx.SqlConn` interface - methods always end with `Ctx` for context support
+2. **Caching pattern**: `stores/sqlc` provides `CachedConn` for automatic cache-aside pattern
+   - `QueryRowCtx`: Query with cache key, auto-populate on cache miss
+   - `ExecCtx`: Execute and delete cache keys
+3. **Transactions**: Use `sqlx.SqlConn.TransactCtx()` to get transaction session
+4. **Connection pooling**: Managed automatically (64 max idle/open, 1min lifetime)
+5. **Test helpers**: Use `redistest.CreateRedis(t)` for Redis, SQL mocks for DB testing

+### Common Issue Patterns and Solutions
+
+#### Configuration Issues
+- Check `service.ServiceConf` embedding and struct tags
+- Verify YAML syntax, defaults, and validation rules
+- Reference: [rest/config.go](rest/config.go), [zrpc/config.go](zrpc/config.go)
+
+#### Code Generation (goctl) Issues
+- Verify `.api` or `.proto` file syntax and goctl version
+- Reference: `tools/goctl/` directory
+
+#### RPC Connection Issues
+- Check etcd configuration, service discovery, and endpoints
+- Verify load balancing settings (p2c_ewma)
+
+#### Database/Cache Issues
+- Verify `sqlx.SqlConn` usage with context
+- Check cache key generation, invalidation, and connection pools
+- Use test helpers (`redistest`, `mongtest`)
+
+#### Performance Issues
+- Check if load shedding is enabled (mode: `pre`/`pro`)
+- Review circuit breaker thresholds, rate limiting, and context timeouts
+
+### Referencing Codebase
+
+When explaining issues, reference specific files and patterns:
+- REST API: `rest/`, `rest/handler/`, `rest/httpx/`
+- RPC: `zrpc/`, `zrpc/internal/`
+- Core utilities: `core/breaker/`, `core/limit/`, `core/load/`, etc.
+- Gateway: `gateway/`
+- MCP: `mcp/`
+- Code generation: `tools/goctl/`
+- Examples: `adhoc/` directory contains various examples
+
+### Encouraging Best Practices
+
+When responding to issues, gently guide users toward:
+- Proper error handling with context
+- Using resilience features (breakers, rate limiters)
+- Following testing patterns with table-driven tests
+- Implementing proper resource cleanup
+- Reading existing documentation in `docs/` and `readme.md`
+

 ### Service Configuration
@@ -189,9 +306,39 @@ Always implement proper resource cleanup using defer and context cancellation.
 ## Build and Test Commands
 
 - Build: `go build ./...`
-- Test: `go test ./...`  
+- Test: `go test ./...`
 - Test with race detection: `go test -race ./...`
 - Format: `gofmt -w .`
-- Generate code: `goctl api go -api *.api -dir .`
+- Code generation:
+  - REST API: `goctl api go -api *.api -dir .`
+  - RPC: `goctl rpc protoc *.proto --go_out=. --go-grpc_out=. --zrpc_out=.`
+  - Model from SQL: `goctl model mysql datasource -url="user:pass@tcp(host:port)/db" -table="*" -dir="./model"`
+
+## Critical Architecture Patterns
+
+### Resilience Design Philosophy
+go-zero implements defense-in-depth with multiple protection layers:
+1. **Circuit Breaker** (`core/breaker`): Google SRE breaker - tracks success/failure, opens on error threshold
+2. **Adaptive Load Shedding** (`core/load`): CPU-based auto-rejection when system overloaded (disabled in dev/test/rt modes)
+3. **Rate Limiting** (`core/limit`): Token bucket (Redis-based) and period limiters
+4. **Timeout Control**: Cascading timeouts via context - set at multiple levels (client, server, handler)
+
+### Middleware Chain Architecture
+`rest/chain` provides middleware composition:
+```go
+// Middleware signature
+type Middleware func(http.Handler) http.Handler
+
+// Chain operations
+chain := chain.New(m1, m2)
+chain.Append(m3)    // Adds to end: m1 -> m2 -> m3
+chain.Prepend(m0)   // Adds to start: m0 -> m1 -> m2 -> m3
+handler := chain.Then(finalHandler)
+```
+
+### Concurrency Patterns
+- **MapReduce** (`core/mr`): Parallel processing with worker pools - use for batch operations
+- **Executors** (`core/executors`): Bulk/period executors for batching operations
+- **SingleFlight** (`core/syncx`): Deduplicates concurrent identical requests
 
 Remember to run tests and ensure all checks pass before submitting changes. The project emphasizes high quality, performance, and reliability, so these should be primary considerations in all development work.

+// can exhaust all available connections, causing other operations to fail or timeout.
+//
+// CreateBlockingNode creates a separate Redis client with a minimal connection pool (size 1) that
+// is dedicated to blocking operations. This ensures blocking commands don't interfere with regular
+// Redis operations.
+//
+// Example usage:
+//
+//	rds := redis.MustNewRedis(redis.RedisConf{
+//	    Host: "localhost:6379",
+//	    Type: redis.NodeType,
+//	})
+//
+//	// Create a dedicated node for blocking operations
+//	node, err := redis.CreateBlockingNode(rds)
+//	if err != nil {
+//	    // handle error
+//	}
+//	defer node.Close() // Important: close the node when done
+//
+//	// Use the node for blocking operations
+//	value, err := rds.Blpop(node, "mylist")
+//	if err != nil {
+//	    // handle error
+//	}
+//
+// The returned ClosableNode must be closed when no longer needed to release resources.

+# Migration to Official MCP SDK
+
+This document describes the migration from the custom MCP implementation to the official [go-sdk](https://github.com/modelcontextprotocol/go-sdk).
+
+## Changes
+
+### Dependencies
+
+Added the official MCP SDK:
+```bash
+go get github.com/modelcontextprotocol/go-sdk@v1.2.0
+```
+
+### Type System
+
+All types are now re-exported from the official SDK:
+- `Tool` → `sdkmcp.Tool`
+- `CallToolRequest` → `sdkmcp.CallToolRequest`
+- `CallToolResult` → `sdkmcp.CallToolResult`
+- Content types (`TextContent`, `ImageContent`, etc.)
+- `Prompt`, `Resource`, `Server`, `ServerSession`
+
+### Server Interface
+
+The `McpServer` interface has been simplified:
+
+```go
+type McpServer interface {
+    Start()
+    Stop()
+    Server() *sdkmcp.Server  // Returns underlying SDK server
+}
+```
+
+**Important**: The `AddTool`, `AddPrompt`, and `AddResource` methods have been removed. Use the SDK directly:
+
+```go
+// Old (no longer supported)
+server.AddTool(tool, handler)
+
+// New (use SDK directly)
+sdkmcp.AddTool(server.Server(), tool, handler)
+```
+
+### Configuration
+
+Updated configuration structure:
+- Removed: `ProtocolVersion`, `BaseUrl` (SDK manages these)
+- Added: `UseStreamable` (choose between SSE and Streamable HTTP transport)
+
+```yaml
+mcp:
+  name: my-server
+  version: 1.0.0
+  useStreamable: false  # false = SSE (2024-11-05), true = Streamable HTTP (2025-03-26)
+  sseEndpoint: /sse
+  messageEndpoint: /message
+  sseTimeout: 24h
+  messageTimeout: 30s
+  cors:
+    - http://localhost:3000
+```
+
+### Tool Registration
+
+The SDK uses Go generics for type-safe tool registration:
+
+```go
+import sdkmcp "github.com/modelcontextprotocol/go-sdk/mcp"
+
+type MyArgs struct {
+    Value string `json:"value" jsonschema:"description=Input value"`
+}
+
+tool := &mcp.Tool{
+    Name:        "my_tool",
+    Description: "Description",
+}
+
+handler := func(ctx context.Context, req *mcp.CallToolRequest, args MyArgs) (*mcp.CallToolResult, any, error) {
+    return &mcp.CallToolResult{
+        Content: []mcp.Content{
+            &mcp.TextContent{Text: "Result"},
+        },
+    }, nil, nil
+}
+
+// Register with explicit type parameters
+sdkmcp.AddTool(server.Server(), tool, handler)
+```
+
+The SDK automatically generates JSON schemas from struct tags.
+
+### Transport Support
+
+Two transports are supported:
+
+1. **SSE (Server-Sent Events)**: 2024-11-05 MCP spec
+   - Default (`UseStreamable: false`)
+   - Endpoint: `/sse` (configurable)
+   - Bidirectional: client sends messages to `/message`
+
+2. **Streamable HTTP**: 2025-03-26 MCP spec
+   - Opt-in (`UseStreamable: true`)
+   - Endpoint: `/sse` (configurable)
+   - Newer protocol with improved streaming
+
+### Example Migration
+
+**Before:**
+```go
+server := mcp.NewMcpServer(c)
+
+tool := &mcp.Tool{Name: "greet", Description: "Greet"}
+handler := func(ctx context.Context, req *mcp.CallToolRequest, args GreetArgs) (*mcp.CallToolResult, any, error) {
+    return &mcp.CallToolResult{
+        Content: []mcp.Content{&mcp.TextContent{Text: "Hello"}},
+    }, nil, nil
+}
+
+if err := server.AddTool(tool, handler); err != nil {
+    log.Fatal(err)
+}
+```
+
+**After:**
+```go
+import sdkmcp "github.com/modelcontextprotocol/go-sdk/mcp"
+
+server := mcp.NewMcpServer(c)
+
+tool := &mcp.Tool{Name: "greet", Description: "Greet"}
+handler := func(ctx context.Context, req *mcp.CallToolRequest, args GreetArgs) (*mcp.CallToolResult, any, error) {
+    return &mcp.CallToolResult{
+        Content: []mcp.Content{&mcp.TextContent{Text: "Hello"}},
+    }, nil, nil
+}
+
+// Use SDK directly - no error return
+sdkmcp.AddTool(server.Server(), tool, handler)
+```
+
+## Benefits
+
+1. **Official SDK**: Uses the official Model Context Protocol SDK
+2. **Type Safety**: Go generics provide compile-time type checking
+3. **Auto Schema**: JSON schemas generated automatically from struct tags
+4. **Dual Transport**: Supports both SSE and Streamable HTTP transports
+5. **Maintained**: SDK is actively maintained by the MCP team
+
+## Breaking Changes
+
+1. `server.AddTool()` removed → use `sdkmcp.AddTool(server.Server(), ...)`
+2. `server.AddPrompt()` removed (SDK v1.2.0 limitation)
+3. `server.AddResource()` removed (SDK v1.2.0 limitation)
+4. Config fields `ProtocolVersion` and `BaseUrl` removed
+5. All types now come from SDK (re-exported for convenience)
+
+## Migration Checklist
+
+- [ ] Update imports: add `sdkmcp "github.com/modelcontextprotocol/go-sdk/mcp"`
+- [ ] Replace `server.AddTool()` with `sdkmcp.AddTool(server.Server(), ...)`
+- [ ] Remove error handling for tool registration (SDK doesn't return errors)
+- [ ] Update config: remove `ProtocolVersion` and `BaseUrl`, add `UseStreamable`
+- [ ] Test with both SSE and Streamable transports
+- [ ] Update documentation/examples

 ## Backgrounds of go-zero
 
-In early 2018, we embarked on a transformative journey to redesign our system, transitioning from a monolithic architecture built with Java and MongoDB to a microservices architecture. After careful research and comparison, we made a deliberate choice to:
+In early 2018, we transitioned from a Java+MongoDB monolithic architecture to microservices, choosing:
 
-* Go Beyond with Golang
-  * Great performance
-  * Simple syntax
-  * Proven engineering efficiency
-  * Extreme deployment experience
-  * Less server resource consumption
-
-* Self-Design Our Microservice Architecture
-  * Microservice architecture facilitates the creation of scalable, flexible, and maintainable software systems with independent, reusable components.
-  * Easy to locate the problems within microservices.
-  * Easy to extend the features by adding or modifying specific microservices without impacting the entire system.
+* **Golang** - High performance, simple syntax, excellent deployment experience, and low resource consumption
+* **Self-designed microservice framework** - Better problem isolation, easier feature extension, and faster issue resolution
 
 ## Design considerations on go-zero
 
-By designing the microservice architecture, we expected to ensure stability, as well as productivity. And from just the beginning, we have the following design principles:
+go-zero follows these core design principles:
 
-* Keep it simple
-* High availability
-* Stable on high concurrency
-* Easy to extend
-* Resilience design, failure-oriented programming
-* Try best to be friendly to the business logic development, encapsulate the complexity
-* One thing, one way
-
-After almost half a year, we finished the transfer from a monolithic system to microservice system and deployed on August 2018. The new system guaranteed business growth and system stability.
+* **Simplicity** - Keep it simple, first principle
+* **High availability** - Stable under high concurrency
+* **Resilience** - Failure-oriented programming with adaptive protection
+* **Developer friendly** - Encapsulate complexity, one way to do one thing
+* **Easy to extend** - Flexible architecture for growth
 
 ## The implementation and features of go-zero
 
-go-zero is a web and rpc framework that integrates lots of engineering practices. The features are mainly listed below:
+go-zero integrates engineering best practices:
 
-* Powerful tool included, less code to write
-* Simple interfaces
-* Fully compatible with net/http
-* Middlewares are supported, easy to extend
-* High performance
-* Failure-oriented programming, resilience design
-* Builtin service discovery, load balancing
-* Builtin concurrency control, adaptive circuit breaker, adaptive load shedding, auto-trigger, auto recover
-* Auto validation of API request parameters
-* Chained timeout control
-* Auto management of data caching
-* Call tracing, metrics, and monitoring
-* High concurrency protected
-
-As below, go-zero protects the system with a couple of layers and mechanisms:
+* **Code generation** - Powerful tools to minimize boilerplate
+* **Simple API** - Clean interfaces, fully compatible with net/http
+* **High performance** - Optimized for speed and efficiency
+* **Resilience** - Built-in circuit breaker, rate limiting, load shedding, timeout control
+* **Service mesh** - Service discovery, load balancing, call tracing
+* **Developer tools** - Auto parameter validation, cache management, metrics and monitoring

-##  Quick Start
+## AI-Native Development
 
-1. Full examples can be checked out from below:
+The go-zero team provides AI tooling for Claude, GitHub Copilot, Cursor to generate framework-compliant code.
+
+### Three Core Projects
+
+**[ai-context](https://github.com/zeromicro/ai-context)** - Workflow guide for AI assistants
+
+**[zero-skills](https://github.com/zeromicro/zero-skills)** - Pattern library with examples
+
+**[mcp-zero](https://github.com/zeromicro/mcp-zero)** - Code generation tools via Model Context Protocol
+
+### Quick Setup
+
+#### GitHub Copilot
+```bash
+git submodule add https://github.com/zeromicro/ai-context.git .github/ai-context
+ln -s ai-context/00-instructions.md .github/copilot-instructions.md  # macOS/Linux
+# Windows: mklink .github\copilot-instructions.md .github\ai-context\00-instructions.md
+git submodule update --remote .github/ai-context  # Update
+```
+
+#### Cursor
+```bash
+git submodule add https://github.com/zeromicro/ai-context.git .cursorrules
+git submodule update --remote .cursorrules  # Update
+```
+
+#### Windsurf
+```bash
+git submodule add https://github.com/zeromicro/ai-context.git .windsurfrules
+git submodule update --remote .windsurfrules  # Update
+```
+
+#### Claude Desktop
+```bash
+git clone https://github.com/zeromicro/mcp-zero.git && cd mcp-zero && go build
+# Configure: ~/Library/Application Support/Claude/claude_desktop_config.json
+# Or: claude mcp add --transport stdio mcp-zero --env GOCTL_PATH=/path/to/goctl -- /path/to/mcp-zero
+```
+
+### How It Works
+
+AI assistants use these tools together:
+1. **ai-context** - workflow guidance
+2. **zero-skills** - implementation patterns
+3. **mcp-zero** - real-time code generation
+
+**Example**: Creating a REST API → AI reads **ai-context** for workflow → calls **mcp-zero** to generate code → references **zero-skills** for patterns → produces production-ready code ✅
