+```
+
+#### Usage Examples
+
+**Basic Usage:**
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent
+from langchain_openai import ChatOpenAI
+
+# Connect to MCP gateway
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Get tools
+tools = toolkit.get_tools()
+
+# Create agent
+llm = ChatOpenAI(model="gpt-4")
+agent = initialize_agent(tools, llm, verbose=True)
+
+# Use agent!
+result = agent.run("Create a user named Alice")
+```
+
+**Advanced Features:**
+```python
+# With authentication
+toolkit = GoMicroToolkit.from_gateway(
+    "http://localhost:3000",
+    auth_token="your-bearer-token"
+)
+
+# Filter by service
+user_tools = toolkit.get_tools(service_filter="users")
+
+# Select specific tools
+tools = toolkit.get_tools(include=["users.Users.Get", "users.Users.Create"])
+
+# Exclude tools
+tools = toolkit.get_tools(exclude=["users.Users.Delete"])
+
+# Call tools directly
+result = toolkit.call_tool("users.Users.Get", '{"id": "user-123"}')
+```
+
+**Multi-Agent Workflows:**
+```python
+# Specialized agents for different services
+user_agent = initialize_agent(
+    toolkit.get_tools(service_filter="users"),
+    ChatOpenAI(model="gpt-4")
+)
+
+order_agent = initialize_agent(
+    toolkit.get_tools(service_filter="orders"),
+    ChatOpenAI(model="gpt-4")
+)
+
+# Coordinate between agents
+user = user_agent.run("Create user Alice")
+order = order_agent.run(f"Create order for {user}")
+```

+
+## Prerequisites
+
+You need at least one microservice running with the go-micro framework. The service will automatically be discovered via the registry (mdns by default).
+
+Example service:
+```bash
+cd examples/mcp/hello
+go run main.go
+```
+
+## List Available Tools
+
+### Human-readable list
+```bash
+micro mcp list
+```
+
+Output:
+```
+Available MCP Tools:
+
+Service: greeter
+  • greeter.Greeter.SayHello
+
+Total: 1 tools
+```
+
+### JSON output
+```bash
+micro mcp list --json
+```
+
+Output:
+```json
+{
+  "count": 1,
+  "tools": [
+    {
+      "description": "Call SayHello on greeter service",

+      "name": "greeter.Greeter.SayHello",
+      "service": "greeter"
+    }
+  ]
+}
+```
+
+## Test a Tool
+
+### Basic test
+```bash
+micro mcp test greeter.Greeter.SayHello '{"name": "Alice"}'
+```
+
+Output:
+```
+Testing tool: greeter.Greeter.SayHello
+Service: greeter
+Endpoint: Greeter.SayHello
+Input: {"name": "Alice"}
+
+✅ Call successful!
+
+Response:
+{
+  "message": "Hello Alice!"
+}
+```
+
+### Test with default empty input
+```bash
+micro mcp test greeter.Greeter.SayHello
+```
+
+This will call the tool with an empty JSON object `{}`.

+# agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION)
+# agent.run('Your query here')
+```
+
+Save to file:
+```bash
+micro mcp export langchain --output langchain_tools.py
+```
+
+### Export to OpenAPI 3.0
+
+Generate an OpenAPI specification:
+
+```bash
+micro mcp export openapi
+```
+
+Output:
+```json
+{
+  "components": {
+    "securitySchemes": {
+      "bearerAuth": {

+  "paths": {
+    "/mcp/call/greeter/Greeter/SayHello": {
+      "post": {

+    {
+      "description": "MCP Gateway",
+      "url": "http://localhost:3000"
+    }
+  ]
+}
+```
+
+Save to file:
+```bash
+micro mcp export openapi --output openapi.json
+```
+
+### Export to raw JSON
+
+Export raw tool definitions:
+
+```bash
+micro mcp export json
+```
+
+This is similar to `micro mcp docs --format json` but specifically for export purposes.
+
+Save to file:
+```bash
+micro mcp export json --output tools.json
+```
+
+## Using with Different Registries
+
+By default, the commands use mdns registry. You can specify a different registry:
+
+```bash
+# Using consul
+micro mcp list --registry consul --registry_address consul:8500
+
+# Using etcd
+micro mcp list --registry etcd --registry_address etcd:2379
+```
+
+## Integration Examples
+
+### Using LangChain Export with Claude
+
+1. Export your tools to LangChain format:
+```bash
+micro mcp export langchain --output my_tools.py
+```
+
+2. Use in your Python agent:
+```python
+from my_tools import tools
+from langchain.agents import initialize_agent, AgentType
+from langchain.chat_models import ChatAnthropic
+
+llm = ChatAnthropic(model="claude-3-sonnet-20240229")
+agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION)
+
+result = agent.run("Greet Alice")
+print(result)
+```
+
+### Using OpenAPI Export with GPT
+
+1. Export to OpenAPI:
+```bash
+micro mcp export openapi --output openapi.json
+```
+
+2. Upload to ChatGPT as a custom GPT action or use with OpenAI Assistants API.
+
+### Documentation for AI Agents
+
+Generate documentation that AI agents can read to understand your services:
+
+```bash
+micro mcp docs --format json --output service-catalog.json
+```
+
+This JSON file can be fed to AI agents for service discovery and understanding.
+
+## Advanced Usage
+
+### Piping and Processing
+
+You can pipe the output to other tools:
+
+```bash
+# Count tools per service
+micro mcp list --json | jq '.tools | group_by(.service) | map({service: .[0].service, count: length})'
+
+# Extract all tool names
+micro mcp list --json | jq -r '.tools[].name'
+
+# Filter tools by service
+micro mcp list --json | jq '.tools[] | select(.service == "greeter")'
+```
+
+### Monitoring and CI/CD
+
+Use these commands in your CI/CD pipeline:
+
+```bash
+# Validate all services are discoverable
+SERVICE_COUNT=$(micro mcp list --json | jq '.count')
+if [ "$SERVICE_COUNT" -lt 5 ]; then
+  echo "Error: Expected at least 5 services, found $SERVICE_COUNT"
+  exit 1
+fi
+
+# Generate documentation on each deployment
+micro mcp docs --output docs/mcp-services.md
+git add docs/mcp-services.md
+git commit -m "Update MCP service documentation"
+```
+
+### Testing in Development
+
+Create a script to test all your tools:
+
+```bash
+#!/bin/bash
+# test-all-tools.sh
+
+TOOLS=$(micro mcp list --json | jq -r '.tools[].name')
+
+for tool in $TOOLS; do
+  echo "Testing $tool..."
+  micro mcp test "$tool" "{}" || echo "Failed: $tool"
+done
+```
+
+## Troubleshooting
+
+### No tools found
+
+If `micro mcp list` shows 0 tools:
+
+1. Verify services are running:
+```bash
+ps aux | grep "your-service"
+```
+
+2. Check registry (mdns might need time to discover):
+```bash
+# Wait a few seconds and try again
+sleep 3
+micro mcp list
+```
+
+3. Use a different registry if mdns is unreliable:
+```bash
+# Start services with consul
+micro --registry consul server
+
+# List with consul
+micro mcp list --registry consul
+```
+
+### Service not responding in tests
+
+If `micro mcp test` fails:
+
+1. Verify the tool name is correct:
+```bash
+micro mcp list
+```
+
+2. Check the JSON input format:
+```bash
+# Invalid
+micro mcp test service.Handler.Method '{invalid}'
+
+# Valid
+micro mcp test service.Handler.Method '{"key": "value"}'
+```
+
+3. Check service logs for errors.

+[![License](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)
+
+Official LangChain integration for Go Micro services. This package enables LangChain agents to discover and call Go Micro microservices through the Model Context Protocol (MCP).
+
+## Features
+
+- 🔍 **Automatic Service Discovery** - Discovers available services from MCP gateway
+- 🛠️ **Dynamic Tool Generation** - Converts service endpoints into LangChain tools
+- 📝 **Rich Descriptions** - Uses service metadata for accurate tool descriptions
+- 🔐 **Authentication Support** - Bearer token auth with scope-based permissions
+- ⚡ **Type-Safe** - Fully typed with Python 3.8+ type hints
+- 🎯 **Easy Integration** - Works with any LangChain agent
+
+## Installation
+
+```bash
+pip install langchain-go-micro
+```
+
+## Quick Start
+
+### 1. Start Your Go Micro Services
+
+```bash
+# Start MCP gateway
+micro mcp serve --address :3000
+```
+
+### 2. Create LangChain Agent
+
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent, AgentType
+from langchain_openai import ChatOpenAI
+
+# Initialize toolkit from MCP gateway
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Create agent
+llm = ChatOpenAI(model="gpt-4")
+agent = initialize_agent(
+    toolkit.get_tools(),
+    llm,
+    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
+    verbose=True
+)
+
+# Use the agent!
+result = agent.run("Create a user named Alice with email alice@example.com")
+print(result)
+```
+
+## Usage Examples
+
+### Basic Tool Discovery
+
+```python
+from langchain_go_micro import GoMicroToolkit
+
+# Connect to MCP gateway
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# List available tools
+for tool in toolkit.get_tools():
+    print(f"Tool: {tool.name}")
+    print(f"Description: {tool.description}")
+    print()
+```
+
+### Authentication
+
+```python
+from langchain_go_micro import GoMicroToolkit
+
+# Create toolkit with authentication
+toolkit = GoMicroToolkit.from_gateway(
+    gateway_url="http://localhost:3000",
+    auth_token="your-bearer-token"
+)
+
+# Tools will automatically use the auth token
+tools = toolkit.get_tools()
+```
+
+### Filter Tools by Service
+
+```python
+from langchain_go_micro import GoMicroToolkit
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Get only user service tools
+user_tools = toolkit.get_tools(service_filter="users")
+
+# Get tools matching a pattern
+blog_tools = toolkit.get_tools(name_pattern="blog.*")
+```
+
+### Custom Tool Selection
+
+```python
+from langchain_go_micro import GoMicroToolkit
+
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Select specific tools
+selected_tools = toolkit.get_tools(
+    include=["users.Users.Get", "users.Users.Create"]
+)
+
+# Exclude certain tools
+filtered_tools = toolkit.get_tools(
+    exclude=["users.Users.Delete"]
+)
+```
+
+### Multi-Agent Workflows
+
+```python
+from langchain_go_micro import GoMicroToolkit
+from langchain.agents import initialize_agent, AgentType
+from langchain_openai import ChatOpenAI
+
+# Create specialized agents for different services
+toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+
+# Agent 1: User management
+user_agent = initialize_agent(
+    toolkit.get_tools(service_filter="users"),
+    ChatOpenAI(model="gpt-4"),
+    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION
+)
+
+# Agent 2: Order processing
+order_agent = initialize_agent(
+    toolkit.get_tools(service_filter="orders"),
+    ChatOpenAI(model="gpt-4"),
+    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION
+)
+
+# Coordinate between agents
+user = user_agent.run("Create user Alice")
+order = order_agent.run(f"Create order for user {user['id']}")
+```
+
+### Error Handling
+
+```python
+from langchain_go_micro import GoMicroToolkit, GoMicroError
+
+try:
+    toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")
+    tools = toolkit.get_tools()
+except GoMicroError as e:
+    print(f"Error: {e}")
+    # Handle error (gateway unreachable, auth failed, etc.)
+```
+
+### Advanced Configuration
+
+```python
+from langchain_go_micro import GoMicroToolkit, GoMicroConfig
+
+config = GoMicroConfig(
+    gateway_url="http://localhost:3000",
+    auth_token="your-token",
+    timeout=30,  # Request timeout in seconds
+    retry_count=3,  # Number of retries on failure
+    retry_delay=1.0,  # Delay between retries
+    verify_ssl=True,  # SSL certificate verification
+)
+
+toolkit = GoMicroToolkit(config)
+tools = toolkit.get_tools()
+```

+## Troubleshooting
+
+### Gateway Connection Issues
+
+If you can't connect to the MCP gateway:
+
+1. Verify the gateway is running:
+```bash
+curl http://localhost:3000/health
+```
+
+2. Check the gateway URL is correct
+3. Verify firewall settings
+
+### Authentication Errors
+
+If you get authentication errors:
+
+1. Verify your token is valid
+2. Check the token has required scopes
+3. Review gateway logs for details
+
+### Tool Discovery Issues
+
+If tools aren't being discovered:
+
+1. List services from gateway:
+```bash
+curl http://localhost:3000/mcp/tools
+```
+
+2. Verify services are registered
+3. Check service metadata is correct

+# Model Package
+
+The `model` package provides a simple, high-level interface for AI model providers like Anthropic Claude and OpenAI GPT.
+
+## Interface
+
+The Model interface follows the same patterns as other go-micro packages (Registry, Client, Broker):
+
+```go
+type Model interface {
+    Init(...Option) error
+    Options() Options
+    Generate(ctx context.Context, req *Request, opts ...GenerateOption) (*Response, error)
+    Stream(ctx context.Context, req *Request, opts ...GenerateOption) (Stream, error)
+    String() string
+}
+```
+
+## Quick Start
+
+```go
+import (
+    "context"
+    "go-micro.dev/v5/model"
+    _ "go-micro.dev/v5/model/anthropic"
+    _ "go-micro.dev/v5/model/openai"
+)
+
+// Create a model
+m := model.New("openai",
+    model.WithAPIKey("your-api-key"),
+    model.WithModel("gpt-4o"),
+)
+
+// Generate a response
+req := &model.Request{
+    Prompt:       "What is Go?",
+    SystemPrompt: "You are a helpful programming assistant",
+}
+
+resp, err := m.Generate(context.Background(), req)
+if err != nil {
+    log.Fatal(err)
+}
+
+fmt.Println(resp.Reply)
+```
+
+## Options
+
+Configure the model using functional options:
+
+```go
+m := model.New("anthropic",
+    model.WithAPIKey("your-key"),              // Required
+    model.WithModel("claude-sonnet-4-20250514"), // Optional, uses provider default
+    model.WithBaseURL("https://api.anthropic.com"), // Optional, uses provider default
+)
+```
+
+You can also update options after creation:
+
+```go
+m.Init(
+    model.WithModel("gpt-4o-mini"),
+    model.WithAPIKey("new-key"),
+)
+```
+
+## Using Tools
+
+The model can automatically execute tool calls when provided with a tool handler:
+
+```go
+// Define a tool handler
+toolHandler := func(name string, input map[string]any) (result any, content string) {
+    // Execute the tool and return results
+    switch name {
+    case "get_weather":
+        return map[string]string{"temp": "72F"}, `{"temp": "72F"}`
+    default:
+        return nil, `{"error": "unknown tool"}`
+    }
+}
+
+// Create model with tool handler
+m := model.New("openai",
+    model.WithAPIKey("your-key"),
+    model.WithToolHandler(toolHandler),
+)
+
+// Provide tools in the request
+req := &model.Request{
+    Prompt: "What's the weather?",
+    SystemPrompt: "You are a helpful assistant",
+    Tools: []model.Tool{
+        {
+            Name:        "get_weather",
+            Description: "Get current weather",
+            Properties: map[string]any{
+                "location": map[string]any{
+                    "type": "string",
+                    "description": "City name",
+                },
+            },
+        },
+    },
+}
+
+// Generate will automatically call tools and return final answer
+resp, err := m.Generate(context.Background(), req)
+fmt.Println(resp.Answer) // Final answer after tool execution
+```
+
+## Response Structure
+
+```go
+type Response struct {
+    Reply     string      // Initial reply from model
+    ToolCalls []ToolCall  // Tools the model wants to call
+    Answer    string      // Final answer (after tool execution if handler provided)
+}
+```
+
+- `Reply`: The model's first response
+- `ToolCalls`: List of tools the model requested (if any)
+- `Answer`: The final answer after tools are executed (only set if ToolHandler is provided)
+
+## Supported Providers
+
+### Anthropic Claude
+
+```go
+m := model.New("anthropic",
+    model.WithAPIKey("sk-ant-..."),
+    model.WithModel("claude-sonnet-4-20250514"), // default
+)
+```
+
+Default model: `claude-sonnet-4-20250514`  
+Default base URL: `https://api.anthropic.com`
+
+### OpenAI GPT
+
+```go
+m := model.New("openai",
+    model.WithAPIKey("sk-..."),
+    model.WithModel("gpt-4o"), // default
+)
+```
+
+Default model: `gpt-4o`  
+Default base URL: `https://api.openai.com`
+
+## Auto-Detection
+
+Use `AutoDetectProvider()` to detect the provider from a base URL:
+
+```go
+provider := model.AutoDetectProvider("https://api.anthropic.com")
+// Returns "anthropic"
+
+m := model.New(provider, model.WithAPIKey("..."))
+```
+
+## Adding a New Provider
+
+1. Create a new package under `model/`:
+
+```go
+package myprovider
+
+import "go-micro.dev/v5/model"
+
+func init() {
+    model.Register("myprovider", func(opts ...model.Option) model.Model {
+        return NewProvider(opts...)
+    })
+}
+
+type Provider struct {
+    opts model.Options
+}
+
+func NewProvider(opts ...model.Option) *Provider {
+    options := model.NewOptions(opts...)
+    // Set defaults
+    if options.Model == "" {
+        options.Model = "my-default-model"
+    }
+    if options.BaseURL == "" {
+        options.BaseURL = "https://api.myprovider.com"
+    }
+    return &Provider{opts: options}
+}
+
+func (p *Provider) Init(opts ...model.Option) error {
+    for _, o := range opts {
+        o(&p.opts)
+    }
+    return nil
+}
+
+func (p *Provider) Options() model.Options {
+    return p.opts
+}
+
+func (p *Provider) String() string {
+    return "myprovider"
+}
+
+func (p *Provider) Generate(ctx context.Context, req *model.Request, opts ...model.GenerateOption) (*model.Response, error) {
+    // Implement your provider logic
+    // - Build API request
+    // - Make HTTP call
+    // - Parse response
+    // - Handle tools if ToolHandler is set
+    return &model.Response{}, nil
+}
+
+func (p *Provider) Stream(ctx context.Context, req *model.Request, opts ...model.GenerateOption) (model.Stream, error) {
+    return nil, fmt.Errorf("streaming not implemented")
+}
+```
+
+2. Import your provider:
+
+```go
+import _ "go-micro.dev/v5/model/myprovider"
+```
+
+## Comparison with Other Packages
+
+The model package follows the same patterns as other go-micro packages:
+
+**Registry:**
+```go
+r := registry.NewRegistry(registry.Addrs("..."))
+r.Register(service)
+```
+
+**Client:**
+```go
+c := client.NewClient(client.Retries(3))
+c.Call(ctx, req, rsp)
+```
+
+**Model:**
+```go
+m := model.New("openai", model.WithAPIKey("..."))
+m.Generate(ctx, req)
+```
+
+All use:
+- `Init()` to update options
+- `Options()` to get current options
+- `String()` to get the implementation name
+- Functional options pattern
+
+## Testing
+
+```bash
+go test ./model/...
+```
+
+## Examples
+
+See the [server implementation](../../cmd/micro/server/server.go) for a complete example of using the model package with tool execution.
