+# MCP Provider Integration Guide
+
+## Overview
+
+Task Master provides a **unified MCP provider** for AI operations:
+
+**MCP Provider** (`mcp`) - Modern AI SDK-compatible provider with full structured object generation support
+
+The MCP provider enables Task Master to act as an MCP client, using MCP servers as AI providers alongside traditional API-based providers. This integration follows the existing provider pattern and supports all standard AI operations including structured object generation for PRD parsing and task creation.
+
+## MCP Provider Features
+
+The **MCP Provider** (`mcp`) provides:
+
+✅ **Full AI SDK Compatibility** - Complete LanguageModelV1 interface implementation  
+✅ **Structured Object Generation** - Schema-driven outputs for PRD parsing and task creation  
+✅ **Enhanced Error Handling** - Robust JSON extraction and validation  
+✅ **Session Management** - Automatic session detection and context handling  
+✅ **Schema Validation** - Type-safe object generation with Zod validation  
+
+### Quick Setup
+
+```bash
+# Set MCP provider for main role  
+task-master models set-main --provider mcp --model claude-3-5-sonnet-20241022
+```
+
+For detailed information, see [MCP Provider Documentation](mcp-provider.md).
+
+## What is MCP Provider?
+
+The MCP provider allows Task Master to:
+- Connect to MCP servers/tools as AI providers
+- Use session-based authentication instead of API keys
+- Map AI operations to MCP tool calls
+- Integrate with existing role-based provider assignment

+- **`mcp-sampling`** - Uses MCP client's sampling capability for text generation
+
+## Session Requirements
+
+The MCP provider requires an active MCP session with sampling capabilities:
+
+```javascript
+session: {
+  clientCapabilities: {
+    sampling: {} // Client supports sampling requests
+  }
+}
+```
+
+## Usage Examples
+
+### Basic Text Generation
+
+```javascript
+import { generateTextService } from './scripts/modules/ai-services-unified.js';
+
+const result = await generateTextService({
+  role: 'main',
+  session: mcpSession, // Required for MCP provider
+  prompt: 'Explain MCP integration',
+  systemPrompt: 'You are a helpful AI assistant'
+});
+
+console.log(result.text);
+```
+
+### Structured Object Generation
+
+```javascript
+import { generateObjectService } from './scripts/modules/ai-services-unified.js';
+
+const result = await generateObjectService({
+  role: 'main',
+  session: mcpSession,
+  prompt: 'Create a task breakdown',
+  schema: {
+    type: 'object',
+    properties: {
+      tasks: {
+        type: 'array',
+        items: { type: 'string' }
+      }
+    }
+  }
+});
+
+console.log(result.object);
+```
+
+### Research Operations
+
+```javascript
+const research = await generateTextService({
+  role: 'research',
+  session: mcpSession,
+  prompt: 'Research the latest developments in AI',
+  systemPrompt: 'You are a research assistant'
+});
+```
+
+## CLI Integration
+
+The MCP provider works seamlessly with Task Master CLI commands when running in an MCP context:
+
+```bash
+# Generate tasks using MCP provider (if configured as main)
+task-master add-task "Implement user authentication"
+
+# Research using MCP provider (if configured as research)
+task-master research "OAuth 2.0 best practices"
+
+# Parse PRD using MCP provider
+task-master parse-prd requirements.txt
+```
+
+## Architecture Details
+
+### Provider Architecture
+**MCPProvider** (`mcp-server/src/providers/mcp-provider.js`)
+   - Modern AI SDK-compliant provider for Task Master's MCP server
+   - Auto-registers when MCP sessions connect to Task Master
+   - Enables Task Master to use MCP sessions for AI operations
+   - Supports both text generation and structured object generation
+
+### Auto-Registration Process
+
+When running as an MCP server, Task Master automatically:
+
+```javascript
+// On MCP session connect
+server.on("connect", (event) => {
+  // Check session capabilities
+  if (session.clientCapabilities?.sampling) {
+    // Create and register MCP provider
+    const mcpProvider = new MCPProvider();
+    mcpProvider.setSession(session);
+    
+    // Auto-register with provider registry
+    providerRegistry.registerProvider('mcp', mcpProvider);
+  }
+});
+```
+
+This enables seamless self-referential AI operations within MCP contexts.
+
+### Provider Pattern Integration
+
+The MCP provider follows the same pattern as other providers:
+
+```javascript
+class MCPProvider extends BaseAIProvider {
+  // Implements generateText, generateObject
+  // Uses session context instead of API keys
+  // Maps operations to MCP sampling requests
+}
+```
+
+### Session Detection
+
+The provider automatically detects MCP sampling capability when sessions connect:
+
+```javascript
+// On MCP session connect
+if (session.clientCapabilities?.sampling) {
+  // Auto-register MCP provider for use
+  const mcpProvider = new MCPProvider();
+  mcpProvider.setSession(session);
+}
+```
+
+### Sampling Integration
+
+AI operations use MCP sampling with different levels of support:
+
+- `generateText()` → MCP `requestSampling()` with messages (2-minute timeout) ✅ **Full Support**
+- `streamText()` → **Limited/No Support** ⚠️ See streaming limitations below
+- `generateObject()` → MCP `requestSampling()` with JSON schema instructions (2-minute timeout) ✅ **Full Support**
+
+**Timeout Configuration**: All MCP sampling requests use a 2-minute (120,000ms) timeout to accommodate complex AI operations.
+
+#### Streaming Text Limitations ⚠️
+
+**Important**: The MCP provider has **no support** for text streaming:
+
+**MCPProvider**:
+- **❌ No Streaming Support**: Throws error "MCP Provider does not support streaming text, use generateText instead"  
+- **Solution**: Always use `generateText()` instead of `streamText()` with this provider
+
+**Recommendation**: For streaming functionality, configure a non-MCP fallback provider (like Anthropic or OpenAI) in your fallback role.
+
+### Error Handling
+
+The MCP provider includes comprehensive error handling:
+
+- Session validation errors (checks for `clientCapabilities.sampling`)
+- MCP sampling request failures
+- JSON parsing errors (for structured output)
+- Automatic fallback to other providers
+
+### Best Practices
+
+### 1. Configure Fallbacks
+
+Always configure a non-MCP fallback provider, especially for streaming operations:
+
+```json
+{
+  "models": {
+    "main": {
+      "provider": "mcp",
+      "modelId": "mcp-sampling"
+    },
+    "fallback": {
+      "provider": "anthropic",
+      "modelId": "claude-3-5-sonnet-20241022"
+    }
+  }
+}
+```
+
+### 2. Avoid Streaming with MCP
+
+**Do not use `streamTextService()` with MCP provider**. Use `generateTextService()` instead:
+
+```javascript
+// ❌ Don't do this with MCP provider
+const result = await streamTextService({
+  role: 'main', // MCP provider
+  session: mcpSession,
+  prompt: 'Generate content'
+});
+
+// ✅ Do this instead
+const result = await generateTextService({
+  role: 'main', // MCP provider
+  session: mcpSession,
+  prompt: 'Generate content'
+});
+```
+
+### 3. Session Management
+
+Ensure your MCP session remains active throughout Task Master operations:
+
+```javascript
+// Check session health before operations
+if (!session || !session.capabilities) {
+  throw new Error('MCP session not available');
+}
+```
+
+### 4. Tool Availability
+
+Verify required capabilities are available in your MCP session:
+
+```javascript
+// Check session health and capabilities
+if (session && session.clientCapabilities && session.clientCapabilities.sampling) {
+  console.log('MCP sampling available');
+} else {
+  console.log('MCP sampling not available');
+}
+```
+
+### 5. Error Recovery
+
+Handle MCP-specific errors gracefully:
+
+```javascript
+try {
+  const result = await generateTextService({
+    role: 'main',
+    session: mcpSession,
+    prompt: 'Generate content'
+  });
+} catch (error) {
+  if (error.message.includes('MCP')) {
+    // Handle MCP-specific error
+    console.log('MCP error, falling back to alternate provider');
+  }
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"MCP provider requires session context"**
+   - Ensure `session` parameter is passed to service calls
+   - Verify session has proper structure
+   - Check that you're running in an MCP environment
+
+2. **"MCP session must have client sampling capabilities"**
+   - Check that `session.clientCapabilities.sampling` exists
+   - Verify session has `requestSampling()` method
+   - Ensure MCP client supports sampling feature
+
+3. **"MCP Provider does not support streaming text, use generateText instead"**
+   - **Common Error**: Occurs when calling `streamTextService()` with MCP provider
+   - **Solution**: Use `generateTextService()` instead of `streamTextService()`
+   - **Alternative**: Configure a non-MCP fallback provider for streaming operations
+
+4. **"MCP sampling failed"** or **Timeout errors**
+   - Check MCP client is responding to sampling requests
+   - Verify session is still active and connected
+   - Consider if request complexity requires longer processing time
+   - Check for network connectivity issues
+
+5. **"Model ID is required for MCP Remote Provider"**
+   - Ensure `modelId` is specified in configuration
+   - Use `mcp-sampling` as the standard model ID
+   - Verify provider configuration is properly loaded
+
+6. **Auto-registration failures**
+   - Check that MCP session has required sampling capabilities
+   - Verify server event listeners are properly configured
+   - Look for provider registry initialization issues
+
+### Streaming-Related Issues
+
+**Error**: `streamTextService()` calls fail with MCP provider
+**Cause**: MCP provider has no streaming support
+**Solutions**:
+- Use `generateTextService()` for all MCP-based text generation
+- Configure non-MCP fallback providers for streaming requirements
+- Check your provider configuration to ensure fallback chain includes streaming-capable providers
+
+### Debug Mode
+
+Enable debug logging to see MCP provider operations:
+
+```javascript
+// Set debug flag in config or environment
+process.env.DEBUG = 'true';
+
+// Or in .taskmasterconfig
+{
+  "debug": true,
+  "models": { /* ... */ }
+}
+```
+
+### Testing MCP Integration
+
+Test MCP provider functionality:
+
+```javascript
+// Check if MCP provider is properly registered
+import { MCPProvider } from './mcp-server/src/providers/mcp-provider.js';
+
+// Test session capabilities
+if (session && session.clientCapabilities && session.clientCapabilities.sampling) {
+  console.log('MCP sampling available');
+  
+  // Test provider creation
+  const provider = new MCPProvider();
+  provider.setSession(session);
+  console.log('MCP provider created successfully');
+} else {
+  console.log('MCP session lacks required capabilities');
+}
+```
+
+## Integration with Development Tools

+2. Configure Task Master MCP server endpoint
+3. Use MCP provider for enhanced AI-driven development
+
+## Advanced Configuration
+
+### Custom Tool Mapping
+
+Advanced users can use MCP sampling for all roles:
+
+```javascript
+// MCP sampling for all roles
+{
+  "models": {
+    "main": {
+      "provider": "mcp",
+      "modelId": "mcp-sampling"
+    }
+  }
+}
+```
+
+### Role-Specific Configuration
+
+Configure MCP sampling for different roles:
+
+```json
+{
+  "models": {
+    "main": {
+      "provider": "mcp",
+      "modelId": "mcp-sampling"
+    },
+    "research": {
+      "provider": "mcp", 
+      "modelId": "mcp-sampling"
+    },
+    "fallback": {
+      "provider": "mcp",
+      "modelId": "backup-server:simple-generation"
+    }
+  }
+}
+```
+
+### API Reference
+
+### MCPProvider Methods
+
+- `generateText(params)` - Generate text using MCP sampling ✅ **Supported**
+- `streamText(params)` - Stream text ❌ **Not supported** (throws error)
+- `generateObject(params)` - Generate structured objects ✅ **Supported**
+- `setSession(session)` - Update provider session
+- `validateAuth(params)` - Validate session capabilities
+- `getClient()` - Returns null (not applicable for MCP)
+
+### Required Parameters
+
+All MCP operations require:
+- `session` - Active MCP session object (auto-provided when registered)
+- `modelId` - MCP model identifier (typically "mcp-sampling")
+- `messages` - Array of message objects
+
+### Optional Parameters
+
+- `temperature` - Creativity control (if supported by MCP client)
+- `maxTokens` - Maximum response length (if supported)
+- `schema` - JSON schema for structured output (generateObject only)
+
+## Security Considerations
+
+1. **Session Security**: MCP sessions should be properly authenticated
+2. **Server Validation**: Only connect to trusted MCP servers
+3. **Data Privacy**: Ensure MCP clients handle data according to your privacy requirements
+4. **Error Exposure**: Be careful not to expose sensitive session information in error messages
+
+## Future Enhancements
+
+Planned improvements for MCP provider:
+
+1. **Native Streaming Support** - True streaming for compatible MCP clients (requires MCP protocol updates)
+2. **Enhanced Session Monitoring** - Automatic session validation and recovery
+3. **Performance Optimization** - Caching and connection pooling
+4. **Advanced Error Recovery** - Intelligent retry and fallback strategies
+
+**Note**: True streaming support depends on future MCP protocol enhancements. Current implementation provides text generation without streaming capabilities.

+                        Text Generation + Object Generation
+```
+
+## Implementation Details
+
+### Provider Registration
+
+The MCP server registers **both** providers when a client connects:
+
+```javascript
+// mcp-server/src/index.js
+registerRemoteProvider(session) {
+  if (session?.clientCapabilities?.sampling) {
+    // Register existing provider
+    // Register unified MCP provider
+    const mcpProvider = new MCPProvider();
+    mcpProvider.setSession(session);
+    
+    const providerRegistry = ProviderRegistry.getInstance();
+    providerRegistry.registerProvider('mcp', mcpProvider);
+  }
+}
+```
+
+### AI Services Integration
+
+The AI services layer includes the new provider:
+
+```javascript
+// scripts/modules/ai-services-unified.js
+const PROVIDERS = {
+  // ... other providers
+  'mcp': () => {
+    const providerRegistry = ProviderRegistry.getInstance();
+    return providerRegistry.getProvider('mcp');
+  }
+};
+```
+
+### Message Conversion
+
+The provider converts between AI SDK and MCP formats:
+
+```javascript
+// AI SDK prompt → MCP sampling format
+const { messages, systemPrompt } = convertToMCPFormat(options.prompt);
+
+// MCP response → AI SDK format
+const result = convertFromMCPFormat(response);
+```
+
+## Structured Object Generation (generateObject)
+
+### Overview
+
+The MCP Provider includes full support for structured object generation, enabling schema-driven features like PRD parsing, task creation, and any operations requiring validated JSON outputs.
+
+### Architecture
+
+The generateObject implementation includes:
+
+1. **Schema-to-Instructions Conversion** (`schema-converter.js`)
+   - Converts Zod schemas to natural language instructions
+   - Generates example outputs to guide AI responses
+   - Handles complex nested schemas and validation requirements
+
+2. **JSON Extraction Pipeline** (`json-extractor.js`)
+   - Multiple extraction strategies for robust JSON parsing
+   - Handles code blocks, malformed JSON, and various response formats
+   - Fallback mechanisms for maximum reliability
+
+3. **Validation System**
+   - Complete schema validation using Zod
+   - Detailed error reporting for failed validations
+   - Type-safe object generation
+
+### Implementation Details
+
+#### doGenerateObject Method
+
+The `MCPLanguageModel` class implements the AI SDK's `doGenerateObject` method:
+
+```javascript
+async doGenerateObject({ schema, objectName, prompt, ...options }) {
+  // Convert schema to instructions
+  const instructions = convertSchemaToInstructions(schema, objectName);
+  
+  // Enhance prompt with structured output requirements
+  const enhancedPrompt = enhancePromptForObjectGeneration(prompt, instructions);
+  
+  // Generate response via MCP sampling
+  const response = await this.doGenerate({ prompt: enhancedPrompt, ...options });
+  
+  // Extract and validate JSON
+  const extractedJson = extractJsonFromResponse(response.text);
+  const validatedObject = schema.parse(extractedJson);
+  
+  return {
+    object: validatedObject,
+    usage: response.usage,
+    finishReason: response.finishReason
+  };
+}
+```
+
+#### AI SDK Compatibility
+
+The provider includes required properties for AI SDK object generation:
+
+```javascript
+class MCPLanguageModel {
+  get defaultObjectGenerationMode() {
+    return 'tool';
+  }
+  
+  get supportsStructuredOutputs() {
+    return true;
+  }
+  
+  // ... doGenerateObject implementation
+}
+```
+
+### Usage Examples
+
+#### PRD Parsing
+
+```javascript
+import { z } from 'zod';
+
+const taskSchema = z.object({
+  title: z.string(),
+  description: z.string(),
+  priority: z.enum(['high', 'medium', 'low']),
+  dependencies: z.array(z.number()).optional()
+});
+
+const result = await generateObject({
+  model: mcpModel,
+  schema: taskSchema,
+  prompt: 'Parse this PRD section into a task: [PRD content]'
+});
+
+console.log(result.object); // Validated task object
+```
+
+#### Task Creation
+
+```javascript
+const taskCreationSchema = z.object({
+  task: z.object({
+    title: z.string(),
+    description: z.string(),
+    details: z.string(),
+    testStrategy: z.string(),
+    priority: z.enum(['high', 'medium', 'low']),
+    dependencies: z.array(z.number()).optional()
+  })
+});
+
+const result = await generateObject({
+  model: mcpModel,
+  schema: taskCreationSchema,
+  prompt: 'Create a comprehensive task for implementing user authentication'
+});
+```
+
+### Error Handling
+
+The implementation provides comprehensive error handling:
+
+- **Schema Validation Errors**: Detailed Zod validation messages
+- **JSON Extraction Failures**: Fallback strategies and clear error reporting
+- **MCP Communication Errors**: Proper error mapping and recovery
+- **Timeout Handling**: Configurable timeouts for long-running operations
+
+### Testing
+
+The generateObject functionality is fully tested:
+
+```bash
+# Test object generation
+npm test -- --grep "generateObject"
+
+# Test with actual MCP session
+node test-object-generation.js
+```
+
+### Supported Features
