# MCP Sampling Implementation Summary **Version:** 1.14.0 **Date:** 2025-10-24 **Feature:** MCP Sampling (AI-Powered Tools) **Status:** ✅ Complete and Ready for Testing --- ## 🎯 What Was Implemented We've successfully implemented **MCP Sampling support** for the Cisco Support MCP Server, adding 5 new AI-powered tools that leverage the Model Context Protocol's sampling capability. ### Key Changes 1. **SDK Update**: Upgraded from v1.13.0 to v1.20.2 2. **New Utilities**: Created `src/utils/sampling.ts` with helper functions 3. **New Tools**: Created `src/apis/sampling-tools.ts` with 5 AI-powered tools 4. **API Integration**: Added sampling to the API registry system 5. **Documentation**: Comprehensive updates to CLAUDE.md 6. **Version Bump**: Updated to v1.14.0 --- ## 🤖 New AI-Powered Tools (5 tools) ### 1. `resolve_product_name` 🔍 **Purpose:** Convert natural language product descriptions to Cisco product IDs **Input:** ```json { "product_description": "Catalyst 9200 24-port switch with PoE" } ``` **Output:** - Product ID: `C9200-24P` - Usage suggestions for next steps **Use Case:** When users describe products conversationally instead of using technical IDs --- ### 2. `categorize_bug` 🏷️ **Purpose:** AI-powered bug analysis and categorization **Input:** ```json { "bug_description": "Router crashes during high CPU load with memory leak" } ``` **Output:** ```json { "severity": "high", "impact": "crash-memory-leak", "category": "routing" } ``` **Use Case:** Quick triage and classification of unfamiliar bugs --- ### 3. `analyze_upgrade_risk_with_ai` ⚠️ **Purpose:** Comprehensive AI analysis of software upgrade risks **Input:** ```json { "product_id": "C9300-24P", "current_version": "17.9.1", "target_version": "17.12.3" } ``` **Output:** - Risk level assessment (Low/Medium/High/Critical) - Key issues to be aware of - Recommended actions - Specific prerequisites and precautions **Use Case:** Planning software upgrades with detailed risk analysis --- ### 4. `summarize_bugs_with_ai` 📊 **Purpose:** Generate natural language summaries of bug search results **Input:** ```json { "bug_ids": "CSCvi12345,CSCvi12346,CSCvi12347", "search_context": "ISR4431 upgrade planning" } ``` **Output:** - Overall findings (bug count, severity distribution) - Critical issues highlighted - Key recommendations - Human-readable summary **Use Case:** Executive summaries, reports, and quick overviews --- ### 5. `extract_product_query` 🔎 **Purpose:** Parse natural language queries into structured search parameters **Input:** ```json { "natural_query": "Show me critical bugs for Catalyst 9200 running 17.9.1" } ``` **Output:** ```json { "productSeries": "Cisco Catalyst 9200 Series", "version": "17.9.1", "severity": 1, "keywords": ["critical", "bugs"] } ``` **Use Case:** Conversational bug searches with automatic parameter extraction --- ## 🏗️ Technical Architecture ### Sampling Utilities (`src/utils/sampling.ts`) **Core Functions:** 1. `clientSupportsSampling()` - Check if client has sampling capability 2. `requestSampling()` - Main sampling request function 3. `resolveProductName()` - Product name resolution 4. `categorizeBug()` - Bug categorization logic 5. `analyzeUpgradeRisk()` - Upgrade risk analysis 6. `summarizeBugs()` - Bug summary generation 7. `extractProductQuery()` - Query parsing **Model Preferences System:** ```typescript interface ModelPreferences { intelligencePriority?: number; // 0.0-1.0 speedPriority?: number; // 0.0-1.0 costPriority?: number; // 0.0-1.0 hints?: Array<{ name?: string }>; } ``` ### Integration Points 1. **API Registry**: Sampling added as new API type 2. **Tool Handlers**: Special handling for sampling tools 3. **Server Instance**: Passed to API registry for sampling calls 4. **Error Handling**: Graceful fallback when sampling unavailable --- ## 📋 Requirements ### Client Requirements - **MCP SDK**: v1.20.2 or later - **Protocol**: MCP 2025-06-18 specification - **Capability**: Must declare `sampling` in capabilities ### Server Requirements - **Node.js**: 18+ (no change) - **TypeScript**: 5.8.3+ (no change) - **Dependencies**: @modelcontextprotocol/sdk@^1.20.2 ### Configuration **Enable sampling in Claude Desktop:** ```json { "mcpServers": { "cisco-support": { "command": "npx", "args": ["mcp-cisco-support"], "env": { "CISCO_CLIENT_ID": "your_id", "CISCO_CLIENT_SECRET": "your_secret", "SUPPORT_API": "bug,sampling" } } } } ``` **Or use sampling alone:** ```json { "SUPPORT_API": "sampling" } ``` --- ## 🔒 Security Considerations ### Built-in Safeguards 1. **No Server API Keys**: Server never requires or stores LLM API keys 2. **Client Control**: Client maintains full control over model access 3. **Human-in-Loop**: Clients should provide approval UI for sampling requests 4. **Audit Trail**: All sampling requests logged for transparency 5. **Graceful Degradation**: Tools provide helpful errors when sampling unavailable ### Best Practices - ✅ Review sampling requests before approval (client-side) - ✅ Set appropriate model preferences for each use case - ✅ Monitor sampling usage and costs (client-side) - ✅ Use lower intelligence priority for simple tasks - ✅ Implement rate limiting (client-side) --- ## 📊 Model Preference Guidelines ### Task-Based Recommendations **Product Name Resolution:** - intelligencePriority: 0.5 (moderate intelligence) - speedPriority: 0.8 (fast response important) - costPriority: 0.7 (keep costs low) - temperature: 0.1 (deterministic) **Bug Categorization:** - intelligencePriority: 0.8 (good analysis needed) - speedPriority: 0.5 (balanced) - costPriority: 0.5 (balanced) - temperature: 0.2 (mostly deterministic) **Upgrade Risk Analysis:** - intelligencePriority: 0.9 (thorough analysis critical) - speedPriority: 0.3 (can take time) - costPriority: 0.3 (quality over cost) - temperature: 0.3 (some creativity ok) **Bug Summarization:** - intelligencePriority: 0.7 (good understanding needed) - speedPriority: 0.6 (reasonably fast) - costPriority: 0.5 (balanced) - temperature: 0.4 (allow some creativity) **Query Extraction:** - intelligencePriority: 0.7 (good parsing needed) - speedPriority: 0.7 (fast response) - costPriority: 0.6 (cost-conscious) - temperature: 0.2 (deterministic parsing) --- ## 🧪 Testing ### Manual Testing Steps 1. **Check Compilation:** ```bash npm run build ``` 2. **Start Server:** ```bash SUPPORT_API=sampling npm start ``` 3. **Test with MCP Client:** ```bash # In Claude Desktop, try: "What's the product ID for a Catalyst 9200 switch?" "Categorize this bug: Router crashes during firmware upgrade" ``` ### Test Cases **Positive Tests:** - ✅ Client with sampling support receives tools - ✅ Product name resolution returns correct IDs - ✅ Bug categorization returns structured data - ✅ Upgrade analysis provides recommendations - ✅ Bug summarization generates readable text - ✅ Query extraction parses conversational input **Negative Tests:** - ✅ Client without sampling gets helpful error message - ✅ Invalid product descriptions handled gracefully - ✅ Malformed queries don't crash server - ✅ Sampling failures return error with alternatives ### Integration Testing Test with these MCP clients: - [ ] Claude Desktop (macOS/Windows) - [ ] MCP Inspector - [ ] VS Code with MCP extension - [ ] Custom HTTP clients --- ## 📈 Expected Benefits ### For End Users - **Natural Language**: Describe products and bugs conversationally - **Faster Triage**: AI categorization saves time - **Better Decisions**: Upgrade risk analysis reduces downtime - **Clear Summaries**: Understand complex bug data quickly ### For Developers - **No API Keys**: No need to manage LLM API credentials - **Flexible**: Client chooses the model and controls costs - **Extensible**: Easy to add new sampling-powered features - **Standard**: Uses official MCP specification ### Performance Impact - **Server Load**: Minimal (sampling happens client-side) - **Latency**: Depends on client's LLM provider - **Cost**: User controls via model preferences - **Fallback**: Standard tools still available --- ## 🚀 Future Enhancements ### Potential New Sampling Tools 1. **Bug Resolution Predictor**: Predict if/when a bug will be fixed 2. **Product Compatibility Checker**: AI-powered compatibility analysis 3. **Release Notes Summarizer**: Natural language release note summaries 4. **Incident Correlation**: Find related bugs across products 5. **Configuration Validator**: AI-powered config validation ### Technical Improvements 1. Add caching for common queries 2. Implement progressive sampling (try simple first, escalate if needed) 3. Add streaming support for long responses 4. Create specialized prompts per product family 5.
