Business Impact
- Strengths: Reduced losses, improved security, customer trust
- Challenges: False positive management, regulatory compliance
- ROI: 300-500% return through loss prevention
Model Context Protocol (MCP) Integration
Proposed intelligent conversational system that could transform how Checkatrade handles complex customer inquiries and tradesperson coordination. MCP servers would enable AI agents to maintain context across multiple interactions, access real-time data, and execute complex workflows that typically require human intervention.
The Core Value Proposition: MCP represents a paradigm shift from stateless interactions to persistent, context-aware AI systems. Unlike traditional chatbots that treat each interaction independently, MCP servers maintain rich contextual understanding that evolves over time, making them particularly valuable for complex service businesses like Checkatrade where customer relationships span months or years.
Current Checkatrade Pain Points MCP Could Address:
- Information Loss Between Interactions
- Problem: Customer calls back weeks later, has to re-explain their property, previous work, and preferences
- MCP Solution: Persistent memory of property details, family situations, budget constraints, and communication preferences
- Value: Reduces customer frustration, improves first-call resolution, enhances perceived service quality

Advanced Integration Capabilities:
Tool Orchestration:
- Parallel Tool Execution: MCP can call multiple tools simultaneously (search + pricing + availability)
- Sequential Dependencies: Tools can trigger other tools based on results (booking → payment → notification)
- Error Handling: Failed tool calls trigger alternative workflows or human handoff
Complex Decision Making:
- Multi-criteria Optimization: Balancing cost, timeline, quality, and customer constraints
- Dynamic Replanning: Adjusting schedules based on new requirements or constraints
- Risk Assessment: Identifying potential issues before they impact the project
Intelligent Communication:
- Progressive Disclosure: Revealing complexity gradually as customer shows interest
- Expectation Management: Clear communication about timelines, costs, and potential issues
- Proactive Updates: Automatic notifications about project progress and next steps
Detailed MCP Implementation Scenarios:
Scenario 1: Complex Problem Diagnosis
Customer: "The kitchen tap is dripping, but also the pressure upstairs is terrible,
and I think it might be connected to the work the plumber did last month."
Traditional System: Creates new plumbing inquiry, loses context about previous work
MCP System:
- Accesses previous job history (plumber visit last month)
- Understands potential connection between recent work and current issues
- Flags for quality review while addressing immediate problem
- Suggests comprehensive plumbing assessment
- Automatically notifies previous tradesperson about potential follow-up needed
Scenario 2: Multi-Phase Project Planning
Customer: "We want to renovate our bathroom, but we're not sure about the order
of work or if our budget of £8,000 is realistic."
MCP Analysis:
- Property Context: Victorian terrace, previous electrical work in 2022
- Budget Analysis: £8,000 for full bathroom renovation (flagged as potentially insufficient)
- Trade Sequencing: Electrician (safety check) → Plumber (first fix) → Tiler → Electrician (second fix)
- Risk Factors: Old property may have hidden complications
- Recommendations: Phase the work, suggest starting with electrical safety assessment
Value: Customer gets realistic timeline, proper sequencing, and budget guidance upfront
Scenario 3: Seasonal Service Opportunities
MCP Proactive Analysis:
- Customer Context: Had boiler service in March 2023, mentioned old system
- Seasonal Trigger: October arrival, heating season approaching
- Historical Pattern: Previous emergency callout in winter 2022
- Property Risk: 1960s house, original heating system
Automated Action:
- Generate proactive outreach: "Winter's approaching, and we noticed your boiler
is due for its annual service. Given the emergency repair we did in 2022,
would you like us to arrange a thorough system check?"
Technical Architecture Benefits:
Memory Persistence Across Sessions: Unlike traditional web sessions that expire, MCP maintains:
- Customer property database with evolving details
- Service history with outcomes and satisfaction scores
- Preference patterns (communication style, budget sensitivity, quality expectations)
- Seasonal patterns and proactive service opportunities
Real-Time Data Integration: MCP servers can access:
- Live tradesperson availability and location
- Dynamic pricing based on demand and customer history
- Weather data affecting job feasibility
- Regulatory updates affecting work requirements
- Material availability and pricing fluctuations
Intelligent Workflow Automation:
- Automatic quote generation considering customer context
- Smart scheduling accounting for trade dependencies

Drone-Based Roof Inspections with AI Analysis
Real-world deployment of AI-powered drone roof inspection systems addressing critical industry challenges. Roofing is the UK's most complained-about building trade, with Checkatrade declining 1 in 3 roofer applications due to quality concerns. The lack of formal licensing requirements and difficulty verifying roof work creates significant trust issues for homeowners.
Checkatrade Labs Implementation: Already deployed in Newcastle, Reading, and Oxford, with plans for national coverage. The system achieves 75% cost reduction compared to traditional surveys, delivering comprehensive roof assessments for under £100 per property.

| Component | Strengths | Weaknesses |
|---|---|---|
| Frontend: React + TypeScript | • Mature ecosystem • Excellent AI component libraries • Strong type safety for complex AI data flows | • Bundle size concerns with multiple AI SDKs • Complex state management for real-time AI interactions |
| Backend: Node.js + TypeScript | • Unified language across stack • Excellent async handling for AI API calls • Rich AI/ML library ecosystem | • Single-threaded limitations for CPU-intensive AI processing • Memory management challenges with large AI models |
| Cloud: Google Cloud Platform | • Cloud Run: Auto-scaling AI microservices • Cloud Functions: AI event triggers • Firestore: Real-time collaborative workflows | • Vendor lock-in concerns • Complex pricing for AI workloads • Limited AI-specific managed services vs. AWS/Azure |
| AI: Claude/GPT + Clinebot + Devin | • Multi-model approach reduces vendor dependency • Best-in-class reasoning and code generation • Specialized automation for development workflows | • Multiple API charges escalate quickly • Consistency issues between different models • Rate limiting across multiple AI providers |
| Tools: Retool + PERN Stack | • Retool: Rapid AI integration prototyping • PERN Stack: Proven scalability, pgvector support | • Migration complexity from Retool to PERN • Feature parity challenges in custom implementation |
Overall Stack Assessment:
- Best suited for: AI-first applications requiring rapid prototyping with production scalability
- Key challenge: Managing dual-track development (Retool MVP → PERN production)
- Primary risk: AI cost optimization and model coordination complexity
The Critical Insight: AI Success Requires Dual-Track Engineering
The most important lesson from Checkatrade Labs' real deployment is that successful AI implementation demands a dual-track approach: rapid prototyping for validation alongside production-ready architecture for scale.
Why This Matters:
- 75% cost reduction in drone surveys wasn't achieved through perfect initial architecture—it came from iterative validation using Retool prototypes before committing to PERN stack production systems
- Traditional single-track development fails because AI requirements are too unpredictable for upfront architectural decisions
- The UK's most complained-about trade (roofing) is being transformed not by theoretical AI, but by proven systems already processing real customer needs
Three Non-Negotiable Technical Realities:
- AI Model Coordination is the Hidden Complexity
- Managing Claude/GPT/Clinebot/Devin requires sophisticated orchestration
- Single AI vendor approaches create dangerous dependencies
- Cost optimization across multiple AI APIs becomes a primary engineering concern
- TypeScript is Essential, Not Optional
- AI data flows are too complex for runtime type discovery
- Full-stack type safety prevents cascade failures in AI pipelines
- The PERN stack's TypeScript adoption path determines AI system reliability
- Vector Databases Are the New Performance Bottleneck
- Traditional database optimization doesn't apply to AI similarity search
- PostgreSQL + pgvector requires specialized indexing strategies
- Real-time AI matching at scale depends on vector operation performance
The Bottom Line: AI isn't disrupting trades through better algorithms—it's succeeding through better engineering practices that can handle the inherent unpredictability of machine learning in production environments. Checkatrade's 75% cost reduction proves that the competitive advantage goes to teams who master the dual-track development pattern, not necessarily those with the most sophisticated AI models.
