Complete Evalab Testing Ecosystem v1.0.0

A comprehensive Model Context Protocol (MCP) server providing 11 focused tools for systematic evalab domain testing, discovery, and end-to-end workflow validation. Built using Mastra framework with AWS Bedrock integration.

🚀 Overview

This MCP server implements the complete specification from MCP-Tools-Specification.md, offering systematic coverage of the entire evalab ecosystem through 4 organized tool categories.

🛠️ Complete Tool Arsenal (11 Tools)

Category 1: Domain Discovery 🔍

Explore and understand the evalab ecosystem:

listEvalabDomains

• Discover available domains and dependencies
• Understand input requirements and completion types
• Map domain relationships and capabilities

getEvalabDomainInfo

• Get specific domain configuration details
• Required parameters and input sources
• Capabilities and constraints analysis

Category 2: Topic Management 📝

Handle topic generation and consumption:

listAvailableTopics

• Find topics for topic-consuming domains (expert-data-collection)
• Source file tracking and display names
• Domain dependency verification

getTopicFromSession

• Extract topics from completed lesson-scoping sessions
• Validate session completion and results
• Enable seamless domain chaining

Category 3: Chat Session Management 💬

Core conversation handling:

startEvalabChat (v2.0.0)

• Begin domain workflows with proper initialization
• Topic support for chained workflows
• Clean session management

continueEvalabChat (v2.0.0) ✅

• RELIABILITY FIXED: HTTP 500 errors eliminated
• Session validation with domain extraction
• Retry logic with exponential backoff
• 45-second timeout with comprehensive error handling

getEvalabSession

• Retrieve complete session information
• Message history and task details
• Completion and result status verification

Category 4: Result Management 📊

Access and analyze domain outputs:

getSessionResult

• Access lesson-scoping and expert collection results
• Support for both session ID and latest-by-domain queries
• Comprehensive result metadata

listDomainResults

• Explore completed sessions with pagination
• Result file discovery and organization
• Session ID extraction from filenames

Category 5: Core Tools ⚙️

Foundational capabilities:

validatePrompt

• Multi-dimensional analysis using AWS Bedrock
• Clarity, safety, and effectiveness scoring
• Actionable improvement recommendations

fetchTemplate

• Domain template retrieval with version support
• Template validation and structure verification

🎯 Complete Usage Patterns

Pattern 1: Discovery & Exploration

// What domains exist?
const domains = await listEvalabDomains()

// What does expert-data-collection need?
const domainInfo = await getEvalabDomainInfo({
  domain: "expert-data-collection"
})

// What topics are available?
const topics = await listAvailableTopics({
  domain: "expert-data-collection"
})

Pattern 2: Session and Result Analysis

// Complete session workflow
let session = await startEvalabChat({
  domain: "lesson-scoping",
  message: "Create lesson about leadership"
})

// Continue until complete
while (!session.isComplete) {
  session = await continueEvalabChat({
    sessionId: session.sessionId,
    message: "Next response..."
  })
}

// Get the complete result
const result = await getSessionResult({
  sessionId: session.sessionId
})

// Extract generated topic
const topic = await getTopicFromSession({
  sessionId: session.sessionId
})

Pattern 3: Domain Result Exploration

// Explore domain results
const results = await listDomainResults({
  domain: "lesson-scoping",
  limit: 5
})

// Get latest expert collection data
const latestExpert = await getSessionResult({
  domain: "expert-data-collection",
  latest: true
})
