Translation Helps MCP Server v7.19.29

A comprehensive MCP (Model Context Protocol) server that provides AI agents with access to Bible translation resources from Door43's Content Service (DCS). This server enables AI assistants to fetch, process, and intelligently work with translation helps including scripture texts, translation notes, translation words, and translation questions.

What's New in v7.19

Multi-Agent Orchestration (v7.12+)

The chat system now uses a sophisticated multi-agent architecture:

Orchestrator Agent - Analyzes queries and dispatches specialist agents
Scripture Agent - Fetches Bible text (ULT, UST translations)
Notes Agent - Gets verse-by-verse translation guidance
Words Agent - Fetches biblical term definitions
Academy Agent - Gets translation concept articles
Questions Agent - Gets comprehension questions (v7.19)
Search Agent - Semantic search across all resources

User Query → Orchestrator → [Parallel Agent Dispatch] → Synthesis → Response

Cloudflare Workers AI (v7.11)

Migrated from OpenAI GPT-4o-mini to Cloudflare Workers AI (Llama 4 Scout 17B):

Native tool calling with structured output
Edge-native inference (no external API calls)
80% code reduction in chat endpoint
Parallel tool execution for multi-tool requests

QA Citation Validator (v7.18)

Automatic verification of AI response accuracy:

Re-fetches resources to validate citations
Inline indicators: verified, uncertain, invalid
Validation summary in X-Ray panel
Prevents hallucinated quotes

Event-Driven Search Indexing (v7.6-v7.8)

Two-queue pipeline for automatic content indexing:

ZIP Upload → R2 → Unzip Queue → Index Queue → AI Search

Memory-efficient one-file-at-a-time extraction
Book-level chunking (470x fewer R2 writes)
5-7x faster search (vector-only by default)
