Read-only TypeScript MCP server for MongoDB-backed ERP analytics. Exposes safe tools for listing collections, reading schema/relationships, and running guarded find/aggregation queries with catalog validation, sensitive-field filtering, query limits, and blocked write/destructive operations.

Scalable FastAPI + LangGraph backend for an ERP AI analytics assistant. It receives chat queries, plans safe read-only analytics, calls a local Node.js MCP server for MongoDB schema/data tools, verifies results, and returns structured answers to the frontend.
