AI-powered procurement engine for ADK-Rust Enterprise agents. Provides 37 MCP tools covering the full source-to-pay lifecycle — supplier management, purchase orders, RFQs, contracts, goods receipt, 3-way matching, budgets, diversity tracking, and 10 unique intelligence tools for risk scoring, price benchmarking, carbon footprint, demand forecasting, and AI-powered negotiation briefs. Feature parity with SAP Ariba and Coupa, plus capabilities neither offers.

Architecture

Procurement MCP Architecture

Key Principles

  • Source-to-pay lifecycle — from supplier onboarding through payment reconciliation.
  • AI-powered intelligence — 10 tools that no competitor offers: risk scoring, benchmarking, ESG, forecasting.
  • 3-way matching — automatic PO vs receipt vs invoice reconciliation with tolerance.
  • ESG built-in — carbon footprint estimation and supplier diversity tracking.
  • Governance — multi-level approvals, budget checks, maverick spend detection.
  • Zero configuration — starts immediately with no external dependencies.
