Enterprise Remote MCP Server with OAuth 2.0 - Sell Project

Enterprise Remote Model Context Protocol (MCP) Server engineered to bridge Anthropic Claude, Claude Code, and autonomous LLM agents directly with private cloud APIs (Payroll/HR, ERP, Banking, and internal databases). Built on Python / FastAPI adhering strictly to Anthropic's official 2024-11-05 MCP specification, this turnkey platform transforms local LLM prototypes into secure, multi-tenant cloud appliances. Core Architectural Features: • Resilient SSE Transport: Full JSON-RPC 2.0 streaming via GET /sse and re-entrant routing via POST /messages. • Multi-Tenant Isolation: Per-tenant AES-256 Fernet encrypted credential vaults ensuring zero cross-tenant data leakage. • Automated OAuth 2.0 Lifecycle: Background token refresh grants preventing conversational session drops. • Human-in-the-Loop Sentinel: Built-in guardrails intercepting high-risk capital actions (e.g. triggerpayrollrun), issuing cryptographic approval tickets. • Sub-5ms Semantic Caching: In-memory response deduplication providing 85% token compute cost reduction. • Modern Executive Web HUD: Real-time telemetry dashboard with multi-LLM failover (Claude 3.5 Sonnet, GPT-4o, DeepSeek V3). • Production Deployment: Multi-stage Dockerfile and 1-click deploy script for Google Cloud Run or AWS ECS. Deliverables: Complete source code, automated test suite, Docker configuration, and comprehensive technical documentation.
