About

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. trigger_payroll_run), 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.
