📄 Official and Strategic MCP Servers for ConnectSoft AI Software Factory

MCP as Optional Tool

MCP servers are optional tools for external resource access when needed. They are NOT used for core agent-to-agent communication or orchestration, which uses event-driven architecture (Azure Event Grid/Service Bus). Agents primarily communicate via event-driven architecture using Azure Event Grid/Service Bus, not MCP. MCP servers are only used when external resource access via MCP protocol is specifically needed.

🎯 Purpose of This Document

This document provides a structured list of official, recognized, and strategically important Model Context Protocol (MCP) servers that can optionally be integrated into the ConnectSoft AI Software Factory for external resource access when needed.

Each MCP server is evaluated for its: - Alignment to ConnectSoft platform principles: Cloud-native, Event-driven, Multi-tenant SaaS, Observability-first. - Practical use for optional external resource access, artifact management, and cross-platform interoperability. - Readiness for enterprise adoption, governance, and scalability.
