Processes

1. MCP Server Development with Security Hardening

• **Source**: Enterprise Security Framework and FastMCP Integration patterns
• **Placement**: specializations/shared/mcp-server-development-hardened.js
• **Description**: End-to-end MCP server development with enterprise security: validate requirements → generate FastMCP template → implement security hooks → inject validation → audit for code injection vulnerabilities → deploy with monitoring.

2. Multi-Agent MCP Development Workflow

• **Source**: 8 specialized sub-agents and Dual-Mode Architecture
• **Placement**: specializations/shared/multi-agent-mcp-development.js
• **Description**: Coordinated development using specialized sub-agents: assign domain-specific agents → coordinate via hybrid markdown/programmatic approach → integrate outputs → validate protocol compliance → security review.

Plugin Ideas

• **MCP Development Suite**: Enterprise-grade MCP server development environment with 8 specialized sub-agents, security validation, and FastMCP templates.
