MCP: Model Context Protocol Server Development

Build, review, and debug MCP servers that expose tools, resources, and prompts to AI coding assistants. The goal is secure, well-structured servers that follow the protocol spec and don't become yet another server with preventable injection vulnerabilities.

Target versions (May 2026):

• MCP specification: 2025-11-25 (current stable; 2026-03-15 in draft)
• TypeScript SDK: @modelcontextprotocol/sdk 1.29.0 (1.x stable; 2.0.0-alpha in dev)
• Python SDK: mcp 1.27.0 (v1.26.0+)
• Protocol transports: stdio, streamable HTTP (SSE deprecated in spec 2025-03-26)

When to use

• Building a new MCP server (tools, resources, prompts)
• Adding tool handlers to an existing MCP server
• Configuring MCP transport (stdio for local, streamable HTTP for remote)
• Implementing MCP authentication (OAuth 2.1)
• Implementing MCP elicitation (interactive dialogs)
