Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Manage local CLI AI agents via tmux — start, stop, monitor, assign tasks, and schedule with cron.
Techniques for context engineering with AI agents — managing context windows, prompt structure, and knowledge organisation.
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
Building agents requires a different mindset from building applications. You're not writing features — you're writing tools that other tools use. The MCP & Agent Builder stack is for Claude Code power users who are working at this meta level: creating MCP servers, orchestrating multi-agent workflows, and building reusable skills that outlast any single project.
Claude Code power users building MCP servers, multi-agent workflows, or reusable skill libraries. If you're building something that other developers will use with Claude — or building tools that help Claude do more — this is your stack.
