What problem does it solve?
This Skill helps you design and implement high-quality MCP (Model Context Protocol) servers so LLM agents can reliably use well-structured tools to complete real-world tasks with minimal confusion and wasted context.
Core Features & Use Cases
- Workflow-first tool design: Build tools that support complete agent workflows, not just thin API wrappers.
- Context-optimized outputs: Make responses concise by default, support detailed vs concise modes, and reduce token waste.
- LLM-friendly reliability: Create actionable, educational error messages and strong input/output schemas for predictable tool use.
- Language-specific implementation guidance: Follow best practices for Python (FastMCP) and Node/TypeScript (MCP SDK).
- Quality and evaluation support: Use checklists and create evaluation sets that measure whether agents can actually use your tools effectively.
Quick Start
Use this skill to plan and implement an MCP server by reading the MCP protocol spec, then drafting an implementation plan for your tools before coding.
