This Skill solves the problem of designing and implementing high-quality Model Context Protocol (MCP) servers that LLM agents can reliably use without getting stuck or producing unsafe/poor tool behavior.
Ask the AI assistant to guide you through implementing an MCP server toolset using FastMCP or the MCP Node/TypeScript SDK, including tool schemas, annotations, error handling, testing, and an evaluation plan.

To build an MCP server, you research the MCP specification, design workflow-oriented tools with schema-driven inputs, and implement them using FastMCP for Python or the MCP SDK for Node/TypeScript, including annotations and error handling.
The Model Context Protocol (MCP) is a standard for connecting LLM agents to external tools. You need MCP when designing servers that allow agents to reliably execute specific tasks without getting stuck or producing unsafe tool behaviors.
Designing input schemas and error messages for agent tools involves using schema-driven inputs for structured data and writing actionable error messages that guide the LLM agent to recover or retry operations safely within the MCP server.
Security best practices for MCP servers include adhering to robust error handling, following secure implementation guidance, and generating read-only evaluations to verify tool usability and operational safety before deploying to LLM agents.
Yes, MCP tool design patterns apply to both Python and Node/TypeScript environments. The implementation covers schema-driven inputs, concise context usage, and actionable error messages across both FastMCP and the MCP Node/TypeScript SDK.
You create read-only evaluations to test MCP tool usability by applying the provided templates and resources to verify that LLM agents can interact with your server tools reliably without producing unsafe or poor behaviors.
