Which programming languages are supported by this skill?

The skill provides implementation patterns and boilerplate code for both Python (using FastMCP) and TypeScript (using the official MCP SDK).

What is the difference between a resource and a tool in MCP?

A resource is read-only data, such as a database schema or documentation, used to provide context to an agent. A tool is a function the agent calls to perform an action or fetch live data.

How do resources help my Claude agent perform better?

Resources give agents the 'blueprint' they need to work effectively. For example, reading a database schema resource allows an agent to construct valid SQL queries for a tool call without guessing table names.

What are the standard URI patterns for MCP resources?

Commonly used patterns include schema:// for data structures, template:// for output formats, ref:// for documentation, and config:// for settings.

API Development

Streamlines the process of adding context-rich resources like database schemas and documentation to Model Context Protocol (MCP) servers.

The MCP Resource Builder skill provides a structured framework for developers to enhance their Claude Code agents by adding persistent, readable context to MCP servers. It guides users through the architectural decision of choosing between resources and tools, offers implementation patterns for both Python (FastMCP) and TypeScript, and establishes standard URI patterns to ensure agents can efficiently navigate and understand background data like database structures, API documentation, and output templates. By defining clear boundaries between static reference data and dynamic actions, this skill helps developers build more reliable and context-aware AI agents.
