mcp-builder skillB

mcp-builder is agent-read markdown (skill) from mjunaidca/mjs-agent-skills: 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)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add mjunaidca/mjs-agent-skills/mcp-builder@git:20251221.f6c90d7
Exact content
mdr add mjunaidca/mjs-agent-skills/mcp-builder@sha256:5d54e2c1f1f2a828

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
