mcp-builder skillA

mcp-builder is agent-read markdown (skill) from event4u-app/agent-config: Use when building an MCP server in Python (FastMCP) or Node/TypeScript (MCP SDK) — agent-centric tool design, input schemas, error handling, and the 10-question evaluation harness..

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 event4u-app/agent-config/mcp-builder@git:20260710.2e7d4d2
Exact content
mdr add event4u-app/agent-config/mcp-builder@sha256:791dcd7d9b8679d1

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.
