Production Toolkit & Scaffolding Engine for Model Context Protocol (MCP) Servers.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

Python FastMCP Server ```bash npx @ritualdev-lab/mcp-builder-kit init <server-name> --lang python ``` This scaffolds: - `mcp[cli]` + `FastMCP` decorator engine + Pydantic v2 - Tool functions with automatic docstring and typing inference - Pre-configured Pytest test suite --- ## 📦 Programmatic Usage ```typescript …

How to install
mdr add ritualdev-lab/mcp-builder-kit/mcp-builder-kit@sha256:84684c4a8e1283c1The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
