Build, harden, and debug production MCP servers with the TypeScript SDK. Use when writing or reviewing an MCP server - transports, tool schemas, errors, OAuth, token bloat, SDK migrations, MCP Apps, Registry. Assumes a server already exists.
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.
What the file says
# MCP Best Practices Decision reference for building production MCP servers with the TypeScript SDK. Not a tutorial - assumes you already have a working server and need to make it correct, fast, and secure. ## Quick Reference | Component | Current | Notes | |-----------|---------|-------| | Spec (released) | **2026-07-28** ([specification](https://modelcontextprotocol.io/specification/latest)) | Stateless/sessionless overhaul - see "Spec 2026-07-28" below and `references/spec-2026-07-28.md` | | Spec (still deployed) | **2025-11-25** | Still the bulk of deployed software and the TS client default - but Claude Code now negotiates 2026-07-28 with HTTP servers that offer it | | TS SDK (current) | **v2.3.1** (2026-10-05): `/server`, `/client`, `/core` 2.3.1; `/node` 2.1.1, `/express` + `/hono` 2.0.2, `/fastify` 2.0.1 (no longer lockstep) | `createMcpHandler` serves both eras by default; the client speaks 2025-era unless told otherwise | | TS SDK (legacy) | **v1.32.1** (`@modelcontextprotocol/sdk`) | Bug + security fixes for >=6 months after v2 GA, never a revision past 2025-11-25; source on the [`v1.x` branch](https://github.com/modelcontextprotocol/typescript-sdk/tree/v1.x) | …

How to install
mdr add tenequm/skills/mcp-best-practices@sha256:b80d127fd43e7c6dThe line at the top of this page pins the label v1.3.0, 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.
