MCP is how every major AI client — Claude, ChatGPT, Cursor, Copilot, Gemini — reaches tools and data. This kit takes you from idea to a working, installable, deployable MCP server: production-grade starters for TypeScript and Python, both transport modes, packaging, deploy scripts, and a tool-design guide that stops AI clients from misusing your tools.
Launch-week price — goes to $99 after seven days. 14-day money-back, keep the files. Instant download after checkout.
Everything the SDK READMEs assume you already know, packaged as working code instead of a reading list.
stdio and Streamable HTTP from one codebase. Sessions handled, zod-validated inputs, real error handling — not a hello-world.
Wrap an external API (runs with zero API keys) and own state with CRUD tools. Most real servers are one of these two.
Client-level smoke tests over the real protocol — in-memory transport, no network. Run them in CI from day one.
A tool result that renders an interactive dashboard inside the chat — host-themed, with text fallback for plain clients. The frontier piece no competitor ships.
Ship an installable bundle your users can click, not a repo of hopes with a README asking them to install Node first.
Dockerfile, systemd unit, and Procfile — run your remote server anywhere Node 20 runs. Remote mode is a deploy step, not a research project.
MCP went stateless on July 28, 2026. What breaks (nothing yet), what changes (a lot), and the two upgrades — SDK v2 and the new wire protocol — as separate decisions.
Naming, schemas, failure modes, and the classic mistakes that make LLMs call your tools wrong. The part nobody else sells.
Every example in this kit passes its tests before it ships. When the kit updates, the tests run again before you get the update. If an example doesn't run on a clean Node 22 install, it doesn't ship. No "coming soon", no aspirational code, no screenshots of things that don't work.
A production MCP server for your API or workflow, built to spec:
$499 flat · 3 clients per month
3 builds per month. After checkout you get the one-page brief; your slot starts at spec sign-off, delivered in 5 business days.
Send your existing MCP server repo. Within 48 hours: a written design review against the same guide this kit teaches — naming, schemas, error modes, test coverage — every finding ranked with its fix.
$149 flat · written report in 48 hours · credits toward a build
After checkout, send your repo link — the written report lands within 48 hours. Credits toward a $499 build ($350 more).
No promise here does, and anyone promising revenue from a developer kit is selling something else. What you get is a working weekend back and the patterns done right.
Because they're scattered, and the five gotchas that cost you a weekend aren't in any one of them. The kit is the weekend.
Kit updates are included in the price. The tests are what keep the examples honest when the SDK moves.
14 days, no questions, keep the files.
Kit: instant download after checkout (Stripe). Free starter: on GitHub right now. Reviews and builds: book on this page — the brief arrives right after checkout.
