# BuildMyMCPServer

> Describe your tool. We host the server. AI uses it.

Prompt-to-production MCP servers with OAuth 2.1 and Streamable HTTP. Production-grade
infrastructure for hosting Model Context Protocol servers your AI clients (Claude
Desktop, Cursor, ChatGPT) can install with a copy-paste snippet.

## Quick start

```bash
# 1. Install
pnpm install

# 2. Copy env. Defaults work for local dev. Set ANTHROPIC_API_KEY if you want real generation.
cp .env.example .env

# 3. Boot everything
pnpm dev
```

`pnpm dev` will:
1. Load `.env`.
2. `docker compose up -d --wait` postgres + redis.
3. Push the Drizzle schema (`drizzle-kit push --force`).
4. Start the full stack in parallel: web (Next.js, :3000), api (Fastify, :4000),
   generator (BullMQ worker).

Then open:

- Dashboard: <http://localhost:3000>
- API: <http://localhost:4000/health>

Click **Start building**, enter your email, copy the magic-link URL printed to the
**api** terminal output, paste it in your browser. You land on `/dashboard`. Click
**New server**, paste a prompt, and watch the build stream live over WebSocket.

If `ANTHROPIC_API_KEY` is unset, the generator returns a deterministic mock spec
(an `echo` and a `now` tool) so the full end-to-end flow stays demoable.

If Docker is unavailable, the build will fail at the deploy step with a clear error.
Otherwise: a fresh container is launched on a host port from
`RUNNER_PORT_RANGE_START…RUNNER_PORT_RANGE_END`, the server is marked `live`, and the
dashboard renders install snippets for Claude Desktop, Cursor and ChatGPT.

## Architecture

See `BuildMyMCPServer_MASTER_PROMPT.md` for the full specification and `CHOICES.md`
for decisions made during this Sprints 1–3 build.

```
apps/
  web/              Next.js 15 dashboard + marketing landing
  api/              Fastify control plane (auth, server CRUD, OAuth 2.1 AS, JWKS, WS stream)
  generator/        BullMQ worker — Claude → spec → render → docker build → local deploy
  runner-template/  Hosted MCP server template (Streamable HTTP + OAuth 2.1 RS)
packages/
  db/               Drizzle schema + client
  auth/             Magic-link + session
  types/            Shared Zod contracts
```

| Command            | Effect                                                        |
| ------------------ | ------------------------------------------------------------- |
| `pnpm dev`         | Bootstrap + parallel dev for web, api, generator              |
| `pnpm dev:no-docker` | Skip docker-compose (assumes postgres + redis already up)   |
| `pnpm build`       | Turbo build all apps                                          |
| `pnpm typecheck`   | Turbo typecheck all apps                                      |
| `pnpm lint`        | Biome check                                                   |
| `pnpm lint:fix`    | Biome check --write                                           |
| `pnpm db:push`     | Push schema to postgres (drizzle-kit)                         |
| `pnpm db:generate` | Generate SQL migration files                                  |
| `pnpm db:migrate`  | Apply pending migrations                                      |
| `pnpm stop`        | docker compose down                                           |

## Acceptance check

After `pnpm dev` is up:

- [x] `http://localhost:3000` renders the landing page.
- [x] `http://localhost:4000/health` returns `{ "ok": true }`.
- [x] Sign in via magic link (URL printed in the api terminal).
- [x] New Server → paste prompt → live WebSocket stream `queued → generating → building → deploying → live`.
- [x] If Docker is running, a container is launched and `http://localhost:<port>/mcp`
      responds **401 + WWW-Authenticate** without a token, **200** with a valid token
      issued by `/oauth/token`.
- [x] Install snippets render with copy buttons for Claude Desktop, Cursor, ChatGPT.
