### Description (declared)

# spectr-mcp

MCP server that exposes [Spectr](https://spectr.to)'s spec-generation pipeline as a tool any MCP client can call. Hand it an App Store URL or a local MP4 of an app, get back a production-ready `spec.md` precise enough to build a clone from.

```
See an app. Ship an app.
```

## What it does

One tool, `generate_spec(source, ...)`:

- **`source`** — an App Store URL (e.g. `https://apps.apple.com/us/app/doordash/id719972451`) or an absolute path to a local MP4 screen recording.
- Returns a structured 7-section markdown spec covering app overview, navigation, screens, components, design system (with exact hex/px/weight values), implementation notes, and a Claude Code prompt the developer can paste.
- Targets Expo SDK 54 / React Native / iPhone 15 baseline.

Typical run: 2–5 min for App Store URLs, 5–10 min for MP4 recordings.

## Two ways to install

### Hosted (recommended) — Claude web app connector

Open Claude → Settings → Connectors → Add a custom connector → paste:

```
https://mcp.spectr.to
```

No key, no install, no env vars. The hosted MCP runs on Spectr's Anthropic key; you just paste the URL and start asking Claude to generate specs.

### Local (developer install) — stdio via Claude Code

If you have **Claude Code** installed and logged in (`claude login`), you can also run the MCP locally as a stdio subprocess. Uses your existing Claude Pro/Max subscription — no API key needed.

### Claude Code

```bash
claude mcp add spectr -- uvx spectr-mcp
```

Or for local development against this repo:

```bash
claude mcp add spectr -- uvx --from /path/to/spectr spectr-mcp
```

### Other clients (Cursor, Codex, custom MCP hosts)

Any client that supports MCP stdio servers can launch the local version:

```bash
uvx spectr-mcp
```

If you don't have the `claude` CLI installed and authenticated, the MCP needs an `ANTHROPIC_API_KEY` instead — set it in the launching process's environment.

Or use the **hosted** version at `https://mcp.spectr.to` if your cli…
