# FDS Estimator MCP

Cloudflare-hosted MCP server for stateful fence quoting.

## What it does

- Stores quote state per `quote_id`
- Validates submitted answers against family specs
- Computes BOMs from the provided pure resolver in `mcp/engine.js`
- Exposes 4 MCP tools:
  - `start_quote`
  - `submit_answers`
  - `quote_status`
  - `finalize`

## Runtime

- Cloudflare Workers
- Cloudflare Agents MCP transport
- Durable Objects with SQLite-backed storage

## Local development

```bash
npm install
npm run typecheck
npm test
npx wrangler dev
```

The MCP endpoint is served at `/mcp`.

## Deploy

```bash
npx wrangler login
npx wrangler deploy
```

After deploy, the remote MCP endpoint is:
