+Netlify Functions API for the allocation engine trading system.
+
+## Workflows
+
+### Screenshot Upload Pipeline (Client → Server → Local)
+
+A two-host workflow where any machine can upload screenshots to a shared blob store, and a listener on this machine downloads them locally.
+
+**Architecture:**
+- **Client (any machine):** watches ~/Screenshots for new macOS screenshots, uploads to Netlify Blobs via mcp-context API
+- **Server (Netlify):** mcp-context endpoint stores images in the "oncall" blob store with unique timestamped keys
+- **Listener (this machine):** polls the API for new entries and copies them to ~/Documents/Screenshots
+
+#### 1. Upload screenshots from this machine
+
+```bash
+# One-time setup: redirect macOS screenshots to ~/Screenshots
+mkdir -p ~/Screenshots
+defaults write com.apple.screencapture location ~/Screenshots
+killall SystemUIServer
+
+# Start the watcher
+NETLIFY_AUTH_TOKEN=nfp_EJhNguVjnSF5dF2KnJjxPyU6Ghq9nsVE7201 npm run watch-screenshots
+```
+
+Verify: take a screenshot (Cmd+Shift+3), expect `✓ Uploaded` within ~2s.
+
+#### 2. Upload from another machine
+
+```bash
+# Upload a screenshot manually via curl
+curl -X PUT \
+  "https://route-runtime-service.netlify.app/api/mcp-context?service=allocation-engine-2.0&date=$(date +%Y-%m-%d)" \
+  -H "Authorization: Bearer nfp_EJhNguVjnSF5dF2KnJjxPyU6Ghq9nsVE7201" \
+  -H "Content-Type: image/png" \
+  --data-binary @screenshot.png
+```
+
+#### 3. List uploaded screenshots
+
+```bash
+curl -s "https://route-runtime-service.netlify.app/api/mcp-context?service=allocation-engine-2.0" \
+  -H "Authorization: Bearer nfp_EJhNguVjnSF5dF2KnJjxPyU6Ghq9nsVE7201" | python3 -m json.tool
+```
+
+#### 4. Download latest to ~/Documents/Screenshots
+
+```bash
+mkdir -p ~/Documents/Screenshots
+curl -s "https://route-runtime-service.netlify.app/api/mcp-context?service=allocation-engine-2.0" \
+  -H "Authorization: Bearer nfp_EJhNguVjnSF5dF2KnJjxPyU6Ghq9nsVE7201" \
+  | python3 -c "
+import json, sys, base64, os
+data = json.load(sys.stdin)
+log = data.get('latest_log', {})
+if isinstance(log, dict) and log.get('type') == 'image':
+    img = base64.b64decode(log['data_base64'])
+    out = os.path.expanduser(f'~/Documents/Screenshots/{log[\"filename\"]}')
+    open(out, 'wb').write(img)
+    print(f'Saved: {out}')
+else:
+    print('Latest entry is not an image')
+"
+```
+
+### Key Details
+
+- **Auth token:** `NETLIFY_AUTH_TOKEN` env var (same token used by both client uploads and server-side blob storage)
+- **Blob store:** Netlify Blobs, store name `oncall`, site `3d014fc3-e919-4b4d-b374-e8606dee50df`
+- **Key format:** `{service}/{date}/{unix_timestamp}.{ext}` — each upload gets a unique key, no overwrites
+- **Supported formats:** image/png, image/jpeg
+- **Polling:** 250ms for first 10s (fast startup), then 1s intervals
+- **macOS TCC:** uses Spotlight (`mdfind`) to discover screenshots, bypassing Desktop permission restrictions

+
