# UnitClock > UnitClock is for 1–20 facility self-storage operators and portfolio managers who need a defensible per-unit lien→auction clock—not a black-box recovery department. We sit on top of SiteLink and storEDGE with counsel-versioned state packs, a proof vault, SCRA checkpoint, and confirm-gated MCP tools. Not legal advice; demo packs are fixtures; we do not guarantee statutory compliance. ## Product thesis - [Home — per-unit compliance clock](https://unitclock.com/home.md): Wrongful sale is usually a missed date. Visible timelines, blockers, and operator-owned exports. ## Agents & MCP - [MCP overview for buyers](https://unitclock.com/mcp.md): Org API keys (hashed), sandbox key, OAuth client_credentials, 29 tools at `POST /api/mcp`. - [MCP & agent pricing](https://unitclock.com/pricing/mcp.md): Operator includes fair-use MCP. MCP add-on is $49/month on the same Stripe account. Sandbox is free and dry-run. ## Pricing & compare - [Pricing tiers](https://unitclock.com/pricing.md): Free → Operator → Portfolio + state packs. Monthly software; mail/SCRA pass-through. - [Compare alternatives](https://unitclock.com/vs.md): Spreadsheets, PMS reminders, managed ~$750/mo suites, Late2Lien-style noticing vs UnitClock. ## How we work - [How it works](https://unitclock.com/how-it-works): Connect FMS → install pack → daily due board → notices & proofs → auction gate → export. - [Trust & compliance posture](https://unitclock.com/trust): Renotice-on-reschedule, SCRA gate, non-statutory contact logs. - [ROI calculator](https://unitclock.com/tools/roi): DIY clock vs managed-suite floor (illustrative). ## Legal - [Disclaimer](https://unitclock.com/legal/disclaimer): Not legal advice. Packs are operational tools, not compliance guarantees. ## Machine endpoints - MCP server: `https://unitclock.com/api/mcp` (Streamable HTTP POST; 401 + RFC 9728 `resource_metadata` without bearer) - Sandbox key: `GET https://unitclock.com/api/mcp/demo-key` (Austin/Oakland, dry-run writes) - OAuth token (client_credentials only): `https://unitclock.com/api/oauth/token` - OAuth protected resource: `https://unitclock.com/.well-known/oauth-protected-resource/api/mcp` - MCP server card: `https://unitclock.com/.well-known/mcp.json` (same document at `https://unitclock.com/.well-known/mcp/server-card.json`) - Tool catalog: `GET /api/mcp` or JSON-RPC `tools/list` with a valid key - Registry scaffold: `server.json` in repo (`com.unitclock/mcp`) — publish after DNS verification (see `docs/MCP-REGISTRY.md`)
