Current milestone

This repository currently provides a production-authenticated draft and preview workflow:

• Streamable HTTP MCP transport through Cloudflare Agents SDK

• a Cloudflare Access OAuth integration for Skydeo team identity

• manage_landing for deterministic initial page discovery and persisted legacy-draft status reads

• confirm_publish as a separate landings:publish boundary that currently fails closed without reading draft state or taking repository action

• create_draft, get_draft, update_draft, and revoke_preview MCP tools

• a typed landing-draft state machine

• one SQLite-backed Durable Object per draft

• one isolated Sandbox preview runtime per draft

• immutable SHA-256 revisions with revision-bound preview URLs

• a fail-closed preview proxy that verifies Cloudflare Access assertions before forwarding production preview traffic to a Sandbox

• a configurable preview TTL (24 hours by default), revocation, Durable Object alarms, and idempotent Sandbox cleanup

• no production publishing capability or credentials

manage_landing is the intended public workflow boundary. Its safe discovery and status paths are active now. Repository-backed create/edit requests and all publish requests fail closed without allocating a Sandbox or changing state until the canonical repository and credentials are configured. The direct-HTML draft tools remain available as legacy foundation capabilities during that migration.

The deployed /mcp route uses Cloudflare Access-backed OAuth. npm run dev explicitly enables a local-only mode, while npm run dev:access exercises the complete Access OAuth flow after local secrets are configured.

Local checks

npm run cf-typegen
npm run check

Docker is required when starting the Sandbox-backed Worker locally:

npm run dev

The first container build can take several minutes. The MCP endpoint is available at http://localhost:8787/mcp, and health is available at http://localhost:8787/healthz.

The repository includes a project-scoped Codex MCP configuration at .codex/config.toml. Trust the repository, keep npm run dev running, and restart Codex (or open a new task) to make the skydeo_landing tools available directly in the app, CLI, or IDE extension. The configuration allow-lists only status and the draft/create/update workflow; it contains no publish tool.

create_draft accepts a hostname, base revision, and complete HTML document. update_draft replaces the HTML and requires the current revision as expected_revision, preventing one editor from silently overwriting another. Every successful create or update returns a preview URL for that immutable HTML revision. Local preview URLs remain development-only capability URLs. Production preview hostnames are routed through the Worker and require a valid assertion from the wildcard Cloudflare Access preview application before Sandbox proxying. The Worker also asks the draft coordinator for an active lifecycle decision before proxying. get_draft reports active, expired, revoked, or cleaned_up, and revoke_preview fails closed immediately while cleanup proceeds durably.

Planned capability sequence

1. Create isolated repository workspaces from a pinned skydeo-landings revision instead of accepting complete HTML.

2. Add validation and structured landing-page edit operations.

3. Add a durable, explicitly approved publish workflow with production safeguards.

The MCP session is not the source of truth for a draft. Each draft is addressed by a stable Skydeo-scoped ID and stored in its own Durable Object so work survives client reconnections and can be resumed from different MCP hosts.
