Proa documentation MCPサーバー

Proa Marketing

Rust SSR marketing site for Proa.

Agent interfaces

Authored document output uses typed Proa components and format-specific macros. Each page owns its HTML and Markdown implementations and shares content fields between them. The homepage composes explicit Markdown sections for the hero, render examples, showcase comparison, benchmark charts, UI catalog, capabilities, and quickstart. Markdown exposes all benchmark cases together and omits visual demo fixtures and controls. Only the existing HTML-only highlighted code fragments use the native converter. Team and Contact pages also share their data; authentication and the documentation index live in the docs module. OpenAPI and MCP input schemas use const_json! literals, while runtime discovery URLs use typed serializers. Sitemaps use xml_sync!, and 404 pages use html_sync! / md_sync!.

The homepage supports Accept: text/markdown, /index.md, and ?mode=agent. /llms.txt and /.well-known/llms.txt export that same page renderer; the focused documentation index is /docs/llms.txt. Agent catalogs live at /.well-known/ard.json and /.well-known/ai-catalog.json; the RFC 9727 API catalog is at /.well-known/api-catalog. These documents use the resolved public site URL, including Railway preview origins.

Public discovery files allow cross-origin browser reads and conditional-request preflights. The /mcp transport retains separate Host and Origin checks. Its experimental server card uses the same identity as the runtime handshake.

The skills index at /.well-known/agent-skills/index.json uses the draft Agent Skills Discovery 0.2 format with SHA-256 digests for the served SKILL.md files. These instructions describe workflows in a Proa source checkout and reference its documentation and scripts.

/api/v1/search, /api/v1/docs, and /api/v1/docs/page provide typed, paginated access to public documents. /mcp exposes the same source through the official Rust MCP SDK's stateless Streamable HTTP transport, with two read-only tools and paginated Markdown resources. /mcp/server-card describes the connection. No credentials or writes are exposed. API and MCP responses advertise an enforced shared per-instance budget of 600 requests per minute.

The optional /static/agent-tools.mjs registers the search and retrieval operations with WebMCP. Its tests run with node --test proa_marketing/tests-js/agent-tools.test.mjs. HTTP and MCP tests run through the linked pipeline:

cargo proa test --root . --locked -p proa_marketing --bin proa_marketing

See the public API guide for the external contract. The deployment smoke check also verifies the discovery index, Markdown homepage, catalog, search response, and MCP server card. Search indexing and directory listings are outside the application's control.

Proa UI homepage rail

The homepage includes the complete home-rail-section from Proa UI's marketing/src/pages/home.rs: ten inert component previews and the catalog tile. Its rendered HTML and scoped CSS are checked in, so normal builds do not need the downstream component library or another checkout. Caption links open the live catalog at ui.proa.so.

To refresh it, run the Proa UI marketing application locally, then run this from the Proa workspace root with that application's URL:

node scripts/import-proa-ui-rail.mjs http://127.0.0.1:3333

The importer preserves the source rail's order, responsive styling, themes, and keyboard navigation. It removes hydration metadata from the inert previews and scopes their styles to this section. Review both themes and the mobile layout after refreshing the snapshots.

Docs search

The Cmd+K search runs entirely in the browser. The docs build emits /docs/_search/documents.json (title, description, section, headings, frontmatter keywords, and body text per page); public/search.mjs fetches it on the first open and indexes it with a vendored Orama bundle. Ranking lives in public/search-index.mjs, which the Node battery imports too, so the score you measure is the score that ships:

pnpm run search:battery                  # local server on :5555
node scripts/search_battery.mjs --source prod
node scripts/search_battery.mjs --source path/to/documents.json --verbose
node scripts/search_battery.mjs --config tweak.json   # override DEFAULT_CONFIG keys

The fixture is scripts/search-battery.json (one obviously-right page per query, or a short list when two pages tie); its thresholds fail the run when top-1 or top-3 drops. Give a page identifiers it canonically documents with a keywords: [html_sync, html!] frontmatter list; that field is boosted above body text. Regenerate the Orama bundle after bumping the @orama/* devDependencies with pnpm run search:vendor.

The rsjs SearchModal island only owns the dialog (open, close, focus); see the ownership note at the top of public/search.mjs.

Content

Marketing docs and blog content are compiled by proa_docs_build at build time. Keep route-owned MDX in these crate-local directories:

• src/docs -> /docs
• src/blog -> /blog

Each collection follows the fumadocs-style meta.json convention for sidebar ordering and nested groups.

Local Docker Build

Build from the repository root:

docker build \
  -f proa_marketing/Dockerfile \
  -t proa-marketing .
docker run --rm -p 5555:5555 \
  -e HOST=0.0.0.0 \
  -e PORT=5555 \
  -e SITE_URL=http://localhost:5555 \
  -e PROA_BUILD_REVISION=0123456789abcdef0123456789abcdef01234567 \
  proa-marketing

Health check:

curl -fsS http://127.0.0.1:5555/healthz

Full public-contract smoke check:

python3 deploy/marketing_smoke.py \
  --url http://127.0.0.1:5555 \
  --expected-revision 0123456789abcdef0123456789abcdef01234567 \
  --attempts 1

Docker reads .dockerignore from the build context root. This repository includes a root .dockerignore so local target/, .tools/, and node_modules/ directories are not sent to the Docker daemon.

The Dockerfile builds entirely from this repository. No sibling checkout, additional BuildKit context, or registry credential is required.

The Docker builder regenerates proa_marketing/public/styles.css from proa_marketing/styles/input.css using Tailwind's standalone CLI. No Node or TypeScript workspace install is required. The build stage downloads the pinned Tailwind 3.4.18 Linux executable for the target architecture and verifies its published SHA-256 before execution, so it needs outbound HTTPS access.

The strict linked release build takes about eleven minutes on a cold local builder and can exceed Free or Trial build limits before its cache is warm. Use Hobby or higher for reliable source builds, or have CI publish a prebuilt image and point Railway at that image.

The release executable comes from the linked cargo proa build pipeline. Do not replace it with a plain cargo build: only the linked pipeline resolves the RSJS client-helper edges used by browser hydration.

Google Analytics

The site defaults to the GA4 web stream G-5XSLT8GCN3. Set GOOGLE_ANALYTICS_MEASUREMENT_ID in the production service's runtime variables to override that public measurement ID; an explicitly empty or malformed value disables analytics. Restart or redeploy after changing it. No Google OAuth token, service-account key, or Analytics API secret belongs in the site configuration.

The shared document head uses proa_third_party::google::GoogleAnalytics on marketing, docs, and ecosystem pages. The Google SDK waits until window.load so it does not compete with the page's initial resources. The application explicitly enables collection with AnalyticsConsent::Granted; the shared crate otherwise requires a consent decision from its caller. The browser bootstrap only loads Google's script on proa.so and www.proa.so, outside iframes, so localhost, Railway previews, and embedded demos do not add production page views. Google Signals and advertising personalization signals are disabled. The normal GA4 configuration sends one automatic page view per document load. See third-party integration docs for the reusable API, consent handling, and loading tradeoffs.

To verify a deployment, open a production page and check for the googletagmanager.com/gtag/js request and a google-analytics.com/g/collect request with the configured measurement ID. Confirm the visit in the property's Realtime report. Browser tracking protection may block these requests.

Deployment

Production runs on Railway at https://proa.so. All Proa applications, including proa-ui, have migrated from Coolify to Railway; Coolify is no longer an active deployment dependency.

On main, GitHub Actions builds and checks the marketing image with Cloud Build, publishes the verified image to private GHCR, and deploys its immutable digest to Railway after CI passes. See Marketing release images for the release workflow and registry configuration.

For Railway builds from source, including native PR environments, the checked-in railway.toml selects this crate's Dockerfile while keeping the repository root as the Docker build context. The shared Cargo workspace requires that context:

• Config file: /railway.toml
• Builder: Dockerfile
• Dockerfile: /proa_marketing/Dockerfile
• Health check path: /healthz
• Start command: inherited from the Dockerfile CMD

Railway injects PORT, RAILWAY_GIT_COMMIT_SHA, RAILWAY_ENVIRONMENT_NAME, and RAILWAY_PUBLIC_DOMAIN. The image provides the remaining runtime defaults. In production, absolute URLs in robots.txt and the sitemap use SITE_URL when explicitly set, then the deployment's RAILWAY_PUBLIC_DOMAIN, and finally https://proa.so. Non-production Railway environments prefer their own injected public domain so inherited production variables cannot leak the production canonical into a PR sitemap.

Production temporarily sets SITE_URL=https://proa.so while the legacy preview.proa.so alias remains Railway's injected primary domain. Standard PR environments copy base variables, so the resolver deliberately prefers the environment-specific RAILWAY_PUBLIC_DOMAIN outside the production environment. Once Railway reports proa.so as the production public domain, remove the explicit SITE_URL variable.

Do not set PORT: Railway allocates and routes to it. To override defaults, set only the values you need:

HOST=0.0.0.0
RUST_LOG=info
STATIC_DIR=/app/static
SHOWCASE_PUBLIC_DIR=/app/showcase
PROA_CONSOLE_LOAD_TESTS=0

Use SITE_URL=https://<domain> on platforms that do not provide RAILWAY_PUBLIC_DOMAIN, or for the temporary Railway production override described above.

/readyz exposes Railway's commit SHA as x-proa-revision and returns Cache-Control: no-store. PROA_BUILD_REVISION remains available as a platform-neutral explicit override.

Link and inspect the service from the repository root:

railway link --project Proa --environment production --service proa
railway status --json

Production image deployment is controlled by the deploy-release job in .github/workflows/ci.yml, which waits for the required CI gate and the verified release image.

Enable native previews in Project Settings → Environments → PR Environments. Keep the Railway-provided domain on the production service; Railway uses it to provision a distinct domain for every temporary PR environment. Do not enable Focused PR Environments yet: this service depends on crates and build inputs across the repository, not just files under proa_marketing/.

PROA_CONSOLE_LOAD_TESTS defaults to disabled for the public marketing console. Set it to 1 only for local or internal deployments where /api/loadtest should be available.

The public playground offers Proa and the deployed Hono React companions (Node and Bun), filtered by each showcase's supported engines. Setting PROA_COMPANIONS=0 leaves only Proa in the selector. The standalone playground retains the other comparison engines for local benchmarking.

The eBay playground lives at /playground/ebay/ebay-srp and uses the interactive renderer. The former /playground/ebay-rsjs/ebay-srp-rsjs URL redirects there.

The public Coolify deployment guide under src/docs/framework/ documents the optional deployment preset for users who operate their own Coolify instance. This repository uses Railway; its former Coolify and VPS preview tooling has been removed. See the retirement record.
