Top fixes

Checks tagged “emerging” are 2026 agent-protocol standards most of the web hasn’t adopted yet — adopting early is an edge, not a defect.

warnPage titleReadability

<title> is 89 characters; keep it under 70 so it isn't truncated.

Fix: Add a concise <title> tag. Agents often cite it verbatim.

warnStructured data validatesStructured data

1 recommended-field warning(s). First: Organization recommends "logo" (improves agent comprehension).

Fix: Validate your JSON-LD with Google Rich Results test. Fix missing required properties.

warnTime to first bytePerformance

TTFB 573ms. Acceptable.

Fix: Agents time out aggressively. Use edge caching for anonymous requests to cut TTFB below 800ms.

warnText-to-markup ratioReadability

Visible text is 14.7% of HTML weight (15025/102012 bytes). Low. Markup may be crowding out agent-usable text.

Fix: Heavy ad or navigation markup crowds out agent-usable text. Aim for a text-to-DOM ratio above 15%.

failMCP server cardemergingDiscoverability

No valid MCP Server Card at /.well-known/mcp/server-card.json. Publish one so agents can discover your tools without HTML scraping.

Fix: Publish an MCP Server Card describing the tools your site exposes. Agents discover capabilities via `/.well-known/mcp/server-card.json`. See modelcontextprotocol.io for the schema.

failOAuth authorization metadataemergingDiscoverability

No RFC 8414 metadata at /.well-known/oauth-authorization-server. Agents that act on behalf of users need this to discover your authorization endpoints.

Fix: Expose OAuth metadata at `/.well-known/oauth-authorization-server` per RFC 8414. Required for agents that need to perform user-authorized actions on your site.

Qualifies for certificationSilver

This score clears the Silver threshold (80+). Certification turns it into a dated, publicly verifiable attestation — a verification URL, an embeddable badge, and weekly monitoring for a full year. Scores under 70 can’t buy this, which is what makes displaying it mean something.

PlanetScale powers Tier 0 databases at: Read case study Read case study Read blog post Read case study Read blog post Read case study Read case study Read case study We chose PlanetScale to host our most demanding Vitess and Postgres workloads, doing millions of queries per second on hundreds of terabytes of data. – Sualeh Asif - Chief Product Officer @Anysphere (Cursor) Vitess Postgres Neki Vitess allows MySQL databases to scale horizontally through explicit sharding — enabling a shared nothing architecture distributing data across thousands of nodes, all routed through a single database connection. Vitess was developed at YouTube by the founders of PlanetScale to scale their main MySQL database to petabytes of data on 70,000 nodes across 20 data centers. Now maintained and managed by PlanetScale, Vitess powers the databases of some of the web&#x27;s largest properties: Slack, HubSpot, Blizzard, Etsy, GitHub, Block, Bloomberg, Yelp, and more. ┌────────────────────────────────┐ │░░░░░░░░░░░░░VTGate░░░░░░░░░░░░░│ └────────────────────────────────┘ │ ─ ─ ─ ─ ─ ┴ ─ ─ ─ ─ ┐ │ │ ▼ ▼ ╔═══════════╗ ╔═══════════╗ ║ ║ ║ ║ ║ Primary ║ ║ Primary ║ ║ ║ ║ ║ ╚═══════════╝ ╚═══════════╝ │ │ ─ ─ ┴ ─ ─ ─ ─ ┴ ─ ─ │ │ │ │ ▼ ▼ ▼ ▼ ┌───────┐ ┌───────┐ ┌───────┐ ┌───────┐ │Replica│ │Replica│ │Replica│ │Replica│ └───────┘ └───────┘ └───────┘ └───────┘ ┌──────────────────────────────────┐ │░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ │░░░░░░░░░░░░░░VTGate░░░░░░░░░░░░░░│ │░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ └──────────────────────────────────┘ │ ┌ ─ ─ ─ ─ ─ ─ ─ ─ ─ ┼ ─ ─ ─ ─ ─ ─ ─ ─ ─ ┐ │ │ │ ▼ ▼ ▼ ╔═══════════╗ ╔═══════════╗ ╔═══════════╗ ║ ║ ║ ║ ║ ║ ║ Primary ║ ║ Primary ║ ║ Primary ║ ║ ║ ║ ║ ║ ║ ╚═══════════╝ ╚═══════════╝ ╚═══════════╝ │ │ │ ─ ─ ┴ ─ ─ ─ ─ ┴ ─ ─ ─ ─ ┴ ─ ─ │ │ │ │ │ │ ▼ ▼ ▼ ▼ ▼ ▼ ┌───────┐ ┌───────┐ ┌───────┐ ┌───────┐ ┌───────┐ ┌───────┐ │Replica│ │Replica│ │Replica│ │Replica│ │Replica│ │Replica│ └───────┘ └───────┘ └───────┘ └───────┘ └───────┘ └───────┘ ┌─────────────────────────────────────────────────────────┐ │░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ │░░░░░░░░░░░░░░░░░░░░░░░░░VTGate░░░░░░░░░░░░░░░░░░░░░░░░░░│ │░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░│ └─────────────────────────────────────────────────────────┘ │ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ┼ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ │ │ ▼ ▼ ▼ ╔═══════════════════╗ ╔═══════════════════╗ ╔═══════════════════╗ ║ ║ ║ ║ ║ ║ ║ ║ ║ ║ ║ ║ ║ Primary ║ ║ Primary ║ ║ Primary ║ ║ ║ ║ ║ ║ ║ ║ ║ ║ ║ ║ ║ ╚═══════════════════╝ ╚═══════════════════╝ ╚═══════════════════╝ │ │ │ ┌ ─ ─ ─ ─ ─ ─ ┐ ┌ ─ ─ ─ ─ ─ ─ ┐ ┌ ─ ─ ─ ─ ─ ─ ┐ ▼ ▼ ▼ ▼ ▼ ▼ ┌───────────┐ ┌───────────┐ ┌───────────┐ ┌───────────┐ ┌───────────┐ ┌───────────┐ │ │ │ │ │ │ │ │ │ │ │ │ │ Replica │ │ Replica │ │ Replica │ │ Replica │ │ Replica │ │ Replica │ │ │ │ │ │ │ │ │ │ │ │ │ └───────────┘ └───────────┘ └───────────┘ └───────────┘ └───────────┘ └───────────┘ Our migration to Vitess is more than just a technological upgrade; it&#x27;s a strategic move to future-proof our database architecture for the next decade and beyond. – Ryan Sherlock @Intercom PlanetScale Postgres starts at $5 per month and gives you a fully managed PostgreSQL cluster built for performance and reliability, offering first-class tooling without sacrificing developer experience.

Track this score

Get this report by email, then a heads-up when planetscale.com’s agent-readiness actually changes — a check regressing, or the composite dropping.

Two things never trigger an email: a score change caused by us publishing a new rubric, because that is a different instrument rather than a change to your site, and movement explained only by timing-derived checks, which shift run to run on a site nobody touched.

Want it on your own schedule, with Slack or a webhook instead of email? Score-drift monitoring is on every paid plan.

This score says whether an AI agent could read planetscale.com. AI traffic analytics says whether one actually came — and which pages turned it away.
