What can agents see?
Paste your store URL. Colter probes 30+ signals and shows what AI agents can find, what they can't, and what needs a live test.
Read-only. No admin access. Results in seconds.
Instant readiness scan.
Free, always.
Paste a URL. Colter probes public protocol manifests, structured data, buying surfaces, and WebMCP tools — then separates verified evidence from gaps that need runtime testing.
30+ signals across 5 dimensions
Every scan covers the public surfaces AI agents use to discover, evaluate, and prepare to buy from a store.

Works for merchants, agencies, and developers
Merchants
- Scan in 30 seconds, no technical knowledge needed
- Plain-English verdict: what works, what doesn't, what to fix first
- Share results with your dev team or agency
Agencies
- Scan client stores for upsell opportunities
- Batch scan a portfolio to prioritize work
- Quantify the gap between current state and agent-ready
Developers
- CLI and API for CI/CD integration
- MCP tool for AI-assisted development workflows
- Detailed protocol-level diagnostics
Works from CLI, API, and MCP
AI agents discover and invoke tools programmatically. Developers get the same access from the command line.

Common questions
What does Check actually scan?
Read-only scan of HTML, headers, robots.txt, structured data, and protocol endpoints. No admin access needed, safe for production.
How long does a scan take?
30 seconds on average. Results include a score, dimension breakdown, and prioritized fix plan.
Is Check free?
Yes, always. 3 scans per day on the free tier. No account required for your first scan.
What protocols does Check look for?
UCP (Google), ACP (ChatGPT), MCP (Claude), WebMCP (browser agents), plus JSON-LD, llms.txt, and AGENTS.md.
What's a good score?
75+ means strong public readiness evidence. Runtime cart, checkout, and payment behavior should still be validated with agent journeys before stronger claims.
Found gaps? Fix them.
Check shows what's missing. Fix generates a platform-specific preview, ranked by estimated readiness lift.
