Agent Ready

Agent Ready (agent-ready.dev) is an independent AI agent-readability scanner built and maintained by Mark Lavercombe. It scores any public website against the Vercel Agent Readability Spec, the llmstxt.org specification and the agent-protocol manifests (MCP server cards, A2A agent cards, agents.json, agent-permissions.json, UCP, ACP, x402, MPP, AP2, NLWeb, RFC 9727 API catalog, Web Bot Auth, Agent Skills Discovery) — 72 checks plus a separate 23-check WCAG 2.2 accessibility sub-score — and returns a 0-100 score with per-check remediation. The same scanner is exposed as an OpenAPI 3.1 REST API at https://agent-ready.dev/api/v1 (Pro API keys, Idempotency-Key on writes, RFC 8594 Sunset policy), a hosted Streamable HTTP MCP server at /api/v1/mcp plus a no-auth MCP Apps endpoint, an A2A 1.0 agent card, a stdio MCP package and CLI on npm, JavaScript and Python client SDKs, a GitHub Action, and pay-per-scan x402/MPP micropayments in USDC on Base. Free ($0) and Pro ($19/month) plans.

Agent Ready publishes 6 API contracts indexed on the APIs.io network, including MCP API, NL Web API, Scans API, and 3 more. Tagged areas include Agents, Agent Readiness, Website Scanning, Developer Tools, and MCP.

Agent Ready’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, support, CLI, and 38 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/agent-ready-dev: open an issue to ask a question, or submit a pull request to add artifacts.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
