# revid.ai: agentic web grade A

Score 56 (coverage 40 + breadth 6 + conformance 10); 4 standards observed across 4 of 9 steps; checked 2026-10-25T18:32:54Z via www.revid.ai. This grades the agent-facing files published at revid.ai, not the organisation's products.

## Manifests

| Manifest | Path | Result | Errors | Warnings |

| AI Catalog well-known file | /.well-known/ai-catalog.json | absent HTTP 404 |  |  |
| MCP Server Cards (SEP-2127) | /.well-known/mcp/server-card.json | errors | body exceeds 64 KB streaming cap (keep discovery cards compact and list tool schemas via tools/list) |  |

## Standards observed

- llms.txt: https://revid.ai/llms.txt (https://agenticweb.wiki/protocols/llms-txt/)
- OAuth Protected Resource and Authorization Server Metadata (as used for agent authorization): https://revid.ai/.well-known/oauth-protected-resource (https://agenticweb.wiki/protocols/oauth-metadata-for-agents/)
- MCP Server Cards (SEP-2127): undefined (https://agenticweb.wiki/protocols/mcp-server-cards/)
- Model Context Protocol: undefined (https://agenticweb.wiki/protocols/mcp/)

## Cheapest next steps

1. Agentic Resource Discovery: a catalog at /.well-known/ard.json lets agents discover your APIs, MCP servers and data in one fetch (https://agenticweb.wiki/protocols/ard/)
2. AGENTS.md: instructions for coding agents working on or with the site (https://agenticweb.wiki/protocols/agents-md/)
3. api-catalog: A Well-Known URI and Link Relation to Help Discovery of APIs: an RFC 9727 linkset pointing at your OpenAPI description (https://agenticweb.wiki/protocols/api-catalog-rfc9727/)

## Agent pre-flight & practical readiness

Preferred mode: `mcp` (fallback `llms_txt`). Call the MCP endpoint at https://www.revid.ai/api/mcp first. Do not scrape the HTML when a tool can answer.

Fetch: `POST https://www.revid.ai/api/mcp` POST a JSON-RPC tools/list, or server/discover on the 2026-07-28 revision, before reading HTML.

Practical readability: exa_parsable yes, markdown negotiation no, render `ssr_rich`, HTML quality `high`, first content at byte 128725 (~126 KB of head/script markup before main text), HTML-to-llms.txt token ratio 31.402×, JSON-LD SoftwareApplication, AggregateRating, Offer, WebSite, Organization, ImageObject, Place, PostalAddress, Person.

AI crawler posture: `open_to_all` · Assistant access: OpenAI `allowed`, Anthropic `allowed`, Google `allowed`, Perplexity `allowed`, Exa `allowed`.

Readiness subscores: reach 20/20, readability 22/30, capabilities 18/35, conformance 10/15, total 70/100, grade A.

## Rubric

+10 per lifecycle step with a standard observed, counting manifests that validate or that the probe rule for the standard recognises (a valid MCP server card counts for MCP; max 90); +3 per observed standard beyond the first two (max 15); conformance +15 (+10 with one manifest) minus 5 per agent-facing manifest with errors, never below 0 (security.txt is reported, not scored). Lifecycle grade: A+ >= 60, A >= 45, B >= 30, C >= 20, D >= 10. Strict 100-point composite (subscores.total_100 / subscores.grade_100): reach_and_policy (20) + readability (30) + capabilities (35) + conformance (15), where A+ >= 80, A >= 65, B >= 45, C >= 28, D >= 15.
