consul.io
AI agents struggle with discovery; the site lacks an llms.txt file for clear AI guidelines despite strong accessibility and documentation structure.

Discovery 21.7/22.2
Open Graph tags presentdetailsWARN
only og:title present
Fix: Add both og:title and og:description so link unfurls and agent previews show something meaningful.
API reference linked from the homepagedetailsPASS
3 API link(s), e.g. /consul/api-docs
Canonical URL declareddetailsPASS
https://developer.hashicorp.com/consul
Documentation linked from the homepagedetailsPASS
5 docs link(s), e.g. /hcp/docs/vault-radar
Homepage has a meta descriptiondetailsPASS
62 characters
Homepage has a descriptive titledetailsPASS
'Consul | HashiCorp DeveloperInteractiveInteractiveInteractive' (61 chars)
robots.txt allows agent crawlersdetailsPASS
all 6 agent crawlers may fetch /
robots.txt existsdetailsPASS
HTTP 200, 256 bytes
robots.txt points at the sitemapdetailsPASS
robots.txt has a Sitemap: line
sitemap.xml exists and parsesdetailsPASS
2 URL(s) listed
Brand findable in agent searchdetailsN/A
search-based checks are deferred — excluded from the score
Listed in an MCP registrydetailsN/A
registry lookup not implemented in v1 — excluded from the score rather than guessed
Accessibility 27.4/33.3
llms.txt is publisheddetailsFAIL
/llms.txt not served (HTTP 404)
Fix: Publish /llms.txt: a plain-markdown index that tells an agent what this product is and where the authoritative docs live. It is the cheapest high-leverage file you can add.
llms-full.txt is publisheddetailsWARN
/llms-full.txt not served
Fix: Optional but cheap: publish /llms-full.txt with your docs inlined as one markdown file, so an agent can read everything in a single fetch.
Serves markdown when asked for itdetailsWARN
Accept: text/markdown → text/html; charset=utf-8
Fix: Optional but increasingly expected: honour `Accept: text/markdown` by serving a markdown rendering of the page, so agents skip HTML parsing entirely.
Homepage responds to an agent requestdetailsPASS
HTTP 200 for / (agent UA)
Served over HTTPSdetailsPASS
https://developer.hashicorp.com/consul
Structured data (JSON-LD) on the homepagedetailsPASS
1 valid block(s)
Same response for agents and browsersdetailsPASS
both User-Agents got HTTP 200
Homepage has readable text without JavaScriptdetailsPASS
6379 characters of text in the served HTML
Content-to-markup ratio is reasonabledetailsPASS
ratio 0.052 (6379 chars of 122643)
No long redirect chain on the homepagedetailsPASS
2 redirect(s)
Docs are readable without JavaScriptdetailsN/A
/docs not served (HTTP 404) — docs may live on another path or host
Links in llms.txt resolvedetailsN/A
no llms.txt
llms.txt is structured markdowndetailsN/A
no llms.txt to parse
Usability 22.2/44.4
agents.md is publisheddetailsWARN
/agents.md not served (HTTP 404)
Fix: Publish /agents.md: what an agent may do here, which endpoints matter, auth requirements, and rate limits. It is the agent-facing counterpart to a README.
A documentation endpoint respondsdetailsWARN
/docs → HTTP 404
Fix: Serve docs at the conventional /docs path, or redirect it to wherever they live. Agents try conventional paths first.
Errors are machine-readabledetailsWARN
404 returns HTML, not a machine-readable body
Fix: Content-negotiate your errors: return a JSON body with a stable `code` (and a `next_action` where recovery exists) to clients that ask for JSON.
OpenAPI document publisheddetailsWARN
/openapi.json not served (HTTP 404)
Fix: If you have an HTTP API, publish its OpenAPI document at a predictable path (/openapi.json). It is the difference between an agent reading your contract and an agent guessing it. If you have no HTTP API, ignore this.
.well-known/mcp.json advertises an MCP serverdetailsWARN
/.well-known/mcp.json not served (HTTP 404)
Fix: If you run an MCP server, advertise it at /.well-known/mcp.json so agents discover it without being told its URL.
The /api root behaves predictablydetailsN/A
/api → HTTP 404 (no API at the conventional root)
MCP server completes the initialize handshakedetailsN/A
no MCP endpoint found to probe (none in the input URL and none advertised at /.well-known/mcp.json)
MCP tool parameters are typed and describeddetailsN/A
no listed MCP tools to inspect
Every MCP tool has a descriptiondetailsN/A
no listed MCP tools to inspect
