trello.com
AI agents struggle with Trello because the site lacks standard machine-readable protocols like OpenAPI documentation and MCP server configuration.

Discovery 19/22.2
API reference linked from the homepagedetailsWARN
no link to an API reference in the homepage HTML
Fix: If you have an API, link its reference from the homepage. If you don't, this check is safe to ignore.
Open Graph tags presentdetailsWARN
no Open Graph tags
Fix: Add og:title and og:description meta tags.
sitemap.xml exists and parsesdetailsWARN
served, but contains no <urlset> or <sitemapindex>
Fix: Make /sitemap.xml a valid sitemap: a <urlset> of <url><loc> entries, or a <sitemapindex> pointing at more sitemaps.
Canonical URL declareddetailsPASS
https://www.trello.com/home
Documentation linked from the homepagedetailsPASS
2 docs link(s), e.g. https://developer.atlassian.com/cloud/trello/
Homepage has a meta descriptiondetailsPASS
195 characters
Homepage has a descriptive titledetailsPASS
'Capture, organize, and tackle your to-dos from anywhere' (55 chars)
robots.txt allows agent crawlersdetailsPASS
all 6 agent crawlers may fetch /
robots.txt existsdetailsPASS
HTTP 200, 657 bytes
robots.txt points at the sitemapdetailsPASS
robots.txt has a Sitemap: line
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 28.7/33.3
llms.txt is structured markdowndetailsFAIL
/llms.txt returns HTML, not markdown
Fix: Serve /llms.txt as text/plain or text/markdown. An HTML error page at this path is worse than a 404: it looks like content.
Structured data (JSON-LD) on the homepagedetailsWARN
no JSON-LD blocks on the homepage
Fix: Add a JSON-LD block (schema.org Organization or SoftwareApplication) so agents get your name, description and links as data rather than prose.
Serves markdown when asked for itdetailsWARN
Accept: text/markdown → text/html
Fix: Optional but increasingly expected: honour `Accept: text/markdown` by serving a markdown rendering of the page, so agents skip HTML parsing entirely.
Content-to-markup ratio is reasonabledetailsWARN
ratio 0.0156 — 7801 readable chars in 498684 bytes of HTML
Fix: Most of what you serve is markup and inline script rather than content. Reduce inline payloads or server-render more text so the signal-to-noise ratio favours readers.
Docs are readable without JavaScriptdetailsPASS
2925 characters of text at /docs
Homepage responds to an agent requestdetailsPASS
HTTP 200 for / (agent UA)
Served over HTTPSdetailsPASS
https://trello.com/
llms-full.txt is publisheddetailsPASS
HTTP 200, 134723 bytes
llms.txt is publisheddetailsPASS
HTTP 200, 134723 bytes
Links in llms.txt resolvedetailsPASS
4 sampled link(s) all resolve
Same response for agents and browsersdetailsPASS
both User-Agents got HTTP 200
Homepage has readable text without JavaScriptdetailsPASS
7801 characters of text in the served HTML
No long redirect chain on the homepagedetailsPASS
0 redirect(s)
Usability 15.9/44.4
OpenAPI document publisheddetailsFAIL
/openapi.json is served but is not valid JSON
Fix: Serve a parseable OpenAPI document at /openapi.json. What is there now cannot be read by any tooling.
.well-known/mcp.json advertises an MCP serverdetailsFAIL
/.well-known/mcp.json is served but is not valid JSON
Fix: Fix the JSON at /.well-known/mcp.json — as served it cannot be parsed, so the advertisement does nothing.
agents.md is publisheddetailsWARN
/agents.md returns HTML
Fix: Serve /agents.md as markdown (text/markdown or text/plain). An HTML page here is probably your SPA catch-all route.
The /api root behaves predictablydetailsWARN
/api → HTTP 200 text/html
Fix: Serve JSON from API paths, with an accurate content-type.
Errors are machine-readabledetailsWARN
a nonexistent path returned HTTP 200, not 404
Fix: Return 404 for paths that do not exist. A 200 on a missing page makes an agent believe it found something.
A documentation endpoint respondsdetailsPASS
/docs → HTTP 200
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
MCP server lists toolsdetailsN/A
no MCP endpoint to probe

no parseable OpenAPI document

no parseable OpenAPI document
OpenAPI document is structurally validdetailsN/A
