PageAudit

Audit a web page's technical SEO with PageAudit (pageaudit.online) and get the fix. Check title, meta description, canonical, robots and sitemap, Open Graph, headings, structured data (JSON-LD), security headers and page delivery, with evidence and a ready patch for each finding. Compare a deploy preview with production by finding code, keep pages in tabs with history and a daily watch, and run a Lighthouse lab test. Use when a task mentions SEO, meta tags, Open Graph, JSON-LD, schema.org, canonical, robots.txt, a site audit, a page that dropped from search, or checking a preview deploy.

PageAudit fetches a public page, reads what search engines and link previews read, and reports each problem with its evidence and a suggested change. The report does not certify security or accessibility.

Connect

• MCP server (preferred): https://pageaudit.online/mcp?checkout=site. Transport: Streamable HTTP. With checkout=site, the person buys on the site and the agent never pays.
• HTTP API: base URL https://pageaudit.online. Each MCP tool calls one route of this API.
• Identity: create_guest returns a guest token pa_…. Send it as guest_token (or X-Guest-Token) so the audits are tied to it and can be read again and compared.
• Discovery: GET https://pageaudit.online/api/ lists the routes, prices and limits. https://pageaudit.online/llms-full.txt has the full reference.

MCP tools

Tool	HTTP	Use it to
audit_url	POST /api/audit	Audit a URL in one call. With compare_with (an earlier audit ID of the same owner), get comparison: findings that appeared and disappeared, the score delta and regression.
get_audit	GET /api/audits/{id}	Read an audit again, with the ready fix of each finding. No new fetch, no allowance used.
get_patch	GET /api/audits/{id}/patch	Get the consolidated patch: <head> block, files to create and templates.
create_guest	POST /api/guest	Get the guest token that owns tabs and audits.
create_tab	POST /api/tabs	Save a page as a tab.
list_tabs	GET /api/tabs	List the saved pages and the latest report.
run_tab	POST /api/tabs/{id}/run	Audit a saved page again.
tab_history	GET /api/tabs/{id}/history	Read the earlier runs and what changed between them.
watch_tab	PATCH /api/tabs/{id}	Turn the daily watch on or off (needs an account).
lab_test	POST /api/audits/{id}/lab	Start a Lighthouse test through Google PageSpeed Insights.
lab_result	GET /api/audits/{id}/lab	Read the lab scores and metrics when the test ends.
list_tools	GET /api/tools	List the single-check tools (title, meta, canonical, Open Graph, JSON-LD…).
billing	GET /api/billing	Read the free allowances, options and prices.
pricing	GET /api/pricing	Read the current prices.

Rules

1. Read billing before many audits in a row. Do not use a price or an allowance from memory.
2. Never pay by yourself. If a call returns HTTP 402, show the price and https://pageaudit.online/pricing to the user. The person buys on the site.
3. To compare a preview with production: audit production with a guest token, then audit the preview with the same token and compare_with set to the production audit ID. Report comparison.broke first.
4. A finding is identified by its code. The message carries the measured value and changes between runs.
5. HTTP 502 with target_blocked or target_rate_limited means the site's firewall answered, not the page. Nothing was audited; show blocked.fix to the user.
6. If you get HTTP 429 or 503, wait for the time in Retry-After and try once more.

Examples

bash

# One audit, no token
curl -s -XPOST https://pageaudit.online/api/audit -H 'content-type: application/json' \
  -d '{"url":"https://example.com/"}'

# Preview against production, same guest token
PA=$(curl -s -XPOST https://pageaudit.online/api/guest | jq -r .token)
PROD=$(curl -s -XPOST https://pageaudit.online/api/audit -H 'content-type: application/json' \
  -d "{\"url\":\"https://example.com/\",\"guest_token\":\"$PA\"}" | jq -r .id)
curl -s -XPOST https://pageaudit.online/api/audit -H 'content-type: application/json' \
  -d "{\"url\":\"https://preview.example.com/\",\"guest_token\":\"$PA\",\"compare_with\":\"$PROD\"}" | jq .comparison
