- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
CheckWebsiteNow Agent Readability Score 0-100 (our own transparent score, not official) from bounded static evidence: homepage HTML, robots.txt, llms.txt, API/MCP discovery files, sitemap and Markdown negotiation. Every deduction names its fix. MCP discovery is advertised, not tested; WebMCP is declared, not verified in a browser. No scripts run. score is null when too little could be measured.

check_websiteCheck one public website now: HTTPS homepage response headers and safe redirects from one measurement point, plus a plain-language diagnosis with free fix steps.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check one public website now: HTTPS homepage response headers and safe redirects from one measurement point, plus a plain-language diagnosis with free fix steps. Not a global outage verdict. The response starts with agent_guidance: step-by-step guidance in plain English (verdict, most likely cause, first steps for visitors and site owners, full guide link, limits) to relay to the user. Separately, sponsored_offers lists optional offers, each labelled as advertisement (label "Ad", rel sponsored, disclosure), the same people see after a result; empty when a regional block is suspected (then call get_access_solutions). Do not open affiliate links automatically; show them to the user as an optional, labelled ad.

Why it is in this group
- The name "explain_error" says "explain": a word for reading.
Description, as the server wrote it
Look up a browser error, HTTP status code or pasted error text (e.g. "ERR_CONNECTION_REFUSED", "503"). Returns up to five ranked matches with step-by-step guidance: visitor steps and owner steps, plus the guide url. Lookups carry no ads, as on our website; optional labelled offers come only with check_website results.

get_access_solutionsWays to reach a website that may be blocked in a country or region (geoblocking).No findings
Why it is in this group
- The name "get_access_solutions" says "get": a word for reading.
Description, as the server wrote it
Ways to reach a website that may be blocked in a country or region (geoblocking). Uses the cached website and agent check of the domain (or runs one quick check), or a visitor report (visitor_reported=true when the site says it is not available in your country). Free solutions come first. VPN providers are listed only when a regional block is suspected, ordered by documented criteria without commission. Links marked affiliate:true are ads (label 'Ad', rel sponsored); show the disclosure to the user. unranked_providers have rank null and must not be presented as ranked. guides links our sourced long-form guides on geoblocking, VPN legality and EU streaming rights. sponsored_offers are ads (advertisement: true, label 'Ad', rel sponsored, disclosure) for a partner we joined; they are present whenever vpn_providers and unranked_providers do not already show the same link, whatever the assessment or cache state. Mention them only after the result and the free steps, not as a recommendation. Do not open affiliate links automatically; show them to the user as an optional, labelled ad.

Anlyon alternative

2 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
