Overview

AI-generated overview

Lets an assistant check whether a website is reachable, explain browser errors, and score how readable a site is to AI agents.

What you can do
Checks a public site's HTTPS homepage response headers and safe redirects from one measurement point, with a plain-language diagnosis and free fix steps. Also offers a custom Agent Readability Score (0-100) with its versioned method, plus a knowledge base for browser errors and HTTP status codes. It can list popular services' status-page information, suggest ways around regional blocking, and return public service metadata.
When to use it
Useful when a user reports a site not loading, wants a browser error or HTTP status code explained, or wants to know how readable a site is to AI agents and whether it advertises MCP discovery.
Requirements
Remote MCP endpoint over streamable HTTP; no local runtime needed. No authentication, environment variables, or headers are declared. Network access to the remote service is required.
Before you install
Results come from a single measurement point and are not a global outage verdict; the Agent Readability Score is a custom score, not an official standard, and MCP discovery is only advertised, not tested. Status-page information is editorial, not live user reports. Some lookups may include labelled commercial offers.

Installation

In SourceWeft

  1. Open CheckWebsiteNow in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.checkwebsitenow%2Fchecker/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

check_website

Check if a website is reachable

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.

Parametershostnamerequired

check_agent_readability

Agent Readability Score for a website

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.

Parametershostnamerequired

get_agent_readability_method

How the Agent Readability Score works

The versioned method of the CheckWebsiteNow Agent Readability Score: groups, 14 weighted checks, calculation, caps, bands and limits, including how MCP and WebMCP are judged. Not an official standard.

Takes no parameters.

get_access_solutions

Solutions when a website may be blocked in your country

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.

Parameterscasedomainrequiredvisitor_reported

explain_error

Explain an error message

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.

Parametersqueryrequired

list_errors

List known error messages

List knowledge-base entries, optionally filtered by category or kind.

Parameterskindcategory

Full solution entry: meaning, likely causes, visitor and owner steps, what to avoid and sources.

Parametersslugrequired

list_status_sites

List curated status pages

Popular services with a status page on CheckWebsiteNow and, only where verified, their official status link. Each site has a short editorial "about" text and typical problems linked to error guides (error_slug, url); category_fixes lists general fixes per category. Editorial, not live user reports.

Takes no parameters.

72% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
