Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to modernmustardseed.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A remote MCP server that scans public websites for speed, security, SEO and AI-crawler readiness, and scores local business presence.

What you can do: Scan a public website homepage for speed, HTTPS and certificate, security headers, domain expiry, email authentication and search basics, with a health score and fixes. Check AI search readiness: which AI crawlers robots.txt allows or blocks, llms.txt, structured data, and title and description handling. Score a local business across website, Google reviews and Google Business Profile for an overall 0 to 100 score and top fixes. Explain any individual check by id, including thresholds, why it matters and how to fix it.
When to use it: Useful when you want a quick, repeatable audit of a public site's technical health, its visibility to AI answer engines, or a local business's online presence, without setting up your own tooling.
Requirements: Remote streamable HTTP endpoint; no authentication, environment variables or headers declared. It scans public websites, so the target site must be reachable over the network.

Before you install

Scans target public websites on your behalf, so the sites you name are fetched by a third-party service. Results are advisory scores and grades, not guarantees. No credentials are requested, but avoid pointing it at internal or non-public hosts.

Installation

In SourceWeft

Open Site Check in the dashboard and add it to a workspace.
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.modernmustardseed%2Fsite-check/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

Tools

scan_website

Scan a website

Run a measured health check of a public website homepage: speed (server response, page weight, scripts, image formats), security (HTTPS, certificate expiry, security headers), domain registration expiry, email authentication (MX, SPF, DMARC), search basics (title, description, headings, indexability, sitemap), AI search readiness (structured data, AI crawler rules, llms.txt) and contact paths (tap to call, forms, analytics). Every result is measured, not judged by a model, and each warn or fail comes with a fix and an effort level. Returns a 0 to 100 website score, the top fixes, and how the page appears in a search result. Results are cached for 24 hours. Use detail "full" to include passing checks.

Parametersurlrequireddetailsections

check_ai_search_readiness

Check AI search readiness

Check whether AI assistants and answer engines can read and quote a public website: which AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended and others) its robots.txt allows or blocks, whether it publishes llms.txt, which structured data types it declares, how its title and description read, and the search and AI checks with fixes. Shares the 24 hour cache with scan_website.

Parametersurlrequired

score_local_presence

Score local presence

Score a local business on three pillars, website (45 percent), Google reviews (30 percent) and Google Business Profile (25 percent), and return an overall 0 to 100 score, a letter grade, each pillar with its verdict, and the top fixes. The website pillar comes from a live scan when a website is given. Review and profile facts (rating, review count, phone, address, hours) are supplied by the caller from the user or from a public listing; this tool does not look them up. A pillar with no facts is marked unknown and left out of the overall score rather than scored as zero.

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.
