Anlyon alternative

57 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.

One thing mttr knows and every way on from it, each edge marked by what made it: meaning (close in meaning, never better or cited), links (pages linking between sites, or between pages of one site, with their anchor text) or rules (code checking pages against the rulebook). Across sites: a site, a market, a line of work or a rule. Inside one named site: a page, a passage of its text, the pages that read alike with a page, or a finding, a rule a page fails, with pages elsewhere that pass it. With the reasoning behind each decision and "next", the one way on to take. Pass "onward" back as trail to keep walking. An unnamed site is shown by its code alone and has no pages here.

Each with its stages, pages read and its score the read before. With "record", one of the records instead: the fastest to answer, the most improved, the best on each stage, the best at answering first, or the biggest read in full, each with what it was counted over.

Description, as the server wrote it
Checks one live product page's structured data the way the free schema checker does: each Product, ProductGroup and Offer field by field against the fields Google lists for merchant listings (name, image, offers, price above zero, priceCurrency in ISO 4217, availability, shipping, returns, brand, GTIN, variants, ratings), each present, missing or invalid with what to do, and a guess at whether a shopper can buy on the page. Use it on one product URL per template before and after a fix. It reads only what the page publishes; Merchant Center and Google decide eligibility for any Google feature.

Before you deploy a change to a site set to approve, proposes it to the person: mttr keeps it and emails them what the change is, the rule and pages, your summary marked as your words, and an Approve and a Decline link, each working once and lapsing after 72 hours. Then wait: call mttr_proposal with the id until it says approved, and deploy only then. Declined or expired means do not deploy.

Types: LocalBusiness, Organization, Product, Article, BreadcrumbList, Service, Event, WebSite, each with the fields Google's own structured data pages mark required or recommended (Service has no Google rich result; FAQPage and HowTo are not offered, since Google no longer shows them). Empty fields are left out, never made up. It returns the JSON-LD as data and inside its script tag, ready to paste, the required fields left empty, what is not right (a price of zero, a currency not in ISO 4217, hours given in part), the recommended fields left out, and every field the type takes with its key.

Whether the certificate is valid for the name, who issued it, valid from and until with the days left (a warning under 30, a failure once expired or before it starts), the names it covers, its key and signature, the chain as sent and whether it verifies to a root Node.js trusts, the TLS version and cipher agreed, and whether TLS 1.0 and 1.1 are still accepted. Then one request each to http:// for whether it moves to https://, and to https:// for HSTS. Each finding has its state in a word and, when something is wrong, what to do. Public addresses only.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as mttr. Review it before you use it.
