Overview

AI-generated overview

Lets an assistant generate SEO structured data such as JSON-LD schema, robots.txt, sitemaps, hreflang, Open Graph and meta tags.

What it does
Marsgeo is a remote MCP endpoint that produces SEO markup for web pages and sites. According to its registry description, it generates JSON-LD schema, robots.txt files, sitemaps, hreflang annotations, Open Graph tags and meta tags. It is reached over streamable HTTP at a hosted address rather than installed locally.
When to use it
Useful when an assistant needs to draft or check structured data and other SEO markup for a site, for example adding schema.org JSON-LD, building a sitemap or robots.txt, or setting up hreflang and Open Graph tags. It fits SEO and web publishing workflows rather than general coding tasks.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to the hosted endpoint. No package, environment variable or header is declared, and no authentication is declared.
Before you install
The manifest declares no authentication, so anything sent to the remote endpoint should be treated as leaving your machine; avoid submitting confidential site data. Generated robots.txt, sitemaps and meta tags affect how search engines crawl and index a site, so review output before publishing it.
