Tools

• fetch ~94 tokens
  Fetch a verified public document by the canonical URL ID returned by search. Return source text, attribution and dates when available; never infer a review.
• mrx_get_started ~82 tokens
  Read MRX's current public homepage and its source-linked next-step links. This does not submit a request, create a case, or perform a human review.
• mrx_list_public_pages ~195 tokens
  Discover current public pages, including website journeys and AI guide profiles. Categories: all, articles (blog paths), ai_guides, website. Pass content_revision on subsequent pages to detect a changing inventory. Read a page before citing it.
• mrx_read_page ~122 tokens
  Read one canonical public MRX page after sitemap, hash and indexability checks. Accepts only https://mineralrightsxchange.com/ URLs returned by search. Private routes, off-site URLs, queries, fragments and redirects are rejected.
• mrx_search_guides ~192 tokens
  Search verified public MRX titles, headings and article text. Optional jurisdiction/topic filters are source-text matches, not legal conclusions. Coverage reports omissions. Do not include personal data in a research query.
• mrx_status ~56 tokens
  Check the current public sitemap/manifest, server capabilities and boundaries.
• mrx_website_capabilities ~126 tokens
  Read current website capabilities from verified public sources. Sections: overview, ai_guides, investors (Graham), human_review. Returns website descriptions, not access to chat, bookings, uploads or private cases.
