Can't be undone 1Claude Code: ask
  • purchase_personaGenerate a checkout URL on authority.md for purchasing one or more frameworks, Tools, Playbooks, or Bundles.No findings

    Why it is in this group

    • The name "purchase_persona" says "purchase": a word that usually means money moves, which cannot be taken back.
    Description, as the server wrote it
    Generate a checkout URL on authority.md for purchasing one or more frameworks, Tools, Playbooks, or Bundles. Accepts 1-50 slugs (personas, Tools, and/or Playbooks, mixed carts allowed). To purchase a Bundle, pass all 10 of its persona slugs (get them from get_persona_details on the bundle slug — they will land on the $29.99 step-pricing tier automatically). Returns a URL the user follows to a checkout page hosted by authority.md that processes payment securely via Stripe. Personas use step pricing; Tools have individual prices; Playbooks are a flat $12.99 each. For current prices call get_persona_details per slug or read https://authority.md/products.json. Confirm with the user which items they want and the total cost BEFORE calling this tool.

  • get_persona_detailsGet the full details for a specific product on authority.md — a persona framework, a functional Tool, a Playbook, or a curated Bundle.No findings

    Why it is in this group

    • The name "get_persona_details" says "get": a word for reading.
    Description, as the server wrote it
    Get the full details for a specific product on authority.md — a persona framework, a functional Tool, a Playbook, or a curated Bundle. Use after search_personas to show complete information before purchase. Returns metadata, a 'type' field, and a preview of the content. Accepts persona slugs (e.g. 'warren-buffett'), Tool slugs (e.g. 'decision-brief'), Playbook slugs (e.g. 'invoice-chase'), and Bundle slugs (e.g. 'founder-stack'). For bundles, returns the full list of persona slugs needed to call purchase_persona.
  • list_categoriesList all categories of thinkers available on authority.md.No findings

    Why it is in this group

    • The name "list_categories" says "list": a word for reading.
    Description, as the server wrote it
    List all categories of thinkers available on authority.md. Use when the user wants to browse by domain (Investor, Tech Visionary, Philosopher, etc.) rather than search by name.
  • search_personasSearch the authority.md marketplace.No findings

    Why it is in this group

    • The name "search_personas" says "search": a word for reading.
    Description, as the server wrote it
    Search the authority.md marketplace. It carries four product types: persona thinking frameworks (e.g. Warren Buffett), hand-built functional Tools (e.g. Strategic Email — procedures for recurring tasks such as difficult emails, hiring, and pricing), Playbooks (systematically produced single-job procedures at a flat $12.99, e.g. Invoice Chase), and curated 10-persona Bundles (e.g. founder-stack, engineers-stack — $29.99 each). Use when the user asks about a specific person, a category, a task they want help with, or wants recommendations. Each result includes a 'type' field ('persona', 'skill', 'playbook', or 'bundle'), slug, focus, and price. For current prices read https://authority.md/products.json.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
