api record

authority.md exposes three product types: persona thinking frameworks (~597 across 44 categories, step-priced at $4.99/$14.99/$29.99), curated 10-persona Bundles (7 stacks at $29.99 each, e.g. founder-stack, engineers-stack), and functional Tools (procedures for recurring tasks like difficult emails, hiring, pricing, decisions, and weekly reviews). Use search_personas (covers all three, with a 'type' field on each result) or list_categories to discover, get_persona_details for full info on any item including bundles, and purchase_persona to generate a checkout URL for any mix of slugs — pass…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • search_personas unknown never probed

    Search the authority.md marketplace. It carries three product types: persona thinking frameworks (e.g. Warren Buffett), functional Tools (e.g. Strategic Email — procedures for recurring tasks such as difficult emails, hiring, and pricing), 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', or 'bundle'), slug, focus, and price. For current prices read https://authority.md/products.json.

  • get_persona_details unknown never probed

    Get the full details for a specific product on authority.md — a persona framework, a functional Tool, 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'), and Bundle slugs (e.g. 'founder-stack'). For bundles, returns the full list of persona slugs needed to call purchase_persona.

      "type": "object",
      "required": [

        }
      }
    }
    arguments 12 lines
  • list_categories unknown never probed

    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.

    mcp-tool

    {
      "type": "object",
      "properties": {}
    }
    arguments 4 lines
  • purchase_persona unknown never probed

    Generate a checkout URL on authority.md for purchasing one or more frameworks, Tools, or Bundles. Accepts 1-50 slugs (personas and/or Tools, 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. 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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
