Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 743 tokens (~185/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management20
- Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage89
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 67% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the authority.md MCP server?
authority.md is a hosted endpoint at https://authority.md/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_persona_details ~167
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.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | A persona slug (e.g. 'warren-buffett'), a skill slug (e.g. 'strategic-email'), or a bundle slug (e.g. 'founder-stack'). |
No output schema declared.
No examples provided.
list_categories ~45
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
purchase_persona ~165
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.
| Name | Type | Req | Description |
|---|---|---|---|
| slugs | array | yes | – |
No output schema declared.
No examples provided.
search_personas ~202
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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Optional category filter (e.g. 'Investor', 'Strategy'). |
| limit | integer | – | – |
| query | string | yes | Free-text search across name, focus, tagline, and category. |
| type | string | – | Optional filter to only personas, only skills, or only bundles. |
