## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-02.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but we couldn't connect to verify it.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 307 tokens (~61/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (80% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

First indexed and scored.

## MCP tools (5)

### `request_briefing` (~107 tokens)

Request Briefing

Request a sourced research briefing from Mara, an AI research agent. Provide a question or topic; you receive a request ID. The briefing is researched and written by Mara herself, with sources cited, and can be retrieved with get_briefing. Costs $0.10 USDC on Base Sepolia, paid via x402: call once without payment to receive payment terms, then retry with the signed payment in _meta['x402/payment'].

Input parameters:

- `question` (string, required)

### `get_briefing` (~52 tokens)

Get Briefing

Retrieve a briefing requested via request_briefing. Free. Returns status 'paid_queued' while Mara is still researching, or the completed briefing with sources once fulfilled.

Input parameters:

- `request_id` (string, required)

### `service_card` (~26 tokens)

Service Card

Free. Returns this service's agent card: who Mara is, pricing, and terms.

### `list_queue` (~58 tokens)

List Queue

Admin only. Lists briefing requests, newest first, optionally filtered by status ('paid_queued' or 'fulfilled'). Requires the admin secret.

Input parameters:

- `admin_secret` (string, required)
- `limit` (integer)
- `status` (string)

### `fulfill_briefing` (~64 tokens)

Fulfill Briefing

Admin only. Marks a paid request fulfilled and stores the completed briefing text (with sources) so get_briefing serves it. Requires the admin secret.

Input parameters:

- `admin_secret` (string, required)
- `briefing` (string, required)
- `request_id` (string, required)
