## 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 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 445 tokens (~222/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (2)

### `ask_mike` (~175 tokens)

Ask Klondike Mike about a mining company

Answers a plain-English question about Harcourt Valuations' published research on a covered listed mining company: its published NAV per share and price to NAV at the model date, what drives the valuation, or which companies Harcourt covers. It does not value a company at today's prices or at other metal prices. Harcourt builds NAV models asset by asset from each company's own filed technical reports (NI 43-101, S-K 1300, JORC). Answers are written by Klondike Mike, Harcourt's assistant, from Harcourt's published figures, and are not investment advice. Takes one question naming the company. Rate limited per caller per day.

Input parameters:

- `question` (string, required): The question, in plain English, naming the company. For example: "Explain Harcourt's published valuation of Barrick."

### `get_published_nav` (~126 tokens)

Harcourt's published NAV for a covered miner

Returns Harcourt Valuations' published net asset value per share, price to NAV, commodity, assets and model date for a covered mining company, or the whole coverage list when no ticker is given. A direct read of Harcourt's published figures: exact, fast and free. Each figure is valued at the metal prices of its model date, which is returned with it, not at today's prices.

Input parameters:

- `ticker` (string): Ticker or company name, for example "SA", "Seabridge" or "IVN". Omit to list every covered company.
