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
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability73
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management50
- Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

- 27 Oct 26 +1
- The server rewrote its instructions, which are the text every model session reads security
- Tool “ask_mike” rewrote its description, which is the text the model reads security
- Server version: 1.0.2 → 1.0.3 functional
- “ask_mike” reworded the description of “question” cosmetic

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 →
ask_mike Ask Klondike Mike about a mining company ~175
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.
| Name | Type | Req | Description |
|---|---|---|---|
| question | string | yes | The question, in plain English, naming the company. For example: "Explain Harcourt's published valuation of Barrick." |
No output schema declared.
No examples provided.
get_published_nav Harcourt's published NAV for a covered miner ~126
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.
| Name | Type | Req | Description |
|---|---|---|---|
| ticker | string | – | Ticker or company name, for example "SA", "Seabridge" or "IVN". Omit to list every covered company. |
No output schema declared.
No examples provided.
How do I install the Harcourt Valuations MCP server?
Harcourt Valuations is a hosted endpoint at https://mcp.harcourtvaluations.ai/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.
