## 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 2026-09-26.

- **Endpoint Security**: 80/100
  - 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 71/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 557 tokens (~185/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-26 (score 74, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-25 (score 73, 0)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-24 (score 73, +1)

- [functional improvement] Stability: unverified → 0.03

### 2026-09-23 (score 72)

First indexed and scored.

## MCP tools (3)

### `connect` (~95 tokens)

Connect to a HenryKnows page

Connect to the HenryKnows page the person is watching (turns its light green) and get the session to pass on later calls. Call this first if the person gave you a session code; otherwise it is optional — ask_henry and search_sources connect too.

Input parameters:

- `session` (string): The HenryKnows session from an earlier result, or the session code the person gave you. Omit to start a new one.

### `ask_henry` (~151 tokens)

Ask HenryKnows

Ask HenryKnows a question about F-1/J-1 student immigration, SEVIS, OPT, CPT or related rules and get a cited answer. Ask in the person's own terms; do not add identifiers. Answers take 10–40 seconds.

Input parameters:

- `audience` (string): professional (default): precise, regulation-cited. student: plain language for the student themselves.
- `question` (string, required): The question, with the facts that matter (dates, degree level, category, employer type) and no names or ID numbers.
- `session` (string): The HenryKnows session from an earlier result, or the session code the person gave you. Omit to start a new one.

### `search_sources` (~111 tokens)

Search HenryKnows sources

Search HenryKnows' knowledge base (regulations, SEVP/USCIS guidance, Federal Register rules) and get the matching passages with their source links, so you can read and cite the text yourself. Fast; no model call.

Input parameters:

- `limit` (integer): How many passages (default 6).
- `query` (string, required)
- `session` (string): The HenryKnows session from an earlier result, or the session code the person gave you. Omit to start a new one.
