## 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**: 46/100
  - 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 7 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 check failed: the endpoint is reachable over plaintext HTTP.
  - 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**: 45/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 935 tokens (~38/item across 24 items; 7 tools + 17 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**: 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 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 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.

## Common questions

### What is the HealthStylz Clinical Nutrition & Circadian Environment MCP server?

HealthStylz Clinical Nutrition & Circadian Environment MCP is listed in the public MCP registry as io.github.harrybuild/healthstylz-mcp. Clinical nutrition, NIH supplement RCTs, USDA macros, and circadian curtain & herb specs. This page covers its hosted endpoint (https://healthstylz.com/api/knowledge/mcp).

### Is the HealthStylz Clinical Nutrition & Circadian Environment MCP server safe to use?

HealthStylz Clinical Nutrition & Circadian Environment MCP scores 52 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the HealthStylz Clinical Nutrition & Circadian Environment MCP server expose?

HealthStylz Clinical Nutrition & Circadian Environment MCP exposes 7 tools: get_daily_wellness_brief, search_healthstylz_articles, lookup_supplement_evidence, calculate_ag1_vs_multivitamin, get_curtain_guides, and 2 more. Their descriptions and schemas cost roughly 662 tokens of context every time the server is loaded.

### Does the HealthStylz Clinical Nutrition & Circadian Environment MCP server require authentication?

No. We connected to HealthStylz Clinical Nutrition & Circadian Environment MCP without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the HealthStylz Clinical Nutrition & Circadian Environment MCP server still maintained?

HealthStylz Clinical Nutrition & Circadian Environment MCP is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the HealthStylz Clinical Nutrition & Circadian Environment MCP server?

VerifyMCP ran 11 checks on HealthStylz Clinical Nutrition & Circadian Environment MCP, covering TLS certificate, HTTPS, HSTS header, DNSSEC and 7 more. 2 items could not be completed, a gap on our side rather than a finding about HealthStylz Clinical Nutrition & Circadian Environment MCP: Authorization and Stability. One category scores 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
