## 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**: 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 3 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**: 78/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 457 tokens (~152/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**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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 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.

## MCP tools (3)

### `search_research` (~210 tokens)

Search the VNS research corpus

Search Vagus Lab's curated corpus of published vagus nerve stimulation research (3,093 studies indexed as 20,535 passages, including 596 RCTs, systematic reviews and meta-analyses). Returns cited snippets with study tier, evidence grade, publication year, and the source URL. Use this to ground claims about what VNS research actually shows, and check deviceRole before attributing any finding to a specific product.

Input parameters:

- `device` (string): Prefer studies involving this device. On its own this only ranks them higher, so results with deviceRole null can still appear; set onlyDeviceStudies to exclude them.
- `limit` (integer): Passages to return, 1 to 10
- `onlyDeviceStudies` (boolean): Return only passages from studies that actually used the named device. Requires device. Use this before stating that a device has evidence behind it.
- `query` (string, required): Research question or topic, for example 'taVNS effect on heart rate variability'

### `get_devices` (~75 tokens)

Get the scored device comparison

Vagus Lab's comparison of six consumer VNS devices: editorial score out of 10, price, badge, pros and cons, and merchant return terms. Scores are editorial, authored from a ten-criterion weighted methodology, and are not consumer ratings. Vagus Lab earns affiliate commission on some purchases; the payload carries that disclosure.

### `list_articles` (~81 tokens)

List published articles

Index of every published Vagus Lab article with its URL, category, and evidence grade. Fetch any article URL with the header 'Accept: text/markdown' to read the full text as clean markdown.

Input parameters:

- `category` (string): Filter by category slug, for example 'devices' or 'sleep-energy'
- `limit` (integer): Maximum articles to return
