## 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 2026-08-03.

- **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 not yet verified: we couldn't determine whether a plaintext access path exists.
  - 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**: 62/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 934 tokens (~133/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 97/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 91% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; 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.

### 2026-08-02 (score 64, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (7)

### `search_servers` (~212 tokens)

Search MCP Servers

Search the MCP evidence registry using a natural multi-word task (e.g. 'reliable no-auth drug interaction server with citations'). Tokenizes and expands common synonyms, ranks metadata plus observed tool descriptions, and supports operational-grade/auth/latency/category filters. Use get_trust_receipt or search_trust_evidence for security, data, citation, claim, and response evidence.

Input parameters:

- `auth` (string): Filter by authentication state (default any)
- `category` (string): Optional category filter: Dev & Code, Data & Databases, Web & Search, AI & Agents, Finance & Crypto, Communication, Productivity, Security, Commerce, Media & Design, Cloud & Infra, Science & Health,…
- `limit` (number): Max results (default 10, max 25)
- `max_latency_ms` (number): Maximum measured initialize latency in milliseconds
- `minimum_grade` (string): Worst acceptable live grade
- `query` (string, required): Keyword or task to search name/title/description for

Output parameters:

- `feedback_reminder` (string)
- `interpreted_terms` (array)
- `message` (string)
- `results` (array)

### `search_tools` (~229 tokens)

Search MCP Tools

Search across the actual tools that graded MCP servers expose (their tool names and descriptions, captured live from tools/list) — not just server metadata. Use this when you need a specific capability or data type, e.g. 'get weather', 'query postgres', 'device recall', 'FDA 510k'. Returns the matching tools with the server that offers each, its grade, and the remote endpoint so you can connect directly.

Input parameters:

- `auth` (string): Filter by authentication state (default any)
- `category` (string): Optional server-category filter: Dev & Code, Data & Databases, Web & Search, AI & Agents, Finance & Crypto, Communication, Productivity, Security, Commerce, Media & Design, Cloud & Infra, Science & H…
- `limit` (number): Max matching tools (default 15, max 40)
- `max_latency_ms` (number): Maximum measured initialize latency in milliseconds
- `minimum_grade` (string): Worst acceptable live server grade
- `query` (string, required): Capability, data type, or keyword to match against tool names and descriptions

Output parameters:

- `feedback_reminder` (string)
- `interpreted_terms` (array)
- `message` (string)
- `results` (array)

### `list_grades` (~68 tokens)

List Operational Grades

List the top graded MCP servers from the mcpqueen registry (deterministic probe grades with evidence). Returns grade, score 0-100, latency, tool count and auth state per server.

Input parameters:

- `limit` (number): Max servers to return (default 25, max 100)

Output parameters:

- `results` (array)
- `returned` (number)

### `get_server_grade` (~49 tokens)

Get Server Grade

Get the full grade and verbatim probe evidence for one MCP server, by its official registry name (e.g. 'com.healthai/radar').

Input parameters:

- `name` (string, required): Registry server name

Output parameters:

- `description` (string|null)
- `evidence`
- `grade` (string)
- `latency_ms` (number|null)
- `probed_at` (string)
- `protocol_access` (string|null)
- `provisional` (number|boolean)
- `reachable` (number|boolean|null)
- `remote_url` (string|null)
- `repo_url` (string|null)
- `score` (number)
- `server_name` (string)
- `tool_count` (number|null)
- `version` (string|null)

### `get_trust_receipt` (~67 tokens)

Get Trust Receipt

Get one MCP server's complete evidence receipt: operational grade, deterministic security/data-integrity/citation/claim observations, and reviewed real-usage field reports. Missing observations are explicitly unaudited, never treated as a pass.

Input parameters:

- `name` (string, required): Official registry server name

Output parameters:

- `audit_state` (string)
- `evidence_page` (string)
- `interpretation` (string)
- `observations` (array)
- `response_benchmarks` (array)
- `reviewed_field_reports` (array)
- `server` (object)
- `trust_dimensions` (array)

### `search_trust_evidence` (~119 tokens)

Search Trust Evidence

Search published MCP trust evidence and reviewed real-usage field reports. Use for questions such as which servers expose citations, have access caveats, make unverifiable corpus claims, or show security concerns. Returns verbatim observations with dates and source type, not a synthetic trust score.

Input parameters:

- `dimension` (string)
- `limit` (number): Max evidence items (default 20, max 50)
- `query` (string, required): Evidence, claim, source, capability, caveat, or server keyword
- `status` (string)

Output parameters:

- `interpretation` (string)
- `query` (string)
- `results` (array)
- `returned` (number)

### `submit_feedback` (~97 tokens)

Submit Field Report

Submit a field report about an MCP server you have actually used (what worked, what failed, surprising behavior). Reports are quarantined for human review and never auto-published.

Input parameters:

- `agent_name` (string): Optional: which agent/client is reporting
- `report` (string, required): The field report, 20-2000 chars, specific and factual
- `server_name` (string, required): Official registry name of the server the report is about

Output parameters:

- `message` (string)
- `server_name` (string)
- `status` (string)
