## 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 2026-09-27.

- **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**: 80/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 434 tokens (~144/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**: 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **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 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; 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.

## Install

### How do I install the StealthStack ARD Discovery MCP server?

StealthStack ARD Discovery is a hosted endpoint at https://stealthstack.ai/mcp?src=mcpregistry, 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.

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.

### 2026-09-27 (score 73)

First indexed and scored.

## MCP tools (3)

### `search_resources` (~176 tokens)

Search discovered agentic resources

Search the StealthStack ARD index for agentic resources (agents, MCP servers, skills, catalogs) discovered across the open web. Free-text query over name/description/tags, ranked by the index's relevance score (best match first). Optionally filter by kind, domain, or trust. Each result includes the connect URL when the publisher provides one; otherwise the inline connection or pull details.

Input parameters:

- `domain` (string): Restrict to one publisher domain (e.g. stealthstack.ai).
- `kind` (string): Restrict to one resource kind.
- `limit` (integer): Max results (1-50).
- `query` (string, required): Free-text search over name, description, and tags.
- `trust` (string): verified = the resource's URN authority matches its catalog host (domain-anchored).

Output parameters:

- `mode` (string)
- `query` (string)
- `results` (array)

### `list_resources` (~146 tokens)

Browse discovered agentic resources

Browse the StealthStack ARD index — agentic resources (agents, MCP servers, skills, catalogs) discovered across the open web. Optionally filter by kind, domain, or trust. Returns a count, a kind breakdown, and the page of resources, each with its connect URL when the publisher provides one; otherwise the inline connection or pull details. Use search_resources for a specific need.

Input parameters:

- `domain` (string): Restrict to one publisher domain (e.g. stealthstack.ai).
- `kind` (string): Restrict to one resource kind.
- `limit` (integer): Max results (1-50).
- `trust` (string): Restrict by trust status.

Output parameters:

- `byKind` (object)
- `results` (array)
- `total` (integer)

### `get_resource` (~112 tokens)

Get one discovered resource

Get the full record for one discovered ARD resource by its identifier (URN), as returned by search_resources / list_resources. Includes the connect URL when the publisher provides one; otherwise the inline connection or pull details. Also returns type, publisher, version, trust, source, description, tags, and example queries.

Input parameters:

- `identifier` (string, required): The resource URN, e.g. urn:air:stealthstack.ai:skill:parquet (urn:ai: and urn:air: are both accepted).

Output parameters:

- `found` (boolean)
- `requestedIdentifier` (string)
- `resolvedIdentifier` (string): The identifier the index matched (may use the other URN prefix).
- `resource` (object)
