## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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.

- **Supply Chain Security**: 13/100
  - Malware scan not yet available for this package.
  - CVE data not yet available for this package.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (122 of 124), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 30 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 458 tokens (~114/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
- **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.

### 2026-08-03 (score 47, +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.

### 2026-08-02 (score 46, +18)

- [security] Stability: Stability not yet verified: not enough scan history yet (needs a 30-day window).
- [functional improvement] Dependency health: unverified → partial
- [functional improvement] Stability: unverified → 0.20
- [functional improvement] Schema quality: unverified → excellent
- [functional improvement] MCP protocol: unverified → pass
- [functional improvement] Maintenance: unverified → pass

### 2026-08-01 (score 28, −1)

- [functional regression] Maintenance: pass → unverified

### 2026-07-31 (score 29, −9)

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

## MCP tools (4)

### `backlinks` (~137 tokens)

Backlink lookup

Look up referring domains (backlinks) for a single target domain from the Common Crawl webgraph. Returns each linking domain with host count and CrawlGraph authority score, plus the target's own authority/rank. Costs one backlinks call against the monthly quota (1,000/mo on lifetime).

Input parameters:

- `domain` (string, required): Target domain, e.g. 'stripe.com'.
- `limit` (integer): Max rows (1..10000, default 1000).
- `release_id` (string): Common Crawl release id (defaults to latest; see the releases tool).
- `sort` (string): 'authority' (default) or 'hosts'.

Output parameters:

- `cg_authority` (number|null)
- `cg_rank` (number|null)
- `domain` (string)
- `release_id` (string)
- `release_label` (string)
- `results` (array)
- `returned` (number)
- `total_linking_domains` (number)

### `gap_analysis` (~103 tokens)

Competitor backlink gap analysis

Run a competitor backlink gap analysis: find domains that link to one or more of your competitors but NOT to you. Submits an async job and polls until done (usually 5-30s). Returns every gap with `found_on` listing which competitors each domain links to. Costs one gap job against the monthly quota (50/mo on lifetime).

Input parameters:

- `competitor_domains` (array, required): 1 to 5 competitor domains.
- `my_domain` (string, required): Your domain.

Output parameters:

- `competitor_domains` (array)
- `gaps` (array)
- `my_domain` (string)
- `total_gaps` (number)

### `gap_outreach_targets` (~178 tokens)

Outreach target finder

The warm-outreach play. Runs a gap analysis, then ranks results: PRIORITY = domains linking to ALL your competitors but not you (publishers who cover your whole space and have never heard of you), SECONDARY = domains linking to 2+ competitors. Platform/CDN noise is filtered, top N priority targets are scored by authority. Use 2-3 competitors. Costs one gap job + one backlinks call per enriched target.

Input parameters:

- `competitor_domains` (array, required): 2 to 5 competitor domains (2-3 recommended).
- `enrich_top` (integer): Authority-score the top N priority targets. Default 10; each costs one backlinks call. 0 disables.
- `include_platforms` (boolean): Keep platform/CDN/social domains in the list. Default false.
- `my_domain` (string, required): Your domain.

Output parameters:

- `authority_enriched` (number)
- `competitor_domains` (array)
- `my_domain` (string)
- `platforms_filtered` (number)
- `priority_targets` (array)
- `secondary_targets` (array)
- `total_gaps` (number)

### `releases` (~40 tokens)

List Common Crawl releases

List the Common Crawl releases the API can query. Does not count against any quota. Use a release `id` with the backlinks tool to query a specific snapshot.

Output parameters:

- `releases` (array)
