## 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**: 14/100
  - TLS not yet verified: we couldn't open a connection to check the certificate.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS not yet verified: we couldn't read the response headers to check for it.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but we couldn't connect to verify it.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 4 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## MCP tools (6)

### `dns_truth_analyze_domain` (~78 tokens)

[$0.05 USDC/Solana per call] Passive DNS/domain truth report: nameservers, A/AAAA, MX, SPF, DMARC, DNSSEC plus certificate and deliverability signals. SSRF-safe, anonymous — no domain authorization required.

Input parameters:

- `domain` (string, required): Domain to analyze (public/passive checks only)

### `blacksignal_run_canary` (~107 tokens)

[$0.10 USDC/Solana per call] BlackSignal release-breakage canary for an npm/PyPI package: analyzes the latest release (or an explicit range) for yanks, deprecations, major version bumps, tightened runtime requirements and dependency churn — with registry evidence.

Input parameters:

- `ecosystem` (string, required): pypi | npm
- `from_version` (string)
- `package` (string, required): Package name
- `to_version` (string)

### `blacksignal_check_upgrade_safety` (~101 tokens)

[$0.05 USDC/Solana per call] Is this specific upgrade safe? Analyzes a package's from_version → to_version for breaking changes, with registry evidence. Cheaper than run_canary because the range is explicit.

Input parameters:

- `ecosystem` (string, required): pypi | npm
- `from_version` (string, required): Current version
- `package` (string, required): Package name
- `to_version` (string, required): Target version

### `blacksignal_get_breakage_feed` (~101 tokens)

[$0.01 USDC/Solana per call] Evidence-backed public npm/PyPI breakage feed from BlackSignal platform monitors. Returns only platform-public incidents; private tenant monitor findings are never exposed.

Input parameters:

- `ecosystem` (string): Optional registry filter
- `limit` (integer)
- `package` (string): Optional exact package name
- `severity` (string): Optional severity filter
- `status` (string): Optional lifecycle filter

### `get_job_status` (~37 tokens)

Check the status/result of a paid job by its job_id (the settlement tx signature). Free.

Input parameters:

- `job_id` (string, required)

### `agent_catalog` (~24 tokens)

List the payable cells/tools, their prices, input schemas and endpoints. Free.
