Server Details
Pay-per-call DNS/TLS truth and npm/PyPI breakage checks via x402. No account or API key.
The last two health checks of this connector failed. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.

Scored across 6 tools
Most tools are clearly distinct. However, blacksignal_check_upgrade_safety and blacksignal_run_canary both analyze package breakage, which could cause confusion. Their descriptions and pricing help differentiate, but there is some overlap.
All tool names use consistent snake_case and follow a verb_noun or noun pattern. Prefixes like blacksignal_ and dns_truth_ are used uniformly, making the naming predictable and readable.
With 6 tools, the count is well-scoped. Each tool serves a clear purpose, and the set covers the server's offerings without being excessive or insufficient.
The tool surface appears complete for the server's domain: it provides a catalog, a suite of BlackSignal package analysis tools, DNS analysis, and job status checking. No obvious gaps are present.
