Server Details
Programmatic-advertising supply verification: ads.txt, schain, ATAP receipts, cross_lens_verify.
Glama couldn't complete the latest health check. 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.

TDQS
A4.5/5.0
Scored across 12 tools
Disambiguation5/5
Each tool targets a distinct resource and action: entity scoring, batch scoring, ads.txt checks, app bundle verification, IP classification, schain verification, supply path verification, supply graph traversal, cross-lens verdicts, and ATAP lifecycle steps. Even the several verify_* tools are clearly separated by input type and described purpose.
Naming Consistency4/5
The vast majority follow a consistent sigil_<verb>_<object> pattern (e.g., sigil_verify_ads_txt, sigil_score_entity, sigil_atap_witness). The sole exception is cross_lens_verify, which breaks the prefix and places the verb at the end, creating a minor inconsistency.
Tool Count5/5
Twelve tools is a well-scoped count for the server's dual purpose of supply-chain verification and ATAP compliance. Each tool covers a distinct workflow, and the number is comfortably within the ideal 3-15 range.
Completeness5/5
The toolset covers the full lifecycle: single and batch scoring, supply graph traversal, every major verification check (ads.txt, app bundle, IP, schain, supply path), composite cross-lens verdicts, and the complete ATAP process (register, witness, receipt). No obvious dead ends or missing operations are apparent.
