Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability50

71% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Partial
AI-judged instruction clarity (fair).Partial
Context-footprint check failed: tool/resource definitions use about 9735 tokens (~167/item across 58 items; 47 tools + 11 resources), over budget; trim descriptions and params. See how to fix → Fail
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management27

Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
