Why This One?
- 24 tools, full coverage. Inscriptions, runes, BRC-20, collections, rare sats, and marketplace data. No other Ordinals MCP covers all six categories.
- Multi-API with automatic failover. Aggregates Hiro (primary, 500 RPM), Ordiscan (fallback), and Magic Eden (marketplace). If one API rate-limits, requests automatically route to the next.
- Intelligent caching. TTLs tuned per data type -- sat rarity (24h), inscription metadata (5m), collection info (2m), balances (1m), marketplace listings (30s). Stale cache serves as last resort during outages.

| |--> Success: cache + return
| |--> Rate limited: Ordiscan (fallback) --> Stale cache (last resort)
|--> Magic Eden (marketplace-specific)
