ordinals-mcp

   

The most complete Bitcoin Ordinals MCP server. 24 tools covering inscriptions, runes, BRC-20 tokens, collections, rare sats, and marketplace data. Aggregates Hiro, Ordiscan, and Magic Eden APIs with intelligent caching and automatic failover.

The only alternative (ordiscan-mcp) has 25 npm downloads and covers a fraction of the surface. This server is the production-grade option.

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.

Architecture

Request --> Cache (TTL + ETag)
  |--> HIT: return cached
  |--> MISS:
      |--> Hiro (primary, 500 RPM)
      |     |--> Success: cache + return
      |     |--> Rate limited: Ordiscan (fallback) --> Stale cache (last resort)
      |--> Magic Eden (marketplace-specific)

Environment Variables

| Variable | Required | Description | |----------|----------|-------------| | HIRO_API_KEY | Yes | Hiro API key (free) | | ORDISCAN_API_KEY | Yes | Ordiscan API key (free) | | MAGIC_EDEN_API_KEY | No | Higher marketplace rate limits | | CACHE_TTL_SECONDS | No | Default cache TTL (default: 300) |
