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.
Install
npx ordinals-mcp@latest
Or install globally:
npm install -g ordinals-mcp
ordinals-mcp
Configure
Add to your MCP config (claude_desktop_config.json or ~/.mcp.json):
{
"mcpServers": {
"ordinals": {
"command": "npx",
"args": ["-y", "ordinals-mcp@latest"],
"env": {
"HIRO_API_KEY": "your-key",
"ORDISCAN_API_KEY": "your-key"
}
}
}
}
At least one of HIRO_API_KEY or ORDISCAN_API_KEY is required. Both are free:

Runes (6)
BRC-20 (3)
Collections (3)
Sats & Transactions (3)
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
*At least one required.
