This is a meta-registry that aggregates 25,000+ MCP servers from the official registry and Glama.ai, exposing them through search, inspect, and catalog tools. You can query by keyword, pull full metadata for any server, and check live status counts across registries. The standout feature is checkout, which detects payment protocols (x402 USDC on Base, MPP via Stripe/AgentCash, or prepaid API keys) and handles autonomous payments. Reach for this when you need programmatic discovery of MCP servers or want Claude to find and connect to tools without manual registry browsing. It's essentially a searchable index with built-in payment execution for paid MCP services.
