Add your server

Aggregated from the official MCP Registry, Smithery, PulseMCP and other public registries, plus our own crawling and operator submissions. Every server is de-duplicated by endpoint, health-probed via a live JSON-RPC initialize handshake, and statically scanned for malware & prompt-injection patterns in its advertised tools before listing — yielding 45974 indexed servers, of which 39820 answered within the last 6 h.

  • AI Shopping tools for product search, comparison, and safe checkout Commerce Gateway — an infrastructure layer that enables open-source AI agents to participate in agentic commerce through the Universal Commerce Protocol. Our platform gives agents a hosted UCP profile registry, a secure MCP gateway, and access to commerce flows without requiring every agent to own a domain, GitHub account, or Shopify credentials. With this solution, agents can discover products, recommend options, build carts, validate them with the user, and generate checkout handoff links where the buyer completes payment safely on Shopping platform. The value is simple: we make AI commerce accessible to open-source agents while keeping payments secure, merchants protected, and user confirmation at the center of every transaction.
