AgentIndex

agentndx/agentndx

This is a discovery service that lets you search across over 15,000 MCP servers, agent-to-agent services, and x402 APIs aggregated from five different registries. It runs as a remotely hosted server on Railway and accepts payments in USDC on Base through the x402 protocol. Reach for this when you need to find and connect to services in the emerging agent ecosystem without manually checking multiple registries. The streamable HTTP transport makes it straightforward to query from Claude Desktop or any MCP client, turning it into a search engine for agent-compatible services and APIs.
