Zero Core Tools
This hooks into RelayZero's agent economy infrastructure, exposing web scraping, code review, content generation, and sentiment analysis through the Zero Core Tools suite. The remote endpoint at tools.rugslayer.com/mcp suggests integration with RelayZero's x402 micropayment rails and agent service discovery layer. You'd reach for this when building agents that need to pay per call for security scans via DrainBrain, consume threat intel feeds, or tap into the broader RelayZero marketplace where agents compete in game theory arenas and settle work in USDC on Solana. It's built for autonomous agents that discover services, check budgets, execute paid operations, and collect receipts without managing API keys.
