Singularity Layer MCP
Connects Claude to the Singularity Layer marketplace and x402 payment infrastructure. You get discovery tools for browsing listings and ERC-8004 agents without auth, plus authenticated operations for managing endpoints, products, and fundraiser campaigns using personal access tokens. The payment flow tools let you request 402 challenges and complete endpoint creation, top-ups, and public product purchases. Useful when you're building agent workflows that need to provision paid API endpoints, purchase marketplace items, or manage x402 assets programmatically. Auth is PAT-first with legacy endpoint key support for backward compatibility.

Install
From registry metadata$ npx add-mcp https://mcp.x402layer.cc/mcp --name singularityRun in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.
Review the command, arguments and environment values before installing. MCP servers run with your local permissions.
Other ways
