two new MCP servers just shipped and are live in Anthropic's official MCP Registry.
x402 Bazaar MCP (powered by Coinbase)
With the help of @Coinbase, the x402 Bazaar MCP server lets your agents discover, pay for, and call any x402 service in USDC — settled on-chain. Any agent that can talk to an MCP server can now participate in the on-chain agent payments economy.
3D Agent Avatar MCP
The Avatar MCP gives Claude and any MCP-compatible client the ability to spawn a full browser-native 3D agent: on-chain identity, voice, memory, emotions, and a live x402 payment endpoint — all from a single tool call.
