M2Mcent

Overview

M2Mcent is a Model Context Protocol (MCP) server: x402 payment wrapper for AI Agents and MCP Servers. USDC settlements on Base L2. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package m2mcent-sdk speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need BASE_RPC_URL, RELAYER_PRIVATE_KEY, TREASURY_ADDRESS. The current release is v1.0.5, published under the MIT license, with source at Evozim/m2mcent-sdk on GitHub.

You'll find M2Mcent in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
